L’Oreal unveiled an innovative sun product at CES (Consumer Electronics Show) last week, and everyone has been buzzing about it. Why, you ask? Because it just so happens to involve a heart-shaped temporary tattoo-like patch that will change colors during different stages of sun exposure.

The goal is to help consumers become more aware of the dangers of UV exposure, even when wearing SPF (ahem, are you reapplying as often as you should?).


My UV Patch is “the first-ever stretchable skin sensor designed to monitor UV exposure and help consumers educate themselves about sun protection.” The patch will launch in conjunction with La Roche-Posay (one of our favorite skincare brands!) later this year. For now, here’s what we know:

“The patch is a transparent adhesive that, unlike the rigid wearables currently on the market, stretches and adheres directly to any area of skin that consumers want to monitor,” L’Oreal stated in a press release.

“Measuring approximately one square inch in area and 50 micrometers thick — half the thickness of an average strand of hair — the patch contains photosensitive dyes that factor in the baseline skin tone and change colors when exposed to UV rays to indicate varying levels of sun exposure.”

It will also come with a coordinating mobile app, in which consumers will be able to upload images of their patch to be analyzed. In other words, it will show you just how much UV exposure you’ve encountered. “The key was to design a sensor that was thin, comfortable and virtually weightless so people would actually want to wear it,” stated Guive Balooch, Global Vice President of L’Oréal’s Technology Incubator.

We’re definitely excited to get our hands on this technology. As for now, the app is still in beta phase but rumor has it that My UV Patch will be free for consumers. Perhaps summer’s hottest accessory?
