A new makeup primer has been revealed and you may already have it in your medicine cupboard

DIY beauty is only growing bigger and better by the day.

If you're a cheapskate like me, little handy tips and tricks along the way to make your makeup last longer  are always music to your ears. Suggestions for cheaper alternatives to bigger, more expensive makeup brands come in very handy, saving you a pretty penny. Sufferers of oily skin will know the importance of primer before putting on makeup, taking an extra little step which stops your makeup sliding right off your face. A few months ago we cracked the secret on using men's shaving balm to prime your chops before applying the slap and another fluid to make your makeup stay on for longer has been uncovered. The cheap primer hack has been revealed by The Daily Mail, and the even better news is that it's a household item. Many will recognise Milk of Magnesia as a medicine for treating killer indigestion and stomach ulcers, but according to celebrity makeup artist Julianne Kaye, the magical liquid also does a stellar job of keeping your makeup intact.

The fluid's high levels of magnesium break down the excess oil on your skin, giving a perfect matte veil on your face before applying makeup. Julianne recommended the unusual medicinal liquid, and often uses it over the most expensive primers on the market.

"A lot of the water-based primers on the market just feel like another moisturiser and the silicone-based primers feel waxy or, while they’ll matt you down, they still don’t stick...

"When you put milk of magnesia on your face you can actually feel that veil over the skin."

Julianne has done the faces of celebrities such as Sharon Osbourne, Scarlett Johansson and Kate Hudson so we're sure she's not talking absolute rubbish.
