"Expert-Recommended Sunscreens for Indoor and Outdoor Protection"
Wearing sunscreen indoors is recommended as UV rays can still penetrate glass windows and cause skin damage and premature aging. Opt for a sunscreen that’s at least SPF 30 and apply it to all areas of exposed skin including your neck and hands. Reapply every two hours and definitely re-apply sunscreen if you sweat, wash your face, or wipe your face for any reason.
