It's well known that exfoliation of the outer layers of the skin gives you positive outcomes. An equally important aspect of resurfacing treatments such as chemical exfoliation and microdermabrasion is the goal to, in a very controlled manner, stimulate the wound response. This response initiates the growth of new cells resulting in a healthier appearance and smoother texture. Cellular turnover is a natural process during which dead skin cells are released from the top layers and replaced with new cells. Unfortunately, this natural exfoliation decreases with age starting around the age of 27. This decrease can contribute to fine lines, wrinkles, acne, and a dull, dry appearance. Stimulating the rate of exfoliation in a controlled manner with resurfacing treatments can reduce imperfections while simultaneously building healthier skin structures. There are several methods of chemical exfoliation and clients' treatments are customized based on skin analyses and goals. Progressive treatments allow clients to have optimal results with little-to-no downtime associated with resurfacing treatments. For optimal results, chemical exfoliation and microdermabrasion are most commonly done in a series spaced three weeks apart. Although if the skin is sensitive it is recommended to wait for four weeks.
