Thank you for the question.Botox is a quick,zero downtime way of getting a more contoured,slimmer face.It is ideal for individuals with a broad,bulky lower face.The physician will assess the face ,understand the overall facial contours,the muscle bulk and size to predict the treatment effectiveness.When the Botox approx 25-30units per side is done regularly at 3-4 months interval,it will flatten out the masseter bulk and then maintenance sessions are needed about once a year.Best wishes.
Thank you for your question.Botox will obviously work and give the desired results.Yes as you get older the muscles grow more contracted and you may need a higher dose to achieve the results needed.But the results will be there for sure.All the best
