What are the differences between PDO, Spring Threads and Silhouette Soft threads?
PDO threads are made of a substance called Polydioxanone, which has been used for many years for temporary sutures in surgery.
PDO threads come in barbed and non-barbed varieties. They are inserted into the deeper layers of the skin and work by tightening and mechanically lifting the skin and, as time goes on, the production of collagen and elastin within the dermis is increased, due to the induced trauma to the skin, thus encouraging a healing response. The threads are temporary and will dissolve in around 6 to 8 months, leaving behind significantly tighter and lifted skin.

Silhouette Soft® from Silhouette Beauty is a patented Poly-L-Lactic Acid (PLLA) based suture thread. It is designed to provide both lifting and skin tightening as well as the stimulation of the body’s own collagen, a proven effect of PLLA.
Silhouette Soft threads have small cones which provide traction and fixation points within the dermis. The natural foreign body response reinforces this, by the build-up of new collagen formation, helping to restore a youthful appearance to the face and neck. Again, Silhouette Soft threads dissolve naturally within the skin in the months that follow treatment.

It’s thought that PDO threads are generally more effective for patients with heavier skin and greater levels of ageing and skin sagging; whereas Silhouette Soft offers superb, natural and instant results for those who have milder to moderate skin laxity, due to the delicate nature of the threads and the methods used by the doctor to insert them and mould the skin in to place.
Spring Thread is a composite implant which comprises of a substance similar to tissues found within the body, such as elastin fibres and collagen helix. It consists of a silicone matrix which provides elasticity and a polyester helix core to offer resistance and control of the elasticity. These materials are inert and completely biocompatible and have been used for over 50 years for medical implants. The threads contain cogs which point in 4 different directions, allowing for the thread to be positioned precisely and to offer a strong fix under the tissues of the skin.
Spring Thread offers the same mechanical lifting and tightening as well as the production of collagen over time. The difference with Spring Thread is that the threads themselves are permanently positioned within the dermis and will not dissolve over time, as with PDO or Silhouette Soft threads.
