SpotMyUV UV Detection Stickers for Sunscreen with Patented Dermatrue SPF Sensing Technology, Know When to Reapply Sunscreen to Help Prevent Sunburn, 16 Count

Really cool and useful product! I used these on a sunny day out and loved how they change color to show UV exposure— It actually reminded me to reapply sunscreen on time. Super easy to use and great for both kids and adults. Definitely a smart little addition for outdoor days!

Purchased for mydaughter who absolutely must wear sunscreen because of a medical condition. These work well to remind her to reapply. You can clearly see the purple color appearing and disappearing when the sunscreen is applied. They stick well as long as the skin is freshly cleaned, and last long enough for a trip out on the boat or just lounging by the pool. I'll definitely keep buying them as long as my daughter keeps using them.

I was very impressed with this UV Detection stickers. The most important thing to know about this is A. FOLLOW THE DIRECTIONS! and B. They work better with sunscreen CREAM / LOTION vs. the spray stuff. I have used it with both. The spots themselves are very adhesive (especially on clean skin) and will last a whole day of sun / water activities. I used them for our field day (I'm a teacher) and recently on a cruise vacation and if anything, they are a great physical reminder to apply sunscreen. So directions state that you must cover the spot and let it sit for 30 seconds FIRST, then rub it in with the rest of your sunscreen. Then you step out into the sun and it should change color. (I didn't realize this at first. When I was in my house, it was still purple, but it immediately changed upon stepping outside of my house.) As I mentioned, lotion works better than spray - the ones I cover with sunscreen lotion tend to get pretty clear, but spray sunscreen stays a very light purple - hence why the four stars. (If they can improve the technology to respond better to spray sunscreen, I would give it five stars! Although, maybe I should reconsider using spray sunscreen...) That is also important to remember for the level of UV protection - a sunscreen with a lower SPF will never turn your spot fully clear, you need at least a 40 to see that protection (and that is what doctors recommended anyway.) Once applied, my spot never returned fully purple - it would gradually become more of a deep magenta, but again, perhaps it was because I was reapplying. In any event, a great purple for those of us who tend to burn under the rays of the sun!

I had high hopes for this product but I don't understand fully how it should work. You open the package and the stickers are already purple even though they in a sealed package where UV rays can't hit it. Then regardless of how I put it on it NEVER goes clear. Not sure how something plastic is supposed to absorb something that is liquid?! If I'm doing something wrong then IMBTA but put it on in sun, or inside, then cover with sunscreen and it stays purple. **UPDATE** Tried again with a different sunblock and the stickers went clear. So the issue is this product doesn't work with all sunblock. It appears the Zinc based one I was using doesn't work but a spray on one that doesn't use a lot of Zinc did. Updated this review but leaving at 3 stars as I think this should be stated in the product info.

I am super pale, I used these on a 5 day cruise to the Carribean over spring break. My advice is to get them if you are super pale like me (natural strawberry blond or red heads, that shade of pale) You put the sticker on first. That is key! Then apply sunscreen. It works! I didn't burn at all. Ya'll, I didn't burn!! First time I didn't burn at all on a vacation! It was GREAT! Highly recommend.

I followed the directions. Put sticker on. Sunscreen. Expose to sun. Patch turns clear. I jump in the pool and it immediately turns purple. It was not time to reapply suntan lotion as I just applied.

These UV detection stickers are amazing! They make it so easy to know when it’s time to reapply sunscreen, which gives me extra peace of mind when I’m outside. They’re simple to use, stick well, and are great for both kids and adults. Such a smart and helpful product—highly recommend!

Works great, is a good reminder for when to reapply sunscreen!

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.

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!

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!
