For the first step in exfoliation, Salicylic Acid works best to remove those damaged layers of cells that build up on your skin surface daily. Salicylic Acid, a Beta-Hydroxy Acid, is a highly effective superficial peeling agent and pore cleanser. Salicylic Acid loosens and removes aging and dead skin cells, oil and debris attached to the skin's surface, stimulating new skin cell production and increasing collagen formation. As Salicylic Acid is oil-soluble and lipophilic, it penetrates sebum filled follicles and cleans out clogged pores, resulting in marked improvement in acne prone skin. Regular use of Salicylic Acid will result in a decrease in fine lines, smoother skin, more even pigmentation and a reduction in pore size.
