SPOTMYUV UV Detection Stickers for Sunscreen, 16-Count — Dermatrue SPF Sensor for Real-Time Reapply Alerts

SpotMyUV stickers are small, wearable UV-detection patches that visibly change color to show when your sunscreen is no longer providing protection.

Enjoying time outdoors is easier when you can visually confirm your sunscreen is still working. SpotMyUV uses Dermatrue, a patented skin-mimicking sensor, to absorb sunscreen like skin does and switch from purple to clear when the applied sunscreen is blocking UV. Worn directly on clean, dry skin and covered with sunscreen, each Spot helps you know in real time when to reapply, so you can better manage sun exposure during long days at the beach, pool, or park.

How does SpotMyUV show when sunscreen needs reapplying?

Each Spot contains a UV-sensitive layer that reacts to sunscreen absorption and UV exposure. When covered adequately by sunscreen, the sensor becomes clear in sunlight; as the sunscreen breaks down, it gradually returns to purple, signaling diminished protection.

• DermaTrue layer mimics skin absorption behavior.
• Color shift: purple (no/insufficient protection) to clear (sufficient protection).
• Visible in outdoor sunlight—color change is immediate and easy to read.
• Works with most topical sunscreens when applied over the Spot.

What’s the proper way to apply and use these stickers?

Placement and application matter for accurate feedback. Apply a Spot to clean, dry skin, press firmly to adhere, and then cover both the Spot and surrounding skin with your sunscreen. Check the Spot outdoors; if it clears, your sunscreen is applied sufficiently on that area.

• Stick on clean, dry skin—no oils or lotions underneath.
• Press edges flat to ensure waterproof adhesion during activity.
• Apply sunscreen over the Spot and the nearby skin in an even layer.
• Reapply sunscreen when the Spot returns to purple or after water exposure as recommended by your sunscreen label.

Is SpotMyUV safe for all skin types and ages?

SpotMyUV is formulated with a hypoallergenic, latex-free adhesive and has been dermatologist- and pediatrician-tested. The product is intended as a tool to visualize sunscreen performance rather than a treatment—useful for families and individuals who want an extra visual cue for reapplication.

• Hypoallergenic adhesive suitable for sensitive skin.
• Pediatrician- and dermatologist-tested for safety in use on children and adults.
• Non-invasive—worn externally and discarded after use.
• Not a substitute for following sunscreen instructions or protective clothing.

What conditions affect SpotMyUV’s accuracy?

SpotMyUV is designed for outdoor sunlight only and relies on sunscreen being applied over the Spot. Indoor light, heavy sweating under clothing, or applying sunscreen too thinly can prevent the Spot from clearing, while water exposure can shorten sunscreen effectiveness.

• Requires direct outdoor sunlight to read color change correctly.
• May not clear if sunscreen SPF is too low, expired, or applied thinly.
• Water, rubbing, and heavy perspiration can reduce sunscreen coverage and affect timing.
• Apply new sunscreen according to product directions even if Spot remains clear for extended periods.

Who is this for: SpotMyUV is ideal for families, outdoor athletes, lifeguards, beachgoers, and anyone who wants a simple visual indicator of sunscreen effectiveness. It’s especially helpful for parents checking kids’ coverage, people testing different sunscreen formulations, or those spending extended periods in the sun who want an extra layer of awareness about when to reapply.
