Botox is an injectable drug made from botulinum toxin type A. This toxin is produced by the bacterium Clostridium botulinum. Botox is used for three main purposes: muscle spasm control, severe underarm sweating and cosmetic improvement for wrinkles etc. The human lethal dose of botulinum toxin is 2000~3000 units/time. General cosmetic injection should be controlled within 200 units/time. Generally, wrinkle removal for 1 part require 10-20 units, and the full-face wrinkle removal is within 100 units. For leg slimming will require a larger amount, it is recommended to do it in stages and not more than 200 units each time, the interval should be more than 3 months. As long as the dosage is strictly adhered to the regulation and the treatments are done is proper practice or hospital, botulinum toxin injection is safe.

These side effects may take 2-4 weeks to improve as the toxin wears off.


he effects of Botox are temporary. In general, Botox lasts 3-4 months. There will certainly be patients that could last longer, in that 4-6month range, rarely 10months to a year.


As long as not too frequent and not overdose, there is no defined limit to the number of injections one site can have. However, rare cases of body’s immune system are capable of developing antibodies to the Botox molecule which can render it ineffective at some point in the future.
