The fastest and most effective way to lose a double chin is through liposuction. Liposuction can completely and effectively remove the double chin, reduce the effect of gravity, reduce facial sagging, and the photoelectric stimulation of the subcutaneous tissue by the liposuction needle and laser can induce the production of fibroblasts, rebuild blood flow to the skin and subcutaneous blood flow will increase, restore the elasticity of the skin, and induce skin contraction. The procedure uses a needle in the back side of the chin and a superficial suction of fat. It is suitable for patients with more fat in the chin. The surgery takes about 40 minutes and the swelling usually subsides in 5 to 7 days after surgery, with a basic recovery in half a month. It is recommended to use an elastic mask for 3 months to 6 months after surgery.
