Generally speaking, it is not allergic to face-lifting needles, but because the main component of face-lifting needles is botulinum toxin A, it is necessary to test beauty seekers before injecting face-lifting needles, and only inject them if they are not allergic. Face-lifting needle is actually biotin injection. Most people are not allergic to it. If you are not at ease, you can go to the hospital for testing. The face-lifting effect of face-lifting needle appears slowly, and it begins to appear about two weeks to one month after injection.
If people who are allergic to penicillin are injected with face-lifting needle, skin test or injection, they will have serious allergic phenomena within ten minutes. The main manifestations are chest tightness, chills, convulsions, dizziness, headache, dyspnea, cyanosis, pale face, cold hands and feet, sudden drop in blood pressure, rapid and weak pulse, and often death due to respiratory and circulatory failure if not rescued.
Face-lifting needle (botulinum toxin) is a neurotoxin, which can block the nerve impulse between nerves and muscles, relax the over-contracted small muscles, and achieve the purpose of face-lifting. In fact, beauty salons are not qualified to use face-lifting needles, and the personnel who operate face-lifting needles are not professional licensed doctors like professional plastic surgery hospitals. Even if it is the same face-lifting needle, the injection effect is different, what's more, when the essence of face-lifting needle itself is different, the consequences will often be counterproductive.
You must choose a doctor from a regular hospital to do the face-lifting needle, so the effect will be better.
