Too personal? Demi Moore tweets picture of herself in hydration mask

You can always count on Demi Moore for a few beauty tips dished via Twitter.
The actress, who has used the social networking site for everything from flaunting her bikini body to letting the world know when she's on a cleanse, revealed her latest find Monday.
"Hydration mask anyone?" she wrote, linking to a portrait of herself wearing a white, skin-tight mask.
With just her eyes, lips and part of her nose exposed, Moore's experiment could lead to softer, healthier skin.
The 48-year-old, who said the mask was "a little duty free find," has remarkably maintained a youthful appearance ? a must, perhaps, when your husband, Ashton Kutcher, is nearly 16 years younger.
