We must first look at what this beauty needle is. At present, the mainstream cosmetic injection materials in China are mainly hyaluronic acid and botulinum toxin, both of which can play a certain role in wrinkle removal and anti-aging, and botulinum toxin can also play a role in face-lifting. As for whether these two injections will cause facial stiffness, we can look at them separately.
1, botulinum toxin
Botulinum toxin is actually a neurotoxin and is recognized as one of the most toxic toxins in the world. Its application in medical beauty is to use its nerve paralysis characteristics to perform operations such as wrinkle removal and face reduction.
Professor Pingjiang, deputy director of plastic surgery in Southern Hospital of Southern Medical University, pointed out in an interview that the botulinum toxin used in medical beauty has been diluted and the dosage is very small. As long as it is injected under the guidance of regular hospitals and doctors, the safety is guaranteed.
As for Cheng Lisha's inability to smile after injection, Professor Pingjiang thinks it is possible. "Because botulinum toxin has certain toxicity, if the dose control is not good or the injection skills are not in place, it may lead to facial muscle paralysis of beauty seekers, which is characterized by stiff face, unnatural smile and inadequate expression management. This situation is avoided by experienced doctors as much as possible, and even if it happens, it can naturally recover after a period of time. "
2, hyaluronic acid
Hyaluronic acid is a natural physiological component of human body and has a good moisturizing effect. If it is injected into the face manually in the later stage, it can smooth the sunken wrinkles and fill the face according to the different injection sites and doses. Common items include hyaluronic acid wrinkle removal and rhinoplasty.
According to Professor Pingjiang, as hyaluronic acid is an inherent component of human body, as long as hyaluronic acid products are qualified, there will be no allergic and rejection behavior.
"The common side effects of hyaluronic acid are mostly manifested as vascular embolism, that is, hyaluronic acid blocks blood vessels, which can lead to serious consequences such as tissue necrosis and blindness. However, this situation is more common in illegal institutions, and the operators are mostly non-professional doctors. "
As for facial stiffness, Professor Pingjiang said that this is not a side effect caused by hyaluronic acid. Of course, if you inject too much hyaluronic acid during filling, it may lead to excessive fullness of the face and even look "plastic", but it will not affect normal expressions such as smiling.
Generally speaking, injection cosmetology is a safe and effective cosmetic method, and facial stiffness is a small probability event. If the beauty seeker chooses an experienced and aesthetic plastic surgeon, such a situation can be avoided as much as possible.
