Tensor threads: an aesthetic medicine technique that has evolved since the 90s
Tensor threads are medical devices used in aesthetic medicine to treat sagging skin and restore a more youthful appearance to the face. Since their appearance in the 1990s, they have undergone numerous technical developments and still give rise to debate today regarding their effectiveness and safety.
Absorbable vs. non-absorbable threads: what are the differences?
There are two types of tensor threads: resorbable threads and non-absorbable threads. The first are made of a biodegradable material, such as polylactic acid or polydioxanone, which gradually dissolves in the body. They generally last from a few months to two years depending on the product used. The latter are made from non-degradable materials, such as polyester or silicone, and can stay in place indefinitely.
According to Dr. Cédric Kron, plastic surgeon specializing in aesthetic medicine, “resorbable threads present less risk of infection or inflammatory reaction than non-resorbable threads.” However, he also emphasizes that “their lifting effect is less lasting”. Dr. Jean-Louis Sebagh, another expert in aesthetic medicine, confirms this opinion and specifies that “non-absorbable threads may be more suitable for patients with significant skin sagging”.
Mode of action of tensor threads: how does it work?
Tensor threads act according to two principles: mechanical traction and biological stimulation. Mechanical traction involves straightening and supporting sagging tissues by implanting wires under the skin. The latter are equipped with small cones or hooks which allow you to hook the dermis and pull on it to obtain a lifting effect.
Biological stimulation, for its part, is based on the capacity of the tensor threads to cause a controlled inflammatory reaction in the dermis. This inflammation stimulates the production of collagen and elastin by fibroblasts (cells responsible for protein synthesis in the dermis), which improves the elasticity and firmness of the skin.
Progress of the sessions: how does the installation of tensor threads work?
The placement of tensor threads is generally carried out in a medical office under local anesthesia. The practitioner begins by making a marking on the patient’s face in order to determine the areas where the wires will be implanted. He then makes a small incision in the skin to insert a needle equipped with a tensioning thread. The needle is removed, leaving the thread in place under the skin.
The number of threads used varies depending on the patient’s needs and the extent of skin sagging. A session lasts on average 30 minutes to an hour and the results are visible immediately after installing the threads. The after-effects of the operation are generally simple, with edema and bruising which disappear after a few days.
Potential benefits depending on age and skin type
Tensor threads can be adapted to different types of patients depending on their age and skin type. According to Dr. Kron, “Patients between the ages of 40 and 60 are most likely to benefit from the benefits of tension threads.” He adds that “people with thin skin or significant loss of elasticity may also benefit from this technique.”
Questions about the effectiveness and safety of tensor threads
Although opinions are divided as to the actual effectiveness of tightening threads, some experts believe that they do not replace surgical techniques such as head and neck lifting to treat significant skin laxity. Dr Sebagh specifies that “the results obtained with tensor threads are less spectacular than surgical intervention but they make it possible to significantly improve the appearance of the face without going through surgery”.
Concerning safety, tension threads are generally considered a minimally invasive and well-tolerated technique. However, complications can occur, such as infections, allergic reactions or migration of the thread under the skin. It is therefore essential to choose an experienced and qualified practitioner to carry out this type of intervention.
Costs associated with tensor wire placement procedures
The cost of a tensor thread installation session varies depending on the number of threads used and the type of thread chosen (absorbable or non-absorbable). On average, it costs between 1,000 and 3,000 euros for a complete intervention.
Conclusion: a critical overview of tensor threads in aesthetic medicine
Tensor threads represent an interesting alternative to cosmetic surgery to treat sagging facial skin. However, their effectiveness and durability depend greatly on the type of thread used and the skills of the practitioner. It is therefore appropriate to carefully evaluate the potential benefits according to age and skin type as well as the associated risks before considering this solution.
