Exfoliation is important to a healthy barrier function. However it needs to be done in precise increments to avoid over-exfoliation, which consequently can cause adverse effects. Over-exfoliated skin appears thin, fragile, too shiny, has broken capillaries, and can become sensitized and inflamed. iS Clinical cosmeceuticals are designed to gently exfoliate the skin, optimizing this natural process, to achieve improved skin health and vitality. iS Clinical professional products, in-office treatments, and Prodigy Peels may provide more intense exfoliation and their use should be guided by the individual’s skin condition, health, and ultimate goals as evaluated by the skin care practitioner. The amount of, and frequency of, exfoliation that is best for an individual is determined by that individual’s age, extent of photodamage, internal health, healing ability, metabolism, skin health, and any pre-existing skin conditions.
