Each click simulates 15 minutes of sun exposure
UV Protection: 100% - Safe!
The ReefRanger uses UV-sensitive photochromic dyes that change color as sunscreen degrades. Once protection drops below safe levels, micro-encapsulated wasabi essence is released through your pores, creating a gentle tingling sensation that reminds you to reapply. The device continues monitoring for 8 hours on a single application.
