Chemical peels
Medium-depth peels such as those using trichloroacetic acid (TCA) may have unpredictable penetration. For deep peels, one study using phenol showed an improvement of greater than 50% in 7 out of 11 patients. However, long-lasting adverse effects were also reported.75 High concentration TCA has also been studies; patients were treated with either 65% or 100% TCA, and more than half of the patients in both groups showed significant improvement. In addition, multiple treatments using 100% TCA resulted in more than 70% improvement.76โ78 In one study comparing the effects of 100% TCA to the effects of skin needling, the improvement rates were 75.3% and 68.3%, respectively, after four sessions.79
