Botox is a medicine used for face-lifting acupuncture. Botox is very commonly used in neurology, ophthalmology, plastic surgery and cosmetic surgery because of its nerve blocking effect. The dose used for face-lifting is only 1% of its maximum safe dose, which is very safe. As an intramuscular injection, botulinum toxin has no obvious side effects. Now it has been widely used as a face-lifting injection.
