Atrophic scars are a common pathology that can have a negative impact on the patient’s quality of life. Methods for correcting atrophic scars include chemical peels, dermabrasion, ablative or non-ablative laser resurfacing, filler insertion, and surgical techniques. Depending on the type and severity of the scar, an individual approach is required to obtain satisfactory results. Material and methods. The study included 32 patients with atrophic scars. Depending on the therapy, the patients were divided into two groups in which they received microneedle radiofrequency therapy or fractional photothermolysis. The effectiveness of the methods of therapy was assessed using laser doppler fluometry and ultrasound scanning. Research results. The RF microneedle method and fractional photothermolysis have a positive effect on the epidermal-dermal structure of the skin, which is expressed in the approximation of the acoustic density and thickness of the epidermis and dermis to normal values, and also improve microcirculation. When analyzing the results of correction of atrophic scars, more pronounced positive dynamics was observed after the application of RF microneedles.

Atrophic scars after acne are a widespread condition that can have a negative impact on the patient’s quality of life. Correction methods for acne scars include chemical peeling, dermabrasion, ablative or non-ablative laser resurfacing, filler insertion and surgical techniques. Depending on the type and severity of the scar, an individual approach is required to obtain satisfactory results.Material and methods. Under observation were 61 patients with various manifestations of post-acne. Among them 21 (34.44 %) men and 40 (65.57 %) women. Depending on the therapy, the patients were divided into two groups and two subgroups depending on the type of scar. Efficiency was evaluated using ultrasound scanning.Results. The RF microneedle method and fractional photothermolysis have a positive effect on the epidermo-dermal structure of the skin, which is expressed in the approximation of the acoustic density and thickness of the epidermis and dermis to normal values. The most pronounced positive effect in both methods was noted in the correction of post-acne hypertrophic scars. When analyzing the results of correction of atrophic scars, more pronounced positive dynamics was observed after the use of RF microneedles.
