I wear sunscreen on my face, ears, and neck. Neutrogena makes a good non-greasy sunscreen and doesn't smell like you're going to the beach. I'll also wear upf sleeves in the cockpit when there is prolonged sun exposure on my side. I've had lots of pre-cancerous moles removed and I'm only in my mid 30s, so, haters can hate. I put them on when needed and taken them off before i leave the plane. No biggie.
