PDO threads are made of Polydioxanone, which is a biodegradable polymer commonly used to make dissolvable sutures. These threads are used to tighten and lift the skin as well as accentuate certain features of the face. These threads are placed under the skin in specific areas and they come in three different types, each designed to treat different patient concerns. PDO Mono threads are smooth, straight, single threads that are used to increase collagen production to rejuvenate the skin and also to add structure to create shape. They work extremely well for adding definition to the lip line and can be used to create a Cupid’s Bow without increasing the size of the upper lip.
This is a great option for patients who would like to accentuate the features of their lips without increasing their size and outward protrusion the way dermal fillers do. They can also be placed under the skin to fill in vertical fine lines around the mouth, often referred to as pucker lines. PDO Cog threads have tiny barbs on them that grab the skin from the inside to provide support and lift parts of the face. These are commonly used to lift the cheeks or raise the arches of the eyebrows. Lastly, PDO Screw threads are either one or two intertwined threads in a corkscrew shape, and these are best for restoring volume in sunken parts of the face like the cheeks or temples.
PDO threads are a great alternative to a surgical facelift as they are cheaper and less invasive. These threads are versatile and can be used for many different concerns. Common areas treated include deep forehead creases, crows feet around the eyes, deep glabellar lines, the cheeks, jawline, and around the mouth and lip lines. The threads dissolve completely over a six month period of time and collagen and elastin fibers take their place holding the desired shape for an average of two years.
