AHA alpha hydroxy acids target and remove dull, dry surface skin cells allowing them to be exfoliated, revealing the underlying wrinkle-free, firm and glowing skin beneath. This action increases your skin cell turnover therefore increasing collagen (smoothness of skin), elastin (firmness of skin) and can even reduce the colour of acne scars.
 
BHA beta hydroxy acids are oil soluble, they penetrate deeper than your skin's surface skin so effectively clean out clogged and large pores, even those that cause acne. BHAs are more effective and less irritating than AHAs in tackling whiteheads, blackheads, and acne.

According to studies, using AHA and BHA acids together creates thicker and stronger skin due to the increase in collagen that makes the layers of the skin visibly plumper.
