What does a solar allergy appear like?
A solar allergy rash seems lots like different allergic reactions, because it presents within the type of itchy pink bumps (ie: hives) on all sun-exposed areas, Dr. Kim says. “In extreme circumstances, the bumps can progress to vesicles (small fluid-filled bumps) to blisters.
