What is Lactic Acid?

A gentle AHA with moisturizing properties that simultaneously exfoliates and hydrates

Larger molecular size than glycolic acid makes it less irritating. Suitable for sensitive skin exfoliation and skin tone improvement.

Main causes & characteristics of Lactic Acid

Lactic acid is known to be an AHA (alpha-hydroxy acid) derived from milk or fermentation processes. It is known to help loosen the bonds between dead skin cells so that old keratin sheds naturally, while also functioning as a humectant that draws moisture to the skin.

Managing Lactic Acid

Because its molecular size is larger than glycolic acid, penetration is more gradual, making it relatively gentle and well-suited for those new to exfoliation or with sensitive skin. Starting at a low concentration one to two times per week is recommended, and sunscreen should be applied during the day after use. If stinging or redness persists, discontinuing use and consulting a dermatologist is recommended.

Related information

Lactic acid is known to be frequently mentioned alongside other AHAs such as glycolic acid and mandelic acid, as well as BHAs and PHAs in the context of exfoliation.

Everyday care tips

After exfoliation, applying sufficient moisturizer and soothing care is recommended to prevent compromise of the skin barrier.
