Today at the Consumer Electronics Show, L'Oréal is unveiling My UV Patch, billed as the first-ever stretchable skin sensor designed to monitor UV exposure and help consumers educate themselves about sun protection.
 
L'Oréal's La Roche-Posay brand will offer the patch, which 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 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,” said Guive Balooch, global VP of L'Oreal'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'Oreal's U.S.-based Technology Incubator, a business division dedicated entirely to technological innovation, alongside MC10, Inc., a leading 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'Oreal 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.
 
“With My UV Patch, L'Oréal is taking the lead in developing the next generation of smart skincare technology powered by MC10's unique, stretchable electronics platform, that truly addresses a consumer need,” said Scott Pomerantz, CEO of MC10. “This partnership with L'Oreal marks an exciting new milestone for MC10 and underscores the intersection of tech and beauty and the boundless potential of connected devices within the beauty market.”
