The sun may be brighter, hotter and produce a painful sunburn faster from mid-morning to late afternoon, but that’s only half the battle. While skin burning UVB rays are at their peak between 10 a.m. and 2 p.m., UVA rays or “aging” rays of the sun are present from sunup to sundown and require protection all day long. Your best bet is to apply broad-spectrum sunscreen that protects against UVA and UVB rays every morning (yes, even on cloudy days) and reapply throughout the day.
