India, April 30 -- This time of the year is about a lot of travel and a lot of sun tan! The sun's ultraviolet rays (UV) can damage your skin. So, skipping sunscreen is a big no! A good sunscreen can tackle sunburn, premature ageing, dark spots and decrease the risk of skin cancer. Regular use may even help maintain an even skin tone, prevent collagen breakdown and keep your skin youthful over time. The Sun Protection Factor (SPF) measures how well a sunscreen protects your skin from UV rays. As the SPF value increases, sunburn protection also increases.
