Agree. I agree with dr. Villaplana - just be sure to wear your sunscreen each and every time you are outdoors as uv will certainly cause a recurrence. Oh, and don't share the glass with your friend because it is contagious. If you get more than 6 outbreaks a year or the outbreaks seriously hinder your personal and professional life, see your dermatologist who may put you on daily suppressive treatment.
Yes. No contraindications off the top of my large head. Won't help it heal or make it worse. Public service announcement- drink responsibly.
