Sunscreen plays a vital role in maintaining skin health. UV rays can cause blemishes, premature aging and even skin cancer. To minimize these risks, sunscreen products should be used every day, all four seasons. A product with SPF 30 and above should be preferred, especially if staying outdoors for a long time. Sunscreen can be applied under make-up or renewed throughout the day to maintain its effect. This simple habit helps to keep the skin young and healthy in the long run.
