Face-lifting needle, that is, propafenone injection, mainly acts on muscle tissue. Because it is often used to solve masseter hypertrophy, it is called face-lifting needle. The essence of face-lifting needle face-lifting is to treat masseter hypertrophy by Botox injection, so that the muscles shrink and become smaller, thus achieving the purpose of face-lifting. The effect of face-lifting needle appears slowly, about two weeks to a month after injection. The effect can generally last about 5 ~ 12 months. If frequent chewing exercises such as chewing gum and knocking melon seeds are properly avoided, it can last longer. It was first used by the medical community to treat facial spasm and other muscle movement disorders. After decades of verification and improvement, the side effects of face-lifting needle are minimal and will not affect the human body.
