Might we have just discovered Demi Moore's anti-ageing secret? The actress posted a picture of herself wearing a rather attractive moisturising face mask on Twitter.

The 48-year-old gave us an inside glimpse at her no-doubt strict beauty regime, posting the candid snap alongside the caption: "Hydration mask anyone?"

When a fan commented to ask where she got the sheet mask from, she declined to mention the exact brand name, and just replied: "A little duty free find!"

Hydrating sheet masks, such as the one Demi is so beautifully modelling, are thin strips of paper or fabric, most commonly soaked in moisturising facial products, or lined with an anti-angeing gel formula - and are renowned for their wrinkle-busting properties.

Elizabeth Arden does a full face Ceramide firming mask, to help diminish the appearance of fine lines, while Shiseido have a similar Revitalising sheet mask, to help restore skin's radiance. Givenchy's Wrinkle Correcting sheet mask also works to leave skin looking smoother, firmer and plumped from the inside.
