Polymorphous Light Eruption. People with a sensitivity to sun exposure will develop this rash a few hours or few days after being exposed to the sun. Raised bumps usually appear on exposed areas such as the face, upper chest and parts of the arm and legs. PMLE generally occurs in spring or summer when those who are sensitive start spending more time in sunlight. It usually resolves itself with no treatment.
