In Florida, the average cost of Botox treatment is between $515 and $625. This average $12 to $15 per unit of Botox required.   However, the price of Botox will vary depending on the size of the area being treated, the number of areas receiving injections, how many units of Botox are needed to achieve the desired result, and the area that you live.  The experience level of the professional doing your treatment will also affect the cost. For example, getting injections from a cosmetic surgeon will often cost more than getting the same treatment from a specialist at a med spa.    Depending on the facility you’re getting treated at, Botox injections will either be priced at a flat rate or by the specific amount of Botox units that are required to achieve your desired affect. The latter is typically more common.
