Combined use of microneedle radiofrequency lifting and injectable fillers based on hyaluronic acid in treatment of involutive changes in facial skin

Abstract

Combined procedures can be performed during one appointment to solve several problems for the patient. However, some treatments should be planned over several consecutive sessions to avoid complications and achieve optimal results. The purpose of our study was the scientific substantiation and development of an algorithm for the complex use of microneedle radiofrequency lifting and injection fillers based on hyaluronic acid in patients with involutive changes in the facial skin, taking into account the data of the pathomorphological research method. The patients were divided into three groups, depending on the treatment methods. In order to assess the effectiveness of therapy, a histological examination was carried out in five patients from each group, and a morphometric assessment was carried out. The histological picture and morphometric assessment of microslides from patients from different study groups indicate that microneedle RF lifting entails scar-type changes, which thins the thickness of the epidermis. However, the use of hyaluronic acid smoothes out these changes and leads to faster tissue restoration. At the same time, in the complex treatment group, better regenerative potential was noted than in the monotherapy groups, which is confirmed by the maximum value of basal epidermocytes per unit length.
