One of my favorite Sunscreens
Style: SPF 30, Size: 3 Fl Oz (Pack of 1)
This sunscreen is great. When applying, I am very pleased at how easy it is to spread and soak into my skin. It also stays on during the day and also whenever I get in the water. I love the smell as well.

Great product. Smells like the beach. The only thing I dislike about it is that it didn’t have a safety seal.

GREAT FOR ADULTS TOO!
Style: Kids SPF 50, Size: 3 Fl Oz (Pack of 1)
This isn't just a great sunscreen for kids, it also works great for adults too. I've used this on my face under my makeup for years and it doesn't make me break out. I've tested many facial sunscreens and none of them go on as smoothly as this one. A lot of them aren't moist enough to spread out on the skin, but this one is very moist and I don't need to use a lot of it for coverage. Facial sunscreens can be pricey, but this Kids Sunscreen is under $10 and is a great value. It has a subtle, delicate scent and that's another plus for me. When it's on my face, I don't notice it. I avoid overpowering scents in all my facial products.

Moisturizing, effective, pleasantly scented sunscreen
Style: Kids SPF 50, Size: 3 Fl Oz (Pack of 1), Style: Kids SPF 50, Size: 3 Fl Oz (Pack of 1)
This is the go-to sunscreen our whole family has been using for years. It feels moisturizing (but not greasy) and is easy to rub in to avoid any kind of chalky, white residue. The scent is subtle and pleasant, not the strong pronounced sunscreen smell that a lot of others have. Best of all, it is effective! The bottle received is different than the one pictured on Amazon, but we’re not buying it for the bottle, so that’s okay. :) Would recommend.
