UV stickers are innovative decals designed to monitor and indicate levels of ultraviolet (UV) radiation exposure. Typically made from a special UV-sensitive material, these stickers change color or display a visible signal when exposed to UV light. This visual change serves as an indicator of the intensity of UV rays, helping users gauge their exposure to potentially harmful sunlight. UV stickers are commonly used for sun safety and health monitoring. They can be applied to clothing, skin, or personal items like hats and bags. Popular among outdoor enthusiasts, parents, and health-conscious individuals, these stickers act as a reminder to apply sunscreen, seek shade, or wear protective clothing when UV levels are high. The stickers are often waterproof and sweat-resistant, ensuring durability and effectiveness during activities such as swimming, hiking, or playing sports. Some advanced UV stickers can even provide cumulative exposure data, alerting users to prolonged UV exposure over time. By offering a simple, visual cue, UV stickers promote awareness and proactive measures against UV-related skin damage and health risks, making them a practical tool for anyone spending time outdoors.RECOMMENDED USE: Expose SPOT to outdoor UV light before applying sunscreen. If SPOT doesn't turn clear post-sunscreen application, SPF may be insufficient, expired, or not enough sunscreen has been applied. SPOTs work outdoors only and UV intensity impacts color change speed, so cloudy days may delay purple/clear transition. 1 PATCH A DAY: Each Patch lasts up to 12 hours. The color change will cycle ALL day with each sunscreen reapplication. You don't need to use another patch each time you reapply.
