Why doesn Paula make a face scrub?
Topical scrubs are simple ways to mechanically exfoliate skin, but these can be abrasive and harsh on the skin, and they also exfoliate unevenly. A good deal of research has established that chemical exfoliants such as salicylic acid (BHA) and alpha hydroxy acids (AHAs) are not only effective for gently removing excess surface cells, but they also increase collagen production, promote cell turnover, reduce the appearance of skin discolorations, and improve the overall health of the skin. These additional benefits make an AHA or BHA product preferred to exfoliating skin with a topical scrub.
