We’re all familiar with the eye-catching MAC ads for the Viva Glam collection – the current one stars Nicki Minaj sprawled across a motorbike and Ricky Martin weightlifting a giant lipstick. But do you know what it’s all for?

Dedicated to supporting the fight against Aids, MAC set up the World Aids Fund back in 1994 and ever since they’ve made it their duty to raise both funds and awareness for this worthy cause.

Every single penny raised from sales of MAC Viva Glam products goes directly to the Aids Fund to help women, men and children affected by HIV and AIDS around the globe. But this year, on World Aids Day, MAC promises to double their impact.

On Saturday 1 December, MAC will donate the proceeds from all Viva Glam sales, and then double it.

We can't think of a better reason to do some beauty buying, so take your pick from the collection over on the MAC website and double your impact this World Aids Day.
