14% is the satisfaction rate on this website from threadlifts, the lowest of any recorded category.
Comments from patients cover the gamut, from it didn't work, it didn't work long enough, facial distortion, extruding hooks, chronic pain, palpable lumps, etc. In our practice, we remove suture material from threadlifts on a weekly basis, usually while performing the facelift that patients needed initially.
Some patients do report seeing a benefit for a year, some for up to a year and a half. Some note immediate distortion and no results beyond a few months.
Why don't threadlifts accomplish the same as a facelift if they are pulling on the same tissues?
Strings placed through the tissues without any undermining tend to pull through the tissues. They do not hold up the way that undermined and fixated tissues do (i.e. during a facelift). An experienced facelift surgeon will require 20-40 sutures, placed directly in the deep tissues alone, to hold up the layer until it heals in a higher (and lifted) position. Strings are at a disadvantage because tissues are not undermined and only a few sutures are placed.
But this information is nothing new.
Patients should go into procedures with their eyes open to what the likely results are. Stringlifts do not produce facelift results.
