Brief
Salicylic Acid (CAS No. 69-72-7) is a well-known beta hydroxy acid (BHA) widely used in cosmetics, dermatology, and pharmaceuticals. Naturally derived from willow bark, it has powerful exfoliating, anti-inflammatory, and acne-fighting properties. As one of the most trusted ingredients in skincare, salicylic acid is particularly effective for treating oily, acne-prone, and congested skin.
What is Salicylic Acid?
Salicylic acid is a lipid-soluble organic acid with a unique ability to penetrate deep into pores, unlike water-soluble alpha hydroxy acids (AHAs). This allows it to exfoliate from within, helping to dissolve oil, dead skin cells, and debris that can clog pores and lead to breakouts.
It is both naturally derived and synthetically produced, and has been used for centuries in traditional medicine to reduce inflammation and pain, as well as in modern skincare as a reliable treatment for acne, blackheads, and keratosis pilaris.
