PDO Cog Thread Lift

The Principles of Facelift with Absorbable Threads; A Comprehensive Guide to Non-Surgical Rejuvenation

Everything you need to know before and after a thread lift; from the mechanism of action to aftercare and results.

1What is an absorbable thread lift?

Absorbable thread lift is a minimally invasive skin rejuvenation and lifting procedure in which very thin, absorbable threads made of biocompatible materials are inserted under the skin. In addition to creating a mechanical effect and immediate tissue tightening, these threads stimulate the production of collagen and elastin, which over time leads to firmness, clarity, and natural skin lifting. The threads are broken down and absorbed by the body after a while, but their effect continues through the collagen tissue that is created in response to the presence of the thread.

This procedure is known as an alternative to facelift surgery, correcting mild to moderate sagging skin without the need for extensive surgical incisions, general anesthesia, and a long recovery period.

Simply put: absorbable threads do two things at once; first, they apply an immediate physical pull to sagging tissues, and second, they stimulate collagen production deep within the skin by activating the body's natural repair process.

2History and evolution of the method

The idea of ​​thread lifting was first introduced in the 1990s with non-absorbable threads. In that first generation, problems such as thread protrusion, lack of lasting effect and undesirable side effects were seen. Over time, new generations of threads were born:

  • First generation: non-absorbable sutures with sharp hooks; with high complications and unstable results.
  • Second generation: Absorbable PDO (polydioxanone) threads with cone pins for tension transfer.
  • Third generation: Multidirectional threads (such as multidirectional and cog threads) with greater lifting power and more uniform force distribution.
  • Fourth generation: Combined and coated threads (such as threads coated with hyaluronic acid or PLLA/PLCL) which, in addition to lifting, have a stronger hydrating and collagen stimulating effect.

Today, absorbable threads have become the first choice of many doctors in non-surgical facelifts due to their high safety, natural decomposition in the body, and lack of need for removal.

3Mechanism of action of absorbable sutures

The therapeutic effect of absorbable sutures is the result of the synergy of several mechanisms:

1) Mechanical effect (instantaneous stretching)

Cog threads have tiny teeth that attach to the subcutaneous tissue and, as the thread is guided, the tissues are moved upwards and backwards. The result of this tightening is visible immediately after the procedure.

2) Stimulation of collagen formation (Neocollagenesis)

The presence of the thread in the tissue creates a controlled and beneficial inflammatory response; fibroblasts are activated and the production of collagen types 1 and 3 increases. This process begins around the third week and peaks within 3 to 6 months.

3) Improve blood circulation and oxygenation

Threads improve local blood flow by creating microvascular changes, resulting in radiant and youthful skin.

4) Localized fat burning (mild lipolysis)

In areas with high fat content, such as the jawline and under the chin, threads can reduce the accumulation of fat cells to some extent and help to make the jaw angle more pronounced.

Key point: About 70% of the final effect of a thread lift is formed through new collagen formation within 2 to 6 months after treatment; therefore, results should not be judged based on the first day alone.

4Types of absorbable sutures

PDO thread

The most widely used absorbable thread with a history of use in heart and gynecological surgeries. It is absorbed between 6 and 8 months and has good collagen stimulation.

PLA/PLLA yarn

Polylactic acid; slower absorption (12 to 18 months) and stronger collagen-building effect, suitable for skin firmness and clarity.

PCL yarn

Polycaprolactone; with a duration of up to 18 to 24 months, it has the longest effect among absorbable threads and is more suitable for thinner skin.

Cog threads

Features single- or double-sided micro-serrations to grip tissue and create a true lift; the ultimate choice for cheeks, jawline, and neck.

Multi and spiral threads

Ribless, spiral or mesh; mostly used to stimulate collagen, refine tissue, and cover fine lines.

Covered yarns

Threads coated with hyaluronic acid or vitamins that, in addition to lifting, also enhance hydration and improve skin quality.

5Who are suitable candidates?

Absorbable thread lift provides the best results in the following conditions:

  • Ages 30 to 55 with mild to moderate sagging skin and soft tissue.
  • Sagging cheeks, deep nasolabial folds, sagging jawline and jugular folds.
  • Desire for rejuvenation without surgery, general anesthesia, and a long absence from society.
  • Skin with minimal elasticity (tissue snapping), neither too much nor too little facial fat.
  • Good general health and no active autoimmune diseases or uncontrolled clotting disorders.
Who are not suitable candidates? People with severe sagging and excess loose skin (facelift surgery candidates), pregnancy and breastfeeding, active skin infection, active autoimmune disease, uncontrolled diabetes, coagulation disorders or taking strong anticoagulants and fractions who expect a result equivalent to surgery.

6Benefits of absorbable thread lift

  • No surgery: No need for large incisions, general anesthesia, or hospitalization.
  • Immediate result + gradual improvement: Instant lift with thread tension and growth of the result over the following months with collagen production.
  • Short recovery period: Most people return to normal activities within 2 to 7 days.
  • Naturalness of the result: Facial movements are preserved and do not create an artificial expression.
  • Relative reversibility: Because the threads are absorbed, the effect gradually diminishes if you are dissatisfied.
  • Dual effect: both lifting and improving the quality, clarity, and softness of the skin.
  • Repeatability: No obstacles to repeat treatment in the future.
  • Lower price than surgery: Especially considering the hidden costs of surgery and time off from work.

7Disadvantages and limitations

  • Limited durability (usually 12 to 24 months) compared to facelift surgery.
  • Temporary swelling, bruising, and dullness may occur in the first few days.
  • Possibility of inconsistency or protrusion if the thread is not placed correctly.
  • Need to repeat treatment to maintain results.
  • Most effective in mild to moderate sagging; results are limited in severe sagging.
  • Requires high skill and precise anatomy from the doctor; the result is highly dependent on the technique.

9Steps for performing a lift with absorbable threads

1) Consulting and design

The doctor determines the thread placement plan, number and type of threads by examining the facial anatomy, skin quality and degree of sagging. Photos are taken before treatment.

2) Preparation

The skin is cleaned with a disinfectant solution. If necessary, the thread entry lines are marked with a pen.

3) Numbness

The area is completely numbed with a topical anesthetic cream and lidocaine injections at the entry points. The entire procedure is usually performed while you are fully awake.

4) Threading

With a fine needle or cannula, the thread is guided into the subcutaneous layer (around the SMAS). The number of threads is usually between 4 and 12 per area depending on the design. The entire procedure takes about 45 to 90 minutes.

5) Finishing work and symmetry control

The doctor checks and corrects the symmetry of the two sides, covers the entry points with a light dressing, and provides aftercare instructions.

Note: A thread lift is an outpatient procedure; you can go home the same day after, but for the first 24 hours, it's best to be alone and not have a heavy schedule.

10Pain and numbness; how painful is it?

Due to effective local anesthesia, there is no significant pain during the procedure; more of a gentle stretching and pressure in the tissue is felt. After the anesthesia wears off (6 to 8 hours), a feeling of stretching, stiffness, and mild pain in the treatment area is normal, which subsides within 2 to 5 days and can be controlled with simple painkillers.

بخوانید
Skin, Hair & Nail Disorders
  • Mild headaches are common after a cheek and brow lift.
  • It is normal to feel stiff when laughing or opening your mouth for a few days.
  • Severe pain, throbbing, or increasing redness is abnormal and should be reported to a doctor immediately.

11Post-absorbable thread lift care

The first 24 hours

  • Sleeping on your back with your head above the level of your heart (two pillows).
  • Avoid touching, massaging, and pressing on the treatment area.
  • Use indirect cold compresses to reduce swelling.

First week

  • Avoid vigorous facial movements; limit chewing hard foods.
  • Avoid heavy exercise, swimming pools, saunas, and solariums.
  • Sleeping only on your back and not on your face.
  • Do not apply makeup to the treatment area until authorized by the doctor.
  • Avoiding extreme facial movements (loud laughter, wide open mouth).

2 to 4 weeks

  • Do gentle exercises and gradually return to your normal routine.
  • Avoid other facial treatments (filming, lasers, invasive massages) without a doctor's approval.
  • Regular use of sunscreen for lasting results.
Note: Dentistry, facial manicures, aggressive massage, and any technique that puts pressure on facial tissue are prohibited for at least 4 weeks after threading.

12Possible complications and ways to prevent them

ComplicationIntensityDurationSolution
InflationCommon and mild2 to 7 daysCold compress, head elevated while sleeping
BruiseCommon5 to 14 daysFades spontaneously; accelerated with arnica
Pain and tensionMild2 to 5 daysSimple painkillers (not ibuprofen in the first 24 hours)
Inconsistency/prominenceMedium2 to 4 weeksOften corrected with massage by a doctor
Infectionscarce—Adherence to disinfection and use of antibiotics if prescribed
Thread protrusionscarce—See a doctor for correction or removal
Permanent nerve damage/asymmetryVery rare—Prevention by choosing a skilled and experienced doctor
Key sentence: The biggest factor in reducing complications is choosing an experienced doctor and a reputable clinic, because the results and safety of a thread lift depend largely on technique and knowledge of anatomy.

13Durability of results

  • The effect of mechanical lifting: is immediately noticeable and decreases slightly during the first 2 to 3 months, partly due to initial tissue liquefaction; then it stabilizes with new collagen formation.
  • PDO threads: absorption 6 to 8 months; overall effect usually 12 to 18 months.
  • PLLA/PLA thread: absorption up to 18 months; overall effect up to 18 to 24 months.
  • PCL thread: absorption up to 24 months; overall effect up to 24 months and more.

Factors affecting longevity include age, skin quality, lifestyle (smoking, sleep, nutrition), degree of facial muscle engagement, and regular use of sunscreen and skin care. Repeat treatments are usually recommended every 12 to 18 months to maintain results.

14Comparing lift with absorbable threads and other methods

MethodInvasionRecoveryDurabilitySuitable for
Lift with absorbable threadLow2 to 7 days12 to 24 monthsMild to moderate sagging + collagen production
Filler (gel)Very little1 to 3 days9 to 18 monthsVolume; limited lift
BotoxVery littleNo4 to 6 monthsDynamic lines; no lift
Laser and ultrasound (HIFU)Non-invasiveNo, up to 2 days12 to 18 monthsSkin tightening; gentle lift
Surgical faceliftTop2 to 4 weeks7 to 10 yearsSevere sagging

Conclusion: If you have mild to moderate sagging and want to achieve both a lift and improved skin quality without surgery, an absorbable thread lift is one of the best options. For severe sagging, surgery is still the final choice.

15Combining thread lift with other treatments

  • Filler: To restore volume to the cheeks and chin along with a lift; usually 2 to 4 weeks after threading.
  • Botox: To remove dynamic lines (forehead, crow's feet) and create a synergistic chemical lift; 1 to 2 weeks later.
  • Mesotherapy and vitamin mesococktail: to enhance skin quality; after 2 weeks.
  • HIFU or radiofrequency: for more skin tightening; usually 1 to 2 months after thread lift.
  • Laser and microneedling: To refine the skin surface and pores; with appropriate time intervals.
Golden Program: The combination of absorbable thread + volumetric filler + Botox, known as the evolutionary liquid lift or the combination of thread lift with HIFU, offers results close to surgery with much less invasiveness.

16Cost and factors affecting it

The cost of a facelift with absorbable threads varies depending on several factors:

  • Number and type of threads: Ribbed threads and PCL or coated threads are more expensive than simple multi-thread PDO threads.
  • Treatment area: Cheek and jaw lifts cost more than brow lifts or fine lines.
  • Yarn brand: Reputable Korean and European brands with higher quality have different prices.
  • The doctor's experience and the clinic's geographic location are the main determining factors in cost.
  • Combination with other services: If combined with fillers or Botox, the total cost will be higher.

During your consultation, be sure to ask your doctor for a written estimate of the number of threads and total cost to avoid hidden costs.

17Choosing the right doctor is your most important decision.

  • A dermatologist or plastic surgeon with a proven track record in thread lifts.
  • View before and after photos of real portfolios (not edited images).
  • Using original and licensed threads with sterile packaging and holograms.
  • Procedure in a sterile and standardized environment (reputable clinic, not informal environments).
  • Transparent advice about realistic expectations and an honest explanation of possible complications.
  • Regular follow-up care after the procedure and acceptance of responsibility for correction if needed.

18Frequently Asked Questions

Is thread lift painful?

With local anesthesia, there is no significant pain. Afterwards, mild stretching and soreness are normal for a few days, which can be controlled with painkillers.

How long does it take to see the full result?

The tightening effect is immediate, but the final and lasting result is completed within 2 to 6 months with the collagen formation process.

Do the stitches need to be removed later?

No; absorbable threads gradually break down and are absorbed by the body and do not need to be removed.

Does the face look artificial?

With proper design and professional threading, the result is completely natural and facial movements are preserved.

When can I wear makeup?

Light makeup is usually allowed after 7 days, with the doctor's approval.

Can I get fillers or Botox later?

Yes; usually, other treatments can be performed 1 to 4 weeks after threading, and even combining them gives better results.

What if I am not satisfied with the result?

As the threads are absorbed, the effect gradually diminishes. Some cases of misalignment can also be corrected by the doctor in the first few weeks.

Is it suitable for men too?

Yes; it is one of the most popular methods among men, especially for lifting the jawline and reducing sagging under the chin.

19Conclusion

Absorbable thread facelift is a minimally invasive, effective, and safe solution for addressing early and intermediate signs of skin aging. Combining immediate tightening and natural collagen stimulation, this procedure delivers both a noticeable lift and improved skin quality without the need for surgery, general anesthesia, or a long recovery period.

The key to the success of this treatment is three things: choosing the right candidate, choosing a skilled doctor, and following the aftercare instructions carefully. By following these three principles, you can expect natural, beautiful, and long-lasting results (12 to 24 months) and experience facial rejuvenation without the stress of surgery.

Final advice: Before making a decision, be sure to have an in-person consultation with an experienced dermatologist or plastic surgeon so that a treatment plan can be designed exactly to suit your anatomy, age, and expectations.
