What is a sun allergy?
Sun allergy (photodermatosis, photosensitivity) is a skin condition caused by excessive sensitivity to UV radiation. Unlike sunburn, it's the result of a misdirected immune response or an interaction with photosensitizing substances.
What are the symptoms of a sun allergy?
Redness, itching, burning, bumps and blisters that appear a few hours or days after sun exposure. The face, neck, décolleté and arms are affected most often.
What forms are there?
Idiopathic (polymorphous light eruption) – the most common form, in spring and summer. Exogenous – triggered by a medication, a cosmetic product or a plant; finding the cause is a job for your doctor. Genetic – rare inherited light-sensitivity disorders.
How do you care for skin with a sun allergy?
SPF 50+ with mineral filters all year round. Mild cosmetics without alcohol or photosensitizing ingredients. After sun: calming dermocosmetics with panthenol and ceramides.
