Which statement describes sun damage?

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

Answer: (C)

Sun damage is best described as ultraviolet radiation causing damage to both the outer and deeper skin layers. Ultraviolet B rays primarily affect the epidermis, leading to sunburn and direct DNA damage that can accumulate over time. Ultraviolet A rays penetrate more deeply into the dermis, contributing to photoaging by breaking down collagen and elastin. Together, these processes explain both the acute effects like redness and burning and the chronic effects such as hyperpigmentation, wrinkles, and an increased risk of skin cancer. Dehydration, while it can accompany prolonged sun exposure, is not a description of sun damage itself, and sunburn, while a visible result of UV damage, doesn’t capture the broader, ongoing changes that UV light causes in the skin.
