Putting sunscreen on kids can be a struggle. This product does many things well: easy to put on, no stinging eyes or coughing like there is with spray, provides good coverage, lasts a long time while sweating, and blocks sun well. But the really cool part is it goes on blue initially (dries clear/slightly white). This is helpful when my little one puts on his own sunscreen because it makes it easier to see the spots he missed (usually many) and helps ensure he fills in the gaps. Also great for the adults - I used it on vacation when I ran out of mine and it worked very well (great if you have arm hair too - not as sticky as many others)

Nice sunscreen, not very blue

Size: 2.5 Fl Oz (Pack of 1)

Rolls on/spreads very nicely. Not too sticky and my toddler doesn’t mind it the way she does most other sunscreens. Seems to protect well. It’s fun “blue” color is extremely faint and the product itself is closer to cloud white than sky blue. I would imagine it would barely show up at all on darker skin tones but still not complaining as she is letting me apply it despite the absence of the ‘finger painting’ I had tried to get her excited for.

Summer must have

Size: 2.5 Fl Oz (Pack of 1)

My family and I travelled to the beach this past summer. I have 2 very active kiddos and this roll on sunscreen was so helpful! It goes on quickly and has great protection.

Great sunscreen

Size: 2.5 Fl Oz (Pack of 1)

Fantastic. My kids love this product. I love that I can see where I applied, and then the blue tint completely disappears after rubbing it in. I just hope it doesn’t have some weird chemicals to accomplish this effect. It also doesn’t seem to burn their eyes.

Face sun screen

Size: 2.5 Fl Oz (Pack of 1)

This works well as far as UV protection although it does not rub in very well. It leaves your face white.
