Salicylic Acid is a natural substance obtained from the bark of the willow or birch tree. The acid, depending on its concentration, offers several benefits. At low concentrations, the acid promotes skin growth. At higher concentrations, the acid helps the skin to peel, making it perfect for acne and psoriasis treatments. It can also substantially reduce sebum production, combating oily skin. Salicylic Acid creams are recommended to be used at night, in the summer due to the sun’s rays.
