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.

Great product. No white cast

This is a great everyday face sunscreen. It doesn’t leave a white cast. It’s not greasy. It leaves a nice dewy finish. Strongly recommend.

Great sheer mineral sunscreen!
Size: 1.7 Fl Oz (Pack of 1), Size: 1.7 Fl Oz (Pack of 1)
I’ve never been a mineral sunscreen fan but I really love this one. I needed a mineral sunscreen for days where I knew I was going to be sweating or swimming because the chemical stuff would run into my eyes and burn so bad. This one doesn’t burn my eyes at all.
It doesn’t leave a white cast but it is a little oily and leaves me quite shiny for about 10-15 mins until it fully dries. I don’t really mind because it works well.
I would definitely recommend 👌

It's okay. Better for dry skin.
Size: 1.7 Fl Oz (Pack of 1)
It's a nice product but still too greasy for my poor skin. It's pretty moisturizing. It isnt thick, but my skin gets greasy quickly with it. (I prefer Australian Gold tinted (the big tube meant for the body, not face).
