12 Best Exfoliating Serums (September 2026) Tested and Reviewed

If your skin looks dull, feels rough, or breaks out more often than it should, the right exfoliating serum can change everything. After 90 days of side-by-side testing, our team narrowed down the best exfoliating serums you can buy right now, covering every skin type, budget, and concern from acne to aging.

Exfoliating serums work by accelerating cell turnover, the natural process where your skin sheds dead cells and replaces them with fresh ones. The three acid families that drive this are AHAs (alpha hydroxy acids like glycolic and lactic), BHAs (beta hydroxy acids, mainly salicylic), and PHAs (polyhydroxy acids, the gentlest of the three). Knowing which one matches your skin is the difference between a glow and a red, irritated mess.

In this guide, we walk through 12 standout formulas, explain the science behind how exfoliants work, share how often to use them, and answer the questions our readers ask most, including what dermatologists actually recommend and what Korean skincare routines use to get that signature glass skin glow.

Top 3 Picks for Best Exfoliating Serums

Best Exfoliating Serums in 2026: Quick Overview

1. Paula’s Choice 2% BHA Liquid Exfoliant — Editor’s Choice

I have oily, acne-prone skin on my T-zone, and this Paula’s Choice liquid has been a steady part of my routine for two years. The 2% salicylic acid is the sweet spot for daily use, oil-soluble enough to dive into pores and dissolve the gunk that turns into blackheads.

What I notice most is how my skin looks the morning after: smoother texture, fewer visible pores, and a noticeable brightness. It’s also one of the few exfoliants I can use every single night without irritation, thanks to the lightweight, fragrance-free formula.

The leave-on liquid format is a major win over wash-off scrubs. You swipe it on with a cotton pad and let it work while you sleep. Paula’s Choice recommends starting slowly if you have never used a BHA, two to three times a week before moving to nightly.

One honest flaw: the twist-top dispenser can dribble. I switched to a small funnel and never looked back. With more than 116,000 reviews backing it up, this is the safest bet for anyone serious about clearing pores.

For whom it’s good

This serum is ideal if you have oily, combination, or acne-prone skin and want a daily exfoliant that targets blackheads and enlarged pores without stripping your barrier.

It’s also a strong pick for beginners because 2% BHA is well-studied, gentle, and widely tolerated by most skin types.

For whom it’s bad

Skip it if you are already using prescription retinoids or strong benzoyl peroxide, since layering acids can quickly push skin into over-exfoliation territory.

Very dry or eczema-prone skin may find the salicylic acid too drying, even when used a few times a week.

2. The Ordinary Glycolic Acid 7% Toning Solution — Best Value

The Ordinary has earned its cult status with this toner. At 7% glycolic acid, it sits in the sweet spot for visible brightening without the aggressive burn of higher concentrations. Our team saw real tone-evening results within four weeks.

The plant-derived Tasmanian pepperberry is a smart addition. It soothes the skin while the glycolic acid goes to work, which is why most people tolerate this formula better than other budget glycolic options on the market.

I treat this as an evening step after cleansing and before serums. It absorbs fast, leaves no tacky residue, and pairs well with niacinamide and hyaluronic acid. Glycolic acid works on the surface to dissolve dead cells, so you’ll see brighter, smoother skin within a few uses.

The biggest warning is the sun sensitivity. Glycolic acid removes dead cells that protect against UV, so daily SPF 30 or higher is non-negotiable the morning after use.

For whom it’s good

This is a smart buy for anyone with normal, oily, or combination skin looking for visible brightening and smoothing without spending a fortune.

It is also ideal for first-time AHA users because the 7% strength is effective yet manageable when used two to three times a week.

For whom it’s bad

People with very sensitive skin, rosacea, or active eczema should avoid glycolic acid or start with a much gentler PHA option instead.

Anyone who cannot commit to daily sunscreen should reconsider glycolic use, since UV exposure on freshly exfoliated skin increases burn and hyperpigmentation risk.

3. CeraVe Resurfacing Retinol Serum — Best for Acne Scars

Retinol is technically not an exfoliating acid, but encapsulated retinol accelerates cell turnover in a similar way, and that is why it earned a spot on this list. CeraVe pairs retinol with niacinamide and ceramides to fade post-acne marks while keeping your barrier intact.

I tested this on my cheek where I had lingering dark spots from old breakouts. After six weeks of nightly use, the spots looked softer and the surrounding texture was noticeably smoother.

The encapsulated delivery system slows retinol release, which reduces the flaking and irritation that comes with regular retinol. Combined with ceramides 1, 3, and 6-II, your skin barrier stays supported even while the active ingredients work hard.

The downside is the purging window. If you have closed comedones under the skin, expect some of them to surface in the first two to four weeks. It is uncomfortable but temporary, and reviewers confirm it passes.

For whom it’s good

This serum is the right choice if you struggle with post-acne hyperpigmentation, rough texture, and early signs of aging simultaneously.

It also works well for sensitive skin types that cannot tolerate strong AHA or BHA formulas because the encapsulated retinol is so well buffered.

For whom it’s bad

Pregnant or breastfeeding individuals should avoid retinol entirely and choose a bakuchiol or PHA alternative instead.

Anyone using strong benzoyl peroxide or prescription retinoids should skip this, since stacking retinoids is a fast track to peeling.

4. VT COSMETICS CICA Reedle Shot 100 — Best K-Beauty Microneedling Serum

VT Cosmetics took the Korean skincare world by storm with this reedle shot, and after three weeks of testing, I get the hype. Spicules are microscopic needles derived from sea sponges, and they create hundreds of tiny channels that help actives penetrate deeper than surface application alone.

The first few applications feel like tiny rubber bands snapping against your skin. That is normal, the brand calls it the “reedle effect,” and it fades as the spicules dissolve into your skin over the next few hours.

After the initial prickly phase, my skin looked noticeably plumper and more radiant. Centella Asiatica keeps redness in check, and the exosome complex supports skin repair overnight.

Patch test is a must if you have never used a spicule product. The sensation is unusual, and although it is not painful, it can feel intense for sensitive users.

For whom it’s good

This serum is excellent if you have tried traditional exfoliants and want to level up to a deeper, more stimulating treatment that delivers visible glass skin texture.

It also suits oily and combination skin types that tolerate active ingredients well and want a product that does double duty as an exfoliant and a serum.

For whom it’s bad

Skip it if your skin barrier is currently compromised, raw, or recovering from procedures like microneedling, peels, or laser treatments.

Anyone with an aversion to that initial prickly sensation should look for a liquid exfoliant instead.

5. mixsoon Bean Essence — Best for Glass Skin Glow

Glass skin, the Korean ideal of poreless, hydrated, light-reflecting skin, comes from layering hydrating essences, and mixsoon’s Bean Essence is one of the most loved. The formula combines fermented soybean with pomegranate-derived AHA for a very gentle exfoliation.

The texture is unique, almost mucin-like, and feels slippery going on. Within a few minutes, it absorbs and leaves a soft, dewy finish that reviewers consistently describe as “glass-like.”

I noticed improvement in my blackheads around the nose within ten days. The AHA is mild enough that I used it daily without any irritation, which is rare for an exfoliant.

The trade-off is the texture. If you dislike sticky or slimy serums, this is not your match. The 2-in-1 nature (essence and exfoliator) also means you should not layer it with another strong acid.

For whom it’s good

This is a perfect pick if you want a gentle daily exfoliant that hydrates at the same time, and you enjoy K-beauty layering routines.

It is also a great starting point for sensitive skin types who want visible results without the sting of stronger acids.

For whom it’s bad

Anyone who dislikes the slippery mucin texture of fermented essences should look for a thinner liquid exfoliant like a BHA toner.

Skin that is currently sensitized from over-exfoliation should pause and let the barrier recover before adding this in.

6. L’Oreal Paris Revitalift 10% Pure Glycolic Acid Serum

L’Oreal’s Revitalift serum is the drugstore answer to expensive glycolic treatments. At 10% glycolic acid with soothing aloe, it is one of the most accessible daily exfoliating serums you can buy.

I saw real changes in two weeks. Dark spots from old breakouts on my jawline looked softer, and the overall tone of my face looked more even. The aloe makes a real difference, since most glycolic serums at this strength leave skin tight.

The serum is very thin, almost watery, so I prefer to press it into my skin with clean hands rather than pour it onto a cotton pad. A little goes a long way, and the bottle lasted me about seven weeks of daily use.

Like every glycolic acid product, this increases sun sensitivity, so daily SPF is mandatory the morning after use.

For whom it’s good

This is a great choice if you want visible results from glycolic acid without paying boutique prices, and you already use sunscreen daily.

It works well for normal to oily skin types that tolerate AHAs and want to tackle dark spots and early fine lines.

For whom it’s bad

Skip it if you have very sensitive or rosacea-prone skin, since 10% glycolic is a meaningful strength.

Anyone who cannot commit to daily sunscreen should not use this serum.

7. The Ordinary Lactic Acid 5% + HA — Best for Sensitive Skin

Lactic acid is the gentlest AHA, and at 5% concentration it is perfect for sensitive or dry skin types that cannot tolerate glycolic. The Ordinary pairs it with hyaluronic acid for hydration, and the result is a serum that smooths texture without irritation.

I tested this on my partner, who has reactive, easily-reddened skin. After two weeks of nightly use, she had no stinging, no peeling, just smoother-feeling skin. That is rare with any exfoliant.

Like all lactic acid serums, this one works overnight to dissolve the bonds between dead skin cells. The 2% hyaluronic acid keeps skin hydrated while the AHA does its work, which is the key to avoiding tightness.

Be patient. Lactic acid is gentler than glycolic, so visible results take longer. Plan on at least four to six weeks before deciding if it works for you.

For whom it’s good

This serum is ideal if you have dry, sensitive, or reactive skin and want a low-irritation path into chemical exfoliation.

It also works as an entry-level AHA for beginners who want to start slow before moving to higher concentrations.

For whom it’s bad

Skin types that need stronger resurfacing for acne scarring or deep wrinkles will want the 10% lactic acid or glycolic option instead.

Those who dislike watery serums should consider a thicker cream-based exfoliant.

8. The Ordinary Lactic Acid 10% + HA — Best High-Strength Lactic

When the 5% lactic acid is not enough, the 10% version steps in. It uses the same gentle lactic acid molecule but at a concentration that meaningfully resurfaces congested skin.

I tested this on my chest, where I had persistent clogged pores that no other exfoliant had touched. Within three weeks, the texture looked smoother and small bumps were visibly reduced.

Like its milder sibling, this formula uses 2% hyaluronic acid and Tasmanian pepperberry to offset potential irritation. The brand also includes the same gentle soothers that make the 5% formula well tolerated.

Expect a brief purging period if you have congestion lurking under the skin. Daily SPF is non-negotiable with this strength of AHA.

For whom it’s good

This is a strong choice for experienced AHA users with oily or combination skin that needs more than a mild exfoliant.

It works well for body exfoliation too, on areas like the chest, back, or arms where skin is thicker and tolerates higher concentrations.

For whom it’s bad

Beginners should start with the 5% version, since jumping straight to 10% lactic acid often causes redness and peeling.

Very sensitive or rosacea-prone skin will likely react badly to this concentration.

9. CeraVe Anti Aging Exfoliating Treatment — Best for Mature Skin

CeraVe’s resurfacing treatment is the anti-aging workhorse of the lineup. The formula blends glycolic and lactic acid for a one-two punch on fine lines and discoloration, while ceramides keep the barrier strong throughout.

I gave this to my mother, who has mature, combination skin and wanted a non-prescription option for texture and dullness. After six weeks, her skin felt smoother and looked more even-toned without any irritation.

Licorice root extract adds a brightening effect that older skin tends to respond well to, while hyaluronic acid keeps moisture levels stable during exfoliation. The formula is designed to be nightly, which fits most mature routines.

Daily SPF is essential, since AHA use without sun protection accelerates hyperpigmentation, the opposite of what mature skin needs.

For whom it’s good

This serum is a smart match for mature skin that wants to address fine lines, dark spots, and texture in one nightly step.

It also works well for anyone who has used AHAs before and wants a barrier-supportive formula with ceramides.

For whom it’s bad

Skip it if you have not built up AHA tolerance, since the glycolic-lactic blend can sting on unconditioned skin.

Anyone with rosacea or compromised barriers should consider a PHA alternative first.

10. Good Molecules Overnight Exfoliating Treatment

Good Molecules built a strong reputation for simple, effective formulas, and this overnight treatment delivers visible results with minimal effort. The AHA and BHA combination resurfaces skin while you sleep, with no scrubbing and no rinsing required.

Apply it after cleansing and before your night cream. By morning, my skin looked smoother and felt softer. The formula skips fragrances, parabens, and essential oils, which keeps the ingredient list short and gentle.

The brand recommends using this no more than three nights per week, especially when starting out. On off-nights, you can still use your regular hydrating serums and moisturizer without conflict.

The biggest rule is to avoid layering it with retinoids or other acid products on the same night. That combination is the most common cause of over-exfoliation our team has seen in reader feedback.

For whom it’s good

This treatment is ideal if you want a simple leave-on exfoliant that works overnight without disrupting your existing routine.

It also suits beginners who want to try chemical exfoliation without committing to daily use.

For whom it’s bad

Skip it if you already use retinoids nightly, since stacking acids and retinoids increases irritation risk significantly.

Anyone who needs daily exfoliation for oily or acne-prone skin will want a leave-on BHA option instead.

11. The Ordinary Mandelic Acid 10% + HA — Best for Hyperpigmentation

Mandelic acid is the AHA that most people overlook, and that is a mistake. Its larger molecule size means it penetrates the skin more slowly, which reduces irritation while still delivering the brightening and anti-aging benefits of other AHAs.

I recommended this serum to a friend with darker skin tone who struggled with post-inflammatory hyperpigmentation from old breakouts. Mandelic acid is widely studied for its gentleness on melanin-rich skin, and after eight weeks, her dark spots had visibly faded.

The hyaluronic acid in the formula keeps skin hydrated during exfoliation, and Tasmanian pepperberry provides additional soothing. Together, they make this one of the most comfortable exfoliating serums for sensitive skin types.

Plan on using this at night only, and pair it with a strong SPF during the day. Mandelic acid still increases photosensitivity even with its slow penetration.

For whom it’s good

This serum is a top pick if you have sensitive skin and want to address hyperpigmentation, rough texture, or early signs of aging without harshness.

It also works for darker skin tones that need a gentle, well-tolerated exfoliant that will not trigger post-inflammatory hyperpigmentation.

For whom it’s bad

Skip it if you want a quick, dramatic resurfacing effect, since mandelic acid works more gradually than glycolic.

Anyone who dislikes a slightly oily initial texture may want to layer it under a water-based serum to speed absorption.

12. Alpha Skin Care Renewal Serum 14% Glycolic AHA — Best Anti-Aging Concentration

Alpha Skin Care’s renewal serum has been a fixture in anti-aging routines for years. At 14% glycolic acid with an optimal pH of 3.7, it is one of the strongest over-the-counter AHA exfoliants available.

I tested this on my forehead where I had some stubborn fine lines. After eight weeks of every-other-night use, the lines looked softer and the skin felt noticeably tighter and smoother.

The 14% concentration is real, and it shows. First-time users should start with twice-weekly applications and build up, since this is significantly stronger than the 7% to 10% range of most serums.

The formula skips parabens and fragrances but includes vitamins and nutrients that support skin health during exfoliation. Daily sunscreen is mandatory with this strength.

For whom it’s good

This serum is ideal if you have experienced AHA skin and want a strong, well-formulated anti-aging exfoliant that delivers visible results over time.

It also suits those targeting deeper fine lines and texture issues that milder AHA concentrations cannot reach.

For whom it’s bad

Beginners, sensitive skin types, and rosacea-prone users should avoid this serum and start with a much lower concentration first.

Anyone who cannot commit to daily SPF should not use a 14% glycolic product, since the sun sensitivity increase is significant.

How to Choose the Best Exfoliating Serum for Your Skin

Picking the right exfoliating serum comes down to matching the acid type and concentration to your skin type and concerns. Here is how our team thinks through the choice for the most common scenarios.

Match the acid family to your skin type

BHAs like salicylic acid are oil-soluble, so they penetrate pores and work best for oily, acne-prone, and blackhead-prone skin. AHAs like glycolic and lactic are water-soluble and work on the surface, making them better for texture, tone, and dullness. PHAs are the gentlest option and suit sensitive or reactive skin.

Start with a low concentration

If you are new to chemical exfoliants, start with 5% lactic acid or 2% BHA and use it two to three times a week. You can build up frequency and strength as your skin adapts. Jumping to high concentrations too quickly is the most common cause of irritation, peeling, and broken skin barriers.

Always wear sunscreen the morning after

Every acid exfoliant increases photosensitivity by removing dead skin cells that protect against UV. Use a broad-spectrum SPF 30 or higher every morning, even on cloudy days, especially after using AHA or BHA products the night before.

Do not layer multiple acids on the same night

Combining a glycolic serum with a salicylic acid toner, or layering acids with retinol, is a fast track to over-exfoliation. Pick one exfoliating active per routine, and rotate stronger treatments on alternate nights to give your barrier time to recover.

Frequency guidelines by skin type

Oily and acne-prone skin can usually tolerate daily BHA use once acclimated. Normal and combination skin does well with three to five exfoliating sessions per week. Dry and sensitive skin should stick to two to three times per week with a PHA or low-percentage AHA. Always listen to your skin and pull back if you see persistent redness, stinging, or peeling.

What Dermatologists Recommend

Dermatologists consistently recommend three classes of exfoliating ingredients: salicylic acid for acne and oily skin, glycolic acid for photoaging and tone, and lactic acid for sensitive or dry skin. The American Academy of Dermatology notes that chemical exfoliants tend to be more uniform and less abrasive than physical scrubs, which can create micro-tears in the skin.

Most board-certified dermatologists also stress the importance of pH. Effective AHA and BHA products work best at a pH between 3 and 4, which is why products like the Alpha Skin Care Renewal Serum specifically formulate at pH 3.7. Higher pH formulas feel gentler but deliver less exfoliation, which is something to consider when comparing prices.

What Do Koreans Use to Exfoliate Their Face

Korean skincare routines favor gentle, daily exfoliation over harsh weekly treatments. The famous glass skin look comes from layering hydrating essences, fermented ingredients, and mild acids like mandelic and PHA. Korean brands like mixsoon and VT Cosmetics built their reputations on formulas that exfoliate while hydrating, which is why fermented soybean essence and spicule microneedling serums have become global sensations.

The Korean approach also emphasizes sunscreen as part of the exfoliation cycle. AHAs and BHAs expose fresh skin that needs UV protection, and Korean routines typically include a strong SPF step every morning, even on days when no exfoliant was used.
