Permanent fillers are mainly used in the correction of furrows and deep depressions of the skin that are beyond the normal facial wrinkles that appear with aging. They can be an excellent option in facial rejuvenation, especially when there is need for facial and body volume restoration, such as in HIV lipodystrophy. Of the permanent fillers currently available, polymethyl methacrylate (PMMA) is the most commonly used, and has been shown to be safe, effective, and long lasting.
