Is there any FDA approved permanent fillers for buttocks/ hip augmentation? There is this doctor in Los Angeles Simon Ouriand who claims to have performed this procedure on celebrities like Kim kardashian and Kylie Jenner! But he won't tell the product unless you're looking to book with him!! Is there anyone here that knows what is the product used ? I would like to enhance my hips but I don't have any fat and implant are a high risk for complications so I'm looking for safe fillers. Thanks
