What is SALICYLIC ACID used for?

Salicylic acid is an exfoliating agent that can handle acne very well. Its complicated structure makes it more oil-soluble and thus it can penetrate into the skin’s pores. Face washes with salicylic acid or cleansers with salicylic acid are commonly available due to this reason. It also works as a hair-conditioning and anti-dandruff agent.

Skin care: It is a potent anti-acne ingredient especially for whiteheads and blackheads. It penetrates deeply into the skin, dissolves the skin debris that clogs the pores and is anti-inflammatory. Blackheads (open plugged pores), whiteheads (closed plugged pores), or pimples (pustules) frequently develop when your hair follicles (pores) become clogged with dead skin cells and oil. The dead skin cells clogging your pores are removed by the skin-penetrating action of salicylic acid. Salicylic acid is a keratolytic drug, making it ideal for the most thorough exfoliation

Origin

The Kolbe-Schmitt reaction, also known as high pressure and high temperature treatment of sodium phenolate with carbon dioxide, is the process used in the manufacture of sodium salicylate. Salicylic acid is produced by acidifying the product with sulfuric acid. Aspirin (acetylsalicylic acid) or methyl salicylate (oil of wintergreen) can also be hydrolyzed with a potent acid or base to create it.
