Types of Anesthesia
Collagen: Because the anesthetic agent lidocaine is mixed in with collagen, additional anesthetic is usually not used. However, if you are especially sensitive to pain, your doctor may use a topical cream anesthetic or a freon spray to numb the injected area. Or, you may elect to have an injected local anesthetic or sedative drugs.
Fat: Both the donor and recipient sites are numbed with local anesthesia. Sedation can be used as well. If you elect to use sedation, be sure to arrange for a ride home after your treatment.
Dermal fillers fall into three common categories: hyaluronic acid fillers (Juvederm, Restylane, Silk, Belotero) collagen (Cosmoderm), or synthetic materials (Radiesse, Bellafill, Sculptra).
Short duration fillers last approximately 3 months while the longest lasting temporary fillers can last 5 years or more. Each type of filler has advantages and disadvantages. Which filler to use and where is best determined after consultation with your physician.
