What is the benefit of applying sunscreen?

Applying sunscreen is essential primarily because it protects the skin from harmful UV rays. Ultraviolet radiation from the sun can lead to various skin issues, including sunburn, premature aging, and an increased risk of skin cancer. Sunscreens work by either absorbing, reflecting, or scattering UV radiation, providing a protective barrier for the skin. This defense is crucial in preventing damage that can result from both UVA and UVB rays, making sunscreen indispensable for maintaining overall skin health.

While hydration, skin healing, and exfoliation are important aspects of skin care, they are not the primary functions of sunscreen. Sunscreen's main role is specifically focused on UV protection, which is essential for long-term skin health.
