PDO threads, short for Polydioxanone threads, are absorbable sutures widely used in the field of medical aesthetics.
Originally developed for cardiac surgery due to their excellent biocompatibility and absorbability, PDO threads have evolved into a popular choice in cosmetic procedures.
Here is a detailed overview of PDO threads:
- Origin and Applications
Origin: PDO threads were initially used as sutures in cardiac surgery. Their biocompatibility and complete absorption in the body led to their adaptation for cosmetic purposes.
Applications: They are primarily used for facial lifting, wrinkle reduction, and contouring. By stimulating the regeneration of collagen in the skin, PDO threads help tighten the skin and improve wrinkles.
- Composition and Characteristics
Composition: PDO threads are primarily composed of Polydioxanone, a fully absorbable synthetic polymer.
Characteristics: These threads are smooth and flexible, allowing easy insertion into the superficial layers of the skin. They naturally dissolve and are absorbed within the body due to their metabolic breakdown, ensuring safety and no long-term side effects.
- Mechanism of Action
Once implanted, PDO threads gradually dissolve and are absorbed by the body. Over a period of 6-8 months, they continue to stimulate the skin and fascial layers, reorganizing stiff or sagging muscle tissues.
Additionally, PDO threads activate fibroblasts in the skin, promoting the regeneration of collagen, thereby enhancing skin elasticity and tightness.
