Why am I suddenly allergic to the sun?
Research shows that, over time, repeated exposure to UV radiation can cause the body to develop an immune response to the sun, similar to environmental pollen and hay fever. This is because sun exposure can produce changes in skin cells that the body’s immune system may identify as being foreign, or abnormal antigens.

Does vitamin C increase sun sensitivity?
Unlike hydroxyacids or retinol, vitamin C does not make the skin more vulnerable to sunburn. That being said, the most potent forms of vitamin C are vulnerable to light exposure, and therefore the use of vitamin C must be in conjunction with broad-spectrum UVA/UVB coverage.
Which is the best description of photosensitivity dermatitis?
Photosensitivity dermatitis is the name given to an eczematouseruptionarising in response to exposure to electromagnetic radiation. It is most commonly provoked by exposure to sunlight. The reaction may relate to UVB, UVA and/or visible light. It arises in all skin types.

The rashcan be provoked by as little as 30 seconds exposure to daylight, with reactions to UVB, UVA and in severe cases to visible light. In some cases it is preceded by contact allergy(especially to plants such as chrysanthemum ) or contact photoallergyor photosensitivity reaction to a drug (when it is also called persistentlight reaction).
Is there a treatment for photosensitive atopic dermatitis?
