Sun Bum kit a saver!!
Style: Mineral
Great little bag full of sunscreen for my grandson. Glad we had it to take it everywhere with us. A little pricey but he needs it so instead of taking bunches of bottles we had this.

Sunscreen is great, I would t recommend the chapstick
Style: Original
Sun Bum is hands down the best sunscreen I’ve ever used. It smells incredible, like a tropical vacation with that perfect coconut scent. It goes on smoothly, doesn’t leave you feeling sticky or greasy, and actually works! As long as I reapply every few hours, I don’t get burned, which is more than I can say for most other sunscreens I’ve tried.
The face stick is good, goes on easily, but is a little greasy feeling.
I do not like the chapstick, I can’t keep the taste of it out of my mouth and I feel like you have to put it on again and again.

Gentle protection for sensitive kids’ skin ☀️
Style: NEUTROGENA SHEER ZINC, Size: 3 Fl Oz (Pack of 1)
I’ve been trying to be more careful about what I use on my kids’ skin, and this sunscreen has been such a good find. It blends better than most mineral sunscreens I’ve tried, doesn’t have a strong smell, and feels gentle on sensitive skin. I also love that it gives solid sun protection without feeling too heavy or greasy. Perfect for beach days, playground time, or just everyday use outdoors. 😊
