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.

Key properties & actions

Lactic acid is known as an AHA-class ingredient derived from milk or fermentation processes. It is believed to loosen the bonds between dead skin cells to help them shed naturally, while also functioning as a humectant that draws moisture to the skin.

How to manage

Because its molecular size is larger than glycolic acid, it penetrates more gradually and is considered relatively gentle, making it a recommended option for those new to chemical exfoliation or for sensitive skin types. It is advisable to start with a low concentration once or twice a week, and sunscreen should be applied during the day after use. If stinging or redness persists, discontinue use and consulting a dermatologist is recommended.

Good to know alongside

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

Everyday care tips

After exfoliation, it is important to follow up with adequate moisturizing and soothing care to help maintain the skin barrier.
