The effects and hazards of salicylic acid

Many things have both good and bad sides, just like drugs have many side effects while treating human diseases. Salicylic acid is an ingredient in cosmetics, and many acne-removing medicines also contain salicylic acid. The function of salicylic acid is to disinfect and remove acne, but it also has certain side effects when people use it. Long-term use can cause human dependence.
