Salicylic Acid
Anti-inflammatory salicylic acid is the most well-known beta hydroxy acid (BHA) for good reason. It doubles up on exfoliation, working deep into pores to de-clog and on the surface by digesting dead skin cells for a total skin refresh. Equally as effective at reducing lines and wrinkles thanks to its collagen-boosting benefits, salicylic acid is an essential addition to any skincare routine for both mature and acne-prone skin.
