Low blood flow: Probably low blood flow to that area. He can put a warm (not too hot) wet wash cloth on the area and it will slowly pink up again. If it doesn't he should talk to a doctor. If he's a smoker he should stop. When he's going to out in the cold he should apply lip balm and cover the are with a scarf, turtle, or other winter gear.
