Happy Lift has a unique patented line of sutures. Unlike conventional sutures which are smooth, all Happy LiftTM threads have tiny barbs (or cogs) with a special design in terms of their length, density and angling meant to carry our both a lifting and a revitalizing effect. Once inserted into the sub-dermis, the barbs gather the skin producing fibrosis necessary to provide new support scaffolding for the soft facial tissues, that lift and hold them in place. As a result, a refreshed look and a better facial contour are visible just immediately after the operation.
