Key Takeaways

• Glycolic Acid appears in seven of the nine formulas here, while Lactic and Mandelic Acids show up in formulas their brands describe as gentle, so the acid type may matter as much as the percentage.

• Where a brand states it, the AHA percentage on this list runs from 5% to 12%, and three entries, both pads and the ALASTIN polish, don’t state one at all.

• FDA recommends a Sunburn Alert on cosmetics that contain an AHA, so sunscreen and limited sun exposure are especially important while you use any of these and for a week afterward.

• Starting a few times a week, as several brands here suggest, may help keep visible dryness and redness to a minimum while your skin adjusts.

• A leave-on gel, toner, or serum tends to suit a regular evening step, while a pad or a rinse-off polish may be the easier fit for a short routine.

AHA Exfoliants for Rough-Looking Texture and Dullness

Alpha Hydroxy Acids (AHAs) are the exfoliants most people reach for when skin starts to look rough, uneven, or dull. FDA’s page on AHAs explains that products containing them cause exfoliation, the shedding of the skin at the surface, and that how much depends on the type and concentration of the AHA, its pH, and the other ingredients in the formula. Glycolic and Lactic Acids are the most common in cosmetics, per the same page, and Citric Acid appears on its list too. Mandelic Acid is another AHA you’ll see on labels.

So the percentage on the front of the bottle is only part of the answer. Acid type, format, pH where a brand publishes it, and how often the brand suggests using the product all shape how an exfoliant is likely to feel, which is why a lower-percentage toner can be the easier habit to keep. For Glycolic and Lactic Acids, FDA also summarizes the Cosmetic Ingredient Review (CIR) Expert Panel’s safety conclusion for consumer products: an AHA concentration of 10% or less, a final pH of 3.5 or greater, and either sun protection built into the formula or directions to use daily sun protection.

Below, nine leave-on, pad, and rinse-off AHA exfoliants are compared on five things: the AHA type and percentage, the format, the published pH, what the INCI shows about fragrance and alcohol, and the price for the size.

At a Glance

• Paula’s Choice Skin Perfecting 8% AHA Gel Exfoliant: a short, fragrance-free Glycolic Acid gel for a regular leave-on step.

• The INKEY List Glycolic Acid Toner: the lowest price for a stated 10% Glycolic Acid.

• Naturium Mandelic Topical Acid 12%: a Mandelic Acid serum for anyone easing into acids.

• Neostrata Glycolic Renewal Smoothing Cream: an AHA blend in a face moisturizer.

• Biossance Squalane + 10% Lactic Acid Resurfacing Serum: Lactic Acid and Squalane in a creamy evening serum.

• Pixi Glow Tonic: a 5% Glycolic Acid toner in the largest bottle on the list.

• StriVectin Daily Reveal Exfoliating Pads: a once-daily pad that combines several acids.

• First Aid Beauty Facial Radiance Pads With Glycolic + Lactic Acids: pre-soaked pads for a quick, measured swipe.

• ALASTIN ReSURFACE Skin Polish: Glycolic Acid in a rinse-off polish with a volcanic mineral.

How We Compared These Products

The comparison draws on each brand’s product page and published ingredient list as of September 2026, not on hands-on use. Five criteria shaped the order.

• AHA type and percentage: Glycolic, Lactic, and Mandelic Acids are different ingredients, and a stated percentage tells you how much of one a brand chose to include. Where no percentage is stated, we note where the acid sits in the INCI instead.

• Format: A leave-on gel, toner, serum, or cream stays on skin until your next cleanse, a pad gives a set amount per swipe, and a polish is rinsed off after about 30 seconds, which tends to change how the same acid feels.

• Published pH: FDA lists pH among the factors that shape how much an AHA exfoliates, and the CIR conclusion it summarizes sets a floor of 3.5 for consumer products. Only two brands here publish a pH.

• Fragrance and alcohol in the INCI: We read each full ingredient list for Fragrance/Parfum, essential oils, and Alcohol, since those tend to matter most to sensitive or drier-feeling skin.

• Price for the size: Sizes run from 1 fl oz to 250 ml, and two entries are sold by the pad, so the sticker price only tells part of the story.

AHA Exfoliants Compared

1. Paula’s Choice Skin Perfecting 8% AHA Gel Exfoliant

This leave-on gel is built around 8% Glycolic Acid, with Chamomile, Aloe, Sodium Hyaluronate, and Panthenol listed alongside it. The brand gives a pH range of 3.5 to 3.9 and suggests a dime-sized amount over the face after cleansing, with no rinsing. The full ingredient list runs to 15 items and shows no Fragrance/Parfum. If you want one plain, regular AHA step for rough-looking texture and the look of dullness, it’s the most straightforward formula here.

Best for: A regular leave-on Glycolic Acid step for visibly smoother texture and brighter-looking skin.

Key ingredients: Glycolic Acid (8%), Chamomile, Aloe, Sodium Hyaluronate, Panthenol.

Price: $37 for 3.3 fl oz.

Worth knowing: The directions allow use up to twice daily. If your skin is new to acids, starting a few evenings a week, as other brands on this list suggest, may feel more comfortable.

2. The INKEY List Glycolic Acid Toner

Here, 10% Glycolic Acid is paired with Witch Hazel Water in a toner you sweep over the face and neck on a cotton pad and leave on. The brand lists a pH of 3.6 to 4.0, which sits inside the 10%-or-less, pH-3.5-or-greater range in the CIR conclusion FDA summarizes. Its FAQ suggests starting one to three times a week in the evening and building up as your skin adjusts. At $18 for 100 ml, it’s the lowest price on the list for a stated 10% Glycolic Acid.

Best for: A budget toner-format AHA a few evenings a week.

Key ingredients: Glycolic Acid (10%), Witch Hazel Water, Betaine.

Price: $18 for 100 ml.

Worth knowing: Alcohol appears in the INCI, and the brand points sensitive skin toward its PHA Toner instead.

3. Naturium Mandelic Topical Acid 12%

Mandelic Acid leads the formula, with Niacinamide, Sodium Hyaluronate, and fruit and plant extracts, such as Bilberry, Sugar Cane, Orange, and Lemon. Naturium describes it as a gentle exfoliant for sensitive skin and for anyone sensitive to BHAs, and labels it Fragrance Free. The directions suggest a few times a week to start, increasing as your skin builds tolerance, and following with a moisturizer. It has the highest stated percentage on this list, and at $20 for 30 ml it’s also one of the least expensive.

Best for: Easing into acids with a Mandelic Acid serum for smoother-looking texture.

Key ingredients: Mandelic Acid (12%), Niacinamide, Sodium Hyaluronate, Bilberry Fruit/Leaf Extract.

Price: $20 for 30 ml.

Worth knowing: The CIR conclusion FDA summarizes covers Glycolic and Lactic Acids, so this 12% Mandelic Acid isn’t directly comparable with the 10% Glycolic and Lactic entries.

4. Neostrata Glycolic Renewal Smoothing Cream

A 10% AHA blend of Glycolic and Citric Acids goes into a lightweight face moisturizer, with Shea Butter and Glycerin in the base. That makes it the entry here that folds the exfoliating step into the moisturizing step. Neostrata suggests that first-time Glycolic Acid users apply it every other day and work up to twice daily over 1 to 2 weeks, and its product page carries the Sunburn Alert. The ingredient list shows no fragrance.

Best for: An AHA in your moisturizer step, for visibly smoother texture.

Key ingredients: Glycolic Acid and Citric Acid (10% AHA blend), Shea Butter, Glycerin.

Price: $55 for 1.4 oz (40 g).

Worth knowing: It’s a small jar for a face-and-neck moisturizer, and the INCI includes Methylparaben, which matters if you avoid parabens.

5. Biossance Squalane + 10% Lactic Acid Resurfacing Serum

Lactic Acid at 10% and Squalane anchor a creamy serum you massage onto the face and neck, two to three pumps at a time. Lactic Acid is one of the two AHAs FDA names as most common in cosmetics, and here it sits third in the INCI, after Water and Caprylic/Capric Triglyceride. Biossance says the serum can be used daily without rinsing, and it suggests alternating days if you also use a conventional Retinol. The brand’s FAQ refers to it as a night serum, so it fits most easily into an evening routine.

Best for: A Lactic Acid serum step in the evening, for softer-feeling, smoother-looking skin.

Key ingredients: Lactic Acid (10%), Squalane, Glycerin, Lespedeza Capitata Leaf/Stem Extract.

Price: $68 for 30 ml.

Worth knowing: The INCI lists Lavender Oil and Linalool, which matters if you avoid essential oils or fragrance ingredients.

6. Pixi Glow Tonic

Aloe and Ginseng join 5% Glycolic Acid in this toner, which goes on with a cotton pad across the face and neck, morning, evening, or both. It has the lowest stated percentage on the list and, at 250 ml, the largest bottle, which keeps its cost per milliliter low. Pixi calls the formula alcohol-free and suggests that sensitive skin begin two to three times a week before using it more often. If you’re easing into an AHA habit, a low-percentage toner like this one tends to be a comfortable starting point.

Best for: A low-percentage Glycolic Acid start for brighter-looking skin.

Key ingredients: Glycolic Acid (5%), Aloe, Panax Ginseng Root Extract, Panthenol.

Price: $29 for 250 ml (8.5 fl oz).

Worth knowing: Parfum/Fragrance appears in the INCI, along with fragrance components, such as Linalool and Limonene.

7. StriVectin Daily Reveal Exfoliating Pads

Each pad comes soaked in a multi-acid solution, with Glycolic Acid third in the INCI and Azelaic Acid, Tranexamic Acid, Capryloyl Salicylic Acid, and Gluconolactone, a Polyhydroxy Acid (PHA), further down. The brand pairs that with what it calls micro-peel fibers for physical exfoliation, and it directs one pad once daily, morning or evening, before serum and moisturizer. A jar holds 60 pads, which StriVectin frames as 2 months of use, and the product page carries the Sunburn Alert.

Best for: A once-daily pad that combines an AHA, a BHA, and a PHA in one swipe.

Key ingredients: Glycolic Acid, Azelaic Acid, Tranexamic Acid, Capryloyl Salicylic Acid, Gluconolactone.

Price: $49 for 60 pads.

Worth knowing: StriVectin doesn’t state an acid percentage, and the INCI includes Alcohol Denat., Grapefruit Peel Oil, and Limonene.

8. First Aid Beauty Facial Radiance Pads With Glycolic + Lactic Acids

These pre-soaked pads pair Lactic and Glycolic Acids with Aloe, Cucumber Fruit Water, and Hyaluronic Acid. The brand suggests swiping one across the face, neck, and décolleté once or twice daily. Lemon Peel and Mandarin Orange Fruit Extracts appear in the INCI, and Fragrance/Parfum doesn’t. The pads come in 28, 60, and 90 counts, which makes the smallest jar an easy way to try a daily AHA habit before committing to a larger one.

Best for: A measured, grab-and-go AHA step for dull-looking skin.

Key ingredients: Lactic Acid, Glycolic Acid, Aloe, Hyaluronic Acid.

Price: $39 for 60 pads.

Worth knowing: No acid percentage is stated, so its strength is hard to compare with the percentage-labeled entries.

9. ALASTIN ReSURFACE Skin Polish

This rinse-off polish combines Glycolic Acid with Perlite, a volcanic mineral, for what the brand calls dual-action exfoliation. You massage a nickel-sized amount onto wet, cleansed skin for about 30 seconds, then rinse. ALASTIN says the Glycolic Acid is included at a low level, alongside Arginine, and the base includes Caprylic/Capric Triglyceride, Glycerin, and Squalane. In the brand’s before-and-after photos, the polish was used once a week as part of a regimen, so it suits an occasional step more than a daily one.

Best for: An occasional rinse-off polish for smoother-feeling, brighter-looking skin.

Key ingredients: Glycolic Acid, Perlite, Squalane, Lactoferrin.

Price: $78 for 2.3 fl oz (68 ml).

Worth knowing: It has the highest price on the list, and ALASTIN’s FAQ notes it may not be ideal for skin with redness or sensitivity, or for anyone reactive to Glycolic Acid.

How to Choose an AHA Exfoliant

• Which acid suits your skin: Glycolic Acid is in seven of these nine formulas, from Pixi’s 5% to The INKEY List’s 10%. If you’d rather start with a formula its brand describes as gentle, the Lactic Acid serum from Biossance or the Mandelic Acid serum from Naturium may be the easier first step.

• Leave-on, pad, or rinse-off: A gel, toner, serum, or cream stays on skin, so it tends to suit a regular evening step. The StriVectin and First Aid Beauty pads give a set amount per swipe, and the ALASTIN polish comes off after about 30 seconds.

• Fragrance, essential oils, and alcohol in the INCI: Paula’s Choice, Naturium, Neostrata, First Aid Beauty, and ALASTIN list no Fragrance/Parfum. Pixi lists Parfum/Fragrance, Biossance lists Lavender Oil, StriVectin lists Grapefruit Peel Oil, and The INKEY List and StriVectin both include a form of Alcohol.

• How often to use an AHA exfoliant: The American Academy of Dermatology notes that the more aggressive the exfoliation, the less often it needs to be done, and that over-exfoliating could leave skin red and irritated. It also suggests considering products you already use, such as a Retinoid or Retinol, which may make skin more sensitive.

Frequently Asked Questions

What Is the Best AHA Exfoliant?

It depends on how you want to use it. For a plain, fragrance-free leave-on gel, Paula’s Choice Skin Perfecting 8% AHA Gel Exfoliant is the most straightforward pick. The INKEY List Glycolic Acid Toner offers a stated 10% at the lowest price, Naturium Mandelic Topical Acid 12% is the pick for easing in with a formula its brand calls gentle, and Neostrata Glycolic Renewal Smoothing Cream folds an AHA into the moisturizer step.

What Is the Best Glycolic Acid Exfoliant?

Three entries here state their Glycolic Acid percentage: Pixi Glow Tonic at 5%, Paula’s Choice Skin Perfecting 8% AHA Gel Exfoliant at 8%, and The INKEY List Glycolic Acid Toner at 10%. Pixi’s toner has the lowest percentage to start with, the Paula’s Choice gel suits a regular leave-on step, and The INKEY List toner is the one to build up to a few evenings a week. Neostrata’s cream uses a 10% blend of Glycolic and Citric Acids.

What Is the Best Chemical Exfoliant?

A chemical exfoliant uses acids, such as alpha and beta hydroxy acids, to loosen buildup on the skin, while a mechanical exfoliant uses a scrub or tool, as described by the American Academy of Dermatology. For the look of rough texture and dullness, an AHA, such as Glycolic or Lactic Acid, is the usual choice, and the picks above cover it. The StriVectin pads combine an AHA with a BHA and a PHA, and the ALASTIN polish pairs Glycolic Acid with a physical exfoliant.

How Often Should You Use an AHA Exfoliant?

Brand directions on this list range from a few times a week (The INKEY List, Naturium, and Pixi for sensitive skin) to up to twice daily (Paula’s Choice and Neostrata, once your skin adjusts). Building up gradually tends to help. A 2026 review in Frontiers in Cellular and Infection Microbiology cautions that aggressive exfoliation with hydroxy acids can compromise the moisture barrier, so visible redness, stinging, or flaking is a sign to cut back.

Do You Need Sunscreen When Using an AHA Exfoliant?

Yes, it’s especially important. FDA’s recommended Sunburn Alert for cosmetics containing AHAs reads: “This product contains an alpha hydroxy acid (AHA) that may increase your skin’s sensitivity to the sun and particularly the possibility of sunburn. Use a sunscreen, wear protective clothing, and limit sun exposure while using this product and for a week afterwards.”

Can You Use an AHA Exfoliant With Retinol?

Alternating them, rather than layering, is one way to approach it. The American Academy of Dermatology notes that products with a Retinoid or Retinol may make skin more sensitive, and that exfoliating while using them may worsen visible dryness. Biossance, for example, suggests alternating days between its Lactic Acid serum and a conventional Retinol.
