sunscreen with SPF 30 will protect you from around 96.7% of UVB rays, whereas an SPF of 50 means protection from about 98% of UVB rays. Anything beyond SPF 50 makes little difference in terms of risk of sun damage, and no sunscreens offer 100% protection from UVB rays.

Reapplying it throughout the day is made easier with newer cosmetic sunscreens, such as brush-on powders or lightweight moisturizers with sunscreen.” Dr. Fontenot says there’s no safe amount of time dedicated to sun exposure. “The sun emits harmful UV rays all year long, even on cloudy days. Most people think they need sun exposure for vitamin D absorption, but this can be maintained with a healthy diet and vitamin supplements. And keep in mind that the sun’s rays are the strongest from 10:00 a.m. to 2:00 p.m.”
