There haven’t been many new technologies introduced into sun care in the last few decades. There was the introduction of mexoryl sunscreen in the mid 2000’s, nanoparticle sized titanium dioxide / zinc oxide and maybe aerosol sunscreens. But otherwise, there hasn’t been much new. sun-protection-patch

But this sun technology looks like it could be a neat new product for consumers who are concerned about staying in the sun too long.

Sun protection technology

Researchers at Michigan Technological University have created a sensor that tells you when it’s time to get out of the sun. The device is a nickel-sized patch that gradually darkens when exposed to UV light. When you can’t see the happy face that is on the graphic, you need to get out of the sun.

They’ve filed a patent on the technology so you won’t be able to make exactly the same type of patch but maybe you could liscence the technology. Or maybe it could be incorporated into a skin lotion that changes color.

What do you think?

    It was my understanding that P&G already owned this technology. At least i know they filled a patent to use light sensitive ink that would be applied to a sticker or added to the formula and once the organic filters were used up, the ink would react to the UV light. Its a great idea however itll be interesting to see if Michigan will get its patent through. Prehaps there is a different mechanism to their technology?
