At present, the most popular plastic surgery method is "lunch break plastic surgery", which is also called micro plastic surgery. Injection plastic surgery is also included. Many beauty lovers with Chinese characters want to know whether face-lifting needles can improve their faces. Let's take a look at the introduction of plastic surgery experts in Shijiazhuang. Women are beautiful in oval shape, and often need plastic surgery because of the hypertrophy of mandibular angle. More than 90% of beauty seekers are accompanied by benign masseter hypertrophy. The essence of face-lifting needle face-lifting is to treat masseter hypertrophy with botulinum toxin injection. Botulinum toxin injection can reduce occlusal atrophy by denervation and make the treatment more thorough. If you want to know whether the big face-lifting needle can improve the national character face, you must first understand the indications of injecting face-lifting needle, and experts have made a detailed introduction for everyone. Experts point out that people with masseter hypertrophy, not only those with mandibular hypertrophy, can do this plastic surgery. Test method of masseter muscle: bite your teeth hard. If the masseter muscles on both sides of your cheek are hard and big, it means that you belong to masseter hypertrophy. The face-lifting needle can quickly remove the ugly Chinese character face without cutting the bone with a knife. The principle of face-lifting needle is to block nerve impulses of nerves and muscles, relax over-contracted muscles and paralyze over-developed muscles. It uses paralyzed muscles to achieve the purpose of "prohibiting atrophy", thus making the originally hypertrophy muscles contract and achieving the effect of small face. The effect of face-lifting needle injection appears slowly, and it begins to appear two weeks to a month after injection. The effect can generally last about 5- 10 months. The melon face is no longer a dream, and the Chinese character face can also become a little-faced beauty. If you want to face-lift, it is a good choice to inject a face-lift needle.
