%X Acanthosis nigricans (AN), with an estimated prevalence of 19.4% in the U.S., presents as hyperpigmented, velvety plaques in intertriginous regions. Acanthosis Nigricans negatively affects psychological well-being and particularly impacts skin of color individuals. Addressing the underlying cause of acanthosis nigricans, as current guidelines recommend, is often challenging. This highlights the importance of skin directed treatment for acanthosis nigricans. This systematic review evaluated topical, laser, and oral treatments for acanthosis nigricans and provides evidence-based recommendations for clinical use. Adhering to PRISMA guidelines, we evaluated 19 clinical trials investigating topical, oral, and laser interventions for acanthosis nigricans. Oxford Centre for Evidence-Based Medicine guidelines were used to make clinical recommendations. We strongly recommend topical tretinoin (grade A) and endorse the appropriate use of adapalene gel, urea cream, and fractional carbon dioxide laser therapy (grade B). Further research is essential to enhance our understanding of alternative treatments to determine additional evidence-based recommendations. This review aims to guide clinicians in managing acanthosis nigricans, especially when direct treatment of underlying conditions is impractical.
