The UV patch is a transparent adhesive containing photosensitive dyes that change color when exposed to UV rays that works with the related application to indicate varying levels of sun exposure. The technology includes an algorithm that takes into account personalized data (geolocation, phototype of skin tone, hair and eye color) to provide helpful sun safe tips, such as when to reapply sun screen, seek shade, etc. According to the L'Oréal-owned brand, its regular use has recently demonstrated that positive behavior change can be effectuated, with preliminary survey results showing that the patch use actually improves sun safer behavior and helps minimize sun burn among users:
- 63% experienced less sunburn
- 37% used more facial sunscreen
- 31% tried to stay in the shade more
Others enhancements have been made to engage the youngest users. La Roche-Posay has redesigned the app with game like features to make protecting skin fun (rather than a chore). For example, there is now an augmented reality avatar interacting with users, who earn points for each scan and can unlock prizes.
