CHEMICAL PEELING IN
Dr Gloria Mmankurata Tshukudu & Dr ZF Annandale.
Background: Chemical peeling for skin of colour arose in Egypt, Mesopotamia and other ancient cultures in andaround Africa. Egyptians bathed in sour milk to smooth the skin utilising the properties of Alpha-hydroxy acids (AHAs).1Chemical peeling agents are varied. Superficial agents are many and varied. Superficial agents include Alpha HydroxyAcids (AHAs), salicylic acid, resorcinol, and Jessner's solution and trichloroacetic acid (TCA) at 10-35%concentrations. The most feared complication is scarring. Those at risk are patients with histories of poor healing andkeloid formation, patients undergoing deep peels patient recently on Accutane therapy and those who develop infectionduring the peel.2 In ethnic or dark skin our efforts are focused on superficial and medium depth peeling agents andtechniques.
Objective: To determine the effect of chemical peeling on ethnic (dark) skin in terms of safety and tolerance Methods: 25 women of Fitzpatrick Type V-VI between 16 and 45years. Of the 25 women, twelve had acne, five had acnescarring, six had melasma and two had acne and post inflammatory hyperpigmented scarring. All information regardingthe treatment and the complication which may occur as a result of the treatment were let known to the patients. Peelingprocedure was done according to Neostrata peeling protocol. All the patients were started with a 20% and the proceededto 35% to 50%.Peeling interval was 4 weeks. Pre and post peel photos were taken.
Results :The results show improvement in the patient's condition. Marked clearing of acne and improvement in melasmawas noted in the study group.
Conclusion: In the 18 month period there was no evidence of hyperpigmentation or scarring in the study group.
