Choosing a sunscreen isn't a child's play. After rummaging through shelves of creams at shopping malls one often thinks if sunscreen lotions are actually effective.
When you are in the sun, especially during summers over exposure to the sunrays can cause wrinkles, tanning, and age spots.
When you buy a sunscreen, do not go on 'word of mouth'; what suits your friend may not suit you. Sunscreen lotions have two functions - sunscreen shields us from the sun's dangerous ultraviolet (UV) rays in two ways. Some work by scattering the light, reflecting it away from your body. Others absorb the UV rays before they reach your skin.
So don't get fooled by fancy brands and creative marketing, follow these pointers given by dermatologist, Dr Swati Srivastava, Sketch Clinics, Mumbai.
Any sunscreen that is labelled SPF 15 or above SPF 15 is fine for Indian skin. Buy a sunscreen that offers a broad spectrum - UVA + UVB. Here UVA stands for Ultra Violet A - is a long wave sun ray that penetrates deep into the skin, while UVB is Ultra Violet B is a short wave. A sunscreen with SPF 15 gives 94-95% UVB coverage, SPF 28 gives you 96% coverage.
According to skincancer.org, UVA rays account for up to 95 percent of the UV radiation reaching the Earth's surface. Although they are less intense than UVB, UVA rays are 30 to 50 times more prevalent. UVB, the chief cause of skin reddening and sunburn, tends to damage the skin's more superficial epidermal layers. It plays a key role in the development of skin cancer and a contributory role in tanning and photo aging.
Sunscreen contains various compounds to fight harmful sun's rays
