Demi Moore was seen this week leaving the Cryohealthcare Clinic in Los Angeles, which specializes in skin care and anti-ageing procedures.

Demi More looked fantastic and was sporting a flawless complexion, opting for casual red trousers, black top and denim shirt.

Various treatments are on offer at Cryohealthcare – but a popular one includes the Whole Body Cryotherapy (WBC).

The customer stands in a chamber, where they are blasted with icy cold air – with the clinic’s website claiming the procedure helps to increase the production of collagen and so reverse skin ageing and appearance on cellulite.

The cold also forces the body into producing heat – and so increases metabolism – with claims it can result in burning between 500 and 800 calories after a session.

A host of celebs use the procedure to rejuvenate their skin – but it is also used to help with injuries, as it triggers an anti-inflammatory response.

Dancing With The Stars contestants and professionals, including Katherine Jenkins and Derek Hough, are among the big names to have used the system to treat dancing injuries. The practice was first used in Japan in 1978 to treat rheumatoid arthritis.

On Sunday, Demi Moore will turn 50 after a whirlwind year which has seen her enter rehab and come to terms with her split from Ashton Kutcher.
