Product Usage
Salicylic acid is an FDA-approved skincare ingredient commonly used for the topical treatment of acne. It is the only beta hydroxy acid (BHA) widely applied in skincare formulations. Particularly suitable for oily skin, salicylic acid is well known for its ability to deeply cleanse excess oil from pores and help reduce future oil buildup.
By keeping pores clear and unclogged, salicylic acid helps prevent the formation of whiteheads and blackheads. It also works as an exfoliating agent, removing dead skin cells from the surface of the skin. Due to its anti-inflammatory properties, it is also beneficial for individuals with conditions such as psoriasis.
Salicylic acid occurs naturally in willow bark, sweet birch bark, and wintergreen leaves, although synthetic forms are commonly used in modern skincare products.
