Sunscreen is unavoidable in summers if you are going out during the day. If you have large glass windows in your home, you should try to wear sunscreen inside the house too. Wearing sunscreen protects your skin from the harmful radiations of the sun. The direct sun rays can make your skin prone to skin allergies, redness, rashes, sunburn, and even skin cancer. Not just your face, lather all your exposed areas with sunscreen lotion to avoid the harmful effects of the sun as you go out.
