Fillers – What Are They?
Fillers are substances that are injected into the skin of the face to add volume where it has been lost subsequent to the aging process, or when it was not present in adequate amounts all along. Fillers can be classified as temporary, semi-permanent and permanent. Temporary fillers last up to about one year, semi-permanent fillers last for a few years and permanent fillers last for the life of the patient. Although it may seem best to choose a permanent filler because it does not have to be administered again, remember that the aging process is a dynamic process and that the skin will gradually thin as aging proceeds. What may look good today may be very noticeable under the skin in five or ten years.
