Background: Redundant and wrinkled face is a common finding in patients with long-standing leprosy, which is responsible for the appearance of premature aging. Chemical peeling plays a role in dermal regeneration in the treatment of wrinkles. However, the effect of chemical peeling has rarely been studied in patients with leprosy.
Objective: To investigate the effect of chemical peeling on dermal connective tissue components and clinical improvement of facial wrinkles in patients with leprosy.
Methods: Five patients with clinically and bacteriologically inactive lepromatous leprosy were treated with 70% glycolic acid plus 35% trichloroacetic acid (GA-TCA). Histologic and clinical changes were evaluated at 0 and 90 days postpeel.
Results: Histologically, collagen fibers and ground substance increased significantly but elastic fibers did not change at 90 days postepeel. Clinically, fine wrinkles improved considerably, whereas most deep wrinkles remained unchanged at day 90.
Conclusion: This study demonstrates that chemical peeling with GA-TCA, or medium-depth peeling, causes an increase in collagen and ground substance but not in elastic fibers. These changes result in limited clinical improvement in the facial wrinkles of leprosy patients. Therefore, medium-depth chemical peeling may be insufficient to improve the premature aging appearance in patients with leprosy.
