The treasures hidden in beauty products
When Swiss brand La Prairie released its first caviar-based anti-ageing elixir more than 25 years ago it did so in a market not exactly populated by luxe lotions.
Today, $1000+ creams and serums containing pricy ingredients such as platinum, pearls and crushed diamonds aren't exactly rare, with entire ranges (Estee Lauder's pearl-infused Re-Nutriv for example) based upon them. Exotic ingredients are also finding their way into makeup - Rihanna boasted a 24-karat gold manicure at last year's Grammys. The cost of the enamel? US$5000 a bottle.
But precious pigments aren't exclusively the domain of prestige products: Linden Leaves puts gold in its Gold Collection of body products, Sally Hansen this year released a nail enamel containing real silver. Here's our guide to the highly prized ingredients some women choose to wear not only around their necks but also on their complexions.
