Aging actress Demi Moore has proved she’s prepared to go to great lengths in an effort to feel revitalised, even by Hollywood standards.

The 46-year-old has revealed she is a fan of a detox treatment that involves being covering in blood-sucking leeches.

The star, who is married to actor Ashton Kutcher, 30, recently visited Austria to receive the “leech therapy”.

She recently told David Letterman, “I feel like I’ve always been someone looking for the cutting edge of things that optimize your health and healing.”

Would you use leeches to remain youthful looking? I know I wouldn’t, that just sounds gross. I mean, she looks great, but how far do you have to go to get that look?
