Beauty secrets of the Rich and Famous, yet otherwise without one iota of merit?

According to the US edition of Vogue, the First Lady buys a ￡215 serum which uses an extract from the stem cells of the Uttwiler Sp?tlauber apple.

The variety stays fresh for up to four months after being harvested, long after other varieties have become wrinkled.

Used in creams and serums, stem cells from the fruit are said to stimulate human skin stem cells, thereby protecting skin cell regeneration and delaying the onset of wrinkles.

It is being hailed in the cosmetic world as an exciting anti-ageing breakthrough and has been snapped up by around 100 beauty firms in Europe, Asia, and the United States, including Lanc?me and Chantecaille.
