Natalia Vodianova only contours her face for business meetings.

The 34-year-old Russian model has admitted she applies beauty products to enhance her cheekbones and jaw line when she has to attend a formal discussion to make her look ''older'' and ''more mature''.

Speaking to Elle.com about her beauty regime, the blonde beauty - who has starred in fashion campaigns for luxury designer brands including Givenchy, Prada and Calvin Klein - said: ''There's no particular routine. I keep my skin clean and moisturized. A product I swear by is [Guerlain] Super Aqua Serum, so maybe this is my secret.

''It's also genetics and a healthy lifestyle. I think it's really about using the right products and looking after your skin. And putting on makeup that doesn't make your skin look like it's caked on. My two favorite products are Lingerie De Peau BB Cream, and in the winter I use Météorites Baby Glow foundation. It smells so good. The pearl powder is what gives it this really incredible glow. The secret to applying my makeup is that I just put it where it's needed.

''Sometimes I wear just a little pencil and a bit of mascara to make my eyes stand out a little more. And maybe a bit of color on my cheeks. If I'm going to a meeting, I will contour my face to make myself look a little older. I have to look more mature.''

And Natalia - who has sons Lucas, 14, Viktor, nine, Maxim, two, four-month-old Roman and 10-year-old daughter Neva with her husband Antoine Arnault - has admitted motherhood impacts on her daily routine.

The Gorky-born star explained: ''Keeping up with everything I do requires some sacrifices, but once and a while I need to take some time to myself.''
