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.

The best for sensitive skin and sensitive noses
Style: SPF 50, Size: 5 Fl Oz (Pack of 1)
This is the absolute best sunscreen I have found for my super reactive sensitive skin. I have never had any issues with this sunscreen and it prevents sunburn well. I am also super sensitive to smells and this doesn’t smell like anything to me. It gives a really pretty glow to your skin as an added bonus.
