Ingredient

Lactic Acid

An alpha hydroxy acid that exfoliates and also acts as a humectant, so it is often chosen as a gentler option.

What it does

  • Exfoliant

    Loosens or dissolves the bonds between surface skin cells.

  • Humectant

    Draws water into the upper layers of the skin or hair.

What we tell people

  • Contains exfoliating acids

    This product contains an exfoliating acid. These work by loosening the bonds between surface skin cells, and are usually introduced gradually.

    Why: Concentration and pH change the effect substantially, and neither is usually disclosed, so an absolute statement would be misleading.
