AHA, BHA, and PHA - What are chemical exfoliants?

Before We Go On

- 

By now there are so many articles about chemical exfoliants. Chemical exfoliants can be found in all sorts of skincare products from cleansers to concentrated toner pads. For good reason - chemical exfoliants are great ways to increase the skin cell regeneration process while improving overall skin health. There are three main types of chemical exfoliants that you'll find in the market: AHA's, BHA's, and PHA's. 

AHA's or Alpha Hydroxy Acids (most commonly Glycolic acid, and Lactic acid) 

Alpha Hydroxy Acids, naturally found in fruits, milk, and sugar cane. AHA's are ideal for mature and/or dry skin. It stimulates the skin cell regeneration process and exfoliates the skin. You can expect improved cell renewal, pigmentation improvement, and an evener skin tone. It has the ability to lock in moisture which reduces fine lines and gives your skin a radiant look.

BHA's or Beta Hydroxy Acids (most commonly Salicylic acid and other salicylates) 

BHA's can be found in aspirin or white willow trees. This exfoliant is most recommended for oily skin and/or acne-prone skin because of its' ability to dissolve oils in pores without irritating the skin. Its anti-inflammatory properties are ideal for even the most sensitive skin. Like AHA's, BHA's also increases the speed of skin cell regeneration. 

PHA's or Poly Hydroxy Acids (gluconolactone, galactose, and lactobionic acid)
