COGS and PDO Threads
COGS and PDO threads are two types of specialized threads used in non-surgical facelifts to lift and tighten sagging skin, providing a more youthful appearance.
​
-
COGS threads are barbed threads with tiny hooks that grip the skin, allowing for a more dramatic lift as they are pulled upward. They are used to contour and lift areas like the jawline, cheeks, and neck.
-
PDO (Polydioxanone) threads are absorbable sutures that stimulate collagen production as they dissolve over time. They come in different forms, including smooth threads for tightening and thicker, barbed threads for lifting.
Both techniques provide immediate results, which improve over several months as the skin continues to produce collagen. These threads are minimally invasive and provide a temporary yet effective alternative to surgical facelifts.
​
COGS are generally used on the lower face to lift jowls, tighten the neck and create a snatched jawline. They can also be used to raise eyebrows.
​
PDO threads boost collagen to create a lifting and tightening effect. These are usually placed in the neck, face and eyes.
Frequently Asked Questions
What is the downtime?
PDO thread lifts and COGS typically have minimal downtime. You may experience some swelling, bruising, or soreness at the insertion points, which usually subsides within a few days to a week. Most clients can resume normal activities after a few days, though strenuous exercise should be avoided for at least a week.
​
What should I avoid after having my treatment?
After your PDO thread or COGS treatment, it’s important to:
-
Avoid touching or massaging the treated area for at least 48 hours.
-
Sleep on your back with your head elevated to prevent pressure on the threads.
-
Avoid heavy exercise or strenuous activities for 7–10 days.
-
Steer clear of facials, saunas, or any heat-based treatments for at least two weeks.
-
Avoid alcohol and anti-inflammatory medications like ibuprofen, as they can increase the risk of bruising.
Who can't have this treatment?
PDO thread lifts and COGS may not be suitable for:
-
Pregnant or breastfeeding individuals.
-
People with active infections or skin conditions at the treatment site.
-
Those with certain autoimmune diseases or blood clotting disorders.
-
Individuals who have a history of keloid scarring or poor wound healing.
Is it possible to have an allergic reaction?
Allergic reactions to PDO threads and COGS are very rare, as the threads are made from polydioxanone, a biocompatible material that is absorbed by the body over time. However, if you have a history of allergic reactions to surgical materials or have very sensitive skin, you should discuss this with your practitioner before treatment.
