Fox Eye Thread Lift
Six to twelve months of subtle lift, then it is gone. Visible thread extrusion, dimpling and puckering are common enough to be the main reason it fell out of favour.
Also called: thread lift · fox eyes · pdo threads · cat eye lift
Verdict — mixed
Real in part — the claim outruns what it actually does.
Evidence grade C
Mechanistic plausibility, small studies, or observational data. Suggestive, not established.
Mechanism
Barbed polydioxanone or polylactic threads are passed subcutaneously and anchored to lift tissue mechanically; the polymer hydrolyses over months, with some collagen deposition along the tract.

The full read
Meta-analyses support a real but small and short-lived lift — the honest comparison is not with a brow lift but with a good month of sleep. The complication list is unusually visible for a 'lunchtime procedure': thread extrusion through the skin, palpable or visible puckering, asymmetry, and infection along the tract. The temple placement popularised for the fox-eye look sits near the frontal branch of the facial nerve. Where a brow genuinely needs lifting, a surgical brow lift lasts and a well-placed `botox-upper-face` chemical brow lift costs a fraction. The trend peaked around 2020 and practitioner enthusiasm has cooled for reasons worth noticing.
