Goodbye ruby lips: Jagger opts for pink lipstick to highlight his dwindling assets

Since he is photographed so often, the gradual change has been almost imperceptible. There is, however, a dramatic contrast between the young Jagger's lips and the version pictured on stage with the band in Warsaw this week.

Such deflation - or atrophy - of the lips is inevitable with age. Indeed, the obsession of many ageing women - and increasingly men - to have collagen injections to create that bee-sting look is because we associate plumper lips with youthfulness.

'I am very proud of him and his face. He will never have plastic surgery and nor should he because facelifts on men are just yuk.'
