In which Demi Moore and Twitter remind me to mind my mush

Confession time: I'm a bit of a Twitter addict. A Twaddict - or should that be Twiddict? - if you will.

Twitter isn't bloated with games - if I never receive another Farmville-related request from a friend on The Facebook, I will be a happy camper - or blighted by automatic daily updates of your mates' horoscopes and fortune cookies.

It's succinct. As an instant communication medium, it's useful for real-time breaking news. It's a great and often hilarious companion for telly-watching.

It's also full of celebridees, with lots of them tweeting the sort of inspirational, motivational twaddle that you'd expect to see on posters adorning the walls in The Office. Or moaning about the paparazzi invading their privacy while happily tweeting their current location and sharing the flavour of their latest fart. So I'm a bit surprised that Demi Moore, a prolific Twitter user with tendencies to over-share, is being so coy about the make and model of the one-piece white cloth hydration mask that she posed in for a candid photo.

Lookit, it's not that I believe for a second that face masks are solely responsible for her fairly incredible 48-year-old visage, but there's no denying that her skin looks good.

And besides, I'm kind of nosy.

Quizzed by one of her 3.5 million Twitter followers, Demi would only reveal that it was "a little duty free find!" and when Grazia and Look magazines and half the internet decreed it to be an SK-II Facial Treatment Mask, she again took to Twitter to exclaim that it wasn't, and at that stage I lost interest in the proceedings.

Anyway, the whole episode prompted me to dig out and use some of my own product-saturated cloth masks. Scaring the bejaysus out of small children isn't their only benefit: they're dead simple to use and fuss-free, with no danger of bits of them flaking off onto the sofa or transferring onto clothes or hair.

Mine, by an Aussie crowd called SkinVitals, were a Sephora find that you'll sometimes spot in random Debenhams and chemists, but Shiseido also do cloth masks, as do Elizabeth Arden and Olay, in their Total Effects range.
