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 excited to find these stickers after having surgery for melanoma this year. Make sure to read the directions completely and carefully before use. They can be tricky to use if the directions aren’t followed exactly. The sticker didn’t work as well on my 11 year old as it did on my adult friend because of the multiple step directions. They are on the expensive side and for how they worked it would be helpful to have a better price point. You may go through quite a few with little ones and it would get expensive to keep buying these.

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!

These stickers are easy to use and very helpful for knowing when it’s time to reapply sunscreen. They give extra peace of mind, especially at the beach or pool. A smart little product for anyone who wants better sun protection.

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!
