Chemical peels: their place within the range of resurfacing techniques

Abstract

The photoaging index has been developed to determine the level of skin rejuvenation required to reduce the visible signs of aging. Minor photoaging is reversed with free-radical avoidance and peeling with a topical skin care regimen consisting of buffing grains, alpha-hydroxy acid normalizing tonics and vitamin A conditioning lotions. The reversal of moderate photoaging requires the addition of light-to-moderate peels using alpha-hydroxy acids combined with microdermabrasion. For the more advanced case the Jessner/trichloroacetic acid (TCA) combination peel (Monheit peel) is used which can be repeated once to twice a year. Laser resurfacing is especially useful to shrink the collagen and produce a 'face-lift bypass'. The phenol peel remains the standard to reverse heavy lines. A new modified formula (Hetter) is used which contains less phenol and less croton oil. Dermabrasion is helpful for removing multiple actinic keratosis. With this combination of skin care, chemical peels, and dermabrasion it is possible to reverse the photoaging index.
