Outdoor activity UV exposure: High Exposure time: 3 hours or more
If you will be spending long periods of time outdoors in strong sunlight, please use sunscreen with a high SPF and PA value.
Especially during hot weather, sunscreen can wash off with sweat, so reapply it every 2-3 hours.
For use in the sea or while swimming, a highly water-resistant type is recommended.

Swimming in the sea or a swimming pool, etc.
When choosing sunscreen, it's important to prioritize not only its ability to block conventional ultraviolet B rays (UVB) (indicated by SPF), but also its ability to block ultraviolet A rays (UVA) (indicated by PA).
In particular, since PA values are only displayed in four ways—"+", "++", "+++", and "++++"—during seasons with strong sunlight, you should choose a product with a higher UVB protection effect even within the same "++++" category.
