Polymorphic light eruption |

If sun exposure is ended, the injuries disappear in 1 to 7 days without any residual marks. It is more common in women and is usually found in the neckline. Many improve after frequent sun exposures. The responsible spectrum is UV-A, but also UV-B or a combination of both.
Both in case of minor or moderate-severe disruption, photoprotection has an important role in treating and preventing this disease, being the most efficient formulas those with a high UV-A protection. For more information consult with your specialist. |
