Photodermatosis

Photo-dermatoses (or photo-allergic dermatoses, or photo-allergic problems) are a group of skin conditions which appear after sun exposure due to an abnormally high sensitivity to light. The causes are many and varied; diagnosis is made through questioning the patient and rigorous clinical examination, and will often require further additional investigations such as photo-biological exploration, skin histology or specific biological examinations. Treatment depends on etiology, but consists essentially in photo-protection.
