A double chin that is loose skin rather than fat is treated with smooth threads laid in a mesh under the skin to thicken it as they dissolve. Barbed threads draw the skin towards the angle of the jaw where it has loosened. One maker's page names under the chin with the under-eye area and the forehead among the uses of smooth threads; no US clearance names it and no series measures it, and we say so plainly. Placed by our doctor under local anaesthetic in 30 to 45 minutes at PDO Threads Clinic, 8 Exhibition Road, with the plan in writing at a free consultation.
What it does under the chin
The doctor tests whether your double chin is skin or fat by lifting it at the free consultation. Loose skin thickens and tightens over the months as collagen forms around the smooth threads, and the line from the chin to the neck sharpens. A fat pad is a fat-reduction question, which our sister clinics treat, with threads afterwards if the skin needs tightening. The result of smooth threads builds over months and fades over about a year as the threads dissolve.
The procedure and after
Local anaesthetic, smooth threads placed through a fine needle in a mesh under the chin, and barbed threads from behind the ear where a lift is planned. Swelling and tenderness for a week, a pull on turning the head for the first days, bruising in some. Sleep on your back with the head raised for about a week, no hard exercise for about a week and no massage for one to two weeks. The how it works page sets out each step.
Who it suits
Adults aged about 35 to 65 with loose skin under the chin and skin with some spring. The usual exclusions apply: pregnancy and breastfeeding, an active infection, a bleeding disorder or blood thinners that cannot be paused, an autoimmune disease without the doctor's advice first, keloid scarring. The neck page covers the neck below, and the full guide the rest.
