Biodegradable UV-sensing patches that change color with your sun exposure
Each patch lasts 24 hours and syncs with your smartwatch to provide personalized recommendations based on your skin type and the day's UV index. No more guessing, no more accidental burns.
You look down at your wrist after a day at the beach and see your patch has turned from pale pink to vibrant magenta — your sunwatch companion app buzzes: "You've reached 80% of your daily UV limit, time to reapply sunscreen or seek shade."
