Why Should You Reapply Sunscreen?

Reapplying sunscreen is essential to keep your skin protected. Without proper reapplication, you're at risk of painful sunburns, skin damage, early aging, and a heightened risk of skin cancer.

Is it necessary to reapply sunscreen?

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 it really necessary to reapply sunscreen every 2 hours?

You really do not have to reapply sunscreen every two hours. Sunscreens are broken down by the effects of direct exposure to daylight, not by the passage of time. During an average day – a work day, let's say – the sunscreen you applied in the morning will still offer enough protection at the end of the day.
