Background: Microdermabrasion is a surface treatment, noninvasive, which uses a negative pressure and drives programmable inert microcrystals on the skin, causing an exfoliation. Objective: The aim of this study was to evaluate the effects of application of microdermabrasion in human skin rejuvenation. Methods: Eleven women who were undergoing abdominoplasty were considered. An area of 25 cm(2) in the umbilicus to the right was conditioned with microcrystals of Al2O3 in maximum flow, negative pressure of 200 mmHg and total of 8 past, the left side being used as control. The number of sessions ranged from one to five, with weekly intervals, and timing of sample collection ranged from 0 to 132 days. Samples were fixed in 10% formaldehyde in phosphate buffer and were evaluated histologically. Results: A mild to marked hyperpigmentation was observed and remained for a variable period. Histological findings suggest an improvement in the epidermal layer with increased thickness and reestablishing their interdigitations in the dermis initially observed an increase in collagen synthesis. The analysis showed a late stay of epidermal changes, which did not occur in the dermis. Conclusion: Under the conditions and parameters used in this work, the microdermabrasion had a positive skin structure, showing that a viable resource in promoting skin rejuvenation.
