Service Definition
Polydioxanone (PDO) threads are sterile, absorbable sutures made from the same material used in cardiovascular surgery. In aesthetic medicine, PDO threads are inserted beneath the skin using fine cannulas or needles to mechanically lift and reposition ptotic tissue, while simultaneously triggering a foreign-body fibrotic response that stimulates new collagen deposition around each thread. The threads dissolve within 4–6 months; the collagen scaffold they create persists significantly longer.
Two Types of PDO Threads: Lift and Smooth
PDO threads come in two primary categories. Barbed (cog) threads carry directional hooks that mechanically grip and reposition sagging tissue — used for jawline lifting, brow elevation, and midface repositioning. Smooth (mono) threads have no barbs and are placed in grids or patterns to stimulate diffuse collagen production, improving skin texture and laxity without significant repositioning.
Younger You Aesthetics uses both thread types depending on your anatomy, skin laxity degree, and aesthetic goals. Even if you believe your concerns are too mild for surgical options but too significant for injectables alone, PDO threads fill a meaningful treatment gap.
