PDO threads are an effective cosmetic technique that lifts and tightens sagging skin tissues by inducing collagen production. It involves the implantation of fine, absorbable polydioxanone threads (similar to those used in medical suturing) into the subcutaneous layer of the skin using small needles.

 

These threads remain implanted in the skin causing micro-injuries that stimulate collagen synthesis and tissue contraction. After six months, the threads will be absorbed into the body leaving new collagen in their place.
