Dermal fillers are widely used in non-surgical aesthetic medicine. Their increasing popularity has brought questions regarding safety and awareness of their adverse effects. They are categorized as Class III medical devices and are injected into different layers of the skin or subcutaneous tissue to restore volume, smooth wrinkles, and reshape facial contours. Several types of fillers are used, the most common being hyaluronic acid fillers and biostimulatory fillers that boost collagen production. Technological developments have led to increased safety, better mechanical stability, and more consistent aesthetic results. Particular attention in this thesis was devoted to potential adverse effects, which range from transient local reactions to rarer but severe complications such as vascular occlusion, infection, or long-term tissue changes.
The aim of the research was to find out prevelance of the use of dermal fillers in Slovenia, why people decide to use them or avoid them, and how well they know the risks. According to the findings, around one-third of people, primarily those between the ages of 26 and 35, had previously used dermal fillers. Improving appearance was the most common reason for the procedure, and most commonly treated areas were the lips and nasolabial fold. Most users were satisfied with the results, although a quarter reported adverse effects, especially swelling and bruising at the injection site. Participants who had never used fillers most often stated that they were satisfied with their appearance, were afraid of complications, or did not like the idea of an unnatural look. Additionally, we conducted an interview with dermatologist Dr. Vesna Tlaker, who discussed the significance of clinical competence, selecting appropriate fillers, and early detection of complications. She also drew attention to procedures performed outside medical settings and the risks linked to unregistered products or self-injection. The findings show that dermal fillers are relatively well known in Slovenia, but the risks are still sometimes underestimated, which suggests that more awareness is needed.
