The Saturday Night Live alum is famous for his sense of humor, but he wants people to know that psoriasis is no joke. Last year, he shared his story as part of the "Are You Serious?" national awareness campaign sponsored by Janssen, which makes the psoriasis drug Stelara. He also filmed several PSAs for the cause, including one that parodied Maroon 5's hit song "This Love."
"There were nights that I would toss and turn from the itchiness and pain," he wrote in a Huffington Post essay. "In the morning, I would wake up to flakes covering the bed sheets and my clothes. Everywhere I went, I left a little bit of Jon Lovitz behind… only not in a good way."
