There are several types of PDO threads used in aesthetic medicine, each with its own unique properties and benefits.
- Barbed Threads: These threads contain barbs that engage the skin tissue for lifting, which allows for accurate and precise results. They come with either a sharp needle tip or a blunt-tipped cannula. The use of a cannula reduces the risk of puncturing blood vessels or nerves and is therefore the most common choice for thread lifting.
- Molded Barb Threads: Similar to barbed threads, molded barb threads have barbs for tissue engagement but with a higher slippage threshold. This makes it less likely for the barbs to disengage, but also more difficult to remove if needed.
- Smooth/Monofilament Threads: Unlike barbed threads, smooth threads don’t have barbs. They are delivered on a needle applicator and are commonly used for collagen induction, which helps improve the appearance of thin or crepey skin.
- Twist/Corked/Torpedo Threads: Twist threads are spiral-oriented around the needle applicator and are mainly used for collagen stimulation, but can also be used to soften fine lines.”
