Frequently Asked Questions

What are the uses of salicylic acid?

Salicylic acid acts as a keratolytic (it serves as a peeling agent). Salicylic acid facilitates and makes the outer layer of the skin to shed. The topical salicylic acid (for the skin) is used to treat acne, dandruff, seborrhea, or psoriasis and to remove cotton, calluses, and warts. Salicylic acid is found in many daily use products.

Salicylic acid works by loosening and breaking apart desmosomes in the outer layers of the skin, which are attachments between cells. This action helps the skin to exfoliate and the pores to unclog. Salicylic acid is capable of reducing sebum secretion, which is another way to help reduce acne.
