What is the primary function of sunscreen?

• A. Moisturizing the skin
• B. Protecting against UV radiation
• C. Exfoliating dead skin cells
• D. Enhancing skin tone

Answer: (B)

The primary function of sunscreen is to protect against UV radiation. Sunscreen is specifically formulated to absorb, reflect, or scatter the sun's ultraviolet rays, which are known to cause skin damage, including sunburn, premature aging, and an increased risk of skin cancer. By applying sunscreen, individuals can safeguard their skin from these harmful effects, making it a crucial part of any skincare regimen. The other options, while relevant to skin care, do not define the primary role of sunscreen. Moisturizing the skin pertains to maintaining hydration, which is not the purpose of sunscreen. Exfoliating dead skin cells involves removing the outer layer of dead skin to promote a fresh appearance, but this is unrelated to UV protection. Enhancing skin tone refers to improving the evenness and brightness of the skin, which is also not a function of sunscreen.
