Encyclopedia > Photodermatitis

Photodermatitis is a reaction of the skin to UV rays of the sun. It may be caused by a medication that makes the skin more sensitive, a skin product (ie sunscreen containing PABA, certain fragrances), or a vitamin deficiency. Doctors can determine the presence of the disorder through a photo test.

Contents

Causes

Many medications cause sun sensitivity. Causes of photoallergy may include:

Symptoms

May result in a red, painful or itchy rash.


Prevention

Prevention includes avoiding contact with the sun:

  • Stay inside during the brightest hours of the day, from 12-3.
  • Cover up: wear long sleeves, pants, and a wide brimmed hat whenever harsh exposure is probable. Remember that a cloud cover does not afford protection from UV rays.
  • Avoid chemicals that may trigger a reaction (do not, however, stop taking medication without consulting a doctor)
  • If the symptoms are severe, see a doctor.

Foods

The following foods may also help.

  • Beta Carotene- found in carrots, not proven to be effective
  • Omega-3 Fatty Acids- found in fish and peanuts
  • Protein- will especially help individuals whose malnutrition may be a contributing factor.
  • Vitamin B3, C, D, and E
  • Green tea- antioxidants
  • Calendula

UV rays are classified by wavelength and the greater the wavelength, the greater the risk of developing photodermatitis.
While scientific studies of homeopathy specifically addressing photodermatitis have not been conducted to date, individual reports suggest that homeopathic remedies may be a useful adjunct for the prevention and treatment of photodermatitis.
Photodermatitis.html (513 words)
Photodermatitis is an itchy, scaly, blistery, reddening of the skin, caused by an increase of the skin’s normal sensitivity to the effects of sunlight or ultraviolet rays A or B (UVA or UVB).
Once photodermatitis has occurred, the basis of therapy is to minimize the inflammation in the damaged skin while treating painful symptoms as well.
Once you have had photodermatitis, your skin will be sensitive to the combination of sun and the chemical you are sensitized to indefinitely.
