Salicylic Acid: Acne is formed when skin cells inside hair follicles shed too fast and clump together, plugging up the follicle and causing a pimple. Salicylic acid helps slow down shedding of the cells inside the follicles, preventing clogging. Salicylic acid also helps break down blackheads and whiteheads.
Salicylic acid is especially helpful in treating acne because of its ability to penetrate the follicle. It encourages the shedding of dead skin cells from within the follicle, helping keep the pores clear of cellular debris. In this way, it reduces the number of pore blockages and breakouts on the skin.
