Earlier this month at the Consumer Electronics Show, L’Oréal unveiled My UV Patch, a stretchable skin sensor designed to monitor UV exposure and help consumers educate themselves about sun protection. L’Oréal Group’s dermatological skincare brand, La Roche-Posay, is introducing this first-of-its kind stretchable electronic, My UV Patch. 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. 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.

Consumers will be able to take a photo of the patch and upload it to the La Roche-Posay My UV Patch mobile app, which analyzes the varying photosensitive dye squares to determine the amount of UV exposure the wearer has received. The My UV Patch mobile app will be available on both iOS and Android, incorporating Near Field Communications (NFC)-enabled technology into the patch-scanning process for Android. My UV Patch is expected to be made available to consumers later this year.

“Connected technologies have the potential to completely disrupt how we monitor the skin’s exposure to various external factors, including UV,” says Guive Balooch, Global Vice President of L’Oréal’s Technology Incubator. “Previous technologies could only tell users the amount of potential sun exposure they were receiving per hour while wearing a rigid, non-stretchable device. The key was to design a sensor that was thin, comfortable and virtually weightless so people would actually want to wear it. We’re excited to be the first beauty company entering the stretchable electronics field and to explore the many potential applications for this technology within our industry and beyond.”

My UV Patch was developed by L’Oréal’s U.S.-based Technology Incubator, a business division dedicated entirely to technological innovation, alongside MC10, Inc., a stretchable electronics company using cutting-edge innovation to create the most intelligent, stretchable systems for biometric healthcare analytics. L’Oréal also worked with PCH who design engineered the sensor. The stretchable, peel-and-stick wearable unites L’Oréal Group’s extensive scientific research on the skin and expertise with UV protection with MC10’s strong technological capabilities in physiological sensing and pattern recognition algorithms to measure skin changes over time, and PCH’s 20-year experience in product development, manufacturing and supply chain.

 “Together with La Roche-Posay dermatologists like myself, we share a mission to help increase sun safe behavior,” added Alysa Herman, MD.  “La Roche-Posay recently commissioned a global study in 23 countries, which surveyed 19,000 women and men and found a huge gap in consumer behavior: even though 92% were aware that unprotected sun exposure can cause health problems, only 26% of Americans protect themselves all year round, whatever the season. With the new My UV Patch, for the first time, we are leveraging technology to help incite a true behavioral change through real-time knowledge. ”
