- Staying in the shade, especially between the sun’s peak hours (10 a.m. - 4 p.m.).
- Covering up with clothing, a brimmed hat and UV-blocking sunglasses.
- Avoiding tanning and UV tanning booths.
- Apply the sunscreen 20-30 minutes before going outside. Reapply every two hours when outside at a beach, etc. for adequate protection.
- Use enough. To ensure that you get the full SPF of a sunscreen, you need to apply 1 oz – about a shot glass full.
- Reapply after getting out of the water or toweling off. Even "water-proof" sunscreens are not usually "towel-proof".
- Use even on a cloudy day, up to 80% of the sun's ultraviolet rays can pass through the clouds. In addition, sand reflects 25% of the sun's rays and snow reflects 80% of the sun's rays.
- Don't forget to apply lip balm with SPF 15 or higher.
