This exfoliating ingredients guide breaks down AHA, BHA, PHA, enzymes and physical exfoliation, so you can understand how each works and choose what suits your skin.
Exfoliation sounds simple:
Remove dead skin cells → reveal smoother-looking skin.
But once you start shopping, things get complicated very quickly.
There are AHAs, BHAs, PHAs, enzyme exfoliants, scrubs, peeling gels, acid toners, exfoliating pads, masks and peels.
And almost every product promises smoother, brighter, clearer-looking skin.
The problem?
Using the wrong exfoliant — or simply exfoliating too often — can leave your skin looking worse instead of better.
The American Academy of Dermatology describes exfoliation as the process of removing dead skin cells from the outer layer of the skin. It also warns that exfoliating incorrectly can damage the skin and increase redness or breakouts.
So instead of asking:
“What is the strongest exfoliant?”
A better question is:
“What kind of exfoliation does my skin actually need?”

Exfoliating Ingredients at a Glance
| Exfoliant | Common examples | Often chosen for |
| AHA | Glycolic acid, lactic acid, mandelic acid | Dullness, rough surface texture, uneven-looking tone |
| BHA | Salicylic acid | Blackheads, whiteheads, clogged pores |
| PHA | Gluconolactone, lactobionic acid | Gentler surface exfoliation, sensitive or dry skin |
| Enzymes | Papain, bromelain | Mild surface exfoliation |
| Physical exfoliants | Scrubs, brushes, textured particles | Manual removal of surface cells |
Dew & Detail note: The category alone doesn’t determine whether an exfoliant will be gentle or strong. Concentration, formulation, frequency, pH and the rest of your routine all matter.
What Does Exfoliation Actually Do?
The outermost part of your skin continually sheds cells as part of its normal renewal process.
Exfoliation helps remove some of the accumulated surface cells.
Done appropriately, it can improve the appearance of:
- Rough texture
- Dullness
- Uneven-looking tone
- Clogged pores
- Flakiness
But your skin is not supposed to be completely stripped of its outer layer.
That outer barrier serves an important protective function.
So the goal isn’t:
Remove as much as possible.
It’s:
Remove only what your skin can tolerate without compromising its barrier.
Chemical vs Physical Exfoliation
Exfoliation generally falls into two broad categories.
Chemical Exfoliation
Chemical exfoliants use ingredients such as:
- Alpha hydroxy acids (AHAs)
- Beta hydroxy acids (BHAs)
- Polyhydroxy acids (PHAs)
to encourage the removal of surface skin cells.
The American Academy of Dermatology identifies AHAs and BHAs as examples of chemical exfoliants.
Physical Exfoliation
Physical exfoliation relies on manual friction.
Examples include:
- Scrubs
- Brushes
- Sponges
- Exfoliating cloths
- Textured particles
Physical exfoliation isn’t automatically bad.
But aggressive rubbing or coarse particles can irritate the skin, particularly if you’re already using retinoids, acids or acne treatments.
The choice isn’t necessarily:
Chemical = good
Physical = bad
A better rule is:
Gentle enough for your skin + appropriate for your concern.
1. AHA: Alpha Hydroxy Acids
AHAs are among the most widely used chemical exfoliants in skincare.
Common AHAs used in skincare include glycolic acid, lactic acid and mandelic acid.
The FDA notes that AHA-containing cosmetics are marketed for concerns including fine lines, surface wrinkles, skin texture and tone.
What Do AHAs Primarily Do?
AHAs mainly target the surface of the skin.
They’re commonly chosen for:
- Dull-looking skin
- Rough surface texture
- Uneven-looking tone
- Visible photoaging
- Surface pigmentation
Glycolic Acid
Glycolic acid is one of the most common AHAs.
You’ll find it in:
- Toners
- Serums
- Pads
- Masks
- Peels
It can be effective, but stronger products can also be irritating.
Lactic Acid
Lactic acid is another common AHA.
It exfoliates at the skin’s surface and is frequently used in products designed to leave skin looking smoother and brighter.
Mandelic Acid
Mandelic acid is another AHA, but it has a larger molecular size than glycolic acid, which can affect how it penetrates the skin.
It is often found in products aimed at people who want AHA exfoliation but may find stronger glycolic-acid formulas difficult to tolerate.
Mandelic acid may be considered for concerns such as:
- Dullness
- Uneven-looking texture
- Post-acne marks
- Mild congestion
But mandelic acid is still an exfoliating acid. A gentler reputation doesn’t mean it cannot cause irritation, especially when combined with other exfoliants or retinoids.
AHA and Sun Sensitivity
This part is important.
The FDA warns that AHA-containing cosmetic products may increase skin sensitivity to sunlight and the possibility of sunburn. It recommends sun protection while using these products and for a period afterward.
So if you’re using an AHA:
Daily sun protection is especially important.
This isn’t something to hide in tiny print at the bottom of an article.
It should be part of the decision to exfoliate.

AHA Exfoliants Worth Considering
| Product | Key Exfoliating Acids | Best For |
|---|---|---|
| COSRX AHA 7 Whitehead Power Liquid | Glycolic acid | Whiteheads, rough texture & dullness |
| By Wishtrend Mandelic Acid Gentle Exfoliating Toner | 5% Mandelic acid | Gentle exfoliation, dullness & uneven texture |
| Paula’s Choice Skin Perfecting 6% Mandelic Acid + 2% Lactic Acid Liquid Exfoliant | 6% mandelic + 2% lactic liquid exfoliant | Normal, dry & combination skin; gentler exfoliation, dullness & uneven texture |
| Paula’s Choice Skin Perfecting 8% AHA Gel Exfoliant | 8% glycolic gel exfoliant | Normal, combination & oily skin; rough texture, dullness & uneven-looking tone |
| Sunday Riley Good Genes Lactic Acid Treatment | Lactic acid leave-on treatment | Normal to dry skin; dullness, uneven texture & mature-looking skin |
| Drunk Elephant T.L.C. Framboos Glycolic Resurfacing Night Serum | 10% AHA + 1% BHA night serum | Normal, combination & oily skin; texture, congestion & experienced acid users |
2. BHA: Beta Hydroxy Acid
When skincare products say BHA, they’re usually referring to salicylic acid.
The FDA identifies salicylic acid as the BHA most commonly used in cosmetics.
Salicylic acid is particularly relevant when the concern involves clogged pores.
That’s why you commonly see it in products aimed at:
- Blackheads
- Whiteheads
- Oily skin
- Congestion
- Acne-prone skin
What Makes BHA Different?
Salicylic acid is particularly useful when dead skin cells and oil are contributing to pore congestion.
This can make it a more logical choice than a surface-focused AHA when the main concern is:
Clogged pores rather than dullness.
BHA for Blackheads and Whiteheads
If blackheads or whiteheads are your main concern, BHA is often the exfoliant worth investigating first.
But don’t mistake blackheads for dirt.
Scrubbing harder won’t necessarily clear them.
A pore can become clogged with a mixture of oil and dead skin cells. Salicylic acid helps exfoliate inside pores and reduce the buildup that contributes to congestion, which is why it is so commonly used in acne-focused products.
BHA Exfoliants Worth Considering
| Product | Key Exfoliating Acids | Best For |
|---|---|---|
| Paula’s Choice Skin Perfecting 2% BHA Liquid Exfoliant | 2% salicylic acid liquid exfoliant | Combination & oily skin; blackheads, clogged pores, excess oil & uneven texture |
| The Ordinary Salicylic Acid 2% Solution | 2% salicylic acid water-based serum | Oily & acne-prone skin; congestion, blemishes & uneven texture |
| Anua BHA 2% Gentle Exfoliating Toner | 2% salicylic acid | Clogged pores, excess oil & gentle exfoliation |
| COSRX BHA Blackhead Power Liquid | Betaine salicylate leave-on liquid | Combination & oily skin; blackheads, clogged pores & T-zone congestion |
3. PHA: Polyhydroxy Acids
PHAs are less famous than AHAs and BHAs, but they’re increasingly common in skincare.
Examples include gluconolactone and lactobionic acid
PHAs exfoliate at the skin’s surface, but research suggests they can be particularly interesting when skin is sensitive or dry.
A review of PHAs described them as compatible with clinically sensitive skin and noted humectant and moisturizing properties.
Why Are PHAs Considered Gentler?
PHAs are often positioned as gentler exfoliating options because their molecular characteristics affect how they interact with the skin.
They may be worth considering if you want:
- Gentle surface exfoliation
- Smoother-looking texture
- Hydration support
- A less aggressive acid option
Who Might Prefer PHA?
PHA may be worth considering if:
- AHAs feel too irritating
- Your skin is dry or sensitive
- You want mild surface exfoliation
- Deep pore congestion isn’t your main concern
But “gentle” doesn’t mean “impossible to irritate.”
Any exfoliating product can cause problems when overused.
PHA vs AHA
AHA and PHA overlap in what they target.
Both primarily work at the skin’s surface.
However, PHAs may be worth considering when tolerability and hydration support are priorities.
Clinical research comparing AHA and PHA regimens has found benefits with both, while some irritation measures were greater with AHA.
That doesn’t mean:
PHA is always better than AHA.
It means:
Skin tolerance matters when choosing between them.
PHA Exfoliants Worth Considering
| Product | Key Exfoliating Ingredients | Best For |
|---|---|---|
| Medik8 Press & Glow | Gluconolactone PHA liquid toner | Normal, dry & sensitive skin; gentle regular exfoliation, dullness & texture |
| The INKEY List PHA Toner | 3% gluconolactone PHA + 3% niacinamide toner | All skin types, including sensitive skin; beginners, dullness & uneven texture |
| Dr.Jart+ Pore Remedy PHA Exfoliating Serum | 7% PHA water-like serum | Normal, combination & sensitivity-prone skin; texture and those wanting a serum format |
| Glow Recipe Watermelon Glow PHA + BHA Pore-Tight Toner | PHA + BHA hydrating toner | Normal, dry & combination skin; texture, visible pores & hydration |
4. Enzyme Exfoliants
Enzyme exfoliants often contain enzymes derived from fruits.
Common examples include: papain from papaya and bromelain from pineapple.
They’re used to help loosen surface keratin and provide surface exfoliation.
You’ll often find enzymes in:
- Powders
- Masks
- Cleansers
- Peeling treatments
Are Enzymes Automatically Gentle?
Not necessarily.
“Fruit-derived” or “natural” doesn’t automatically mean non-irritating.
Some people can still experience:
- Stinging
- Redness
- Irritation
- Allergic reactions
So treat enzyme exfoliants like other active skincare products: Introduce them carefully.
Enzyme Exfoliants Worth Considering
| Product | Key Exfoliating Ingredients | Best For |
|---|---|---|
| Anua Rice Enzyme Brightening Cleansing Powder | Papain + protease + rice powder | Dullness, uneven texture & gentle exfoliation |
| By Wishtrend Green Tea & Enzyme Powder Wash | Papain + papaya extract | Excess oil, dullness & uneven texture |
| Dermalogica Daily Microfoliant | Papain + salicylic acid rice-based powder exfoliant | Normal, combination & oily skin; dullness, clogged pores & uneven texture |
| Peter Thomas Roth Pumpkin Enzyme Mask | Pumpkin enzyme + AHA + aluminum oxide physical exfoliant | Normal, combination & oily skin; dullness, rough texture & occasional intensive exfoliation |
5. Physical Exfoliation
Physical exfoliation uses manual friction to remove surface cells.
Examples can include:
- Sugar or salt scrubs
- Ground particles
- Beads
- Powders
- Brushes
- Exfoliating cloths
The major issue isn’t simply that an exfoliant is physical.
It’s how abrasive it is and how aggressively you use it.
If you’re scrubbing until your skin feels raw or looks red, you’ve gone beyond useful exfoliation.
Should Everyone Avoid Physical Exfoliation?
No.
Some people tolerate gentle physical exfoliation perfectly well.
But if your skin is:
- Sensitive
- Inflamed with acne
- Using retinoids
- Already being exfoliated with acids
Adding abrasive scrubbing may increase irritation.
Physical Exfoliants Worth Considering
| Product | Key Exfoliating Ingredients | Best For |
|---|---|---|
| Tatcha The Rice Polish: Classic | Microcrystalline cellulose + rice powder + papain | Normal, dry & combination skin; dullness, mild roughness & polishing |
| Tatcha The Rice Polish: Deep | Microcrystalline cellulose + rice powder + papain + kaolin | Combination & oily skin; texture, dullness & pore concerns |
| Dermalogica Daily Superfoliant | Microcrystalline cellulose + enzymes / AHAs powder exfoliant | Normal, combination & oily skin; rough texture & more intensive resurfacing |
Note: Some powder exfoliants combine gentle physical particles with enzymes or exfoliating acids, so they may provide more than one type of exfoliation.
6. What About Peeling Gels?
Peeling gels are particularly popular in Asian skincare.
You apply the product, massage it onto the skin, and little rolls or particles begin forming under your fingers.
It can look as though you’re watching large amounts of dead skin roll away.
But those rolls aren’t necessarily made entirely of dead skin.
The product itself can form clumps as you rub it.
That doesn’t mean peeling gels do nothing.
It simply means you shouldn’t interpret every visible roll as proof that you’ve removed a dramatic layer of dead skin.
Peeling Gels Worth Considering
| Product | Key Exfoliating Ingredients | Best For |
|---|---|---|
| Beauty of Joseon Apricot Blossom Peeling Gel | 8% Plant-based cellulose | Gentle exfoliation, dullness & uneven texture |
| COSRX Low pH Goodnight Soft Peeling Gel | 8% cellulose + lactobionic acid (PHA) + papain | Sensitive skin, rough texture & gentle exfoliation |
| Cure Aqua Gel Gentle Exfoliator | Gommage-forming polymer system | Gentle polishing, dullnes & uneven textute |
7. Exfoliating Toners, Pads, Serums and Masks
Exfoliating ingredients can appear in many different product formats.
AHA, BHA and PHA products can be:
- Toners
- Pads
- Serums
- Masks
- Cleansers
- Peels
The format doesn’t determine the strength.
A toner isn’t automatically mild.
A pad isn’t automatically stronger.
A serum isn’t automatically more effective.
Instead, consider:
Which exfoliating ingredient + concentration + formulation + frequency.
This matters because people can unknowingly duplicate exfoliation across several products.
For example, someone might use a:
Salicylic cleanser + AHA toner + exfoliating pad + acid serum + peel mask
That’s not necessarily a “complete exfoliating routine.”
It may simply be too much exfoliation.
Exfoliating Pads Worth Considering
| Product | Key Exfoliating Ingredients | Best For |
|---|---|---|
| First Aid Beauty Brighten & Glow Facial Radiance Pads | Glycolic + lactic acid AHA pads | Normal, dry, combination & sensitive skin; dullness, texture & gentler regular exfoliation |
| Dr. Dennis Gross Alpha Beta Universal Daily Peel | Multi-AHA + salicylic acid two-step peel pads | Normal, combination & oily skin; pores, fine lines, dullness & experienced acid users |
| Medicube Zero Pore Madecassoside Pad (Mild) | PHA toner pads | Dry & sensitive skin; mild texture & gentle exfoliation |
| Glow Recipe Watermelon LHA + AHA Korean Toner Pads | Lactic + mandelic acid (AHAs) + BHA + PHA + LHA + enzymes | Combination & oily/congested skin; pores, breakouts & uneven texture |
| COSRX OneStep Original Blemish Pore Clear Pad | BHA + PHA + LHA toner pads | Oily & blemish-prone skin; excess sebum, pores & rough texture |
At-Home Exfoliating Masks & Peels Worth Considering
| Product | Key Exfoliating Ingredients | Best For |
|---|---|---|
| The Ordinary AHA 30% + BHA 2% Peeling Solution | 30% AHA + 2% BHA rinse-off peel | Experienced acid users; rough texture, dullness & congestion |
| Paula’s Choice Skin Perfecting 25% AHA + 2% BHA Exfoliant Peel | 25% AHA blend + 2% BHA rinse-off peel | Experienced users; stubborn texture, dullness & congestion |
| COSRX The AHA BHA PHA LHA 35% Peel | 35% multi-acid AHA / BHA / PHA / LHA rinse-off peel | Experienced users; rough texture, pores, congestion & dullness |
| Dr.Jart+ Pore Remedy Purifying Mud Face Mask | PHA + green mud + sea salt | Combination & oily skin; excess oil, blackheads & visible pore concerns |
8. Professional Chemical Peels
Professional chemical peels are different from everyday home exfoliating products.
Dermatologists and other appropriately trained professionals may use higher-strength acids to target specific concerns.
Professional peels shouldn’t be treated like stronger versions of a home toner that you can casually recreate.
Concentration, exposure time, skin preparation and aftercare all matter.
If you’re considering a stronger peel — particularly for pigmentation, acne scarring or significant photoaging — professional guidance is safer than experimenting with progressively stronger products at home.
Which Exfoliant Is Best for Your Skin Concern?
Choosing an exfoliant becomes much easier when you start with the problem you’re actually trying to solve.
Which Exfoliant Is Best for Dull Skin?
If dullness and rough surface texture are your primary concerns:
AHA
or possibly
PHA
may be sensible categories to explore.
Glycolic or lactic acid may be useful when the goal is smoother, more radiant-looking skin.
If your skin tends to find AHAs irritating, a PHA may be worth investigating.
Best Exfoliants for Dull Skin
| Product | Type / Form | Key Exfoliating Ingredient |
|---|---|---|
| Anua Rice Enzyme Brightening Cleansing Powder | Powder cleanser | Papain + protease + rice powder + lactic & tartaric acids |
| The Ordinary Glycolic Acid 7% Exfoliating Toner | Exfoliating toner | 7% glycolic acid |
| Sunday Riley Good Genes Lactic Acid Treatment | Serum / treatment | Lactic acid |
| Dermalogica Daily Microfoliant | Enzyme exfoliant / powder | Papain + salicylic acid + rice-based exfoliation |
| DRMTLGY Microdermabrasion Scrub | Physical exfoliant / scrub | Fine pumice |
| Beauty of Joseon Apricot Blossom Peeling Gel | Peeling gel | 8% plant-derived cellulose |
| First Aid Beauty Brighten & Glow Facial Radiance Pads | Exfoliating toner pads | Glycolic + lactic acids |
| Peter Thomas Roth Pumpkin Enzyme Mask | Exfoliating mask | Pumpkin enzymes + AHA + aluminum oxide |
Note: You do not need to use all of these products. Choose one exfoliating product that suits your skin and routine. Using multiple exfoliants together may increase the risk of irritation and over-exfoliation.
Which Exfoliant Is Best for Blackheads?
Salicylic acid/BHA is usually the most relevant category to consider.
Blackheads involve clogged pores.
A pore-targeting exfoliant makes more sense than simply scrubbing the surface harder.
Exfoliating Products Worth Considering for Blackheads
| Product | Type / Form | Key Exfoliating Ingredient |
|---|---|---|
| La Roche-Posay Effaclar Medicated Gel Cleanser | Cleanser | 2% salicylic acid + LHA |
| Paula’s Choice Skin Perfecting 2% BHA Liquid Exfoliant | Leave-on liquid exfoliant | 2% salicylic acid |
| The Ordinary Salicylic Acid 2% Solution | Serum | 2% salicylic acid |
| Dermalogica Daily Microfoliant | Enzyme exfoliant / powder | Papain + salicylic acid + rice-based exfoliation |
| COSRX OneStep Original Blemish Pore Clear Pad | Exfoliating toner pads | BHA + PHA + LHA |
| The Ordinary Salicylic Acid 2% Masque | Exfoliating mask | 2% salicylic acid + charcoal + clay |
Note: You do not need to use all of these products. Choose one exfoliating product that suits your skin and routine. Using multiple exfoliants together may increase the risk of irritation and over-exfoliation.
Which Exfoliant Is Best for Whiteheads and Closed Comedones?
Again:
Salicylic acid/BHA may be useful because of its role in unclogging pores.
But persistent comedonal acne may need more than exfoliation alone.
A dermatologist may recommend other acne treatments depending on the severity.
Exfoliating Products Worth Considering for Whiteheads & Closed Comedones
| Product | Type / Form | Key Exfoliating Ingredient |
|---|---|---|
| CeraVe Acne Control Cleanser | Cleanser | 2% salicylic acid |
| COSRX AHA 7 Whitehead Power Liquid | Leave-on liquid exfoliant | 7% glycolic acid |
| The Ordinary Salicylic Acid 2% Solution | Serum | 2% salicylic acid |
| Dermalogica Daily Microfoliant | Enzyme exfoliant / powder | Papain + salicylic acid + rice-based exfoliation |
| Glow Recipe LHA + AHA Toner Pads | Exfoliating toner pads | Lactic + mandelic acid (АНАs) + ВНА + РНА + LHA + enzymes |
| The Ordinary Salicylic Acid 2% Masque | Exfoliating mask | 2% salicylic acid + charcoal + clay |
Note: You do not need to use all of these products. Choose one exfoliating product that suits your skin and routine. Using multiple exfoliants together may increase the risk of irritation and over-exfoliation.
Which Exfoliant Is Best for Dry Skin?
Dry skin doesn’t automatically need exfoliation.
If the problem is simply dehydration or barrier damage, exfoliating harder may make things worse.
If dry skin also has surface roughness, a carefully chosen:
Lactic acid
or
PHA
may be worth considering.
But hydration and moisturization still need to be addressed.
Exfoliating Products Worth Considering for Dry Skin
| Product | Type / Form | Key Exfoliating Ingredient |
|---|---|---|
| Dermalogica Daily Glycolic Cleanser | Cleanser | Glycolic acid |
| The Ordinary Saccharomyces Ferment 30% Milky Toner | Exfoliating toner | 30% Saccharomyces ferment containing 3% fermented NAG |
| The Ordinary Lactic Acid 5% + HA | Serum | 5% lactic acid |
| Dermalogica Daily Milkfoliant | Enzyme extoliant / powder | Papain + gentle physical exfoliation |
| Beauty of Joseon Apricot Blossom Peeling Gel | Peeling gel | 8% plant-derived cellulose |
| First Aid Beauty Brighten & Glow Facial Radiance Pads | Exfoliating toner pads | Glycolic + lactic acids |
Note: You do not need to use all of these products. Choose one exfoliating product that suits your skin and routine. Using multiple exfoliants together may increase the risk of irritation and over-exfoliation.
Which Exfoliant Is Best for Oily Skin?
For oily skin with congestion:
BHA/salicylic acid
is often a logical choice.
But oily skin that isn’t clogged doesn’t automatically need a BHA.
And oily skin can still become dehydrated or irritated from excessive exfoliation.
Exfoliating Products Worth Considering for Oily Skin
| Product | Type / Form | Key Exfoliating Ingredient |
|---|---|---|
| CeraVe Acne Control Cleanser | Cleanser | 2% salicylic acid |
| COSRX BHA Blackhead Power Liquid | Leave-on liquid exfoliant | Betaine salicylate |
| The Ordinary Salicylic Acid 2% Solution | Serum | 2% salicylic acid |
| Dermalogica Daily Microfoliant | Enzyme exfoliant / powder | Papain + salicylic acid + rice-based exfoliation |
| DRMTLGY Microdermabrasion Scrub | Physical exfoliant / scrub | Fine pumice |
| COSRX Low pH Goodnight Soft Peeling Gel | Peeling gel | 8% cellulose + PHA + papain |
| Glow Recipe LHA + AHA Toner Pads | Exfoliating toner pads | Lactic + mandelic acid (AHAs) + BHA + PHA + LHA + enzymes |
| Beauty of Joseon Red Bean Pore Refreshing Mask | Exfoliating clay mask | Red bean powder + kaolin |
Note: You do not need to use all of these products. Choose one exfoliating product that suits your skin and routine. Using multiple exfoliants together may increase the risk of irritation and over-exfoliation.
Which Exfoliant Is Best for Sensitive Skin?
Sensitive skin requires caution.
The American Academy of Dermatology recommends choosing exfoliation according to skin type and using gentler methods when skin is dry, sensitive or acne-prone.
PHA may be worth considering because there is evidence supporting its tolerability in sensitive skin.
But before adding any exfoliating acid, ask whether your skin actually needs exfoliation at all.
If it is:
- Burning
- Red
- Peeling
- Inflamed
your priority may be barrier recovery rather than exfoliation.
Exfoliating Products Worth Considering for Sensitive Skin
| Product | Type / Form | Key Exfoliating Ingredient |
|---|---|---|
| Aveeno Calm + Restore Nourishing PHA Exfoliator | Exfoliating cleanser | Gluconolactone (PHA) |
| The INKEY List PHA Toner | Exfoliating toner | 3% gluconolactone (PHA) |
| The Ordinary Lactic Acid 5% + HA | Serum | 5% lactic acid |
| Dermalogica Daily Milkfoliant | Enzyme exfoliant / powder | Papain + gentle physical exfoliation |
| COSRX Low pH Goodnight Soft Peeling Gel | Peeling gel | 8% cellulose + PHA + papain |
| First Aid Beauty Brighten & Glow Facial Radiance Pads | Exfoliating toner pads | Glycolic + lactic acids |
Note: You do not need to use all of these products. Choose one exfoliating product that suits your skin and routine. Using multiple exfoliants together may increase the risk of irritation and over-exfoliation.
Which Exfoliant Is Best for Mature Skin?
Mature skin has slightly different priorities. We aren’t just targeting dead-skin buildup; we want exfoliation that can help with dullness, uneven texture, uneven-looking tone and the appearance of fine lines, without unnecessarily stripping skin that may become drier with age.
Exfoliating Products Worth Considering for Mature Skin
| Product | Type / Form | Key Exfoliating Ingredient |
|---|---|---|
| Murad AHA/BHA Exfoliating Cleanser | Exfoliating cleanser | Glycolic + lactic + salicylic acids + jojoba esters |
| Paula’s Choice 6% Mandelic Acid + 2% Lactic Acid Liquid Exfoliant | Leave-on liquid exfoliant | 6% mandelic + 2% lactic acid |
| Sunday Riley Good Genes Lactic Acid Treatment | Serum / treatment | Lactic acid |
| Dermalogica Daily Milkfoliant | Enzyme exfoliant / powder | Papain + gentle physical exfoliation |
| Beauty of Joseon Apricot Blossom Peeling Gel | Peeling gel | 8% plant-derived cellulose |
| First Aid Beauty Brighten & Glow Facial Radiance Pads | Exfoliating toner pads | Glycolic + lactic acids |
Note: You do not need to use all of these products. Choose one exfoliating product that suits your skin and routine. Using multiple exfoliants together may increase the risk of irritation and over-exfoliation.
AHA vs BHA vs PHA: The Simple Version
Here’s the easiest way to think about the three.
Consider AHA when your main concern is:
Dullness → Surface roughness → Uneven-looking tone
Consider BHA when your main concern is:
Blackheads → Whiteheads → Clogged pores
Consider PHA when you want:
Mild surface exfoliation
but your skin tends to be:
Dry or sensitive
This isn’t an absolute rule.
But it’s a useful starting framework.
For a detailed comparison of the first two categories, see our AHA vs BHA guide.
Can You Use AHA, BHA and PHA Together?
You can find professionally formulated products containing more than one exfoliating acid.
That doesn’t mean you need:
AHA toner + BHA serum + PHA pad
in the same routine.
Ask:
What additional problem is each product solving?
If the answer is:
“They’re all exfoliating.”
you may simply be duplicating one job three times.
For beginners, one exfoliating product at a time is much easier to evaluate.
Can You Exfoliate While Using Retinol or Retinal?
Possibly — but caution matters.
Retinoids can already cause:
- Dryness
- Peeling
- Irritation
Adding exfoliation can increase the overall irritation load.
If you’re new to a retinoid, it can be sensible to establish tolerance before adding stronger exfoliating products.
For example, rather than stacking everything into one evening, someone might use:
Night 1 → Retinoid
Night 2 → Basic moisturizer routine
Night 3 → Exfoliant, if needed
The exact routine should still depend on the products you’re using and how well your skin tolerates them.

Exfoliation and Acne Treatments
Be particularly cautious with exfoliation if you’re using prescription or strong acne treatments.
The American Academy of Dermatology specifically advises against certain exfoliating methods while taking isotretinoin because the skin may be more easily irritated.
If you’re under dermatologic treatment, follow your dermatologist’s instructions rather than adding acids based on social-media routines.
How Often Should You Exfoliate?
There is no universal schedule.
Not:
“Everyone should exfoliate twice a week.”
And not:
“Daily exfoliation is always better.”
Frequency depends on:
- Exfoliant type
- Concentration
- Product format
- Formulation
- Your other active ingredients
- Your skin’s tolerance
The American Academy of Dermatology notes that more aggressive exfoliation generally needs to be performed less frequently, while gentler methods may be used more often depending on the skin and method.
Start conservatively and pay attention to how your skin responds.
What Does Over-Exfoliated Skin Look Like?
Possible warning signs include:
- Burning
- Unusual tightness
- Redness
- Stinging
- Excessive peeling
- Increased sensitivity
- Sudden reactions to products that were previously comfortable
- Shiny but irritated-looking skin
- Breakouts associated with irritation
The solution usually isn’t:
Add another exfoliating acid.
It may be:
Pause exfoliation → simplify the routine → moisturize → allow the skin barrier to recover.
Can Exfoliation Damage the Skin Barrier?
Yes, if it’s too aggressive.
The outermost layer of the skin plays an important role in retaining water and protecting against environmental stressors.
Over-exfoliating can disrupt that balance.
That’s why smoother skin should never come at the cost of:
Burning, peeling or chronic irritation.
Does Tingling Mean an Acid Is Working?
Not necessarily.
Mild, temporary sensations can occur with certain products.
But:
Burning is not proof of effectiveness.
If a product causes significant or persistent discomfort, wash it off and reassess.
Your exfoliant doesn’t need to hurt to work.
Exfoliation and Sunscreen
Sun protection matters for everyone.
But it deserves particular attention when using AHAs.
The FDA warns that AHAs may increase sun sensitivity and the possibility of sunburn.
A good exfoliating routine therefore includes:
Appropriate exfoliation + daily broad-spectrum sunscreen
not exfoliation alone.
Do You Even Need to Exfoliate?
Not necessarily.
Your skin naturally sheds cells.
Some people may benefit from supplemental exfoliation because of:
- Dullness
- Rough texture
- Clogged pores
Others may have perfectly healthy skin without using an exfoliating acid at all.
If your skin is:
- Smooth
- Comfortable
- Clear enough for you
- Not congested
you don’t need an exfoliant simply because skincare culture tells you everyone must have one.
8 Common Exfoliation Mistakes
1. Using Multiple Exfoliants Without Realizing It
Read your ingredient lists. Your cleanser, toner, pads and serum may all contain exfoliating ingredients.
2. Choosing the Strongest Acid Possible
Higher strength doesn’t automatically create a better routine.
3. Exfoliating Every Day Immediately
Give your skin time to adjust before increasing frequency.
4. Scrubbing After Using Acids
This can unnecessarily increase irritation.
5. Using Acids on Already Irritated Skin
Give your skin barrier time to recover.
6. Assuming Peeling Means Progress
Excessive peeling isn’t the goal.
7. Ignoring Sunscreen
This is particularly important when using AHAs.
8. Treating Every Bump as Something to Exfoliate
Not every type of skin texture is caused by accumulated dead skin cells.
The Dew & Detail Exfoliation Method
Before choosing another exfoliant, use this four-step approach.
Step 1 — Identify the Concern
Is it:
Blackheads?
Roughness?
Whiteheads?
Flaking?
Don’t just say “texture.”
Work out what you’re actually trying to improve.
Step 2 — Choose the Category
Surface dullness → Consider AHA
Congested pores → Consider BHA
Gentler surface exfoliation → Consider PHA
Step 3 — Check the Rest of Your Routine
Are you already using:
- Acids
- Retinoids
- Acne treatments
- Exfoliating masks
If yes, you may need less — not more.
Step 4 — Start Conservatively
Give your skin time to respond before increasing frequency.
Concern → Exfoliant → Tolerance → Consistency
That’s a much better approach than:
Trend → Strongest acid → Daily use → Irritation
Exfoliating Ingredients Guide: Frequently Asked Questions
Is AHA Better Than BHA?
Neither is universally better.
AHAs are particularly relevant for surface texture and dullness, while salicylic acid/BHA is particularly useful when clogged pores are the main concern.
Is PHA Better for Sensitive Skin?
PHA has evidence suggesting good tolerability and additional humectant properties, making it an interesting option when sensitive skin needs gentle exfoliation.
That doesn’t mean every sensitive skin type will tolerate every PHA product.
Can I Use AHA and BHA Together?
Yes. Some formulations contain both.
But you don’t need to layer multiple separate acids simply because they perform somewhat different jobs.
Is Glycolic Acid an AHA?
Yes.
Is Lactic Acid an AHA?
Yes.
Is Salicylic Acid a BHA?
Yes. It is the BHA most commonly used in cosmetic skincare.
Is Gluconolactone a PHA?
Yes.
Gluconolactone is one of the best-known polyhydroxy acids used in skincare.
Can I Exfoliate Every Day?
Possibly with some gentle formulations, but daily exfoliation isn’t necessary for everyone.
Frequency should depend on the product, your overall routine and your skin’s tolerance.
Should I Exfoliate Before Retinol?
You don’t need to exfoliate simply to “prepare” your skin for retinol.
Using both too aggressively may increase irritation.
Can Exfoliation Shrink Pores?
No exfoliant permanently changes the anatomical size of your pores.
Keeping pores clearer may make them appear less noticeable.
What Is the Gentlest Exfoliating Acid?
There isn’t one universal answer.
However, PHAs such as gluconolactone may be worth exploring when tolerability is a priority.
The Dew & Detail Takeaway
Exfoliation isn’t about removing as much skin as possible.
It’s about choosing the right tool for the right concern.
AHA works primarily at the surface and can help improve the appearance of dullness, roughness and uneven-looking tone.
BHA, usually salicylic acid, is particularly relevant for blackheads, whiteheads and clogged pores.
PHA provides another surface-exfoliating option and may be especially interesting for skin that finds traditional acids difficult to tolerate.
Enzyme and physical exfoliation can also have a place — but neither needs to be aggressive.
And remember: not everyone needs to exfoliate.
The most important rule?
Your skin should look better because you exfoliate — not spend the rest of the week recovering from it.
