Great sunscreen!
Size: 2.5 Fl Oz (Pack of 1)
My kids used to hate putting sunscreen on, but with this one they do it without complaining. The light green color makes it easy to see, and the roll-on design is super simple for kids to use. They actually enjoy it. It feels like they’re painting their face and body, which makes it fun. The only downside is that it leaks a little.

Good protection, easy to tell where it was applied
Size: 2.5 Fl Oz (Pack of 1)
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.

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.
