Salicylic acid is the main ingredient in Salicylic facials, a type of facial commonly used to treat skin and hair conditions such as dandruff, acne, warts and psoriasis. It works by penetrating the skin and causing stimulation, which encourages the skin to renew itself, and shed old skin. It can be very harsh on the skin, however, so diluting the acid is recommended to prevent damage or irritation.
