WHAT MAKES PSORIASIS WORSE?
THERE ARE SOME THINGS that can make psoriasis worse at times. It helps to be aware of these aggravating factors. But remember, psoriasis can flare without any seeming cause. Skin injury and irritation RUBBING, SCRATCHING, AND SUNBURN could all make psoriasis worse. You should try to stop mechanically irritating your psoriasis if possible. Psoriasis can develop for the first time in sites of skin injury from cuts, burns or infections. Sun exposure FOR MOST PEOPLE WITH PSORIASIS, moderate sun exposure is very helpful, but sunburn can cause psoriasis to flare. A small number (perhaps 10 percent) of people may find their psoriasis worsens with sun exposure. If you are a fair-skinned person you may need sunscreens to protect against sunburn.
