Renee Zellweger

As opposed to her Bridget Jones' character who is not a bit bothered of her plump, unattractive appearance, the radiant Renee Zellweger undergoes a meticulous beauty regimen to keep her skin glowing -- fit for the elite Hollywood A-listers.

A source close to the star was quoted by the Daily Mail, as saying "Renee may have perfect skin now but it hasn't always been that way."

Well any glamorous star knows better. Before every glitzy screen and gala calls, the Oscar-winning actress reportedly submits herself to a 60-minute 'microdermabuffing' session, described as 'sand-blasting for the face'. This rather strange biochemical facial routine is designed to rid the skin of any blemishes, resulting to a healthy-looking, luminous skin.
