Different Types of Thread Lifts and Choosing the Right One


What are thread lifts?

The thread lift is a skin tightening technique used in surgery for closing wounds for many decades but has just begun to gain recognition in the cosmetic industry for lifting skin loose skin resulting from aging or weight fluctuation. It uses threads (sutures) made from materials used in surgery to close wounds. In this procedure using fine surgical needles, threads are placed under the skin to tighten and lift loose or sagging areas in various parts of the face and body to help rejuvenate the face. While sutures provide physical support to the loose skin by pulling up the loose skin, they also stimulate the production of collagen that has slowed down due to aging. 


An absorbable thread will break down over time be absorbed into the body. Different absorbable threads will last for around six months to up to 24 months before they are dissolved and absorbed by the body. 

– Polydioxanone (PDO) thread dissolves around 6 months after the treatment.

– Poly L Lactic Acid (PLLA) thread lasts around 12 months. 

– Polycaprolactone (PCL) threads are absorbed 24 months after treatment.



To get effective results, the texture of threads, both absorbable and non-absorbable, is significant. Some textures might work better than others, depending on the treatment area, and sometimes even a combination of threads can be used.


Non-barbed threads: They are smooth and are used in regions with thin tissue such as around the eyes where you don’t want the skin to scrunch up on the surface. These threads are of two types: monofilament plain and monofilament spiral. Both types are 


Uni-directional barbed threads: The threads can be barbed in one direction only,  


Bi-directional threads: These are barbed in two directions and favored by doctors due to the thread being locked into the tissue in both directions, anchoring the thread and giving stability. 


These barbs anchor the thread into the soft tissue under the skin so it doesn’t move, and as they cut in tiny abrasions in the tissues, they trigger the production of collagen in skin tissues to repair itself. Collagen plays an important role in increasing cellular turnover and facial rejuvenation.

Mesh-like net of Threads

Uni-directional and non-barbed threads can be added to create a structure or a mesh-like net These two threads can be moved to make adjustments and corrections after the procedure, but eventually your injector must anchor them in the tissue.


Using the above basic textures, more and more textures are emerging with growing research in the field. To create a different structure and effect, these threads can be braided before being inserted into the skin. All these unique techniques are usually tailored by the clinic you receive treatment at.


The threads can either be long or short in length. Small stitches like nose lift require smaller threads. Barbed threads tend to be longer and can be used across the face, neck, chest,, and even parts of the body.

Different Types of Threads Used

Three main types of threads are populalrly used for thread lifts; polydioxanone (PDO), polylactic acid (PLA),, and polycaprolactone (PCA). 


PDO threads

PDO threads has been around the longest and were traditionally used for surgical stitches.  These thread are made of a synthetic biodegradable polymer and are absorbed into the body over 6 months. They stimulate fibroblasts for increased production of collagen in a targeted area.  They have been proven to be extremely safe.


Currently there are three types of PDO threads mainly used; mono, cog,, and screw threads.


Mono threads – smooth without barbs, mainly tighten the skin and provide a small amount of lift. They and are usually used in combination with other thread types or they are anchored to a point on the face or the scalp. 

Cog threads – have barbs that hook onto the skin to provide support and lift the sagging tissue. Mainly uni-directional barbed thread while Cog 360 has a similar structure to bi-directional barbed thread.  

Screw threads – one or two intertwined  barbed threads around the needle to provide good volume restoration for sunken areas of the skin. They helps to restore volume and improves the skin texture and elasticity by stimulating production of collagen around the threads and their barbs resulting in a natural aesthetics outcome.


PLA threads

PLA threads were developed from a biocompatible polymer derived from lactic acid that has been previously used in many applications such as orthopedic pins and sutures. PLA threads increase the volume of saggy areas and therefore, help to restore shape to the facial area as well as providing a lift by using cones to hook to the tissue. PLA threads are resorbable and In comparison to PDO threads regenerate collagen over a longer time. 

PCA threads 

PCA threads are the latest bio-absorbable threads that are monofilament suspension threads of synthetic origin (caprolactone). The process of thread breakdown produces molecules of small molecular weight which triggers the production of collagen and Hyaluronic acid by the skin. They induce collagen production for a longer time period than both PDO and PLA threads. As they trigger the fibrotic reaction, even after reabsorbtion they leave behind a collagen structure that provides support for the skin.


This tightens the skin and the lifting and stretching action will continue and prevents it from sagging.  They give a long-lasting result with more moisturized, revitalized, and firm skin.

What to expect after thread lift?

Results – Effects should be visible immediately after the threads are put into place, but you can expect more in the days and weeks right after the procedure is done, as swelling and bruising starts to subside. Depending upon the type of thread lift you opted for typically last from 1 to 3 years .

Recovery Time – Generally, after a successful thread lift there is quite minimal recovery time but there may be some visible swelling or bruising that will subside in days to come. You can even go back to work right away if you’d like. After a thread lift you might be advised to skip your regular moisturizer for the first few weeks. For the first week or so after the procedure you should avoid saunas and high intensity workouts.


Injector will recommend you to avoid putting pressure or rolling over onto the newly placed sutures during your sleep, so it is best to sleep with your head propped up for three weeks.


Benefits of Different Types Thread Lifts

Individual preference, location of the procedure, and desired length of effect will dictate the threads used for treatment. Because the threads stimulate collagen production, choosing a thread with a longer life can be beneficial. It is important to note that, short-term threads serve slightly different functions than long-term threads. 


– PDO thread lifting affective  for 6 months is used for lifting loose skin or contouring facial structure such as nose.

– PLLA that lasts for 12 months gives the face a bit more volume to sunken facial features for example, a person with hollow cheeks is a suitable candidate for PLLA . 

Depending upon your goals you can discuss with your clinician and chose the right thread lift procedure for you.
