Sir Mick Jagger is using skin cream made from caviar to make himself look younger.The 63-year-old Rolling Stones singer has reportedly been splashing out around $400.00 a time on the beauty product which is made from extracts of the delicacy - raw fish eggs. Mick's girlfriend L'Wren Scott is said to be delighted with the results. A source told Britain's Daily Express newspaper: "Mick discovered the stuff during the Stones' recent tour of the US and he's thrilled with it. L'Wren thinks it has taken years off him and Mick's now bought jars of the stuff both for himself and each of his bandmates."The protein-rich caviar in the cream is said to contain anti-aging properties which held plump the skin and relax wrinkles. Mick and Stones guitarist Keith Richards, 62, are both known for their wrinkly faces, caused by years of touring and heavy partying.
