How does a contour thread lift work?

Not well. I use to perform these but no longer employ them other than for rare circumstances where patients are not surgical candidates and require mild short term correction.
Silhouette Instalift. There are many different types of thread lifts. The Silhouette Instalift is, unique in that it is, an absorbable product that stimulates your own collagen. The thread has cones attached that when placed properly in the fat of the cheek lifts, supports and holds the overlying skin. It stimulates your own collagen to add volume & shape to your face and neck.
