Hi, I lost about 90 lbs. about 6 years ago. The first place one looses weight is in the cheeks (both pairs!) boobs and lips. I am in the medical aesthetics industry and was presented with the opportunity to have truly medical grade silicone injected into my buttocks by someone I trusted very much at no charge. I was told I could not have a reaction, and it could not move after the 72 hour...
