What is salicylic acid?
Salicylic acid is a beta-hydroxy acid (BHA), which is a type of exfoliating acid. The other type is AHA, or alpha hydroxy acid, and this includes ingredients such as glycolic and lactic acid.
A beta-hydroxy acid is one where the hydroxy part of the molecule is separated from the acid part by two carbon atoms. This structure makes it more oil-soluble, allowing it to penetrate deeper into the pores of the skin
Salicylic acid has anti-inflammatory and antibacterial properties.
