Why do people put on sunscreen?

Sunscreen is a product used to protect the skin from harmful ultraviolet rays from the sun. It is important to wear sunscreen to prevent skin damage, such as sunburn, premature aging, and skin cancer. Sunscreen also helps prevent sunburn and sun damage to the eyes. Sunscreen should be applied 15-30 minutes before going outside and should be reapplied every two hours, or after swimming or sweating. It is also important to choose a sunscreen that is SPF 30 or higher and is labeled "broad spectrum" to provide the best protection.
