section of the forum is dedicated to discussions addressing injectable fillers including Restylane, Perlane, Juvederm, Radiesse, Sculptra, Silicone, Artefill, or other office-based injectable filler, except for the management of acne scarring (See Acne/Acne Scarring Forum).
Some HA fillers still not FDA approved contain substances to make the HA "last longer" and create some collagen production and/or give it a different viscosity. I have noticed some contain high viscosity cross linked HA AND Hypromellose, others HA and dextranomere microspheres (DEAE Sephadex). Are those products of the same family and/or imply the same risks that acrylates (PMMA and the like)?
again, i have no idea. in only know the stuff approved in the U.S. beyond that, i don't know. read what i think about collagen production from all these HAs. in my opinion it is a bunch of crap. just do a search on it. sml
