Sunlight can help psoriasis.
You should use a sunscreen on the parts of your skin that aren't affected by psoriasis. It's especially important to put sunscreen on your face. Some things that can make psoriasis worse are stress and infections. Some medicines can make it worse, too. Talk with your family doctor.
