SPOTMYUV UV Detection Stickers for Sunscreen — 16-Count Dermatrue UV Sensor, Color-Changing Reapply Reminder

SpotMyUV are adhesive UV-detecting stickers that change color to show when your sunscreen is still protecting you and when it’s time to reapply.

These single-use stickers use Dermatrue, a skin-mimicking UV sensor developed by nanotechnology engineers to visually indicate real-time sunscreen performance. Applied to clean, dry skin and covered with your chosen sunscreen, each Spot reacts to outdoor sunlight: it becomes clear while the sunscreen is effectively blocking UV and shifts to purple as protection wanes. The result is an immediate, personalized cue so you can decide when to put on more sunscreen.

How does a Spot tell me my sunscreen is working?

Each Spot absorbs sunscreen similarly to the way human skin does, so the sticker’s color reflects actual sunscreen presence and efficacy in daylight. When the sunscreen layer on the Spot sufficiently blocks UV, the sensor clears; as the layer thins or degrades, the sensor turns purple.

• Uses patented Dermatrue nanotechnology that mimics skin absorption.
• Clear color indicates sufficient UV protection currently present.
• Purple signals diminished protection and the need to reapply.
• Works only in outdoor sunlight where UV exposure is present.

Will the stickers stay on during activity or in water?

SpotMyUV stickers are designed with a hypoallergenic, latex-free adhesive meant to remain in place through typical outdoor play and movement. They tolerate activities like swimming and sports, but adhere best when applied to clean, dry skin and covered thoroughly with sunscreen.

• Durable enough for sand play, swimming, and active days.
• Apply to dry, clean skin for strongest adhesion.
• Replace if edges peel or if the Spot detaches during use.
• Each Spot is single-use and intended for one day’s wear outdoors.

Which sunscreens work with SpotMyUV and how should I apply them?

SpotMyUV works with most sunscreens but requires sufficient application to the Spot and the surrounding skin to register protection. If a Spot never clears after application, the SPF may be too low, the product may be expired, or not enough lotion was used.

• Apply your usual sunscreen to both the skin and directly over the Spot.
• If Spot stays purple, increase the amount or check the SPF and expiration.
• Works outdoors only — indoor lighting won’t trigger reliable color change.
• Not a replacement for sunscreen; it’s a visual aid to guide reapplication timing.

Who is this for? SpotMyUV is ideal for families, outdoor workers, athletes, beachgoers, and anyone who wants a simple, visual way to monitor sunscreen performance throughout the day. Because the adhesive is hypoallergenic and pediatrician-tested, it’s suitable for children and adults of most skin types. Keep in mind these are supplemental UV sensors — use them alongside proper sunscreen routines, sun-protective clothing, and shade-seeking habits to manage sun exposure more confidently.
