After jawline lifting, if you don't get contouring injections, will there be a rebound effect?
Generally, after enhancing the jawline, if contouring injections are not continued, rebound may occur. The detailed explanation is as follows:

The jawline is enhanced through contouring injections. The main ingredient in these injections is botulinum toxin type A. By injecting this substance, nerve signals can be blocked, causing facial muscles to atrophy while simultaneously promoting contraction of the jaw muscles, resulting in a more defined jawline and thus achieving a lifting effect. If contouring injections are discontinued after jawline enhancement, the drug in the body will gradually be metabolized and absorbed, leading to a gradual rebound of facial fat and muscles, eventually returning the face to its original state. Therefore, discontinuing injections after initial treatment may result in rebound effects.
If you plan to receive contouring injections, it is recommended to visit a reputable hospital and choose an experienced, qualified physician to ensure optimal results. After injection, follow your doctor's instructions for proper aftercare, avoiding excessive exposure to ultraviolet light to prevent compromising the treatment outcome.
