Histological Comparison Between Deep Chemical Peeling DE ROSSI FATTACCIOLI’s Formulae) and Ultra-Pulsed CO2 Laser Resurfacing

Abstract

The laser treatment of carbon dioxide ultra-pulsed and peelings chemical phenol-deep oil crotón (formulas BackerGordon and Litton) have been and remain the most used for the rejuvenation of the skin of the face. This study was conducted to compare the effects of both treatments by histological sections at different periods of the evolution of the same. Biopsies were performed face treaties skin before and retro immediately and 24 hours after the ablations CO2 laser and 24 hours after application of the formula of Litton for chemical peeling deep. Areas in areas near the biopsies were biopsied 12 hours, 24 hours, 1 week, 2 weeks, 2 and 3 months later, in the case of treatment with phenol 24 hours, 48 hours, 72 hours, 1 week, 1 year and 10 years later. The initial biopsies showed that being ablations CO2 laser deeper than the chemical peeling with phenol, a month both had formed an area neocolágeno. But after three months, the comparatively deep phenol chemical peeling (formula Litton) had been an area neocolágeno more compact and wide as that produced by the CO2 laser ultra-pulsed.
