This paper examines the epidemiology, pathogenesis, and clinical and aesthetic consequences of acne and post-acne scars, as well as current options for their correction in the practice of a cosmetologist. The aim of the study is to systematize current data on the prevalence and risk factors of acne, clarify the role of hormonal, immune-inflammatory, and microbiome mechanisms, and substantiate an algorithmic approach to the treatment of post-acne scars and dyschromia. The methodological basis is the results of multicenter epidemiological projects, data from the Global Burden of Disease, clinical guidelines from specialized societies, and current reviews on chemical peels, laser and RF technologies, microneedling, subcision, and regenerative techniques (PRP/PRF, cellular technologies, fillers). The analysis demonstrates an increasing global burden of acne, a shift in incidence towards adult women, and the lack of a universal method for the treatment of post-acne scars. Personalized multi-step protocols combining fibrosis release, volume restoration, and skin surface remodeling demonstrate the highest clinical efficacy. Special attention is paid to scar prevention, reducing the risk of post-inflammatory hyperpigmentation in patients with high phototypes, and improving quality of life and psycho-emotional well-being. The need for interdisciplinary collaboration and monitoring of patients with acne and post-acne is emphasized.
