Guide
When should I think about reapplying?
For outdoor time, AAD guidance is at least every two hours and after swimming or sweating. Read the product directions as well.
The rule of thumb
The American Academy of Dermatology advises reapplying at least every two hours when you are outdoors, and right after swimming or sweating, whatever the water-resistance claim says. Your product's label may add its own instructions.
Make it part of the outing
Pack the sunscreen before you leave and tie reapplying to moments that already happen: lunch, a swim break, the walk back to the car. A reminder works better when the product is in your bag rather than at home.
Not only sunscreen
Shade, a hat and clothing do a lot of the work, especially around midday. Reapplying is easier to keep up when sunscreen is one part of the plan instead of the whole plan.
Try this
- Look at the duration of your outdoor plan.
- Pack the sunscreen where it is easy to reach.
- Review the label after swimming or sweating.
A common mistake
Assuming the morning application covers every later activity leaves the rest of the day unplanned.
