PDO PCL THREADS

https://www.eastcosmetics.com/products/pdo-pcl-threads/

PDO PCL Threads are unique in that they also contain polycaprolactone (PCL), which is another biodegradable material that stimulates the production of collagen and elastin in the skin. When the PCL PDO Threads are inserted into the skin, they create a mesh-like structure that supports the skin and helps to lift and tighten sagging areas.
