What is the role of sunscreen in skin care?

• A. To make the skin appear brighter
• B. To protect the skin from harmful UV radiation
• C. To heal existing skin damage
• D. To provide moisture to dry skin

Answer: (B)

The role of sunscreen in skin care is fundamentally to protect the skin from harmful UV radiation. Ultraviolet (UV) rays 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 or reflecting these UV rays, thereby preventing them from penetrating the skin and causing damage. This protective function is essential for maintaining skin health and preventing long-term complications associated with sun exposure. Other options, while they relate to skin care, do not specifically address the primary purpose of sunscreen. Making the skin appear brighter, healing existing skin damage, and providing moisture are benefits associated with other skin care products but do not encompass the critical protective role of sunscreen against UV radiation. Thus, focusing on that protective aspect highlights why it is essential in a comprehensive skin care regimen.
