What Lactic Acid Does For The Skin
Exfoliator / Humectant
Lactic Acid, like other alpha-hydroxy acids (AHAs), acts to exfoliate the surface level of the skin helping with the appearance of texture, signs of aging, and uneven skin tone. Unlike other AHAs, lactic acid is also a component of the skin's natural moisturing factors (NMF) which are key components needed to maintain a healthy skin barrier and skin hydration.
Lactic Acid Under The Microscope
Lactic Acid is an alpha hydroxy acid (AHA) that acts as a gentle exfoliant, helping to remove dead skin cells, revealing more even-toned skin. It's known for keeping skin hydrated, making it a good option for people with dry or sensitive skin. Using lactic acid regularly can improve skin texture, reduce the appearance of fine lines, and brighten the complexion. Compared to glycolic acid, another common exfoliant, lactic acid has a higher molecular weight, which allows for a gentler exfoliation and makes it less irritating for the skin.
