Application of a series of trichloroacetic acid treatments and its effect on sebum levels and acne scars: a case report.

Background: Acne vulgaris is a condition that most often appears during adolescence and can last from a few to over a dozen years. Unpleasant remnants of acne include post-inflammatory hyperpigmentation and acne scars, which often result in a reduced quality of life and can interfere with sufferers’ ability to function in society. Aim of the study: Assess the effectiveness of trichloroacetic acid (TCA) in reducing skin sebum levels (oiling) and smoothing acne scars. Case report: A 35-year-old female reported excessive oiliness of the skin and acne scars on both cheeks. Before and after TCA treatment, sebum levels were measured on the surface of the skin using a Sebumeter®. In addition, the cheek scars were graded using the Goodman and Baron scale. Conclusion: After a series of five treatments with TCA, there was a large reduction in sebum on the epidermal surface, and acne scars were reduced on both cheeks.
