It is commonly associated with obesity, diabetes, and insulin resistance. Although the primary treatment is correcting the underlying disorders, many aesthetic modalities have been established to improve appearance owing to cosmetic concerns.<\/jats:p><\/jats:sec><jats:sec><jats:title>Aims<\/jats:title><jats:p>We aimed to compare and investigate the effectiveness and side effects of tretinoin 0.05% and glycolic acid 70% in treating acanthosis nigricans lesions of the axillary and neck area.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>This single\u2010blinded, randomized trial recruited patients with neck or axillary involvement. Each patient was randomized to use cream tretinoin 0.05% every other night on one side, while the other side was treated with glycolic acid 70%, which was applied every 2\u2009weeks at the clinic for four consecutive sessions. The study duration was 8\u2009weeks, and patients were evaluated every 2\u2009weeks based on their response to treatment, satisfaction, and side effects.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Thirty patients, including 14 with neck lesions and 16 with axillary lesions, were included.
