Sun damage is a condition defined by _________.

• A. UV damage to the epidermis and dermis
• B. Sunburn
• C. Hyperpigmentation
• D. Dehydration

Answer: (A)

Sun damage comes from ultraviolet radiation that harms skin cells, especially in the epidermis and dermis. This definition focuses on the cause—UV exposure—and the layers affected, capturing both the immediate and long‑term effects, such as DNA damage, collagen breakdown, and increased risk of photoaging and skin cancer. Sunburn is an acute reaction to UV exposure, not the full definition of sun damage. Hyperpigmentation can be a sign of sun damage but isn’t the definition itself, and dehydration isn’t a direct basis for defining sun damage.
