• Abstract:

  This article examines the role of chemical peels in modern dermatology, focusing on the treatment of acne vulgaris, its sequelae and emerging applications in onychopathologies. The results show that glycolic acid (GA) significantly outperforms salicylic acid (SA) in reducing post-inflammatory hyperpigmentation (PIH), with reductions of up to 75% after four sessions, while pyruvic acid (35%) improves quality of life by 68%, positively impacting psychosocial dimensions. Lactic acid (LA) stands out for its safety in sensitive phototypes, with a lower incidence of adverse effects. In onychopathologies, combined peels reduce nail thickness by 30%, although the lack of standardized protocols remains a challenge. In conclusion, efficacy requires rigorous personalization of the chemical agent, aligned with the skin characteristics and needs of the patients.
