There are a number of wrinkle filler products available with different characteristics. I will mention them in order of longevity.
The first group are the Hyaluronic Acid products. There are a number of products containing this material. These include:
Rastylane, Perlane, Elevess, Prevelle, Hylaform, Juvederm, and Captique
The differences in the products are subtle despite claims made by the manufacturers. The newest products are Elevess and Prevelle. These 2 contain a numbing medicine that decrease the discomfort associated with the procedure.
All the products mentioned above last about 6 months despite claims to the contrary by the manufacturers. And they are avaiable off the shelf with no preparation.
Other types of fillers include Radiesse and Sculptra. These are also available off the shelf with no preparation.
Radiesse is a hydroxyapatite product (similar to the material found in bone) and lasts about 8-9 months.
Sculptra is a poly-L-lactic acid product (similar to suture material used in surgery) and lasts about 2 years. This is more of a volume filler than a wrinkle filler.
All of these products can be used to effectively in the face. However, as mentioned, all of the products listed above are temporary fillers.
The only FDA approved permanent filler that is available off the shelf is Artefill. This product can improve wrinkles permanently with excellent results.
Last but not least is fat injections. Fat injections can also permanently add volume to the face. Although this is a surgical procedure, with proper technique excellent results can be achieved.
