How to Reapply Sunscreen Correctly
A single morning application of sunscreen doesn't necessarily protect skin for an entire day of activity. Reapplication is part of how sunscreen is designed to be used.
When to reapply
General dermatological guidance suggests reapplying sunscreen roughly every two hours during continued sun exposure, and after swimming, sweating heavily, or toweling off — since these can reduce how much product remains on the skin.
Reapplying over makeup
Reapplying sunscreen over makeup can feel impractical. Some people use a sunscreen-focused touch-up product, a setting spray formulated with SPF, or a compact reapplication over the areas most exposed, such as cheekbones and nose. [INSERT VERIFIED PRODUCT-SPECIFIC REAPPLICATION GUIDANCE].
FAQ
If you're indoors and away from windows for most of the day, reapplication needs are generally lower than for continuous outdoor exposure — but the morning application still matters for incidental exposure earlier in the day.
