PCA threads are the newest threads and are bio-absorbable, monofilament suspension threads of synthetic origin (caprolactone).
They work by regenerating collagen over a longer time than PDO and PLA threads. They leave behind a collagen structure that provides support for the skin, tightens the skin and prevents it from sagging.
Due to the fibrotic reaction caused by the threads, the lifting and stretching action will continue even after the threads have been resorbed. The process of thread breakdown produces molecules of small molecular weight which subsequently induce the production of collagen and Hyaluronic acid by the skin.
The resulting skin is more moisturized, revitalized and firm with a long lasting result.
