Choose your provider carefully. Practitioners with minimal knowledge may perform Botox injections. Make sure the person injecting you is an expert in facial anatomy and aesthetic procedures, such as a board-certified dermatologist or plastic surgeon. The face has more than 40 muscles. Each plays an important role in creating facial expression. An inexperienced provider will be less familiar with the anatomy of the face, leading to possible complications and poor results. In fact, less experienced providers may end up using more volume of Botox (costing you more) to achieve the same result, simply because their application is less precise.
