Detailed answer

Sunscreen is crucial for maintaining healthy skin and preventing various skin conditions. UV rays from the sun can cause significant damage to the skin, including sunburn, premature aging, wrinkles, and even skin cancer. Sunscreen forms a protective barrier on the skin, blocking and absorbing these harmful rays. It helps to reduce the risk of sunburn, skin discoloration, and uneven skin tone. Regular use of sunscreen can also help prevent the development of wrinkles and fine lines, keeping the skin looking youthful. It is essential to apply an adequate amount of sunscreen with SPF 30 or higher on all exposed areas of the body, including the face, neck, hands, and any other exposed skin. Reapplication every two hours, or more frequently if perspiring or swimming, is necessary to maintain optimal protection. Remember that sunscreen should be used daily, regardless of the weather or season, as UV rays can penetrate through clouds and windows.
