Duchess Catherine’s beauty secrets revealed

Duchess Catherine uses the bee venom mask by Heaven in black and gold which serves as a natural, non-invasive facelift that cleanses and tightens skin. It also has a rather royal price tag at approx $316 for the black and $684 for the gold!

Deborah Mitchell's skincare products are famed for the “buzz” that surrounds them – as they containing bee venom – a natural non-invasive anti-aging alternative to botox and they've been given the royal seal of approval as a favourite of Duchess Kate and Duchess Camilla.

Camilla, the Duchess of Cornwall, pictured here with Deborah was the first to introduce her bee venom products into the royal family, speaking to Hello! Online, Deborah called her the “kindest, kindest person”.

Like Catherine, Camilla enjoys the uber-premium black and gold bee venom masks but she also loves orange flower cell renewal hydrogel and the silk skin BB cream.

Another rather POSH fan of the bee venom treatments is Victoria Beckham. Deborah says: "Victoria's been using Heaven for years and years," said Deborah. "She used the age defiance cream first and then the bee venom came along and she used that. We sent off six bottles at one time." She also likes the posh Ellajane face wipes.

Deborah says that Australia’s own Dannii Minogue, 43, " is probably my super favourite client." The pop star reportedly loves the whole line of Heaven beauty products but is particularly fond of the fragrance.

Deborah has male fans too, including Simon Cowell – whom she described as having "a very enigmatic personality," and Robert Downey Jr. who she called "really clever and really nice."
