UVB rays cause which effect?

Explanation:
UVB rays produce an acute inflammatory reaction in the skin, leading to sunburn. This occurs because UVB energy is readily absorbed by epidermal cells, causing direct DNA damage and triggering inflammatory mediators that cause redness, heat, and burning sensations after exposure. Long-term effects like photoaging are mainly driven by UVA exposure, while immunosuppression and hyperpigmentation can occur with UV exposure but are not the immediate, defining response of UVB. So the effect most directly associated with UVB is photoburning (sunburn).
