We could have listed the Clarins sisters separately, as they're all wealthy independently of each other. All of the money came from the same place though, so we'll group them together. Twins Jenna and Prisca, along with their sisters Virginie and Claire, are worth well in excess of $2bn. If the surname seems familiar to you, it's because they're the heiresses of the Clarins brand - an internationally successful skin-care company founded by their grandfather Jacques Courtin-Clarins.
The company isn't completely in their hands yet - all four of them are currently listed as 'brand ambassadors' - but it will be one day, and at that point, they'll be even richer than they are now. Until then they have other focuses; each of them sells their own products through the brand, and they also manage the charitable arm of Clarins, which is known as 'FEED.'
