Stimulation of collagenesis by poly-L-lactic acid (PLLA) and -glycolide polymer (PLGA)-containing absorbable suspension suture and parallel sustained clinical benefit.

Absorbable suspension sutures stimulate collagen in areas immediately adjacent to the path of the PLLA/PLGA monofilament and cones, providing mechanistic support for improvement in appearance observed in clinical studies. This neocollagenesis, coupled with repositioning by the suture's cones, makes absorbable suspension sutures a valuable tool for patients seeking facial rejuvenation.
