Uses and benefits of Salicylic acid on the Skin

Salicylic acid is a colorless, bitter-tasting solid, it is a precursor to and a metabolite of aspirin (acetylsalicylic acid). It is a plant hormone,and has been listed by the EPA Toxic Substances Control Act (TSCA) Chemical Substance Inventory as an experimental teratogen.It works by increasing the amount of moisture in the skin and dissolving the substance that causes the skin cells to stick together. This makes it easier to shed the skin cells. Warts are caused by a virus. Salicylic acid does not affect the virus.

Uses

Salicylic acid as a medication is commonly used to remove the outer layer of the skin. As such, it is used to treat warts, psoriasis, acne vulgaris, ringworm, dandruff, and ichthyosis.

Similar to other hydroxy acids, salicylic acid is an ingredient in many skincare products for the treatment of seborrhoeic dermatitis, acne, psoriasis, calluses, corns, keratosis pilaris, acanthosis nigricans, ichthyosis, and warts.

Uses in manufacturing

Salicylic acid is used as a food preservative, a bactericide, and an antiseptic.

Salicylic acid is used in the production of other pharmaceuticals, including 4-aminosalicylic acid, sandulpiride, and landetimide (via salethamide).

Benefits to skin

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.

Once it penetrates the skin, salicylic acid "dissolves skin debris that clogs pores, [acts] as an anti-inflammatory, and also helps red, inflamed pimples and pustules go away faster," explains Naissan O. Wesley, M.D., a board-certified dermatologist in Los Angeles.
