Anything with Cara's name (or face) on it sells, fact. And the French fashion house knows it. This weightless fusion foundation promises even coverage for up to 24 hours and will retail at £30 when it goes on sale the 10 August - a relatively small price to pay for looking like the hottest model on the scene.
Plus, it contains lipophilic active, a microscopic material which truly makes it 'space age' beauty stuff.
Lloyd Simmonds, the brand's creative director for beauty says: "It has a natural-looking, mattifying effect on the skin - without appearing dry or caked on.
"There's definitely more matte to the finish than radiance, compared with our other foundations. And it lasts the entire day."
As for the women Simmonds sees wearing it? "This foundation responds to modern women's lives and how they don't necessarily have the time anymore to invest in a long, drawn-out beauty regimen.
"It has to be quick and easy. That's what women want."
Luxe, long-lasting and easy to apply? That's what we're talking about. If you haven't put your name down for this new YSL foundation, get on the case.
