We put some strange things on our face. Snail slime, bird droppings, milk – we’re not afraid to look to the unusual side of the spectrum in a bid for a clear, more youthful or all together healthier complexion.

And when it comes to banishing an ugly, angry spot, we’ll try anything to calm it down, including toothpaste, tea tree oil, nappy cream and even urine.

According to some experts, human urine (yes, your own wee) can cure all manner of skin conditions, from spots to athlete’s foot.

In her book Your Own Perfect Medicine, nutritional consultant and author Martha Christy champions the natural cure, outlining the healing powers of urotherapy and its anti-bacterial and anti-fungal properties.

Christy’s research found that when applied topically to the skin, urine can help decrease the symptoms of psoriasis, eczema and acne, along with fungal infections.

Loose Women's presenters Stacey Solomon, Denise Van Outen and Kaye Adams put it to the test by dabbing their pee onto their faces. Kaye said: "I can't exactly say it's knocked years off me, but it felt quite nice on my skin."

Denise revealed that her friend's mum has "been doing it for years." She said: "She swears by it! I guess all your nutrients are held in your wee."

But it’s not only good for the skin. If you’re really desperate to reap the benefits of your urine, Martha suggests gargling with it, putting a few drops in your ear and even drinking a cup of it first thing in the morning to boost your health.

Martha’s not the first person to buy into this trend. Urotherapy has been a medicinal and cosmetic treatment in Egypt, China and India since ancient times.

Madonna famously said that she keeps athlete’s foot at bay by peeing in the shower, and Bear Grylls has claimed that it can be essential for rehydration.

Urine for perfect skin? More tempting than we’d like to admit…
