Background. The arsenal of physical methods for correcting pathological skin scars is quickly replenished, but the results of their use are often unsatisfactory. An inadequate approach to therapy, without taking into account the evaluation of their effectiveness, leads to relapses and increased growth of scar tissue or the absence of a clinically significant effect of many of them and requires strict scientific evidence in the course of benign scientific studies.

Aims: Comprehensive (qualitative, quantitative, structural) analysis of evidence-based research in electronic evidence-based research databases (PEDro, PubMed, e-Library) and systematic review databases (Cochrane Library) for the period from 2000 to 2020.

The clinical effects and suggested mechanisms of action of currently proven therapeutic physical factors in the treatment of patients with coronary heart disease are considered in detail. The most studied of the physical methods with proven effects are high-intensity laser technologies of high-intensity laser therapy (47%), fractional radiofrequency therapy (14%), microneedling (9%) and microdermabrasion (8%), which cause the most pronounced remodeling of the extracellular matrix of the skin in the area of scars.

Conclusion. It is necessary to regularly generalize and analyze existing evidence-based studies, as well as perform new high-quality randomized controlled clinical trials to study the impact of physical correction methods on post-acne scars, which serve as the basis for developing clinical recommendations.
