Introduction and purpose: For all skin types, micro-needle radiofrequency (FMR) can be a safe and effective aesthetic medicine procedure for the treatment of various dermatological and aesthetic conditions. The aim of the study is to present the mechanism of action and assess safety, treatment efficacy, and possible side effects on the basis of a review of the scientific literature. Description of the state of knowledge: FMR uses micro-needles to penetrate the skin to a depth of up to 4.5 mm and deliver radiofrequency current in a fractional manner, producing the controlled fractions of micro-injuries in the dermis, inducing neocollagenesis, neoelastinogenesis, and angiogenesis. FMR has a wide range of positive effects such as skin rejuvenation, skin tightening, facial and body scar remodeling, and hair growth through transdermal collagen induction. Summary: Increasingly, patients are looking for minimally invasive methods of skin tightening and fat remodeling. In response, Aesthetic Medicine has proposed a combination of two techniques, micro-needling and radiofrequency. As more and more studies are showing the effectiveness and efficiency of this procedure, also emphasizing its safety, minimal risk of serious side effects, and ease of use, micro-needle radiofrequency is being proposed as an attractive answer to people's desires for a less invasive method of skin rejuvenation. However, further research in this area is needed to optimize the parameters of the treatment to achieve the best results.

Introduction and purpose: Varicose veins of the lower limbs are quite common and common disease. Their presence may be associated with the occurrence of a number of symptoms that negatively affect the quality and comfort of life, such as swelling, leg pain and cosmetic defect.The aim of the study is to review the available literature and articles available in the PubMed database in order to learn about the pathophysiology of varicose veins, methods of diagnosis and the most popular methods of their treatment. State of the knowledge: Varicose veins are described as fusiform dilatation of superficial veins with accompanying elongation and characteristic twisting. The main cause of their formation is insufficiency of the venous valve apparatus. Genetic and individual factors such as sex, age, and excessive body weight also have an impact. The diagnosis is based primarily on the physical examination of the patient and the Doppler ultrasound examination of the veins. Management options for varicose veins range from conservative management including pharmacotherapy to invasive and surgical methods, each of which has both advantages and disadvantages. Summary: Making a diagnosis of varicose veins usually does not cause many difficulties. There is no one-size-fits-all treatment method. When choosing it, many aspects should be taken into account, such as the patient's preferences, severity of disease symptoms, and the patient's general condition.
