For most people, Botox and temporary fillers, such as Restylane, Juvederm, Radiesse, and Belotero, are the quickest and most economical way to look refreshed without significant downtime. Botox handles wrinkles that get worse with facial expression, such as frown lines between the eyebrows, crowsfeet when smiling, and forehead lines when looking surprised. Botox typically lasts for 3-4 months at a time.
Fillers serve a different purpose. Although they can be used to fill fine lines (around the mouth and between the eyebrows), they really show their strength by filling in areas of the face that start to develop deep shadows or hollows. They can be used around the eyes to alleviate dark circles or a tired look, and can be used to plump up or recontour falling cheeks or jowls. Lip enhancement is also popular.
Some fillers are liquid-like while others are very thick. Different consistencies allow treatment of all layers of the skin, from superficial to deep. Knowing the characteristics of each product allows a natural appearance to form. The longevity of these temporary fillers is anywhere from 6 months to 1.5 years.
*Blunt cannulas are new dull tipped needles that allow the fillers to be placed with much less bruising and pain than conventional needles. They have made filler treatments much more comfortable than in the past.
Finally, with regard to fillers, your own fat is the most durable and longest lived of all filler materials, lasting several times longer than these more temporary agents(see Lumen Fill).
