PDO threading is a cosmetic procedure that uses small, absorbable threads to lift and tighten the skin. The threads are inserted into the skin using a needle and then lifted, providing an immediate lifting effect. Over time, the threads stimulate collagen production, which helps to further tighten and firm the skin. PDO threading can be used to treat a variety of areas, including the face, neck, and body. The procedure is minimally invasive and requires little downtime, making it a popular option for those looking to improve their appearance without undergoing surgery.
