You only need sunscreen when it’s sunny
If you think you aren’t at risk for sun damage during a rainstorm, you’re wrong. No matter the season or the weather, you should apply sunscreen daily. “Ultraviolet rays that are the cause of sun damage and skin cancer are always present,” says Dr. Shilesh Iyer, a dermatologist at New York Dermatology Group. “They are independent of cold or hot weather, and are not blocked by clouds. On overcast days, only visible rays (but not UVB rays) from the sun are blocked.”
