Function: Botox injections work by weakening or paralyzing certain muscles or by blocking certain nerves. The effects last about three to twelve months, depending on what you are treating. The most common side effects are pain, swelling, or bruising at the injection site. You could also have flu-like symptoms, headache, and upset stomach. Injections in the face may also cause temporary drooping eyelids. You should not use Botox if you are pregnant or breastfeeding. Description: Botox is the brand name for botulinum toxin type A, a naturally occurring, highly toxic protein that is injected into the skin - in very tiny doses - as a therapeutic or cosmetic procedure. When Botox is used as a wrinkle cure, it works by blocking nerve impulses to certain muscles, causing them to relax and the facial lines they control to gradually disappear. Effect: The curative effect usually begins to appear 48 to 72 hours after the injection, and the facial wrinkles become shallow and flat, and the skin becomes smooth. However, due to its mechanism of action, the duration of treatment is usually 3 to 6 months, with an average of 4 months, and a very small number can be extended to 10 months or even a year. To maintain efficacy, repeat injections should be repeated around 6 months to reduce antibody production. After 2 to 3 consecutive injections, the effect of each injection can last for 6 to 9 months, or even longer. This change process should clearly inform the subject to obtain the cooperation, which is conducive to enhancing the curative effect.
