Beta Hydroxy Acid
Beta hydroxy acid/salicylic acid is a fantastic ingredient for treating acne as it not only helps to clear blocked pores but also reduces inflammation. It works in a similar way to alpha hydroxy acids (AHAs), refreshing the skin by giving it a chemical exfoliation. It does this by dissolving the bonds that keep old, dead skin cells onto the skin’s surface. The main difference is that BHA is oil-soluble, so it can also dissolve its way into blocked, oily pores while most AHAs are water-soluble, so they just give a surface exfoliation of the skin.
