Salicylic Acid
Salicylic acid is one of acne’s biggest enemies. Salicylic acid is a lipophilic monohydroxybenzoic acid, a type of phenolic acid, and a beta-hydroxy acid. The hydroxy part of the molecule is separated from the acid part by two carbon atoms, as opposed to an alpha hydroxy acid where they’re separated by one carbon atom. This structure is important because it makes salicylic acid more oil-soluble so it can penetrate into the pores of the skin. Oil-soluble ingredients can penetrate the skin at a deeper level than their water-soluble counterparts.
Salicylic Acid
Salicylic acid removes dead skin and can improve the texture and color of sun damaged skin. It penetrates oil-laden hair follicle openings and, as a result, also helps with acne. Salicylic acid can get deep into your skin to do its job. This quality is precisely what makes it such a potent ingredient for targeting acne — especially for blackheads and whiteheads. Salicylic acid dissolves skin debris that clogs pores, acts as an anti-inflammatory, and helps red, inflamed pimples and pustules go away faster. Studies have shown that salicylic acid is less irritating than skin care products containing alpha-hydroxy acids while providing similar improvement in skin texture and color. Salicylic acid-based products are safe to use daily if used as directed and tolerated by your skin.
