We love a strange beauty secret and some of these are a little out there. And with big celebrity advocates including Kate Moss and Angelina Jolie, we can certainly get on board with these…

Snail slime

Yes, the slime that snails secrete is said to be gold standard when it comes to the fight against ageing. Everyone from Britney Spears to Kara Tointon swear by the stuff, which helps repair and regenerate. Rather than chase snails around your garden, look to Dr Organic's extensive range which claims to make you look 6 years younger in 4 weeks.

Stinging nettles

Jam-packed with nutrients and healing qualities, stinging nettles may have a bad rap but are actually very good for your skin and hair. Kate Moss is said to be a fan of beauty products containing the ingredient.

Chlorella

Sun Chlorella ‘A’ tablets are being dubbed the new Crème De La Mer but don’t carry the same celebrity price tag. Like the main ingredient of the celebrity cream, chlorella is an entirely natural and balanced, single-celled, green algae.

Chlorella is linked to healthy nails, skin and hair thanks to a combination of nutrients and amino acids. These tablets are also much easier to swallow than the nine cups of spinach (270g) you would need for the equivalent iron content or the 32oz steak you’d need to eat for that much B12!

Celery

Beyonce is said to have sworn by drinking celery seed to spring back into shape after giving birth to daughter Blue Ivy. Celery seed is said to stimulate the kidneys and push the body to flush our uric acid. Try Holland & Barrett’s Celery Seed tablets to see.

Caviar

Head to your local beauty department and try to find the most expensive item – it’ll probably be a caviar face cream. But those tiny fish eggs are rich in oil and a powerful moisturiser, which is also good for stretch marks, according to Angelina Jolie. The star used expensive Baerli sturgeon to reduce her stretch marks after she gave birth to her twins.

Seaweed

Great for hydrating skin, anti-ageing and tackling dry patches, seaweed facials were said to be the pampering treatment of choice for Kate, Duchess of Cambridge, after the birth of Prince George. Luckily you don’t have to wade into the sea to make your own – try Lancome’s Dreamtone, which works with marine extracts (including micro seaweed) to give the same effect, or The Body Shop’s Seaweed Ionic Clay Mask.

Milk

Forget pouring it on your cereal – supermodel Cindy Crawford swears by spritzing milk on her face. She’s definitely on the right track, as milk is full of minerals, calcium and protein which are all essential nutrients for super healthy skin.
