Botulinum toxin is produced by a specific type of bacteria. Small doses are used to reduce facial wrinkles. When it is injected, it blocks certain nerve signals that make muscles contract. This makes the muscles relax, and reducing unwanted wrinkles. The effect lasts about 3–6 months on an average. After that, the muscles move again and wrinkles may come back.
WHAT’S THE PROCESS OF BOTOX INJECTIONS?
When you have botulinum toxin injected, your doctor may first rub an anesthetic cream on the area to numb it. Then he or she will inject the medicine into specific facial muscles. This only takes a few minutes, and can be done right in the doctor’s office. Ask your doctor what activities should be avoided immediately after your treatment.
Within the first week of your treatment, you should notice your muscles begin to relax, fewer facial lines, and less wrinkles. This effect wears off in about 3–6 months.
