In a brand new four-part series, eight well-loved but indisputably well worn famous faces take part in a bold and unique experiment to challenge the ageing process. Soap legend and chain smoking actress June Brown, Emmerdale and Coronation Street's Claire King, Mr Catchphrase Roy Walker, party loving EastEnders star Sid Owen, Benidorm's Sherrie Hewson, legendary rock n roller Shaun Ryder, astrologer Russell Grant and takeaway addict Googlebox star Sandra Martin are going to endure an extreme regime to see if they really can turn back time and restore their youthful good looks and all round good health.
