What is it

What are Lactic Acid and Glycolic Acid?

Lactic acid and glycolic acid are alpha hydroxy acids (AHAs) - two of the most well-studied surface exfoliants in dermatology. Glycolic acid is the smallest AHA molecule, allowing it to penetrate deeply for stronger renewal; lactic acid is slightly larger and gentler, with the added benefit of humectant activity. Together, they offer a balanced approach to chemical exfoliation - dissolving dead cell bonds to reveal smoother, brighter skin and enhance the penetration of other actives.

Benefits

What do Lactic Acid and Glycolic Acid do for your skin?

AHAs dissolve the bonds between dead surface cells, promoting turnover and revealing smoother, brighter skin. Surface renewal complements deeper cellular regeneration from retinol. Key actions include:

Exfoliates surface and deeper layers of the skin
Improves texture and tone evenness
Promotes cellular turnover for smoother, more refined skin
Lactic acid also provides humectant hydration benefits
Enhances the penetration and efficacy of other actives

How to use

How do Lactic Acid and Glycolic Acid fit your routine?

AHAs are typically found in evening serums, exfoliating treatments, and targeted body products. Start 2-3 times per week and build gradually to nightly as tolerated. Always use daily SPF - AHAs increase sun sensitivity.

Who should use it

Who should use Lactic Acid and Glycolic Acid?

Appropriate for most skin types, particularly those concerned with texture, dullness, or visible aging. Very sensitive or compromised skin should start slowly or consult a dermatologist. Daily SPF is essential.
