Gold Thread medical technology is used in skin rejuvenation. The technique involves implantation of a thin gold filament into the sub dermal skin. After being introduced into the skin, gold stimulates increases production of collagen and fibroblasts in response to the presence of a foreign substance. Collagen sleeves are formed around the implanted threads. New tissue formation is stimulated and increased metabolism and blood flow occurs in the treated areas, which results in skin rejuvenation. Results are noticeable shortly after the treatment and complete results usually are achieved by one year postoperatively. Patients are able to go back to their normal life immediately after the procedure.

There is evidence that facial gold implantation for esthetic purposes was used in ancient Egypt. The Gold Thread procedure was commercialized in Europe in the late 1970-ies. Other names used for the procedure are: Gold Filament, Gold Lift; Remaillage (Mending of Meshes) - France; Gold Reinforcement – Russia; and Gold Silk – China.
