Prevention
By Mayo Clinic staffPrevention is the best way to manage polymorphous light eruption.
- Avoid the sun between 10 a.m. and 4 p.m. Because the sun's rays are most intense during this time, try to schedule outdoor activities for other times of the day. If you're unable to avoid being in the sun, limit the amount of time you're outdoors during these peak hours.
- Use sunscreen. Before spending time outdoors, apply a broad-spectrum sunscreen with a sun protection factor (SPF) of at least 15. Some sunscreens contain substances that block ultraviolet A (UVA) as well as ultraviolet B (UVB) rays. To identify UVA-blocking creams, first look to see if the product is labeled "broad spectrum." Then, look on the ingredient labels for oxybenzone, sulisobenzone, dioxybenzone, avobenzone (Parsol 1789), zinc oxide, titanium dioxide or menthyl anthranilate. A newer over-the-counter sunscreen contains mexoryl (Anthelios SX) and offers protection against both UVA and UVB radiation.
- Cover up. For protection from the sun, wear tightly woven clothing that covers your arms and legs and a broad-brimmed hat, which provides more protection than does a baseball cap or golf visor. You might also consider wearing clothing or outdoor gear specially designed to provide sun protection.
- Phototherapy. Small, incremental exposures to sunlight or UV light over the course of several weeks may prevent flare-ups prior to a winter vacation or spring season.
