Dermatologist Dr. Emma Craythorne returns for her fourth season of helping patients with unusual and sometimes debilitating skin conditions. Among the patients featured in the season premiere, “Pop Nose the Weasel,” is Leanne, who is afraid to have her 25-year-old lipoma removed. Jak’s undiagnosed skin condition has gone untreated for too long, while Trish’s nose is changing shape day by day. Another patient, Carrie, has a cyst that is destroying her confidence.
