Mid-face wrinkles are often the result of the natural aging process and involve sagging of the facial structures and loss of subcutaneous fat. A number of treatment options are available including surgical procedures, fat transfer, and injection of various dermal fillers. Each of these options having varying levels of effectiveness and durability and, as with any medical procedure have safety risks. Barbed polydioxanone (PDO) sutures are absorbable threads with barbed sutures along the surface indicated for the treatment of mid-face wrinkles.

PDO sutures have long been used for tissue approximation and have been shown to be safe to use. However, there have been no sutures approved in the US for mid-face wrinkle reduction indication. Therefore, we wish to conduct this prospective study in order to observe safety and effectiveness of PDO suture use in reducing mid-face wrinkles.


Rejuva Medical Aesthetics is recruiting participants for a clinical research study to evaluate the safety and effectiveness of barbed PDO sutures for the temporary treatment of mid-face wrinkles.

Purpose of the Study:

The purpose of this study is to evaluate the safety and effectiveness polydioxanone (PDO) dissolvable threads for the temporary treatment of mid-face wrinkles.
