Most forms of skin cancer are linked to sun exposure, so if you wear sunscreen, it's 100 percent preventable. The problem is, if you put it on before you head outside, it's hard to remember to reapply. So the UVSunSense Wristband wants to help you remember.
This recyclable plastic bracelet monitors UVA and UVB rays. All you do is put on the wristband, and then apply a sunscreen with an SPF 15 or higher to your skin and also to the bracelet. As your sunscreen loses its effectiveness, the bracelet changes color. When it turns tan, you know to reapply, and when it turns yellow, it's time to get out of the sun. A seven-pack costs $6, which is definitely worth it since it can prevent sunburn and sun damage that can lead to skin cancer. Skin experts want to urge you not to rely on this bracelet, and to reapply sunscreen at least every two hours, even if the bracelet hasn't changed color yet.
Anything that encourages people to wear sunscreen is a plus in my book, but tell me, would you wear a UVSunSense bracelet?
