We can learn a thing or two from Mariah Carey.

Over the years, the singer has let us in on some of her best (and most outrageous) tips and tricks like adding mint into lipgloss for plumper lips, not showering nude and avoiding salads before a photoshoot.

Which is why our ears pricked when a new Mariah beauty trick began circulating.

While quashing one famous rumour that she only bathes in French mineral water, the singer set the record straight about her bathing habits.

When asked if she only uses mineral water to fill up her tub by The Guardian, Mariah explained “No, I bathe in milk.”

Well of course.

“Yes, sometimes I use milk as a beauty treatment,” she explained, but kept her cards close to her chest when asked to elaborate, saying, “I don’t want to give away all my secrets,” only revealing the milk has to be cold.

While it’s certainly not a conventional method (is anything with Mariah?), the skin-softening properties of milk are not something to be scoffed at.

Even Ancient Egyptian pharaoh Cleopatra, who was renowned for her stunning beauty, was said to have always bathed in donkeys milk to keep her skin soft.

But Anicent history aside, the lactic acid found in film is a proven exfoliant and great for removing dead skin cells.

“Lactic acid is a naturally occurring mild alpha hydroxy acid, which can gently exfoliate your skin while you soak,” Libby Rhee, DO, a New York City dermatologist told Well and Good. “Taking a milk bath once a week can leave your skin feeling soft, supple, and youthful.”

In addition to this, milk baths are thought to be good for treating uncomfortable skin conditions such as eczema.

The properties in milk are said to be good for soothing the irritating symptoms, particularly for children.

And while beauty retailers aren’t selling their own cartons of the white stuff beside the Cravendale quite yet, there are many brands that are wheeling out milk-based products.

Have a look at some of our faves…

Sister & Co. Almond Milk and Cardamom Milk Bath Soak, £25

Clarins Eau Ressourçante Bath and Shower Milk, £19

L’OCCITANE Milk Shea Butter Extra Gentle Soap, £9

Welda Pine Reviving Bath Milk, £8.95

Elemis Skin Nourishing Bath Milk, £29.95

But if you really want to try milk bathing à la Mariah and don’t have 20 cartons of milk to hand, you can still benefits from it by just add a few cupfuls into your normal warm bath.

Will you be swapping your water for milk?

Well if it’s good enough for Mariah…
