Masseter slimming is a highly effective non-surgical treatment that reshapes and slims the lower face by reducing the size of the masseter (jaw) muscles. Using anti-wrinkle injections placed directly into the masseter muscles, we gradually reduce their bulk over several weeks, resulting in a slimmer, more V-shaped jawline. Beyond its cosmetic benefits, this treatment also provides relief for patients who suffer from teeth grinding (bruxism), jaw clenching and associated tension headaches. The procedure is quick and comfortable, with results becoming increasingly visible over 4–6 weeks as the muscles gradually reduce in size. Effects typically last 4–6 months, and regular treatments can lead to longer-lasting results.
