There are several types of PDO threads on the market and there are several different types of PDO threads including barbed, twisted, cogged, etc. Different types of PDO thread can be used depending on the patient, location and goals to be acheived. Several brands now have FDA approval. Silhouette threads are made of PLA (threads) and PLGA (cones) and are FDA approved. I use Silhouette threads in the midface, neck and ocassionally other locations depending on patients skin qualities and cosmetic goals. Good results can be acheived with both types of threads depending on the provider and patient. Please see a board certified dermatologist or plastic surgeon for a consultation.
