Cog thread

| Also known as | barbed thread, bidirectional PDO cog

Cog threads have barbs (cut, molded, or helical) that catch subcutaneous tissue so the operator can hitch a vector — midface, jaw, brow. This is the “lift” in thread lift, as opposed to mono thread collagen mesh. Bidirectional barbs are common; press-molded 360° barbs are the MINT lift pitch. 4D/6D/8D/9D on a pouch usually means how many rows of barbs, not nine operations.
Plane and vector decide the result (cheek hitch vs dimple). Migration, visibility, and extrusion are failure modes. Tying paired cogs at one entry is a published trick against migration.

The hitch this encyclopedia prefers for mild midface descent, including a hanging nasolabial fold, when a facelift is not the job. See that fold page.
