Smoother, more even-toned skin often starts with regular chemical exfoliation, and lactic acid is one of the gentler alpha hydroxy acids that can help get you there. It works by loosening the bonds that hold dull, dead skin cells on the surface, revealing fresher skin underneath without the abrasion of a physical scrub. This makes it a popular choice for anyone dealing with rough texture, fine lines, or lingering dark spots — and today there are formulas tailored to almost every comfort level and budget.
How we choose
The idea is simple: a well-chosen exfoliant can slot into your existing routine and over time improve luminosity and smoothness with minimal disruption. The eight products highlighted here range from a high-potency lactic acid treatment that promises visible results in minutes to hydrating overnight gels and convenient pre-soaked pads. Each option brings a slightly different approach to resurfacing the skin, and this roundup is designed to help you find a fit for your own pace and priorities.
Our 8 Picks
Sunday RileyGood Genes All-in-One Lactic Acid Treatment Face Serum
What it is
A leave-on lactic acid treatment serum designed to exfoliate and brighten the skin's surface.
Why it's worth it
This serum uses purified lactic acid to gently resurface the skin, helping to reduce the look of fine lines and dark spots. The brand states it can improve the appearance of lines and wrinkles in as little as three minutes. It is well suited to those who want a multi-tasking treatment that both exfoliates and hydrates without irritation.
Caveat
The higher concentration may be too strong for very sensitive skin if left on overnight.
Sunday RileyGood Genes All-in-One Lactic Acid Treatment Face Serum
What it is
A smaller-sized lactic acid treatment serum that delivers the same exfoliating and brightening benefits as the full-size version.
Why it's worth it
This travel-friendly size offers the same high-potency lactic acid formula for resurfacing dull skin and fading discoloration. It works as a leave-on treatment or a short-contact mask for those new to acids. A good fit for anyone wanting to trial the product before committing to a larger bottle.
Caveat
The smaller bottle contains only 0.5 oz, so it will run out faster with daily use.
The OrdinaryLactic Acid 5% + Hyaluronic Acid 2%, Gentle Exfoliating Serum for Smoother Skin
What it is
A water-based serum with 5% lactic acid and hyaluronic acid for gentle daily exfoliation.
Why it's worth it
The mild concentration makes it ideal for beginners or those with dry or sensitive skin who want to introduce lactic acid slowly. Added hyaluronic acid helps maintain hydration, while Tasmanian pepperberry extract is included to reduce potential irritation. It is well suited to someone looking for an affordable, no-fuss exfoliating serum that won't strip the skin.
Caveat
At 5% strength, it may not deliver dramatic results for those with more stubborn texture or hyperpigmentation.
The OrdinaryLactic Acid 10% + Hyaluronic Acid 2%, High-Strength Exfoliating Serum for Smoother, Brighter Skin, 1 Fl Oz
What it is
A high-strength lactic acid serum with 10% concentration and hyaluronic acid for deeper exfoliation.
Why it's worth it
The higher percentage offers more intensive surface exfoliation, which can help improve uneven texture and enhance luminosity more noticeably than a lower strength. Hyaluronic acid provides hydration, and the formula again includes Tasmanian pepperberry extract to help calm the skin. A good fit for experienced acid users who want a budget-friendly but effective resurfacing serum.
Caveat
The 10% strength can cause tingling or irritation on sensitive skin, so patch testing is recommended.
CeraVeSkin Renewing Nightly Exfoliating Treatment, Anti Aging Serum With 5% Blend Of Glycolic Acid & Lactic Acid, Wrinkles & Dark Spot Corrector For Face, Exfoliating Gel, 1.7 Oz
What it is
An overnight treatment gel that combines a 5% blend of glycolic and lactic acids with ceramides for barrier support.
Why it's worth it
The dual-acid formula gently exfoliates while the ceramides help maintain the skin's natural moisture barrier, making it less likely to cause dryness. Licorice root extract is included to assist with brightening dark spots. It is well suited to those who want a hydrating exfoliant that also strengthens the skin barrier overnight.
Caveat
Contains glycolic acid in addition to lactic acid, so it may not be ideal for those seeking a pure lactic acid product.
THAYERSExfoliating 2% AHA Toner Pads, Dual-Sided Exfoliating Pads with Witch Hazel, Glycolic Acid and Lactic Acid to Resurface Skin Texture and Instantly Brighten, For All Skin Types, 60 Count
What it is
Pre-soaked toner pads containing a 2% AHA blend of glycolic and lactic acids for daily exfoliation.
Why it's worth it
These pads offer a convenient, pre-measured way to exfoliate and resurface the skin without the guesswork. The dual-sided texture allows for gentle or more targeted application. The brand states they are clinically tested to smooth texture in one week and even skin tone in two weeks. A good fit for those who prefer a quick, no-mess exfoliating step in their routine.
Caveat
As a toner pad, it is not a leave-on serum and may not provide the same prolonged exfoliation as a serum.
Paula's ChoiceSKIN PERFECTING 8% AHA Exfoliant, Gel Exfoliant with Glycolic Acid Chamomile & Green Tea, Leave On Gentle Face Exfoliator for All Skin Types, Fragrance- Free
What it is
A leave-on gel exfoliant with 8% glycolic acid, chamomile, and green tea to smooth skin texture and improve radiance.
Why it's worth it
The glycolic acid helps dissolve dead skin cells and reduce the appearance of discoloration, while antioxidants like green tea soothe and protect. This lightweight gel absorbs quickly and can be used daily. It is well suited to those who want an effective AHA exfoliant with added calming ingredients, though it uses glycolic rather than lactic acid.
Caveat
Contains glycolic acid, not lactic acid, so it may not be suitable for those specifically seeking a lactic acid product.

What it is
