I put my heart and soul into finding the best natural mineral sunscreen over the last 10 years. My family of 6 has personally tested over 100 reef-safe sunscreen options, putting two on our bodies every time we are in the sun.
Our a/b tests have been stringent, and we really know what mineral sunscreens are effective, rub in well, and last a long time.
Of all those well over 100 choices, we only have about a dozen that we love and this brand is one of them.
If you’re looking for one of the best natural sunscreens, you’re in the right place!
As you’ll read in the full review below, this zinc oxide sunscreen covers all the bases and keeps your family safe from sunburn. It uses pristine ingredients to the highest standard, goes on smooth, and actually lasts.
If you’d like to see how it stacks up against other natural mineral sunscreen brands that use reef-safe zinc oxide, then head over to my ultimate guide to natural mineral sunscreens for the complete list of safe sunscreen reviews.

My review: I’ve seen Stream2Sea on reef-safe lists and in scuba shops many times, so I was pleased to finally get a chance to test it out. Imagine my dismay when I flipped the tube over to see titanium dioxide only as the single ingredient. Titanium dioxide is less powerful as a broad-spectrum ingredient than zinc oxide, and it’s actually quite rare to see titanium dioxide only without zinc. One potential benefit is that if someone has an allergy or reaction to zinc oxide, this product would come with my highest recommendation. As it is, because there’s no zinc it can’t go in my top-recommended tier right off the bat. But let’s see how it performs.
I hit another disappointment immediately when we discovered that the white body lotion doesn’t really rub in any better than a zinc oxide cream. There’s a definite pasty, white cast all up and down the arm. The texture is nice and pleasant and not sticky. But visually, Stream2Sea leaves a lot to be desired.
Luckily, the tinted version fixes this right up. I felt the tint looked great on both of our complexions. Mine is more olive and my husband’s much more pink and Irish, French-Canadian white. For faces I would highly recommend the tint. And it looked okay on the arms as well.
We tested the original sport SPF 30 and the tinted in SPF 20. Both versions are available in 20 and 30.
While in Sedona, we put the Earth Mama stick on the right hand side of our faces and the Stream2Sea tinted on the left. We had no differences I could ascertain in tan and no burning. It’s kind of interesting that there were no differences though, because we had a good bit of sun and Stream2Sea is only 20 SPF, 6.6% titanium dioxide only. And Earth Mama is 22% zinc, SPF 40. It’s very curious that they showed no difference. I’m really surprised that such a low percentage titanium dioxide performed so well. Stream2Sea has definitely proven itself, both SPF 20 and 30. It performed well; it protects from burns.
We were putting it on out on the trail, not in the mirror. And when I got home, I did have a line of burn that I don’t believe I had the day before on the very top of my forehead, like right below the hairline, like less than a centimeter the whole way across. I think probably either I didn’t rub up that high, not wanting to hit my hair, or my hat maybe rubbed it off somehow. More likely the former than the latter, which would show that both of those sunscreens work really well.
