Demi Moore has once again outsmarted Mother Nature and turned her haggard-nearly 50 year old mug into a glowing face that any 30 year-old would die to have.

Just 10 months ago, Demi was looking pretty rough. Now due to her obsessive beauty regime that includes loads of pricey products and treatments, rigorous diet and exercise — and even leech therapy, which she blogged about on Twitter just yesterday.

“Demi is obsessed with her looks,” one insider tells Star. “She’ll do anything to keep herself looking young.”
