    PDO Thread Lift

    Non-surgical facial lifting using dissolvable threads that lift, tighten, and stimulate your body's own collagen — structure restored, naturally.

    What Are PDO Threads?

    PDO (polydioxanone) threads are medical-grade dissolvable sutures placed beneath the skin to lift sagging tissue and stimulate natural collagen production. They've been used safely in surgery for decades and are now one of the most effective non-surgical lifting treatments available.

    Unlike dermal fillers which restore volume, or Botox which relaxes muscles, PDO threads work mechanically — physically repositioning tissue whilst triggering a healing response that builds new collagen and elastin.

    The threads dissolve naturally over 6–9 months, but the structural collagen they stimulate continues to provide support for 12–24 months or longer. This makes PDO threads a uniquely effective bridge between injectable treatments and surgical intervention.

    Mono Threads vs Cog Threads

    Mono Threads

    • • Smooth, fine threads
    • • Stimulate collagen production
    • • Improve skin texture and tightness
    • • Ideal for skin quality improvement

    Cog Threads

    • • Barbed threads that grip tissue
    • • Provide immediate mechanical lift
    • • Best for jawline, mid-face, jowls
    • • Stronger, longer-lasting results

    Most thread lift treatments combine both types strategically — cog threads for structural lifting in areas like the jawline and cheeks, and mono threads for overall skin tightening and texture refinement.

    How the Procedure Works

    • Threads inserted using fine needles or cannulae
    • Threads positioned and adjusted for optimal lift

    PDO Thread Lift Before & After

    Results are visible immediately after treatment, with continued improvement over 2–3 months as collagen production increases and swelling settles. Individual results vary depending on age, skin quality, and the number of threads used.

    Results & Expectations

    Lifting is visible immediately after treatment. Over the following 2–3 months, results continue to improve as collagen production increases and the tissue adapts to its new position.

    The threads dissolve naturally over 6–9 months, but the collagen framework they create provides structural support for 12–24 months. Some patients see continued benefit for up to 3 years.

    Results depend on your age, skin quality, degree of laxity, and the number and type of threads used. Your doctor will give you a realistic assessment of what to expect during consultation.

    PDO threads are particularly effective when combined with other treatments such as dermal fillers for volume or Profhilo for skin hydration and quality.

    Aftercare & Recovery

    Most patients return to normal activities within 1–3 days. Mild swelling and bruising are common but resolve within a week.

    • Avoid strenuous exercise for 1–2 weeks
    • Sleep on your back for the first week
    • Do not massage or apply pressure to the treated area
    • Avoid facials, saunas, and extreme heat for 2 weeks
    • Apply ice if swelling or bruising occurs
    • A follow-up assessment is typically scheduled at 2 weeks

    Risks & Considerations

    PDO threads have been used safely in medicine for decades. However, like all procedures, there are potential risks that your doctor will discuss during consultation.

    • Mild swelling and bruising (common, resolves in 5–7 days)
    • Temporary tightness or pulling sensation
    • Dimpling at insertion points (usually temporary)
    • Infection (rare, mitigated by sterile technique)
    • Thread migration or palpability (rare with experienced injectors)

    These risks are significantly reduced when the procedure is performed by experienced, qualified doctors. At Cosmedocs, all thread lifts are doctor-led.

    Frequently Asked Questions

    PDO (polydioxanone) threads are medical-grade dissolvable sutures inserted beneath the skin. They physically lift sagging tissue and stimulate your body's natural collagen production. The threads dissolve over 6–9 months, but the collagen remodelling continues for up to 2–3 years.

    Mono threads are smooth threads that stimulate collagen and improve skin texture and tightness. Cog threads have barbs or hooks that grip the tissue and provide an immediate mechanical lift. Most thread lift treatments use cog threads for lifting areas like the jawline and mid-face, and mono threads for skin quality improvement.

    The threads dissolve over 6–9 months, but the collagen stimulation they trigger provides lasting structural improvement for 12–24 months. Some patients see continued benefit for up to 3 years. Results vary depending on age, skin quality, and the type of threads used.

    The procedure is performed under local anaesthetic, so discomfort is minimal during treatment. You may experience mild soreness, tightness, or tenderness for a few days afterwards, which is manageable with over-the-counter pain relief.

    Most patients return to work within 1–3 days. Full recovery takes about one week. During this time, you should avoid strenuous exercise, facial massage, and sleeping on your face. Mild swelling and bruising are common but resolve within 5–7 days.

    Ideal candidates are aged 30–65 with mild to moderate skin laxity who want facial lifting without surgery. PDO threads work best for patients with early signs of sagging around the jawline, mid-face, or neck. A consultation will determine your suitability.

    Yes. PDO threads are often combined with dermal fillers for volume restoration, Profhilo for skin quality, or Botox for dynamic lines. This combination approach — sometimes called a Liquid Facelift — provides comprehensive facial rejuvenation.

    Mono threads start from £350, cog threads from £850, and a full thread lift from £1,500. The exact cost depends on the number and type of threads required, which is determined during consultation.

    Considering a Thread Lift?

    A consultation with our doctors will assess your skin laxity and recommend whether threads, fillers, or a combination approach is right for you.

    PDO Thread Lift London — Non-Surgical Face Lift at Harley Street

    Cosmedocs offers doctor-led PDO thread lift treatments for non-surgical facial lifting and tightening at our Harley Street clinic in London. PDO threads, also known as polydioxanone threads, are medical-grade dissolvable sutures that physically lift sagging tissue whilst stimulating natural collagen production. Our GMC-registered doctors use premium cog threads and mono threads for jawline lifting, mid-face rejuvenation, and neck tightening. Over 1 million treatments performed since 2007.

    How PDO Thread Lifts Work

    PDO thread lift treatments use dissolvable medical threads inserted beneath the skin to reposition sagging tissue and stimulate collagen. Cog threads have barbs that grip tissue for immediate mechanical lifting, while mono threads stimulate collagen for skin tightening and texture improvement. Threads dissolve over 6–9 months but collagen remodelling continues for 12–24 months. PDO thread lift before and after results show visible lifting of jowls, jawline definition, and mid-face rejuvenation.

    PDO Thread Lift Suitability and Safety

    PDO threads are suitable for patients aged 30–65 with mild to moderate skin laxity. Thread face lift procedures are performed under local anaesthetic with minimal downtime. Recovery typically takes 3–7 days. PDO threads can be combined with dermal fillers, Profhilo, and Botox for comprehensive facial rejuvenation — known as a Liquid Facelift. Thread lift cost starts from £350 for mono threads and £850 for cog threads. Our aesthetics is invisible art — bold, natural, always your way.
