10. Liliane Bettencourt ($ 41.5 Billion)
She’s perhaps the oldest billionaire (yet shall we say- looks like not more than 70) in our list and is also one of the only two women billionaire in our countdown. With an asset of $41.5 billion to her and her family’s name, she’s been beautifying women for the whole world her whole life. She’s the owner of L’Oreal. Having to cope with Dementia, her grandson Jean Victor Meyers now manages the company. It was her father who founded the cosmetics empire but she’s given the credit to make it go globally popular. She is however, the richest woman in Europe even after there were people who embezzled millions of Euros from her bank!
