This is the first FDA approved permanent filler. It is only used for the nasolabial folds. It is a combination of Polymethylmethacrylate (PMMA) and purified bovine collagen. Because of this it requires a skin test that is read in one month.
Results are seen immediately. As the collagen reabsorbs into the dermis, the body begins to make its own to fill in the wrinkles. This gives you immediate satisfaction from the bovine collagen and the PMMA stimulates your body to make your own for a long lasting result.
