Abstract
Aging is a complex, multifactorial process resulting in several functional and esthetic changes in the skin. These changes result from intrinsic as well as extrinsic processes, such as UVR. Recent advances in skin biology have increased our understanding of skin homeostasis and the aging process, as well as the mechanisms by which UVR contributes to photoaging and cutaneous disease. These advances in skin biology have led to the development of a diversity of treatments aimed at preventing aging and rejuvenating the skin.
The face and, in particular, the eyes are often used as an immediate gauge of chronologic age. Consequently, many rejuvenative treatments are directed to the improvement, if not elimination, of rhytides in the periorbital area.
The various treatment options for the aging face ranges from prevention with sunscreens and moisturizers, to medical treatments with topical agents, and on to the more invasive techniques such as chemical peels, BTX and collagen injections, dermabrasion, and laser resurfacing procedures.
One of the rejuvenating procedures is chemical peeling; also known as chemoexfoliation or derma-peeling, which involves the application of an acid to the skin to produce controlled, predictable injury to the epidermis and variable portions of the dermis. Clinical improvement is produced after subsequent reepitheliazation.
