How long can the face-lift injection last?

The substance contained in the face-slimming injection is a botulinum toxin, which is mass-produced by a type of botulinum bacteria through bioengineering technology. Botulinum toxin acts primarily on muscle tissue and is commonly used in the cosmetic surgery industry to help reshape the human face. The effect of face-slimming injections is mainly to block the human nerves through botulinum toxin, thereby causing atrophy of the facial muscles. This method is currently the most effective and thorough way to slim down the face. However, the body's own immune tissue will reject and attack foreign antigens. Therefore, the effect of face-slimming injections cannot last long. Generally, one injection can only last about 3 months.

What is face lift injection?

The face-slimming injection is a botulinum toxin type A injection, which primarily acts on muscle tissue. Because it is often used to solve masseter muscle hypertrophy, it is called the face-slimming injection. The professional name of the face-slimming injection is botulinum toxin, which is a biological product that can be mass-produced through genetic engineering methods. Because of its nerve blocking effect, it is very commonly used in neurology, ophthalmology, plastic surgery and cosmetic surgery.

Face slimming injection is essentially the use of botulinum toxin injection to treat masseter muscle hypertrophy. Research has found that it is difficult to control the amount and depth of muscle resection during mandibular angle surgery, which not only results in unsatisfactory results, but also easily increases the chances of bleeding, hematoma, and infection, leading to serious complications such as facial asymmetry, trismus, and prolonged muscle spasms. In 1994, Smyth et al. reported their experience with botulinum toxin type A in the treatment of bilateral masseter muscle hypertrophy, believing that this was a revolutionary new method. Botulinum toxin injection causes the masseter muscle to atrophy and shrink by denervating the nerves, making the treatment more thorough.

The effect of face-lift injection:

The effectiveness of face-slimming injections is not 100%. For some people, after several injections, their bodies will develop antibodies against botulinum toxin, making subsequent injections ineffective. Due to chewing habits, there will still be slight asymmetry on both sides after injection. A small number of people may not be sensitive to the drug and thus the effect may not be obvious, so a follow-up visit should be conducted after 2 weeks. The effects of botulinum toxin injections on face slimming are recoverable, which means that another injection is needed after 3 to 6 months to maintain the effect.

Security

For face-slimming surgery that requires osteotomy, since the surgery is performed at the mandibular angle, it does not have much impact on the movement of the cheeks. As long as the facial nerves and important blood vessels are not damaged, there will be no side effects from face-slimming injections.

Experts say that after the injection of a face-slimming injection, the skin at the injection site will be slightly red and swollen, which will subside within a few hours. Only a few people will experience slight bruising, but it will disappear quickly, so those seeking beauty do not need to worry. In addition, the skin on the face will tighten, so for middle-aged and elderly people with loose skin, we often perform liposuction on the cheeks to tighten the skin. In addition, the contraction of subcutaneous fibers can also cause the face to tighten. Therefore, after careful deployment of face-slimming injections, there are very few sequelae.
