Suntan is a ubiquitous problem that almost everyone suffers from. It is not just a summer or beach specific problem, as sunrays can cause tanning even in cloudy weather or withindoor exposure.

Suntan is caused mainly by the ultraviolet or UV rays present in sunlight which cannot be seen by naked eyes, though visible light also contributes. These rays cause increased melanin formation and distribution in the skin which makes it appear tanned or darker.

Though tan can be removed, due to the prolonged and cumbersome nature of the process, it is preferable to use sun protection so as to prevent tan in the first place. Sunprotection includes physical barriers like umbrella, clothes, sunglasses and hats; and sunscreens to apply on exposed body parts.

For beach outings, a sunscreen with broad spectrum that covers UVA & UVB lights should be selected with an SPF rating of 30 or above and PA rating of +++ or above.

Sunscreen should be applied 10-20 minutes before going out so as to allow time for the chemicals to activate, and reapplied 3 hourly as the protecting effect declines. It is advisable to carry umbrellas and hats for extra protection as sunscreen cannot prevent sunrays entirely from reaching the skin. Protection should be taken even in cloudy weather, winter or indoor with sun exposure. Bathing and sweating can cause sunscreen to melt away faster, so selecting a non-greasy formula and repet applications are recommended strongly.

If you are suffering from tanning issues or are unable to decide a suitble sunscreen, visit a dermatologist to know your skin type and recommended products. All sunscreens in the market are not equally effective even if advertised.
