Patients should discontinue their use of topical retinoic or Vitamin A creams 5 days prior to procedure. Concentrations of 50-70% glycolic acid are applied to the skin after an alcohol cleansing. Treatments take only 15-20 minutes leaving the skin feeling refreshed. Post peel a slight pink colouration resolves with minutes, up to 24 hours. Occasionally some flaking or slight crusting may occur for a few days. Sunscreen must be worn to protect the newly exposed layer of skin. Some results are visible immediately, but a series of 4-5 peels done one month apart are necessary for full effect. TCA Peel Trichloroacetic acid peels are commonly used for medium-depth peeling (though depth is adjustable) to treat fine surface wrinkles, superficial blemishes and pigment problems. There is downtime of (correction) approximately 5- 7 days with this procedure with a sun burn like reaction of pink to redness, a transient darkening of the skin and finally peeling. Gentle cleaning, frequent moisturizing, high SPF and strict sun avoidance is required after the peel and for the first 2 weeks following. The results of one TCA peel is slightly more efficacious that a series of 5 glycolic peels in regards to texture and colour improvements achieved.
