Thread Lifting · Seomyeon, Busan
N-Cog thread lift in Busan Seomyeon
A bidirectional cog thread: barbs facing both ways along the whole length of a PDO thread, so one thread anchors at both ends and holds the tissue between them, with fewer entry points and a lift that works even on a face without much volume to grip. Quoted at the consultation by thread count, VAT included, by the doctor at Boom Dermatology, a skin clinic one minute from Seomyeon Station.

Start here — direct answer
What is N-Cog thread lift, and what does it do?
N-Cog
is a polydioxanone cog thread with its barbs cut in both directions
and spread evenly along the whole thread, rather than one direction from a single anchor. The practical difference is how it holds: a one-way thread pulls tissue toward its entry point and relies on that point to anchor; a bidirectional thread is placed through the drop and grips at both ends, so the tissue between is held from two sides, the entry can be a single small point in the hairline or temple, and the thread does not depend on a fat pad to bite into. That last point is why it is the cog thread for a leaner face
, the patient with a blurred jawline and little cheek volume whom a conventional barbed thread holds poorly, and for the neck and the lower jaw where tissue is thin.
At Boom Dermatology, N-Cog is the thread the doctor reaches for when a jawline or mid-face has dropped a little on a face without much to grip, when the patient wants the fewest entry points, or when a previous one-way thread slipped. It is quoted at the consultation by count; for heavier tissue the stronger MINT
or N-Fix
barb, for the longest hold Aptos, and for tissue too heavy for any thread, surgery, which we say plainly and refer.

Questions, answered properly
What does bidirectional actually change?
Where the hold comes from. A one-way cog thread pulls everything toward its anchor at the entry; if the tissue there is thin, the anchor is weak and the thread slips. A two-way thread grips at both ends and holds the tissue between them, so it works on a lean face and needs one entry instead of two. At Boom Dermatology that is the whole reason to choose it over a one-way thread, and it is not a reason to choose it for a heavy jowl.
I have a thin face. Will threads hold at all?
N-Cog is the cog thread most likely to, because it does not depend on a fat pad to bite into; mono threads and a collagen stimulator are the alternatives if the skin is thin as well as the face. The consultation pinches the tissue and says which applies, and a thin face is not sold a heavy barb.
How many entry points, and will they show?
One per vector, in the hairline or at the temple, a few millimetres each; they are covered by hair or make-up from day two and invisible by two weeks. Our Seomyeon skin clinic marks them with you upright so you can see where they go before anything starts.
How long does N-Cog last?
Nine to fifteen months of lift by the barb, then the collagen along the track keeps the tissue a little firmer for a year after. Repeat when you want the lift back; many patients alternate with HIFU between.
N-Cog or MINT for my jawline?
N-Cog for a lean jawline with a little drop and a wish for the fewest entries; MINT for a jowl with weight to it, where the moulded barb's grip matters more than the entry count. The doctor at Boom Dermatology in Busan says which your jawline is, and writes the quote for that one.
The doctor says whether N-Cog thread lift fits your face, names the thread count and the vectors, and writes the VAT-included quote before you book a flight to Busan.
