PDO (Polydioxanone) threads are dissolvable sutures that are strategically inserted into the skin to lift and tighten sagging areas. The threads provide an immediate lifting effect while also stimulating the body’s natural production of collagen, which helps improve skin firmness and elasticity. PDO threads are a safe and effective way to address loose or sagging skin in areas such as the cheeks, jawline, neck, and even brows. Over time, as the threads dissolve, the skin continues to firm and rejuvenate, leaving you with long-lasting, natural-looking results.
