The study was conducted in Arestetic Clinic Galai during the period 10 Dec. 2015-1 Nov. 2016, on a group of 12 patients, of which 10 women and 2 men. The product used was Easy TCA 50% manufactured by SkinTech laboratories. Three coats of TCA were applied at intervals of 4 minutes each. The end result was assessed at 21 days, when the entire surface of the skin was peeled and re-epithelized. Patients were asked to assess the degree of satisfaction on a scale of 1 to 10, with 1 being the least satisfactory and 10 being the most satisfactory. As a result of this assessment, 10 patients rated the degree of satisfaction with 10 (83%) and 2 patients rated the degree of satisfaction with 9 (17%), with an average degree of satisfaction of 9.83. At 21 days, dyschromias and hyperpigmentations completely disappeared in 9 patients, while a female patient and 2 male patients still presented with barely noticeable spots. These three persons were subjected to the second peeling after 2 months, this time in two layers, and these hyperpigmentations disappeared at the end.
