Abstract
Atrophic post-acne scars are severe manifestations of the post-acne symptom complex, which occur as a result of inflammation due to the loss of collagen fibers and subcutaneous fat during the healing of inflammatory acne elements. The incidence of post-acne scars has been little studied, but according to some authors, about 90 % of patients with severe and moderate acne suffer from them. The aim of the study was to study the effect of the combined use of IPL- and PRP-therapy, fractional microneedle radiofrequency therapy and PRP-therapy, as well as microneedling of autologous plasma with cells on the clinical symptoms of atrophic skin scars, taking into account the duration of the pathological process, based on the dynamics of the indicators of the Manchester Assessment Scale of Scar Deformations. Complex methods showed higher efficiency than the use of hardware techniques in relation to all clinical signs of atrophic scars.
