Lactose
Explained
Lactose is a naturally derived milk sugar with humectant and skin conditioning properties. It helps draw and hold moisture in the outermost layer of skin.
The Cosmetic Ingredient Review (CIR) concludes lactose is generally considered low risk for irritation in topical products.
By the way, lactose is not an exfoliating acid like lactic acid or lactobionic acid. And since it's typically animal-derived, it's not usually vegan.
