What are Rainbow Threads?

Rainbow Threads are a line of PDO (Polydioxanone) threads designed for non-surgical anti-aging treatments to lift and shape facial contours. They stimulate collagen formation, restore skin cells, enhance blood circulation, and improve the complexion.

This line of threads was created by Oreon Life Science, a South Korean medical company specializing in medical aesthetics.

These threads are made from PDO, a biodegradable and absorbable medical material commonly used in surgical sutures. Rainbow Threads manufacturer offers a wide range of threads designed explicitly for non-surgical anti-aging treatments to lift and shape facial contours.

Threads are inserted into the SMAS layers, lifting and tightening the skin. As they degrade, they stimulate collagen formation, which restores skin cells, enhances blood circulation, and improves the complexion. These PDO threads are developed using innovative technologies, ensuring they are of the highest quality.

These threads come in Polydioxanone (PDO), Poly L-lactic Acid (PLA), and Poly L-lactide-co-ε-caprolactone (PCLA).

There are different Rainbow Threads available for different cosmetic needs:

Mono Threads are designed with a sharp needle, making them ideal for remodeling facial contours with immediate and long-lasting results. These are single, smooth threads used to tighten and firm specific areas of the skin.

Screw Threads are created with two twisted mono sutures wrapped around the needle, giving them unique properties that provide a more powerful lifting result. These threads have a corkscrew shape and are used to lift and tighten the skin in a twisting motion.

COG Threads are made with barbs that make the thread stronger and more stable, resulting in longer-lasting and more visible lifting effects. PDO COG threads are similar to traditional barbed threads. However, they have a unique “cog” design that allows for more significant lift and support of the skin. The cogs are tiny barbs or hooks spaced along the thread, allowing it to grip the skin and hold it in place more effectively.

Special Line Threads series have unique characteristics that provide the best results without side effects and guarantee patient comfort. This line is represented by Rainbow Gold embossing Threads – smooth, lifting thread made of polydioxanone with a 24-carat gold coating. The gold material helps stimulate the body’s collagen production, improving skin texture and firmness.

Rainbow threads’ costs vary depending on the line and your desired product. The Mono line products are the cheapest, and the threads from the PCLA Cog line are the most expensive. To learn about prices for specific products, please visit the product pages on our website.

When selecting the type of Rainbow Thread, it’s essential to consider the specific cosmetic goals of each patient and select the most appropriate thread type accordingly.

How Do They Work?

Thread procedures are non-surgical cosmetic treatments that involve tiny, barbed threads to lift and tighten the skin on the face and neck. The threads are carefully inserted under the skin using a needle, then gently pulled to lift and tighten the skin.

The threads are made of a biocompatible material that the body absorbs over time, stimulating elastin production. This property improves the skin’s texture and firmness, leading to a more youthful appearance.

The absorbable suture material is composed of E-Caprolac and L-lactide, which allows it to be fully absorbed by the body. Polylactic acid, present in the material, promotes collagen production and rejuvenates cells at a cellular level.

Although the external impact of polylactic acid is not immediate, it becomes visible after 2-4 months and peaks at around six months. During this period, new endogenous collagen fibers form in response to the thread’s presence, which is neocollagenesis.

This natural process of tissue formation continues even after the complete resorption of the thread’s microparticles. The effects of thread lifting can last for two years.

Besides tightening tissue, the threads make the skin firmer, significantly improving its quality.

Rainbow threads are a minimally invasive alternative to surgical facelifts. They treat various skin problems, including fine lines, wrinkles, and sagging skin.

The treatment is ‌well-tolerated; most patients can return to normal activities immediately after the procedure. However, as with any cosmetic treatment, there are risks and potential side effects.

What Are They Used For?

Because of the breakdown of elastin fibers, skin becomes thinner as we age. It leads to sagging skin and the appearance of creases, folds, and wrinkles.

Rainbow threads stimulate fibroblasts, and give skin tightening and lifting through the thread’s degradation, enhancing blood circulation and improving skin tone and elasticity.

Rainbow threads effectively solve problems with deep wrinkles, forehead wrinkles, lip wrinkles, crow’s feet, etc. By the strong lifting result, they help skin regeneration of line adhesion.

They stimulate SMAS layers to tighten the slacking skin and simultaneously promote skin regeneration to activate the generation of skin proteins (collagen, elastin).

PDO thread treatment stops the wrinkle adhesion around the neck, which mainly develops through aging; they rejuvenate and regenerate skin.

Different Rainbow Threads are available on the market, each with unique properties to provide different lifting effects. The type of thread used depends on the individual patient’s needs and the areas of the face or neck being treated. A qualified and experienced provider will recommend the best type of thread for each patient’s unique concerns and goals.

Doctors who work with these products leave many positive Rainbow threads reviews, reporting excellent results from their patients.

How To Use Rainbow Threads

The threads are inserted under the skin using a fine needle during a Rainbow thread-lifting procedure. Once in place, the threads are gently pulled to lift and tighten the skin, creating a more youthful and rejuvenated appearance.

They dissolve over time, stimulating the body’s natural elastin production, which helps improve skin texture and firmness.

As a doctor, it’s essential to know the different threads used in thread lift procedures and the potential benefits, risks, contraindications, and side effects associated with these procedures.

You must have expert knowledge of the anatomy of the face and the underlying structures that the procedure may affect. You should also be familiar with the proper technique for inserting the threads and any potential complications that may arise.

You need to assess each patient individually and evaluate their medical history, skin type, and cosmetic goals before recommending any specific procedure. In addition, as with any cosmetic procedure, it’s essential to have a detailed discussion with the patient about the expected outcomes, potential risks, and any alternative treatment options that may be available.

In addition, it’s vital to have the training and experience to perform the procedure safely and effectively. Therefore, you must consider undergoing specialized training in thread lift procedures and staying up-to-date on the latest techniques and advancements in the field.


On average, the rehabilitation phase lasts 7–14 days, depending on the individual characteristics of the body and the stress level.

The thread integrates for up to 40 days. Your patient should avoid strong skin movements and pronounced facial expressions during this time and wear a compression mask at night for two weeks.

Restrictions after the treatment:

  • • Within 1.5 weeks, saunas, baths, and solariums are prohibited.
  • • Heat treatments on the areas where the threads were implanted are banned for one month.
  • • Massages, physiotherapy treatments, or anything that disturbs the integrity of the skin (mesotherapy, injections, etc.) should be avoided for two months.

How Long Do Results Last?

Depending on the type, Rainbow Threads can last from 12 to 18 months (PDO, PLLA) to over a year (PCLA); they have ideal solidity and are also known to be very potent at stimulating collagen production.

Are They Safe?

Certification guarantees the quality and safety of threads as class III under the European Medical Device Directive with the CE mark and has been proven in clinical studies.

However, as with any cosmetic procedure, there are risks and potential side effects, so it’s important to discuss the process with your patients before they decide if it’s right for them.
