Since the device isn’t available just yet, remember to use sun screen.Researchers from University of Strathclyde, Glasgow have developed a skin patch that measures a person's exposure to the sun. Chemical compounds inside the patch react to ultraviolet light and change color to warn of a potential skin burn.
- Apply the sunscreen 20-30 minutes before going outside.
- 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".
- Reapply every two hours when outside at a beach, etc. for adequate protection.
- Use even on a cloudy day. Up to 40 percent of the sun's ultraviolet radiation reaches the earth on a completely cloudy day.
- Shield your eyes with UV-blocking sunglasses. Squinting caused wrinkles around the eyes. The UV rays can cause cataracts.
- Wear a wide-brim hat to help protect your head & neck.
- Don't forget to apply lip balm with SPF 15 or higher.
