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.

Great Mineral Facial Sunscreen
Size: 1.7 Fl Oz (Pack of 1)
This is the best mineral facial sunscreen I’ve used. It comes out as a thin lotion that spreads easily. I have used two other brands and considered a brand that was expensive before trying this. I liked baby bum mineral 50 sunscreen lotion for the body and decided to give this a try. I like sun bum products. They tend to make effective products that are not too expensive. The zinc oxide mineral facial sunscreen I was using slightly irritated my skin and felt heavy like a mask after applying. It left a greasy residue on my face. This sun bum facial mineral sunscreen is non-irritating and feels very light like a chemical-based facial sunscreen. It leaves no residue on the skin. I prefer zinc oxide mineral sunscreen because it’s natural, safe and effective. Some zinc oxide mineral sunscreens put a white caste on the skin after application. The titanium dioxide and zinc oxide blended mineral sunscreens are worse due to the titanium dioxide. Titanium dioxide is a bright-white powdered substance, and I have not experienced any product with this ingredient that doesn’t appear white on the skin and cannot be blended. This sun bum zinc oxide mineral facial sunscreen has no white caste. Like another reviewer, I also hope that sun bum continues to make this facial mineral sunscreen indefinitely. It’s the best I’ve ever tried and at an excellent price point. If you like mineral sunscreens due to the health and environmental concerns with chemical-based sunscreens, try this before trying more expensive mineral facial sunscreens.
