Do you suffer from sun eczema (Polymorphic light eruption)?
There's no cure for sun ezcema (polymorphic light eruption), but using sunscreens and being careful with the sun will help you manage the rash. Avoid the sun, particularly between 11am and 3pm when the sun's rays are at their strongest, and wear protective clothing when outdoors (unless you're hardening your skin).
Did you know that it is sometimes possible to increase the resistance of the skin with careful and gradual exposure to sunshine?
