Injectable fillers are substances that are used to replace lost volume in certain areas of the face. When used appropriately they can result in substantial and fairly long-lasting improvement. They are not replacements or alternatives to using neurotoxins as they treat different areas and problems.
- Hyaluronic Acids (Juvederm, Restylane, and others). These products are composed of a gel-like substance that is found in our bodies in between the cells. This substance is lost as we age, so one can consider this as replacement therapy in a way. These fillers are soft to the touch and are used in the lips and other areas where a softer product is needed. They do not typically last as long as some of the other fillers.
- Calcium Hydroxylapatite (CaHA) microspheres (Radiesse). This product is another naturally occurring compound in our body and has a paste-like consistency. It is used in areas where a thicker, firmer filler is needed. It has a variety of uses ranging from facial augmentation as well as for hand rejuvenation when there is too much tendon show in the hands after volume loss. Most studies have found it to last somewhat longer than the hyaluronic acid products.
- Poly-L-Lactic Acid (Sculptra) This product is a synthetic polymer that has long been used in dissolvable suture material. It works in a different manner than the other fillers: it stimulates your body to generate new collagen. It is really intended for deeper injection sites such as the cheek or temple areas and should not be used in the eyelid or lips. It requires multiple injection sessions to reach the goal of correction, whereas most of the other fillers can be used to obtain correction in 1 or 2 sessions.
- Fat grafting creates a natural augmentation for the face using your own “filler”. Fat is usually harvested from the abdomen, flanks, or inner thighs; and about one third of the volume remains after the treatment. Fat grafting can be repeated for additional fullness.
