Abstract:
Objective To promote the use of chemical peeling in facial rejuvenation with the phenol and croton oil peeling agents to the UVA/B-irradiated skin of hairless mice, and to provide the experimental evidence for the clinical application of the treatment of irradiated skin.Methods Sixty BALB/C hairless mice were photo-aged by use of chronic ultraviolet A and ultraviolet B irradiation for 20 weeks. After irradiation the animals were randomly divided into two groups:untreated (10 mice) and treated (50 mice). The phenol and croton oil chemical peeling agents were applied to the dorsal skin of treated animal group while it was full anesthetized. Punch biopsies were taken at 7, 14, 30, 60, and 90 days after peel for histological analysis. At 60 days after irradiation, the skin wrinkling of animals were analyzed by macroscopy, cleavage line amplification, and computer imaging analysis system. Results The treated areas of irradiated skin recovered rejuvenation and exhibited a unique connective tissue layer composed of fine collagen fibers beneath the epidermis. Conclusion The mixture of phenol-croton oil may reverses the visible stigmata of photoaging skin. Our results will be of great help to promote the use of chemical peeling in facial rejuvenation.
