Salicylic Acid

Beta Hydroxy Acid

Also known as: Beta hydroxy acid, BHA, 2-Hydroxybenzoic acid

Description

Salicylic acid is a lipophilic beta hydroxy acid with keratolytic, comedolytic, and mild anti-inflammatory properties. Its oil solubility allows penetration into the pilosebaceous unit. [Arif 2015]

Mechanism of Action

Dissolves intercellular cement in the stratum corneum, promoting desquamation. Penetrates lipid-rich environments of clogged pores, reducing comedone formation. Exhibits mild anti-inflammatory activity via prostaglandin inhibition. [Arif 2015]
