Chronic actinic dermatitis presents with itchy, flaky, redness of sun-exposed parts of face, neck and backs of hands.[3]

It occurs as a reaction to sunlight or artificial light.[3] There may be other associated contact allergies, particularly perfumes, colophony (elastoplast and pine trees), sunscreens and composite plants (daisies).[3] Diagnosis is by its appearance and pattern of behviour.[3] Photo and patch tests may identify other co-existing allergies.[3]

Symptoms and signs

It presents with itchy, flaky, redness of sun-exposed parts of face, neck and backs of hands.[3]

Diagnosis

Diagnosis is by its appearance and pattern of behviour.[3] Photo and patch tests may identify other co-existing allergies.[3]

Reactions, which vary depending on the severity of the case, include rashes, flared 'bumpy' patches, affected areas being extremely hot to touch, and outbreaks shortly (or within 24 hours) after direct or indirect exposure to UVA and/or UVB light. The skin most likely reacts on the upper chest, hands and face, however it is not unlikely for reactions to happen all over the body. The patient may feel burning, stinging or throbbing sensations in these areas, which causes mild, yet uncomfortable pain in some patients. Others liken the pain and sensation to a chemical burn that doesn't go away. It is a mistake to think that the reaction is like a sunburn, it is far deeper in the skin and often requires the use of ingestible steroids as well as topical steroids in order to alleviate the condition to a degree. The best protection is to be fully covered from sunlight, even when cloudy or hazy. The use of UV-rated clothing is suggested as well as a UV-rated umbrella for outdoors.
