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.


Botox vials come in two different sizes: 50-unit vials and 100-unit vials. The number of units injected depends on the number of wrinkles that want to be alleviated. This procedure should require around 20-100units. At 1 time, not more than 200 units.


Unlike botulinum toxin, no experiments have confirmed that hyaluronic acid has a potential risk to pregnant women; however, it is generally not recommended to use hyaluronic acid during lactation and pregnancy.

The effect generally begins to appear 48-72 hours after injection, obvious result should begin to be seen in about 3-7 days


Although Botulinum toxin injections are relatively safe, minor side effects are possible. These include headache, pain, swelling, or bruising at the injection site, “crooked” smile or drooling etc. Most side effects are usually temporary and should fade within a few days. These side effects may take 2-4 weeks to improve as the toxin wears off.


It is not possible to be permanent, but it would be better than single shot, the result will last much longer. Generally, to keep the result longer lasting, repeat injection every 6 months for the first 3 treatments and follow up with 9 months to a year maintenance.
