PrecisionTx is a minimally invasive laser liposuction procedure used to tighten the skin on the neck and jawline. It’s also used to ablate the sweat glands in the armpit to treat excessive sweating (hyperhidrosis). A series of 3 small incisions are usually made below the chin. A very thin laser tube is inserted through the incisions to deliver laser energy to the areas being treated and to liquefy excess fat and heat loose or sagging skin from within. The laser energy causes tissues to contract and promote new collagen growth for thicker skin.
