PDO (Polydioxanone) Threads, also known as Nova Threads, are a type of minimally invasive cosmetic procedure used for skin rejuvenation and lifting. These threads are made of a biocompatible material called PDO, which is commonly used in medical sutures.

1. Procedure: During the procedure, very fine, dissolvable PDO threads are inserted into the skin using a specialized needle or cannula. The threads are strategically placed in the target areas to lift and tighten the skin.

2. Types of Threads: PDO Threads come in various types and designs, each serving a specific purpose. Some threads are smooth, while others have barbs or cogs along their length to provide more lifting and anchoring effects.

3. Collagen Stimulation: PDO Threads stimulate collagen production in the skin. The threads create a supportive structure that triggers the body's natural healing response, leading to the formation of new collagen fibers. This collagen production helps improve skin elasticity, texture, and firmness over time.

4. Skin Lifting and Tightening: PDO Threads provide an immediate lifting effect by physically repositioning sagging or loose skin. The threads create tension and lift the targeted areas, resulting in a more youthful and rejuvenated appearance. The lifting effect continues as the threads stimulate collagen production, gradually improving the skin's firmness and tightness.

5. Dissolvability and Duration: PDO Threads are made to be absorbable, meaning they are naturally broken down by the body over time. The dissolving process usually takes several months. However, the collagen production stimulated by the threads can last longer, contributing to the overall improvement in skin quality.

6. Treatment Areas: PDO Threads can be used to address various areas of the face, including the forehead, eyebrows, temples, cheeks, jowls, jawline, and neck. They can help improve facial contours, reduce the appearance of wrinkles, and provide a lifting effect in specific areas.
