The cosmetic form of Botulinum Toxin is a popular injectable treatment in Singapore that relaxes the facial muscles to smooth out fine lines and wrinkles, such as the “11” frown lines, crow’s feet, wrinkles around the lips (smoker’s lines) and marionette lines. When injected in the masseter muscle, it is also known to cosmetically slim the jawline and balance facial proportions while relieving clenching or teeth grinding.
