Summer light eruption

Summer light eruption, often called a sun allergy, is a local reaction that appears to be linked to UVA's. It occurs as tiny spots and red patches and may be accompanied by severe itching. It is common in the spring or during skiing holidays, when the skin is suddenly exposed to large amounts of UV rays. It particularly affects the backs of the hands, arms and neckline.
