Would really like to try this but also super concerned at the potential for dodgy side effects that won't go away till product fades. Am I BU to think it might be a great idea? I'm relatively young but fucking miserable about my suddenly very sagging cheeks. I've got relatively weak cheekbones, my youthful bloom was all I had! Although... Have seen some cases where it is clear that someone has had this treatment (and others where you would never have known). Anyone tried this? Got any advice /words of wisdom?
