There seem to be quite a few different types of injectable fillers available. Which ones do you think are the most promising or most efficient and what are they best for treating?
There are a number of different filler available. I personally like the Juvederm brand of fillers: Bionicam which is Juvederm Ultra, Juvederm Ultra II and Juvederm regular. They last anywhere from 6 to 12 months depending upon the individual. They are not painful to place and they do an excellent job of treating the wrinkles in the nasolabial fold area, wrinkles around the corners of the mouth and wrinkles on the lips themselves. Perlane is another very good option and it lasts in the area of approximately nine months to a year and is excellent for the nasolabial fold area and for anything around the lips. Sculptra is a deeper filler that can be used to fill out more obvious or visible depressions in the face but occasionally has been associated with some granuloma formation.
There are also a number of other fillers available but I myself do not use them and cannot speak of having much experience with them. However, I find both Perlane and Juvederm to be excellent fillers with a very good response to the nasolabial folds, or corners of the mouth and lip areas. They also work very good in the glabellar forehead region.
