You’ll usually start to see the results from Botox within 3-5 days, but the full effect typically takes about 7-10 days to fully show. I got Botox for the first time at botox windsor ontario, and I noticed a smoothening effect after just a few days, but it wasn’t until the end of the week that I saw the full results. Botox typically lasts about 3-4 months, but it can vary depending on factors like metabolism and the area treated.
