Nowadays, having a small face is the goal of many MM, but want to become a small face beauty, the method is very important, otherwise not only can not achieve the effect they want, but also may be counterproductive. The first method: face slimming injection for the crowd: the jaw angle at the bite muscle hypertrophy botulinum toxin injection is through the inhibition of presynaptic membrane release of neuromediators, blocking the release of acetylcholine, blocking the nerve impulses of nerves and muscles, so that the over-contracted muscles relaxed, so that the over-developed muscles paralyzed. Long-term relaxation, paralysis, the bite muscle muscle will form a “dysfunctional atrophy”, so that the original hypertrophy of the enlarged muscle shrinkage, thus achieving the effect of slimming the face. Reminder: A-type botulinum toxin injection, although attenuated, but by no means non-toxic, must not be used indiscriminately, abuse. Inadequate injection, easily lead to bleeding, hematoma, infection, and even cause both sides of the face asymmetry, the teeth closed and a longer period of muscle spasm and other serious complications. Face slimming injection effect is also not 100%, a few people after several injections, the body will appear antibodies against botulinum toxin, making future injections ineffective.

Moreover, without the support of fat, the cheek area will age quickly. In addition, the face is predominantly muscular and the amount of fat is small. Even if fat suction is done, the result will not be good and it will easily lead to nerve and blood vessel damage.
