INJECTIBLE FILLERS: In this injection procedure, fillers are injected into the face to fill in creases, or to add fullness to the lips or cheeks. The most common fillers used are collagen, alloderm, and fat harvested from the patient’s own body. Permanency of the results varies from patient to patient. The anesthetic lidocaine is mixed with collagen before implantation, so no further anesthesia is usually necessary. For fat injections, the donor and recipient sites are numbed. Sedation may be used with both types of filler procedures. Meet with our friendly staff in the Baltimore / Timonium area to learn whether lip injection treatment is right for you.
