Skincare brand La Roche-Posay has debuted My UV Patch, the first-ever stretchable skin sensor designed to monitor UV exposure, at the Consumer Electronics Show in Las Vegas. The patch is a transparent adhesive that, unlike rigid wearables, stretches and adheres directly to any area of skin that consumers want to monitor. It contains photosensitive dyes that work with all skin tones, changing colour 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 will be available on both iOS and Android. To achieve the most accurate reading, it is recommended that the waterproof sensor be worn on the back of the hand for between 1 to 5 days. My UV Patch is expected to be made available to UK consumers later this year.
