Overview Chemical Peel

Photodamaged (sun-damaged) skin has wrinkles, textural alterations, dyspigmentation, yellowing, thinning and mottling.

Types of Chemical Peels

Glycolic acid is the mildest form of chemical peel. Jessner's solution is an intermediate depth peel and is often used immediately prior to TCA peel. TCA is used in different concentrations to be either a superficial (20-30%) or medium depth peel (30-50%). Phenol based peels are the deepest. In strong concentrations phenol preparations are potentially cardio and renal toxic.

TCA 20 - 50% is a medium depth chemical peel that has a depth of penetration to the papillary dermis and upper reticular dermis. It helps reverse solar lentigenes, actinic keratoses and improving skin texture but has only a marginal effect on fine wrinkles. It tightens the skin. It helps corrects epidermal atrophy and atypia and helps lay down new sub-epidermal collagen. It is a peel, and the superficial layers will exfoliate and re-epithelialise, so the patient will look as though they have moderate sunburn for two to three weeks.
