Definisse Revitalise Threads is a dissolvable thread from Relife, part of the Menarini group, in the Smooth 5 cm version. It is made from P(LA-CL), a copolymer of poly-L-lactide and caprolactone, designed to restore skin quality and stimulate collagen production around the thread track. The Smooth version has no barbs for gripping tissue, so it focuses on tissue response and skin quality rather than mechanical lifting like a barbed (cog) thread, and it is not an injectable fresh collagen. Accurate communication should therefore use the term "collagen-stimulating smooth thread" or "PCLA CL skin restoration programme."

What Is PCLA CL
P(LA-CL) is a biodegradable copolymer composed of poly-L-lactic acid and caprolactone. Combining these components aims to balance strength, flexibility, and how long the material stays stable in tissue. As the material gradually breaks down through hydrolysis, remodeling occurs around the thread track. The manufacturer states that Revitalise threads help stimulate collagen types I and III, and communicates that the response can continue for up to about 18 months. However, this figure is product-specific data and should not be interpreted as a guaranteed result for everyone. Actual results depend on the position, number of threads, technique, skin age, behaviour, and individual response.
Why It Should Not Be Called Fresh Collagen
In the Thai market, the term "fresh collagen" is often used for injectable atelocollagen, such as purified animal-derived collagen gel. Definisse Revitalise, on the other hand, is a synthetic thread that stimulates the body's own response and builds extracellular matrix components around the thread track, so it is a different product category — even though some of the end goals relate to skin quality and collagen in a similar way.
| Aspect | Definisse Revitalise Smooth | Injectable Atelocollagen |
|---|---|---|
| What is placed in the skin | Dissolvable P(LA-CL) thread | Purified collagen gel |
| Main mechanism | Small support scaffold and tissue remodeling around the thread track | Direct collagen supplementation and tissue response |
| Planning | Number of threads, direction, layer, and area | Volume, injection points, and tissue layer |
| Reversal | No dissolving enzyme like HA | Also no hyaluronidase like HA |
| Best suited when | The physician wants skin quality along a direction and area | The problem responds to collagen gel |
Skin Restoration Mechanism
After the thread is placed in the appropriate layer, tissue undergoes a controlled response to the biomaterial, with fibroblast activity and reorganisation of the extracellular matrix around the thread track.
- Early stage — you may feel tightness or firmness from thread placement and temporary swelling.
- Later stage — tissue remodeling occurs around the thread track and skin quality gradually changes.
- The thread gradually degrades according to the material's properties, but the tissue response may continue after the material starts to break down.
- The Smooth version has no barbs for gripping tissue, so it should not be advertised as lifting the face to the same degree as a lifting (cog) thread.
Skin Problems a Physician May Consider
บริเวณที่แพทย์อาจพิจารณา Definisse Revitalise Smooth
- Skin that is starting to thin or has reduced elasticity
- Fine lines and slightly crepey skin in some areas
- Skin quality of the cheeks, jawline, neck, or décolletage according to the indication and assessment
- Those who want a gradual skin restoration plan without wanting significant added volume
- Those suited to combination treatment with a tightening device or other injectables, in a sequence planned by the physician
This programme is not the only answer for every degree of laxity. If there is fat displacement, weakened supporting ligaments, bone resorption, or clearly excess skin, the physician may consider cog threads, energy devices, filler, or surgery depending on the root cause.
Who Should Postpone or Avoid
- Pregnant or breastfeeding
- Infection, wounds, inflamed acne, or active herpes in the treatment area
- Bleeding disorders, immune abnormalities, or use of blood-thinning medication that has not yet been assessed
- History of keloids, granulomas from implanted materials, or allergy to any component
- Permanent material or existing threads in the same area with an unclear history
- Expecting a strong lifting effect, when the Smooth version is focused on skin quality
Treatment Steps to Expect
- Take a history of medications, supplements, underlying conditions, allergies, and previous procedures
- Analyse skin thickness, laxity, movement, and anatomical layers
- Check the Smooth 5 cm box, number of threads, registration number, expiry date, and packaging
- Design the thread direction and number of threads for the individual
- Clean and maintain asepsis, with anaesthesia as appropriate
- The physician places the threads in the designated layer and checks symmetry
- Provide aftercare advice and schedule a follow-up
When Results Begin and How Long They Last
In the early period you may notice some tightness or smoothness, but this must be distinguished from swelling. Skin quality results are usually assessed over several weeks to several months. The manufacturer communicates that biostimulation can continue for up to about 18 months, but this is not a guarantee that everyone will see or maintain the same result. Photos should be taken in the same light and angle and assessed at follow-up.
The number of threads and sessions should not be fixed into a rigid formula, because it depends on the area, skin quality, severity, and goal. The physician determines this after a real examination.
Sensation, Downtime, and Aftercare
แพทย์ตรวจสอบไหม Definisse ก่อนทำหัตถการ
During the procedure you may feel tightness, tugging, or pain along the thread line even with anaesthesia. Afterward you may have swelling, redness, bruising, tenderness, a sensation of the thread line, uneven skin, or temporary dimpling.
- Avoid pressing, massaging, or doing treatments on the area yourself
- Avoid strenuous exercise, intense heat, saunas, alcohol, and wide mouth-opening for the period the physician specifies
- Sleep in a position that reduces pressure on the treated area and keep the wound clean
- Use only medication prescribed by the physician; do not buy your own antibiotics or anti-swelling medication
- Contact the clinic if pain worsens, there is hot red swelling, pus, fever, skin colour change, or a thread tip becomes visible
Risks and Limitations
Complications of thread procedures may include swelling, bruising, pain, dimpling, asymmetry, a palpable or visible thread, infection, thread migration, thread extrusion, inflammatory nodules, and nerve irritation. Risk depends on the material type, thread shape, technique, position, and the practitioner's experience. Using the phrase "100 percent safe" or "no downtime" is therefore not appropriate.
Comparison with Other Programmes
| Programme | Material or mechanism | Main strength | Things to know |
|---|---|---|---|
| Definisse Revitalise Smooth | P(LA-CL) smooth thread | Restores skin quality along the thread track, stimulates remodeling | Not a cog thread, not injectable collagen |
| PDO Smooth thread | Polydioxanone | Widely used, relatively short material duration | Results and timing depend on the version, number of threads, and technique |
| PLLA thread | Poly-L-lactic acid | Emphasises collagen response and stays stable longer than some PDO versions | Stiffness and response vary by product |
| PCL thread | Polycaprolactone | More flexible and degrades more slowly in some products | Evidence and indications vary by brand |
| Cog thread | Various materials, barbed | Grips and repositions tissue for mechanical lifting | Downtime and contour risk can be higher than smooth threads in some cases |
| Atelocollagen | Purified collagen gel | Directly supplements collagen at the chosen position | A different category from threads, no HA-type dissolving enzyme |
| PN Polynucleotide | Polynucleotide | Focuses on the skin environment, hydration, and repair | Does not provide a thread-type scaffold |
| HA Filler | Hyaluronic acid gel | Adds volume, adjusts contour, shows shape quickly | Vascular risk exists, but HA can be corrected with hyaluronidase |
| Injectable PLLA | Collagen-stimulating powder | Gradually reshapes structure over a wide area | Requires planning of volume, distribution, and monitoring for nodules |
| CaHA | Calcium hydroxylapatite | Provides scaffold and biostimulation according to the formula | Position and dilution matter, not suitable for every area |
| RF / HIFU | Thermal energy | Tightens and remodels at the target layer | No material is placed, but results depend on the device, energy, and anatomy |
How to Choose Between Definisse Revitalise and Other Programmes
- If the goal is skin quality and a small scaffold thread is wanted, the physician may consider Revitalise Smooth
- If clear tissue lifting is wanted, cog threads or another lifting approach should be assessed
- If filling a fold or adjusting contour is the goal, HA filler may be more suitable
- If an injectable skin programme is wanted, PN, atelocollagen, HA bioremodeling, or a biostimulator may be considered
- If there is laxity from multiple layers, a combination plan may be needed rather than doing everything at once
