It is not necessary to wear sunscreen during recreational activities when it is indoors. Therefore, option D is correct.
Sunscreen shields keep skin safe. They are crucial in preventing the skin from absorbing ultraviolet (UV) radiation. Sunburns and skin cancer are both caused by UV radiation, which also affects the skin.
Your elastin, collagen, and skin cells can become damaged from repeated sun exposure with little to no protection. This can eventually result in early ageing symptoms such as discolouration, wrinkles, fine lines, and a leathery appearance. People who spend time in the sun without protection, especially those in their 20s and 30s, are more likely to experience photoaging, or premature ageing. Thankfully, consistent sunscreen use can avoid these skin problems.
