SPOTMYUVUV Detection Stickers for Sunscreen with Patented DERMATRUE SPF Sensing Technology | KNOW WHEN TO REAPPLY SUNSCREEN TO HELP PREVENT SUNBURN - 48 Count

Once I learned the trick to applying these, I love them.I apply it, then completely cover the dot in sunscreen and let that sit for 30-60 seconds. Only then do I rub in the sunscreen (and I apply sunscreen to that arm at that time). As immediately as I can, I then step in to direct sunlight. (I’m planning on testing if a UV flashlight works on the next cloudy day that I use these)I have to stand in the sun for several minutes, but the sticker will gradually turn clear.Once it’s clear I can go back and forth between sun, shade, and indoors.For me they stay on pretty well, even through sweat and oily sunscreen. I haven’t gotten in a pool or gone to the beach with one yet, though.I love these things because I always lose track of time and forget to reapply, but seeing a purple dot on my arm is an excellent reminder.

At first, I was almost convinced that this didn’t work. I put on 30 SPF before going outside and didn’t notice any change. Then, my friend put on 50 SPF and the sticker was totally clear once we got into the sun! Mine was faded a good bit, but clearly a lower SPF = less protection. It was a great indicator for when we needed to reapply and how much protection we were actually getting!

My family of red haired, pale skinned, too busy to stop people used these on our last vacation and during swim meets. No sunburns!Be sure to put in before applying lotions so they stick well.

If I could give this zero stars I would. These stickers do not work at all - myself and five others used them on a recent beach vacation and not one of the stickers changed colors as advertised. Multiple were used over five days & none worked. We even went on the company site to read the directions and watch their videos on how to use - nothing we did worked.

The spot did not completely disappear even when thick coat of sun screen. Still a good reminder. Would look for better options when i have used all of the spots

Got this for my adult son who burns very easily. He tried the stickers on a hot sunny day where he and his sister went kayaking all day. The sticker lasted all day and it really helped to remind him to put more sunscreen on. He came home happy and tired but not burnt!

You have to put the sticker first, then the sunscreen, wait 30 seconds, rub it and then go out in the sun and wait about a minute so they can turn clear. I tried these stickers with 6 different kind of sunscreens and this is what happened:Photo 1: you can see the stickers with no sunscreen. They are bright purple.Photo 2: I used one Japanese mineral sunscreen on the right and a mixed Korean D’alba sunscreen on the left. Both turned clear and as expected the mineral was thick and left a white cast. A few hours later they both were still clear. Note: I wasn’t on the beach but driving and place them on my left arm where the sun goes through the window.Photo 3: how they looked after 6 hours running errands.Photo 4: I used two different Korean stick sunscreens. Neither of them went as clear as the regular sunscreens. I wait about 3 minutes and they turned kind of clear but not as fast as the others.Photo 5: I used powder sunscreen on top of the stick on the right and sunscreen cushion on the left. The left went clear right away and the right went a little clearer but not completely.I’m very pleased that I could see the effectiveness of the products I buy.

While writing this review, I looked at the Amazon page for SpotMyUV and I took pictures of what I received. The crux of my disappointment may very well lie at easily fixable problem on the manufacturing end: IMPROVE THE INSTRUCTIONS.So, let's get on with the story.The sunspots are advertised as turning from the out-of-the-box purple (no exposure) to clear (sunscreen working) to purple (sunscreen not working).I put a sunspot on near the tip of my nose (which always gets the most sun), put sunscreen on, and waited. After 30 minutes, the spot was still purple, and I thought, "Wow, bad sunscreen lotion."So I tried another spot with a different sunscreen. Same results: after 30 minutes, the spot remained purple. What the heck. I left it on my nose and went outside.It was a clear day, not overcast at all. Most of the time was gardening full-on in the direction of the sun. At 7,000 feet, where the UV rays are almost 40% stronger than at sea level.After 2 hours, the purple finally started to fade. When I came inside after a straight 4 hours outside, the spot was clearish with purple around the edges. Ergo, ok, sunscreen must have been working at some point.The delayed feedback about whether my sunscreen was working was disturbing. The delayed feedback could lead you to believe your sunscreen is faulty when that's not at all true. So you could waste a few sunspots trying one sunscreen after the other just to get feedback (or no feedback).Now, if you haven't already, have a look at the picture I've added. You might have to Zoom in close to see everything. The Amazon page advises exposing the spot to UV *before* applying sunscreen. The package instructions? Nary a whisper about this. (Also, the package instructions are incredibly tiny and hard to read). So maybe the delayed feedback was due to not attentively explosing the spots to UV before I applied sunscreen (but why would I? There were no instructions on the package!)And now the expensive part. At this writing, the spots are $35.99 (read: $36) for a pack of 48 ($0.75/ea). You could buy 2-3 new bottles of sunscreen for that price. Assuming you or someone in your group can do basic math, you can then easily determine when it's time for more sunscreen by looking at your watch or asking someone the time.Overall, I would classify SpotMyUV and anything similar to it as a novelty. One and done.

Unfortunately we only used 2 spots from this large pack as on the first day the cleaners stole them from our hotel room. The one day we used them they were great. So much so because of these stickers we went through 4 bottles of sun cream in 9 days. They really make you aware of how quickly your sun cream comes off. We were in Turkey with temperatures of 36-40 degrees, because of these spots we didn’t burn at all. They might seem expensive but I think 100% worth it, just so you don’t burn. They go really clear where you can’t see them then bright purple. Just wish we had a chance to use them on our holiday.

So after a holiday abroad and the good weather back home, I used these every day and my LB has never burned. Pop one on in the morning before going in the sun and apply sun cream as usual and the spot will go clear then we are good to go! I wish I had know about these sooner!What I really love is that my LB is more aware of sun safety and will actually ask for more cream on if he notices the colour begin to change. Before it was like wrestling with an octopus getting him to put it on 🤣. Definitely recommend and have to my family and friends as well as anyone who asked “what is that wee spot?” 👌🏻

I tried this for my holiday this year. It did work as in it went clear then purple but it switched extremely quickly like 20mins after i lathered 50++ sunscreen on top as the instructions requested. It also does not stay on in the water which is honestly what I was looking for to know when to reapply at pool or beach. I think it would work for day walking trips or every day life but if you’re getting in water don’t even bother trying.

Recently went on holiday to Orlando where the UV levels were very high. I used these every day and I was the only one in my travel party who didn’t get burnt! Was a bit skeptical at first but definitely think they work now. Would highly recommend!

I get very bad sunburns every year. Bought these for Glasto and they were amazing. Didn’t fall off like I expected they would. Ended up giving them out to mates as well and we were all so shocked at how well they work!! Great little stickers that I’ll deffo buy again!
