What is the main purpose of using sunscreen?

The main purpose of using sunscreen is to protect against UV radiation. Sunscreens are formulated to absorb, reflect, or scatter the sun's rays, which helps prevent the harmful effects of ultraviolet (UV) radiation on the skin. UV radiation can lead to skin damage, sunburn, premature aging, and an increased risk of skin cancer. By applying sunscreen regularly, individuals can significantly reduce these risks and promote healthier skin.

While enhancing skin tone, brightening complexion, and moisturizing the skin are important aspects of skincare, they do not address the primary health concern posed by UV exposure. Sunscreen serves as a vital protective barrier, making it an essential component of anyone's skincare routine, especially when spending time outdoors.
