Are Skinfill fillers safe? Do doctors recommend this product?

I recently got invited to be a model in a workshop and avail free services from the beauty company "Promoitalia" in Dubai. They said they would either give me jawline fillers or butt fillers with skinfill fillers, are these fillers safe? Recommended? FDA approved? Couldn't find many reviews on this particular filler. Is it a doctors recommendation?
