In brief: Damage>Vasodilation

The ultraviolet frequency photons involved are skin damaging, upper 1/2 of uv ionizing (like x-ray).
Tanning: a slow, delayed protective response to ? future skin damage. The immediate response to the cellular damage from absorbed uv radiation is arteriolar dilation to ? capillary flow (visible as ? pink color) to help remove damage & facilitate cellular repair & perceived as itchy, pins. Needles.
