SPOTMYUV 16-Pack UV Stickers for Sunscreen with Patented Dermatrue SPF Sensing Technology

We read the instructions, put it on, went out and let it get some sunlight and afterwards put on the suncream. It goes transparent after putting the sunscreen, then it reappears slowly after a few hours and then we would put sunscreen again. It lasted the whole day without issues and we didn’t got burned once 😊🙏 Will but more when I run out.

Just used this product on a recent trip to Florida. I made sure to wash my skin before application and it lasted about 2 days on my skin without coming off. When out of the sun or behind uv glass, like in a car, the spot turns clear. As soon as you step into the sun it turns purple. If you use a sunblock it starts to become clear or semi clear. After being on the beach and having gone into the water a few times the spot started seeing purple and I applied sunblock again. In a minute the spot was clear again. So this is very effective In alerting me when to reapply.

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.

Got these for my cruise and I didn’t get sunburned or tanned really which was my goal. They do what they are expected to do. Fair skinned girl approved.

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!
