Thread Lift: Methods, Effects, Costs and Risks

A thread lift is a minimally invasive facial tightening procedure in which self-dissolving PDO, PLLA or PCL threads are placed under the skin to lift tissue. As a gentle alternative to a surgical facelift, it achieves noticeable tightening and lifting without major incisions, extended downtime or the risks of general anaesthesia. The absorbable specialty polymers reposition lax facial and neck structures while simultaneously stimulating the body's own collagen production — a medically sound principle gaining increasing significance in aesthetic medicine worldwide.

What Is a Thread Lift?

In a thread lift, fine threads made of bioresorbable materials are introduced into the subcutaneous tissue of the face or neck using special cannulas or needles under local anaesthesia. Depending on the thread type, they work through two mechanisms:

Mechanical lifting: Barbed threads (cog threads) anchor in the tissue and immediately reposition it into an elevated position.
Biostimulation: All thread types trigger a controlled foreign-body response stimulating fibroblasts to produce new collagen and elastin around the thread.

Thread Materials: PDO, PLLA and PCL

PDO (Polydioxanone) Threads

PDO is the most widely used thread material with a long track record in surgical sutures. The threads dissolve within approximately 6 months. Collagen stimulation continues for several months after dissolution, extending the visible effect to 12–18 months. PDO threads are available in smooth, twisted and barbed (cog) variants.

PLLA (Poly-L-Lactic Acid) Threads

PLLA threads dissolve more slowly (over approximately 12–18 months), producing a more intense and prolonged biostimulation effect. They are particularly suited for patients seeking strong collagen regeneration, with visible results lasting up to 24 months.

PCL (Polycaprolactone) Threads

PCL has the slowest resorption rate (18–24 months). Combined with PLLA in hybrid threads, PCL provides the longest-lasting collagen stimulation available in absorbable threads. Results may persist for 2–3 years.

Thread Types and Their Applications

Thread Type	Mechanism	Best For
Smooth / mono threads	Biostimulation, mesh scaffold	Fine lines, skin quality improvement
Twisted / screw threads	Volume and biostimulation	Cheek volume, skin texture
Barbed / cog threads	Mechanical lifting and biostimulation	Jowls, brows, midface, neck
3D spring threads	Combined lifting and volume	Deep tissue repositioning

Treatable Areas

Thread lifts can be applied to a wide range of facial and body areas:

Cheeks and midface (lifting of the malar fat pad)
Jawline definition and reduction of jowls
Neck and platysmal bands
Eyebrow lifting
Nasolabial folds and marionette lines
Brow and forehead area
Décolleté and body areas (arms, knees, abdomen)

The Procedure

A thread lift is performed under local anaesthesia in the practice and takes 30–90 minutes depending on the number of threads and areas treated:

Disinfection and marking of insertion points
Local anaesthesia at insertion and exit points
Introduction of threads via fine cannulas or needles into the correct tissue layer
Activation of cog threads by gentle traction to achieve the lifting effect
Trimming of excess thread ends; closure of insertion points

The result is immediately visible; the full effect develops over 4–8 weeks as biostimulation builds up.

Longevity of Thread Lifts

Thread Material	Resorption	Visible Result Duration
PDO	approx. 6 months	12–18 months
PLLA	12–18 months	18–24 months
PCL / PCL-PLLA hybrid	18–24 months	24–36 months

Results depend on skin quality, age, number of threads placed and individual collagen response. Repeat treatments extend and maintain the effect.

Thread Lift vs. Surgical Facelift

Criterion	Thread Lift	Surgical Facelift
Invasiveness	Minimally invasive	Surgical
Anaesthesia	Local	General or sedation
Downtime	2–5 days	2–4 weeks
Visible result	Immediate, full after 4–8 weeks	After 4–6 weeks
Longevity	1–3 years	7–12 years
Degree of correction	Mild to moderate	Moderate to significant
Scars	Micro-puncture only	Visible (ear and hairline)

Risks and Complications

Thread lifts are generally safe when performed by experienced practitioners, but complications can occur:

Common and temporary:

Swelling, bruising and mild pain at insertion sites (resolves within 1–2 weeks)
Dimpling or skin irregularities (usually self-resolving within weeks)
Temporary numbness along the thread tract

Less common:

Palpable or visible threads if placed too superficially
Thread migration or extrusion through the skin
Asymmetric result requiring correction
Infection at insertion sites

Rare but serious:

Damage to facial nerve branches causing motor weakness
Vascular injury (rare with proper technique)
Persistent granuloma formation around thread remnants

Costs of a Thread Lift

Treatment Area	Approximate Cost
Single area (e.g. brow lift)	from £400–£800
Midface and cheek lift	from £800–£1,500
Full face thread lift	from £1,500–£3,000
Neck and jawline	from £700–£1,400
Full face and neck combined	from £2,000–£4,500

Prices vary depending on the number of threads used, thread type (PDO/PLLA/PCL), the practitioner's experience and clinic location. Thread lift is not covered by health insurance as an elective aesthetic procedure. A thorough consultation — including assessment of skin laxity and suitability for thread lifting versus surgical alternatives — is strongly recommended before treatment.
