The tail of the brow and the outer corner of the upper lid are lifted with barbed threads passed from the hairline down to the brow and drawn back. People call it the fox eye when the lift is angled upwards and outwards. Two published series treated it, 29 patients in 2025 and 15 in 2023 with a lifting thread on the brows and upper eyelids; no US clearance names the brow, and we say so. Placed by our doctor under local anaesthetic in about 30 to 45 minutes at PDO Threads Clinic, 8 Exhibition Road, with the plan in writing at a free consultation.
What it does at the brow
A brow that has settled lower with age, or a heavy outer upper lid, lifts as the threads hold the tissue higher, and the eye looks more open. The fox eye is the same lift angled towards the temple. In the 2025 series, 26 of 29 patients were satisfied or very satisfied. A heavy, dropped brow is more than threads lift, and the doctor says so at the free consultation; the lift fades over about a year as the threads dissolve.
The procedure and after
Local anaesthetic along each thread's path and small entry points in the hairline at the temple. Each thread is passed through a needle or a blunt cannula down to the brow, drawn back to engage the barbs, trimmed and buried, one to two a side in our practice. Swelling and tightness at the temple for a week or two, a pull on raising the brows 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 or facials for one to two weeks. The how it works page sets out each step.
Who it suits
Adults with a brow that has settled or a heavy outer upper lid and skin with some spring, not very thin skin at the temple, which would show the threads. 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 forehead page covers the forehead lines, and the full guide the rest.
