Photosensitivity

 
Photosensitivity
A red rash that breaks out on your body during sun exposure may mean you’re “allergic” to light. According to research or other evidence, the following self-care steps may be helpful.
  • Try beta-carotene

    Increase your tolerance to sunlight by supplementing with beta-carotene

  • Shield your skin from the sun

    Steer clear of excessive sun exposure by wearing protective clothing or smoothing on sunscreen

  • Get a checkup

    Visit a qualified healthcare provider to find out if your photosensitivity is caused by a treatable medical condition or a side effect of medication

About this treatment

About This Condition

People with photosensitivity have an immunological response to light, usually sunlight. They typically break out in a rash when exposed to sunlight; how much exposure it takes to cause a reaction varies from person to person. Several conditions, such as erythropoietic protoporphyria and polymorphous light eruption, share the common symptom of hypersensitivity to light—also typically sunlight.

People taking certain prescription drugs (sulfonamides, tetracycline, and thiazide diuretics) or herbs (St. John’s wort, for example) and those with systemic lupus erythematosus have increased susceptibility to adverse effects from sun exposure.

Symptoms

Symptoms may include a pink or red skin rash with blotchy blisters, scaly patches, or raised spots on areas directly exposed to the sun. The affected area may itch or burn, and the rash may last for several days. In some people, the reaction to sunlight gradually becomes less with subsequent exposures.
