(Mira Miller/ Very Well Health) — Sunscreen is a vital component when it comes to preventing sun damage and skin cancer, but misconceptions abound when it comes to proper application. One of the most common myths is that you only need to wear sunscreen in the summer, but you should be wearing it year-round, actually.
