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.
