The procedure involved to do a Botox treatment is quite simple. A very tiny needle is used to inject the Botox into the wrinkle-producing muscles. No anesthesia is required and the injections usually take only 10 to 15 minutes. There is no recovery time or down time though you may see some temporary redness or bruising at the injection site. On average, it takes three to five days to start to see an effect and up to 3 weeks to see the maximum results from Botox. Results usually last about three months.
