5% L-Mandelic Serum

A lightweight, water-based exfoliating serum that combines 5% chirally correct L-Mandelic Acid with 4% L-Lactic Acid to gently sweep away dead skin cells, visibly improve tone and texture, and help keep skin clear — with notably less irritation than other AHAs. The 5% concentration is the recommended starting point for those new to AHAs, those with dry or sensitive skin, or anyone building tolerance before stepping up to a higher strength.

Who is this perfect for?

Suitable for all skin types, including sensitive skin. Especially well-suited for those dealing with inflamed or non-inflamed breakouts, post-acne marks, uneven skin tone, hyperpigmentation, fungal folliculitis, or dull, congested skin. The 5% strength is the ideal starting point for AHA beginners and those with deeper skin tones. 

How does it work?

L-Mandelic Acid has a higher molecular weight than other AHAs, which slows its penetration into the skin, resulting in more even, controlled exfoliation with lower irritation potential. At 5%, it gently loosens the bonds that hold dead skin cells to the surface, helping reveal a clearer, brighter-looking complexion over time. 4% L-Lactic Acid works alongside it to add a hydrating layer of exfoliation and further help visibly improve the appearance of post-acne marks. Niacinamide supports moisture retention and helps visibly improve the look of uneven tone and texture, while Sodium Hyaluronate and Sodium PCA keep the formula comfortable on the skin.
