Botox Masseter Reduction

I've been going to Dr.Edmund Kwan's practice in NYC for many years now. From Botox injection to facial surgery. I've come to an understanding that Dr.Kwan is the best at what he does around my area. Botox injections were always painless and on multiple spots along the jawline. It usually lasts for about 3-6 months depends on the patient. But it shows a significant reduction, a slimmer jaw-line after about two weeks post injection.
