Her make-up rules

Max Factor mascara “works better than really expensive ones”
It's all about a "pretty basic palette"
She avoids brown lipstick: “I think as you grow into yourself you know what works for you. So you don’t really follow trends like you do when you’re 20. Brown lipstick, I don’t think I’ll be bringing that back.”

On Restorsea

“I really loved how this [Restorsea] smelled and felt, so that’s what drew me to keep using it. Then I saw a real change in my skin. When they approached me, I thought this was fantastic."

The beauty line's USP is that it uses an enzyme from the waters of baby salmon - it keeps the skin looking dewy, apparently - and Paltrow has spoken of how she loves the fact the company was started by a female entrepreneur, Patricia Pao.

However, Restorsea is currently embroiled in a $6 million (£3.4 million) lawsuit. Pao has accused Aqua Bio Technology, which supplies the elusive salmon enzyme, of breaching an exclusivity agreement by marketing its own products, the New York Daily News reported.
