Stefanie Mulic from Sweden, a Barbie-obsessed teenager had her first fillers when she was just 13 in an effort to look like the famous doll - and now spends $18,000 a year on surgery. She says her mum and aunt got her into cosmetic surgery. Since then, Stefanie has had her lips, chin, cheeks, brows and jawline altered, as well as her smile lines and her teeth done.
