The treatment lasts on average from 10 to 15 minutes without the need for hospital recovery or anaesthesia of any kind. The operation involves the surgeon injecting botox into the mimic muscles using a fine needle. Immediately afterwards the patient is able to resume their normal activities, needing only to be careful, for the first few hours, to avoid compressing or rubbing the area where the injection has been applied.
Although some results are visible a relatively short time after the injection (5 to 7 days), full results of the operation are evident only after about 15 days. Effects last from 6 to 8 months, gradually disappearing afterwards.
