Britain's Duchess of Cambridge has been treating herself to seaweed and mushroom facials.

The 31-year-old royal is being pampered at her parents' house in Buckinghamshire after giving birth to her first child, Prince George, last week and has allegedly been trying out the unusual new beauty treatment.

Catherine - formerly known as Kate Middleton - is said to be one of just a handful of celebrities handpicked to test the product before it goes on sale, the Daily Star newspaper reports.

The Dreamtone lotion, which costs £70 per bottle, took French scientists at Lancôme seven years to make and is thought to combat pregnancy miasma, freckles which can appear on new mother's complexions.

The duchess looked glowing when she emerged just 24 hours after giving birth for her big media reveal last Tuesday evening (23.07.13).

Not only was Catherine's skin radiant, but her hair was as glossy as ever when she and her husband Prince William presented their newborn son to the world.

While the brunette is renowned for her gorgeous mane, even future Queens can struggle with post-pregnancy hair, with symptoms including hair loss as well as dry and brittle hair.

Dove's new Hair Pure Care Dry Oils are perfect to help nurture post-pregnancy hair, and contain organic oils to nourish hair and give weightless finish.

Dove Hair Pure Care Dry Oils, £9.99 for 100ml it a, are now available in Boots and Tesco.
