What is the purpose of using sunscreen in skincare routines?

The primary purpose of using sunscreen in skincare routines is to prevent sunburn and skin damage. Sunscreens contain active ingredients that help absorb or reflect the ultraviolet (UV) rays emitted by the sun. By doing so, they provide a protective barrier that minimizes the risk of skin burns, hyperpigmentation, and long-term damage such as premature aging and skin cancer.

Regular use of sunscreen is crucial, as UV radiation can lead to DNA damage in skin cells, contributing to the development of various skin conditions and increasing the risk of melanoma. It's important to choose a broad-spectrum sunscreen, which protects against both UVA and UVB rays, to ensure comprehensive protection.

While moisturizing the skin, providing a glow, and reducing fine lines are all important aspects of skincare, they do not address the critical function of sunscreen, which is strictly to protect the skin from the harmful effects of UV exposure. Thus, the role of sunscreen as a barrier against sun damage is indispensable for maintaining overall skin health.
