Doutzen Kroes' best beauty tip is to use eyelash curlers.
The 33-year-old model - who has children Phyllon, seven, and Myllena, four, with husband Sunnery James - has found that taking just a few minutes to curl her lashes makes her look much brighter in the mornings.
She said: The best beauty tip I've learnt in my career is curling your eyelashes. Because when your eyes are tired or puffy in the morning and you curl your eyelashes it makes a huge difference.
"It was make-up artist Lucia Pieroni that taught me that."
And the little tip helps Doutzen a lot because she doesn't have a lot of time to spend on her make-up in the mornings.
She told Harper's Bazaar online: "As a mother it's very difficult to spend an hour in the morning on make-up! L'Oréal has a great BB Cream that I use and also in the summer they have one with SPF, so I wear this and mascara and that's it. The volumising Unlimited Mascara is my favourite make-up product."
But the Dutch model makes sure she takes the time to look after her skin and thinks she needs to start doing more.
She said: "I look after my skin by using SPF. I cleanse in the morning and then put on a serum, cream and SPF.
"This is something I more recently started - when you're younger you don't really care about your skin, it's just there - and as you get older you see it changing. I needed to step up my game! So I've been doing facials and masks and I look after it now."
