RADIANT, luscious, gorgeous. These are just some of the words that come to mind when describing the skin of our favourite Hindi film actresses.

Must see: Madhuri, Malaika, Pooja: 35-plus and SUPERHOT!

We got celebrity skin specialist Dr Aparna Santhanam, who heads the medical services at Kaya Skin Clinic in Mumbai, tell us some of these skin secrets!

Aishwarya Rai

Rated one of the most beautiful women in the world by HELLO! magazine, this blue-eyed stunner is naturally beautiful. No matter how gruelling the shooting schedule, Ash makes sure her skin regimen is never affected.

Ash's secret: People close to her reveal that Ash is a water freak -- she drinks at least eight glasses each day, if not more. A self-confessed naturalist, Ash also relies on natural products from the kitchen -- cucumber to soothe her skin, gramflour to exfoliate and milk and yogurt to moisturise.

Dr Santhanam's tip! Sleep your way to a gorgeous, glowing skin. Lack of sleep is the cause of most skin problems -- dark circles, dull skin, pimples, you name it. Your skin thrives on oxygen, which it gets during sleep. So hit the bed at the first opportunity you get and catch up on some zzzzs.
