BTX-A( Botulinum Toxin Type A) is a purified protein that is used to relax the facial muscles which cause wrinkles. BTX-A reduces the activity of these muscles, hence reducing the appearance of facial lines and wrinkles.
BTX-A can be used on patients with a square jaw line, thereby reducing the size of the jaw muscles. This results in a smaller, V-shaped jawline.
BTX-A can last from three to four months on average with follow-up and maintenance treatments two to three times a year. Additional treatments can actually prolong the smoothening effects so that visits to your doctor gradually become less frequent.
