(LOS ANGELES) — He isn’t a doctor, but Patrick Dempsey played one on TV, and he’s got some medical advice he’s heeding himself. 

Dempsey, who played Dr. Derek “McDreamy” Shepherd on Grey’s Anatomy, posted a selfie to Instagram showing off his blue eyes — and his checkered face mask. 

Mimicking one of his character’s catchphrases, Dempsey captioned the pic, “It’s a Beautiful Day to Save Lives,” adding the hashtags #WearAMask, #COVID19, and #YourActionsSaveLives.
