Hello MultiMommy,At this point in time, I don't thing there is an FDA approved high volume injection material. In Europe they are using Macrolane to augment the breasts and buttocks. It is a large molecule hyaluronic acid or HA filler. Unfortunately it is not available here yet. There is some buzz about it possibly coming over here at some point. That being said, I don't really understand why one would want to use a temporary filler to augment the buttocks. In my opinion, fat and implants can be used together to get a great look. I just did this in a patient in the last 6 weeks. She had previous BBLx2 but wanted more firmness, so I placed subfascial implants. She looks fantastic.If you don't have enough fat, you could try to gain some weight prior to a BBL, or you just need to put in solid silicone implants.Good luck,Dr. Shah
