The threads used in the Thread Lift are made of soluble PDO which is a material that has been used in medicine for many years, mainly in surgery. However, research has shown that PDO relaxes muscles and tendons, and also stimulates the neocollagenesis process, which encourages the production of new collagen in the skin. PDO also stimulates the synthesis of elastin and hyaluronic acid in the skin, both of which are vital for keeping the skin looking plump and youthful.
The PDO thread is inserted into the skin through a very fine needle. Depending on the area to be treated, the thread is introduced into either the skin itself, the subcutaneous fat, or the muscle. A lifted appearance can be seen immediately following the treatment, however, the results will improve in the following days and weeks as the PDO stimulates neocollagenesis, which in turn produces collagen. The overall texture of the skin is improved; it becomes thicker, tighter and firmer and fine lines and wrinkles are smoothed away.
Different thicknesses and types of thread are used for different areas of the face. Short, non-barbed threads can be used to treat fine lines on the face, as well as tightening and lifting areas such as the jawline and neck. Thicker “cogs” or barbed threads can give a significant improvement to the mid and lower face. Sometimes we will use a combination of both non-barbed and barbed threads to give the best results.
The threads are naturally absorbed by the body in six to eight months, however, the effect of the treatment can last for up to two years.
