ABSTRACT
Introduction: Constitutional infraorbital hyperchromia (commonly called under-eye circles) is a common dermatosis that is difficult to treat.
Objective: To evaluate the clinical improvement of constitutional infraorbital pigmentation resulting from the application of a series of five 10% thioglycolic acid gel peeling sessions.
Methods: Patients were administered five successive 10% thioglycolic acid gel peel sessions, in 15day intervals. In the first session, the product was left on for two minutes, with three minutes added in each subsequent session, culminating with 15 minutes of contact in the last session. Fifteen days after the last session, a satisfaction scale ranging from 0 (lack of improvement) to 10 (total improvement) was administered to the patients, to the dermatologist investigating the peelings, and to a blindevaluator medical doctor (a dermatologist that had not had taken part in the treatment sessions).
Results: Study subjects (n=10) were females aged 24-50.The average clinical satisfaction presented by the patients, the investigator, and the blind-evaluator were 7.8, 7.6 and 6.8, respectively, with no statistically significant differences among them (p=0.065).
Conclusion: The serial application of 10% thioglycolic acid gel peels is a safe, efficient, and costeffective treatment for constitutional infraorbital pigmentation.
