PDO Thread Types Explained for Walnut Creek Patients

Smooth PDO threads, also called mono threads, are single polydioxanone filaments without any barbs or texturing. They cannot lift tissue mechanically, but their value lies in collagen stimulation. When placed in a mesh or cross-hatch pattern beneath the skin, each thread creates a line of controlled inflammation that activates fibroblasts and triggers new collagen production along its entire length. For Walnut Creek patients, smooth threads are ideal for improving skin quality in areas not suited for barbed lifting: forehead fine lines, under-eye crepiness, neck skin tightening, lip lines, and general skin rejuvenation. The treatment involves placing 10-20 smooth threads in a grid pattern across the target area. Over the following 2-6 months, the collagen response firms, tightens, and improves the texture of the treated skin.

Barbed PDO threads, also called cog threads, feature small hooks or barbs molded along their length. These barbs grip tissue when the thread is inserted, allowing the provider to physically reposition sagging skin by applying upward tension. Barbed threads are the workhorse of thread lift procedures and the only thread type that provides genuine mechanical lifting. Barbed threads are used for mid-face lifting to reposition descended cheeks, jawline definition to lift jowling tissue, brow elevation to open hooded eyes, and neck lifting for mild to moderate laxity. The barbs come in different configurations: unidirectional barbs face one way for maximum pull in a single direction, while bidirectional barbs face both ways from the center for anchoring in the middle of the thread.

Twist or screw PDO threads are wound around the insertion needle in a spiral pattern. When deployed, the coiled shape occupies more space beneath the skin than a straight thread, creating a subtle volumizing effect. They combine volume enhancement with collagen stimulation, making them useful for areas that need both plumping and skin quality improvement. Common applications for twist threads include nasolabial fold softening, marionette line areas, hollow temples, and areas of mild facial volume loss. They bridge the gap between threads and dermal fillers, providing modest volume without injectable gel. At A Touch Above MedSpa, your provider may combine all three thread types in a single session to address lifting, tightening, and volume in different facial zones.

Most comprehensive thread treatments use a combination of thread types, each placed where it performs best. A typical full-face treatment might include 6-10 barbed threads for mid-face and jawline lifting, 4-8 smooth threads for neck and forehead skin quality, and 2-4 twist threads for nasolabial fold and under-eye volume. This combination addresses all aspects of facial aging in a single session. During your consultation at A Touch Above MedSpa (accessible from Walnut Creek), your provider evaluates which thread types and quantities will best address your specific concerns. The treatment plan is customized to your anatomy, not a one-size-fits-all protocol. This personalized approach ensures optimal results from the minimum number of threads needed.
