What happens when we don’t wear a sunscreen?

The immediate danger of too much sun is sunburn. With repeated sun damage, the skin starts to look dry, wrinkled, discolored, and leathery. Although the skin appears to be thicker, it actually has been weakened and, as a result, it will bruise more easily. However, the sun's most serious threat is that it is the major cause of skin cancer, which is now the most common of all cancers. Doctors believe that most skin cancers can be avoided by preventing sun damage.

Why do we need to wear sunscreen?

1. The ozone layer is depleting and your body needs shielding from harmful rays.

2. Decrease the development of skin cancer.

3. It helps to prevent facial brown spots and skin discolorations.

4. It also helps to reduce the appearance of facial red veins.

5. It slows down the development of wrinkled, premature aging skin.

How should the sunscreen be applied?

Sunscreens are very effective when used properly. Follow these guidelines to give yourself the most protection:

  • Apply the sunscreen at least 20 to 30 minutes before you go outdoors, whenever you will be exposed for 30 minutes or more.

  • Reapply sunscreen every 2 hours while you are outdoors, even if the product is labeled “all-day.” If you get wet or perspire heavily, reapply sunscreen more frequently.

  • Cover all exposed areas, including your ears, lips, face and back of your hands.

  • Don't skimp; apply a generous layer. Smooth it on rather than rub it in. A rule of thumb is that 45 ml (a shot glass) of sunscreen is needed to cover all exposed skin to attain the stated level of protection.

  • Women should apply sunscreens under makeup. If you wait to apply sunscreen until you hit the beach, you may already be perspiring, and moisture makes sunscreens less effective.

What if my skin is sensitive to sunscreens

Some sunscreens contain ingredients that may irritate the skin. If you know you react to specific ingredients, be sure to check the contents on the label. You can also ask your dermatologist to recommend a sunscreen.

However, the sunscreen may not be causing the reaction. Other products that come into contact with your skin, including perfumes, certain medications, and soaps, may make your skin more sensitive. Think about the products you have been using and stop using these one by one before you stop using the sunscreen. If you are not sure about the side effects of a medication you are taking, consult with your doctor or local pharmacist.
