Do you really need to reapply sunscreen every 2 hours?
Do you really need to reapply sunscreen every 2 hours? Generally, sunscreen should be reapplied every two hours, especially after swimming or sweating. If you work indoors and sit away from windows, you may not need a second application. Be mindful of how often you step outside, though. Keep a spare bottle of sunscreen at your desk just to be safe.
Is SPF 50 overkill?
Properly applied SPF 50 sunscreen blocks 98 percent of UVB rays; SPF 100 blocks 99 percent. When used correctly, sunscreen with SPF values between 30 and 50 offers adequate sunburn protection, even for people most sensitive to sunburn.
Do you still tan with SPF 50?
With SPF 50, 2% of UV rays are able to penetrate the skin. That's how you're still able to get a tan even with a high SPF. So in order to prevent yourself from sun damage, you need to reapply at least every two hours.
