When it comes to acids and the skin, people seem to have a genuine fear of what it can do, but there is nothing to fear. Acids can be your skin’s best friend, especially when treating breakouts, texture and hyperpigmentation, their strength is what will alter the skin’s overall complexion. Salicylic acid in particular is part of the family that will transform your skin.
There are two types of acids and more often than not the skincare that you come across is split between beta hydroxy acids (BHAs) and Alpha Hydroxy Acids (AHAs), Salicylic acid is a beta hydroxy acid. Another element to note is that BHAs are oil soluble whereas AHAs are water-soluble, for the skin this means that BHAs can penetrate the skin at a deeper level whereas a water-soluble will alter the surface. In essence, AHAs work to loosen dead skin cells and reveal a fresher complexion and BHAs, through penetrating the dermis, will unclog pores.
Understanding its structure, the important thing to take away from salicylic acid is that as a BHA and derived from willow bark, it can penetrate the skin at an impressive rate that can deliver the changes we all desire for our skin.
