The Hollywood icon previously said she relies on a combination of daily sunscreen, multi-tasking makeup and beauty supplements to maintain her flawless visage.

'As a fair-skinned girl, I've worn sun cream since I was a kid,' she told Harper's Bazaar.

Nicole is a fan of Neutrogena Ultra Sheer Dry-Touch Sunscreen Broad Spectrum SPF100+, which she uses on her face every day, even if it's cloudy.

She is also strict about taking her makeup off and double-cleansing every night.

But if she is having a late night or has been travelling, Nicole isn't averse to using a simple cleansing wipe in order to make things quick and easy.

The Hours star also likes to mix high- and low-end skin products.

'La Mer creme is my go-to, but I also love Aquaphor. It costs nothing,' she told Allure.

The actress mixes and matches the $250 moisturiser with the budget staple in order to get her dewy look.
