Rainbow thread 6D cog PDO threads with needles

6d Cog/6d serrated sutures have 360 degree spirals that run every 60 degrees around the entire circumference.

This is considered the optimal degree to achieve the best anchorage in the superficial muscular aponeurotic layer of the face. 6d Cog/6d serrated threads can restore expression lines, nasolabial folds and sagging skin. They also accelerate blood circulation and promote the production of collagen, which gives the skin a radiant appearance.

6D Cog

The 6D cog was designed with 6-dimensional barbs to maximize the lifting effect. It has been notched finer with 60° degree protrusion. So there are barbs every 60° to fix the tissue in all directions, which provides powerful and long-lasting lifting.

Rainbow 6D cog

Robust 6D filament with spirally arranged multidirectional notches. The notches are placed on six sides of the thread to form a 6D configuration in diameter projection. It has a higher number of serrations than other COG thread types, so the thread grips the fabric as tightly as possible. This results in a uniform and pronounced effect during engagement and also reduces the risk of thread breakage at high tension.

PDO Rainbow Threads Collection

Rainbow Thread is a new concept in premium lifting treatment with non-surgical skin tightening threads that effectively treat sagging skin and create a natural, fresher and younger looking face.

Rainbow Threads come in PDO (Polydioxanone), PLLA (Ply L-Lactic Acid) and PCLA (Poly L-Lactide-co-ε-Caprolactone), which are biodegradable and absorbable threads that have been used for surgical sutures for 50 years. The medical suture material is designed to be inserted into the SMAS layers to tighten and lift the skin, which is suitable for patients with sagging or drooping skin.

As we age, skin tissue becomes thinner due to the breakdown of collagen and elastin fibers, resulting in sagging skin, deep wrinkles and folds. Rainbow threads stimulate fibroblasts and collagen proliferation, causing a natural, dramatic skin tightening and lifting effect as the thread breaks down, improving blood circulation, helping to improve skin tone and repair, and increasing skin elasticity. The non-surgical skin lift is designed to provide a long-lasting effect with immediate results.

Rainbow Threads are certified as Class III devices under the European Medical Device Directive and carry the CE mark, which guarantees the quality and safety of the product.

Active ingredients

PDO: Polydioxanone


PDO is used to tighten and rejuvenate the skin. PDO thread dissolves naturally and is absorbed into the dermis layer after 3 to 6 months. It helps to produce the reproduction of collagen to maintain the lifting effect and improve skin tone.


‥ Generates collagen by injecting PDO. (PDO is approved as a suture thread)

‥ Wound healing process in action

‥ Regenerates skin cells, increases collagen formation and improves blood circulation, which helps skin repair and increase elasticity.


PDO begins to gradually break down about 2 weeks after the procedure and is completely dissolved after 8 months to 1 year.

PLLA (Poly-L-Lactic Acid)


Poly-L-lactic acid is one of the FDA approved body ingredients (PLLA is produced from corn and sugar cane)

- The effect of PLLA on neocollagenesis has been proven by worldwide clinical trials. PLLA has been approved by the FDA and is now used as a major ingredient in fillers (1999)

PLLA thread has better tension and elasticity in vivo than PDO thread. PLLA can be manufactured as rod and screw type to maximize the benefits

- PLLA has no pigmentation problems like plastic dyes and contains only components that are harmless to the human body.


After 1 month, collagen starts to form around PLLA, and then PLLA will gradually degrade and

Induce collagen formation.

PLLA is completely degraded and replaced by collagen within 18 to 24 months.

The excess is excreted in the urine.

PDO thread mechanism

PDO threads are used to tighten and rejuvenate the skin. PDO thread dissolves naturally and absorbs into the dermis layer after 3 to 6 months. It helps to fix the skin and promote the activities of collagen and cellular tissue.

Insert PDO threads into the dermis in an even direction to lift the muscle and add elasticity to the skin and activate fibroblasts. Even if the PDO thread dissolves, it continuously helps to reproduce collagen to maintain the lifting effect; it also improves skin tone.

PDO threads can be used on any areas with different types of threads for individual treatments. The treatment time is comparatively short and there is no downtime.

PDO Mechanism

The concept of skin rejuvenation is that the barbed PDO thread, an absorbable thread, has a special design to attach our tissue under the sagging skin so that the lifting result is visible immediately after the procedure. Later, the threads gradually stimulate collagen production until they are completely absorbed by the body within 6 months. After this time, our own collagen will lift the skin, and the result will last for 1-2 years.

Polydioxanone sutures, commonly referred to as PDO sutures, have been known in the medical field as absorbable surgical sutures since the 1980s. Sutures. Recently, however, they have been actively used in aesthetic medicine and have become one of the leaders in modern rejuvenation techniques.

Polydioxanon sutures are a response to the trends and developments that call for stimulating the skin's natural protective and regenerative mechanisms instead of using masks. Regenerative mechanisms of the skin, instead of concealing aesthetic flaws.

PDO threads have a revitalizing, firming effect and stop the process of skin aging. From active Polydioxanon threads inserted under the skin stimulate the body's own production of collagen and elastin and are a long-term support for sagging, wilted skin.

Importantly, PDO threads do not increase facial volume and produce very good results in difficult areas where treatment is inadequate. Treatments with botulinum toxin and hyaluronic acid are insufficient.

PDO threads - active lifting and effective revitalization .

Polydioxanone sutures are used as self-absorbing surgical sutures in the most critical areas: Skin and subcutaneous sutures in plastic surgery, ophthalmology, urology and gynecology. Recently, they have also been used in aesthetic medicine.

Just a few years ago, scientists from South Korea discovered that combining PDO sutures with acupuncture strengthens the body's muscles and tendons

Previous clinical observations have shown that in response to the presence of certain foreign bodies, the body stimulates the production of collagen (the protein responsible for skin tone and elasticity) and elastin (the protein responsible for skin firmness and elasticity).

This process begins about 14 days after the PDO thread is inserted into the skin and lasts up to 9 months, i.e. until the suture is completely tung. After this time, the polydioxanone threads are completely hydrolyzed, and the decomposition products, i.e., carbon dioxide and water, are completely inert to the body.

Along the threads, new collagen is formed in the skin, which is the perfect basis for preventing the skin from sagging and aging. The aesthetic effect is long lasting, up to about 2 years.

Rainbow Thread

The main types of PDO threads

There are several types of polydioxanone threads. The choice depends on the patient's age, skin type and condition, and aesthetic requirements. Effect we want to achieve. The most commonly used are:

1.Monofilaments - simple. Made of only one fiber, the monofilament.

2.Twisted. These are monofilaments that are wound around a needle much like a spring.

3.Serrated yarns - with hooks. These threads contain micro-reliefs on the entire surface, which provide additional support mechanical lifting of the skin.

PDO Needle Types

Mono type

Mono-types are mainly intended for skin tightening, regeneration and rejuvenation.

Mono-types help to remove wrinkles and improve facial contours.

They also act as a support for Cog types and help the lifting effect last longer.

PDO Mono


PDO mono is a biodegradable, absorbable thread recommended for facial reinforcement.

Activates collagen synthesis, blood circulation and lymphatic drainage. Restores sagging skin, reduces dullness.

screw PDO Mono


PDO spiral threads are recommended for volume restoration.

Due to its spiral shape wrapped around the needle, the thread has a better regenerative effect than PDO monofilaments. The filament is flexible and elastic, which is especially important when correcting areas of high mimicry activity.



PDO Twin consists of two yarns that are interwoven and knotted together. The presence of knots during insertion keeps the fabric under tension so that it can not return to its original position. This form allows the greatest lifting effect. The threads are not visible through the skin and do not reveal themselves visually or haptically

Rainbow i PDO Mono

Rainbow i

Rainbow i is a monofilament with a U-shaped cannula specially designed for the treatment of the eye area to reduce dark circles and wrinkles.

Atraumatic and safe correction, minimal risk of bruising.


The barbs firmly fix the skin tissue to lift sagging skin and redefine facial contours.

3D cog

3D cog

The 3D thread has 360 degree spiral notches around the entire circumference of the thread. 120 degrees, which allows tightening the heavy tissues of the face and neck and solves a number of problems: even pronounced ptosis is eliminated, double chin and ruffles are removed, skin tone is improved. Effective for fixing large areas of skin

The technique is recommended for the correction of the lower and middle face in patients aged 30-45 years.

6D cog

6D cog

Robust 6D filament with spirally arranged multidirectional notches. The notches are placed on six sides of the thread to form a 6D configuration in diameter projection. It has a higher number of serrations than other COG thread types, so the thread grips the fabric as tightly as possible. This results in a uniform and pronounced effect during engagement and also reduces the risk of thread breakage at high tension.

Heart Lifting

Heart Lifting

Heart Lifting is an innovative notched thread produced by the casting process

Unlike serrated threads, the notches are not damaged in the casting process, as the thread is produced by pressing in a mold.

This technology extends the period of biodegradation, resulting in a longer lasting effect.

The unique heart-shaped design of the cuts provides maximum lifting effect.



Ultra and Ultra + are thinner filaments (USP 5-0) than other notched filaments (USP 1-0 / 2-0), but can still withstand high stresses. Suitable for tissue modeling even in the most delicate and difficult to reach areas of the face.

Dual arm

Dual arm

DualArm uses notched threads with two needles at the end of each thread and is commonly used on the forehead, eyebrows, cheeks, etc.

The needles are incredibly flexible and sharp, allowing the thread to be guided into the skin tissue at the desired contour with a single insertion



PLLA: Poly-L-lactic acid.

- Rejuvenating effect - triggers neocollagenesis

- Longer lasting results compared to PDO filaments

- Degrades naturally in the body within approximately 18 months

- Results last up to 24 months



These are copolymerized absorbable PCL and PLLA components with a history of more than 120 years and technology unsurpassed in the medical field.

* Longer biodegradation time than PDO. Same raw materials as APTOS and HappyLift

* Longer corrective effect. Longer biodegradation period, 12-18 months.

PCLA Heart

PCLA Heart

Hi Rhino

Hi Rhino

Hi Rhino is a lifting thread for non-surgical nose correction.

The thread is inserted into the nasal septum, bridge, tip and wings.

This bi-directional, notched thread provides a locking and anchoring effect and lifts the tip of the nose with minimal tissue trauma.
