What is the role of sunscreen in skincare?

The role of sunscreen in skincare is primarily to protect the skin from harmful UV rays. Exposure to ultraviolet (UV) radiation can lead to various skin issues, including sunburn, premature aging, and an increased risk of skin cancer. Sunscreens are formulated with active ingredients that either absorb or reflect these UV rays, thereby preventing them from penetrating the skin and causing damage.

While moisturizers are designed to hydrate the skin and some products may enhance skin color or promote collagen production, their purposes differ significantly from that of sunscreen. Sunscreen specifically focuses on preventing UV-related damage, making it an essential component of any skincare routine to maintain skin health and prevent long-term effects.
