Think of your facial tissue like a heavy curtain that has started to sag. To hold it up properly, you need enough hooks to carry its weight. The same idea applies to your treatment.
THE FORCE NEEDED TO LIFT YOUR TISSUE
Sagging facial tissue, when you factor in normal facial movements like chewing, smiling, and talking, requires around 30 newtons of holding force to be lifted and kept in place. To put that in everyday terms, 30 newtons is roughly the force needed to lift a 3 kg bag of groceries.
WHAT EACH THREAD DOES
Specialised threads are inserted into the deeper layers of the skin and, when properly positioned, create a firming and tightening effect. For example, each individual Aptos thread can only hold 4 to 6 newtons of force. That means a single thread is not strong enough to support all of the sagging tissue on its own.
This is why your doctor needs to insert several threads working together, so that their combined holding strength meets or exceeds the required 30 newtons.
WHY THE THREADS ARE ONLY TEMPORARY SUPPORTS
The threads degrade over time and lose structural integrity, reducing their holding strength. However, threads do not need to support the tissue permanently; they serve as a temporary scaffold, allowing time for the thread materials to work and encourage new collagen production.
The absorbable materials used in Aptos threads gradually dissolve over 1.5 to 2 years, all while promoting the body’s collagen production. They maintain their holding strength for about six months, allowing sufficient time for the body to generate enough collagen to sustain the aesthetic outcomes.
THE LONG-TERM RESULT
After the threads dissolve, they leave behind a collagen scaffold that continues to support the skin as it ages. In other words, your own body takes over the job of support once the threads have done their work.
In summary, the number of threads your doctor uses is carefully calculated so that, together, they provide enough support (at least 30 newtons) while your body builds the natural collagen needed to keep things lifted for the long term.
