Causes of Psoriasis Directory
Psoriasis isn't contagious, so you can't get it from someone else who has it. In some cases, it runs in families and parents can pass it to their children. Experts believe psoriasis is caused by an overreaction of the immune system that causes the inflammation and flaking of skin. People with psoriasis may notice that certain things trigger a flare, like smoking, drinking alcohol, or allergies. Find more information about what causes psoriasis.
