What is the purpose of dermatological sunscreen?

The purpose of dermatological sunscreen is primarily to provide broad-spectrum protection against both UVA and UVB rays. Sunscreens are formulated to absorb or reflect these harmful rays, which can cause skin damage, sunburn, and increase the risk of skin cancer. UVA rays penetrate the skin deeply and contribute to photoaging and wrinkles, while UVB rays are responsible for the surface effects like sunburn. By offering protection against both types, dermatological sunscreens help maintain skin health and prevent premature aging and other related skin disorders, making it crucial for effective sun protection.

Other products may focus on aspects like hydration or calming redness, but those functionalities do not encompass the primary purpose of sunscreen. Thus, the focus should be on its protective qualities regarding sun exposure.
