“…5,6,25 This procedure was not performed in order to analyze its effectiveness on skins not subjected to this pretreatment, since this practice is commonplace in medical offices. Thus, it can be verified that even in the absence of pretreatment, the results obtained were satisfactory, highlighting the relevance of the study.…”

“…5,7,8 Its effect depends on how long it remains on the skin (the longer the period, the stronger the action) and its concentration. To put an end to the peeling effect using glycolic acid, it is necessary to use a formulation that provides acid neutralization, or that can be washed with water.…”

BACKGROUND:Peeling is a procedure which aims to accelerate the process of skin exfoliation.OBJECTIVES Development of formulations containing lactic acid at 85% or glycolic acid at 70% and the evaluation of these formulations on clinical efficacy in reduction of fine wrinkles. METHODS Preliminary stability tests were carried out and an in vivo study was performed with three groups with 9 representatives each. One was the control group, which used only sunscreen; another one used lactic acid+sunscreen, and the last group used acid glycolic+sunscreen. Clinical efficacy was assessed with a CCD color microscope, through the digitization of images before and after treatment. The applications were carried out by a dermatologist, once a mont h every 30 days, during 3 months. The area with wrinkles was calculated by planimetry point counting, in accordance with Mandarin-de-Lacerda. RESULTS The formulations were stable in the visual and Ph evaluation. There was no improvement in the control group; for lactic acid, there was significant improvement after the second peeling application on the outer lateral area of the right eye and after the third application on the outer lateral area of the left eye. For the glycolic acid group, there was significant improvement in the outer lateral area of the left eye after the first application, and of the right eye region, after three applications. The formulations used must be kept under refrigeration and should be manipulated every 30 days. CONCLUSIONS Both peelings were effective in reducing fine wrinkles of the outer lateral eye area after three applications (p≤0.05%). It was observed that peeling efficacy in the external-lateral region of one eye might be different compared with that in skin of the external-lateral region of the other eye, relative to the speed of skin improvement.
