SpotMyUV UV Detection Stickers for Sunscreen with Patented Dermatrue SPF Sensing Technology, Know When to Reapply Sunscreen to Help Prevent Sunburn, 48 Count

What more do you need for the lake or the beach for the kids or yourself.

Followed the directions and had zero issues. Used in Mexico and came back to the states with barely a tan.

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 got these for a music festival as I'm fair skinned and burn easily. I figured that being out in direct sunlight in weather with an 8/10 UV rating they would help. They absolutely did not. I still ended up reapplying sunscreen without paying attention to the dot. Even after having it in for 6hrs it never changed color. I ended up getting burnt on the 1st day waiting to be told it was time. I did have a base tan and used sunscreen regardless. It's my fault for getting burned as I should've just reapplied when I saw the sticker not responding. Very unhappy with this product and both sets are being returned.

Work great if you use the right

Absolutely love these and use them all the time. I would recommend to anyone to use them!

Very cool product, and they stick on pretty well!
