The average cost for Botox on RealSelf is $525. This, of course, does not explain what was treated. In the US, most practices charge by the unit (i.e. $11/ unit)or by the 'area' (i.e. $250 for the frown lines, $300 for the crows feet). You can receive great treatment, either way, as long as you are getting great results. I charge $11 per unit. This gives you the opportunity to know what it takes to get results in each area. The most common areas treated with Botox, and 'average' doses for these areas, in my practice are: Frown Lines (Glabella) 20 units. $220. Crows Feet (Obicularis) 30 units. $330. Forehead Wrinkes (Frontalis) 10 units. $110. Bunny Nose (Nasaslis) 8 units. $88. Vertical Lip Lines. (Obicularis) 5 units $55. Each patient is evaluated and the dose for each area is tailored based on the size of the muscle motion and the results of previous treatment. Most patients are very happy! Results last for an average of 4 months. This is why Botox is the number one cosmetic procedure in the US!
