It's good to apply sunscreen before you step out of home in the scorching sun. But don't use it too frequently or in large dabs, say experts after a recent research indicated that sunscreen use can increase the risk of skin cancer.

"Sunscreen has its after-effects as the cream has harsh chemicals that can affect the body if not applied properly," Bangalore-based dermatologist Parveen Khurana said.

"Zinc oxide, the must-have ingredient in sunscreens, can have harmful effects on the body if used frequently. Most girls today apply sunscreen every time they walk out from shade. This is a major concern," added Khurana.
