Great tinted physical sunscreen
Size: 1.7 Ounce (Pack of 1)
This is my new favorite sunscreen. It goes on matte, but is still easy to put on/not pasty. The tint is enough to get rid of the ghost look but not so much that it looks like fake tanner. It's a bit greasier feeling than I'd like but it doesn't look greasy at all so I'll take it.

Stunning
Size: 1.7 Ounce (Pack of 1)
Good lord this is a beautiful mineral sunscreen. And at a reasonable price. It has a mouse-like consistency, is light and airy dries down to a satin-like finish after 15 or so minutes. It has a primer like feel to it which some might not like but this is perfect for those of us with combo/oily skin.
I’m fair/light skinned and the color is a perfect match. Gives me a light no-makeup makeup look. Works well under make-up as long as you let it set first.
One thing that's a con and has me on the fence about daily use is that because it's so thick and silicone like, you can't put the full 1/4 tsp on your face right away as it's just too much. For the 2 finger application I have to put it on in stages, and let each finger length dry down before adding the next, otherwise it's too much product to do all at once. Takes longer in the morning which isn't ideal but given everything else it has going for it it's still workable for me. I'll see over time if I want to repurchase.

Excellent sunscreen, my favorite
Size: 1.7 Ounce (Pack of 1), Size: 1.7 Ounce (Pack of 1)
In search for a perfect tinted sunscreen I have tried just about every brand of tinted mineral sunscreen that’s available here on Amazon, so you might recognize me from other reviews. I have a sensitive skin and can’t tolerate chemical sunscreen. I also have red and bumpy skin on my cheeks due to rosacea, so I need a tint to cover redness. I’m really glad I finally decided to give Sunbum tinted sunscreen a try because it quickly became one of my favorites. My other favorite is MD Solar Science BB cream in shade Light. These two are quite similar, both are very silicone like, due to a great amount of dimethicone. They feel like primers and because of that are very sticky and hard to wash off your fingers. But both look very natural and skin like. MD Solar Science (light shade) is slightly darker while Sunbum is pretty pale but not in an unhealthy way. My skin is a bit darker than Sunbum shade right now. Yet it covers my rosacea and evens out my skin tone just enough. It’s not drying but also not shiny, and because of that it doesn’t magnify wrinkles, which is a big plus: I’m tired of tinted sunscreens highlighting the wrinkles I have that are not even noticeable without them.
Sunbum is slightly lighter and provides a bit less coverage than MD Solar. It also doesn’t have much zinc, which was a point of criticism from popular bloggers. Because of that it might not be perfect for everyday wear. But if you want to have the most natural “no make up” look and you’re light skinned, this is a great choice on the days when you’re not expecting to be under too much sun. I use retinol on my forehead at night and I didn’t get sunburnt when using this sunscreen. So the only concern here would be the gradually accumulated damage from the long UV-A rays.
Another thing I like is that unlike MD Solar, Sunbum doesn’t contain vitamin C and therefore doesn’t irritate my sensitive skin. It’s also less expensive. I will keep repurchasing.
Note: in the unfiltered photo attached here, you can see the sunscreen after a 5 hour wear, that included eating, touching my face etc, so it’s a bit worn off and the redness on my cheeks is more visible. Even when freshly applied it didn’t cover redness completely because of being light coverage sunscreen.

Decent but not the best
Size: 1.7 Ounce (Pack of 1)
I like that this sunscreen is matte and tinted, but that’s about it. I have pretty oily skin and the mattifying effect only lasts for about 6-7 hours.
Unfortunately this product doesn’t absorb very well either. It tends to accumulate in any wrinkles and also tends to sit on top of any sort of facial hair or areas of dry skin.
A much better product, that absorbs very well and controls oil literally all day long, is Trader Joe’s mattifying facial sunscreen in the sea foam green tube. It isn’t tinted like Sun Bum but it beats it in every other category, especially in price.
