It has a white film

It’s a good sunscreen but has an obvious white film even when you fully rub it in.

Not your mother's sunscreen. .

I take ingredients very seriously. Especially for things I put on or in my body everyday. I've started getting this sunscreen auto shipped every two months, as a way to hold myself accountable with daily use regardless of my activity, and to avoid needing to buy something on impulse.I've done plenty of research and ended up here with Stream2Sea. (Past products ingredients changed and have pollutants and endocrine disruptors, no thanks)I use the Yuka app to compare and dig deeper into ingredients of cosmetics and food as a jumping off point, it's been invaluable.This sunscreen goes a LONG way. It is said you need about a shot glass worth for your entire body, unlike run-of-the-mill sunscreens that you need to lather on to get a good layer of coverage. That's why I don't mind paying more for less product that is quality & safe. For me and for the ocean.I have fair skin and can burn easily but I'm more concerned these days with sun exposure in general because skin cancer is so common and living in Florida feels much different than living in Michigan, ha!So, to sum up, start with less and blend, blend. The white cast you might end up with will fade and with regular use you can mostly avoid.For my face I use Fuka Eri. It's a Zinc oxide and titanium dioxide non nano vegan formula that's reefsafe and cruelty free.I keep it just outside on the back porch so it stays soft for easy application and the tinted version I cut with a tiny bit of coconut oil so it goes on like moisturizer and makes the product go farther avoiding unnecessary waste. 🙂Hope this review helps. ☀️🧴

Stream2Sea for me

When I started diving the boats would not let anybody use any other sunblock on the reefs. Stream2Sea is biodegradable. Other brands are not. Example; Sunbum is made by SC Johnson which is a chemical company known for making pest control products like RAID or cleaning products like DRANO.

You guys, it works!

So I get sunburnt SUPER fast! But when me and my family went to the zoo the other day, I put this stuff on and I didn’t even turn red! We were there for hours! Super helpful y’all get this awesome product. My mom didn’t use it and she was super red, y’all must try this.

Scuba, apply, doze in sun, repeat.

Between dives on live aboard in Turks and Caicos, I warmed up in the sun. Stream2Sea was quickly approved as a sunscreen for use that didn’t harm the coral I was enjoying during my dives.The slight white it left on our skin became a badge of honor!

Great travel size

This is the perfect size to take with you.

Excellent Sunscreen

This sunscreens will last pretty much all day! It is the mineral sunscreen so it will make you look more white than other sunscreens, but it is better for you skin and body. Plus it does not wash off in the water very easily. Great for the beach

Leaves a residue

I’m glad it’s reef safe and good for the ocean however I used it once and haven’t used it since because it leaves an awful residue and you can’t rub it away

Offers good sun protection

I bought this for a Caribbean vacation and wanted a brand that was reef safe. It offered good sun protection, but like most reef safe sun screens, it took a while to rub in and left my skin with a white tint.

Okay

Im so happy for the brand and how much ocean conservation they do. However, this does not easily spread leaving you looking like a ghost

Non-Toxic

Yes this is pricey but it’s non-toxic. this item was suggested by the Yuka app!

It works but....

Bought this for a trip to Mexico where certain sunscreens are banned. I thought it was rather expensive for a small tube.It did work though. I spent several days in the sun including swimming and in parks and did not burn.As others have noted though it doesn't rub in very well. If you weren't white to begin with you will be after applying this stuff.I will say it is much more waterproof than typical sunscreens. After being in water for more than 2 hrs I could still see the areas of my skin where it hadn't been fully rubbed in still had white sunscreen streaks on them.It also doesn't smell bad. So you won't have that tell tale sunscreen smell. I do like that about this sunscreen.Overall its not bad. It does work. I kind of prefer sunscreens that actually rub in though.

The white film never goes away

This product left a white cast that never wore off until I washed it off. If you buy it, this may happen to you. However, when the company realized I had a problem with their product they had truly excellent customer support, which is unusual at a time when most sellers rely on computers to handle all their problems with customers. This company gets 5 stars for customer service.

Approved by EWG- Nurse Approved

Approved by EWG environmental working group. if you're not familiar with this group please check them out! This product is Nurse Approved! EWG are Powerhouse in alerting the government and consumers of dangerous chemicals. The European Union has banned many chemicals that are still used in the United States that are dangerous for human consumption. They also have an app where you could look up any product and it tells you on a scale the chemical exposures you may experience. Who wants to expose themselves and their family more dangerous chemicals? Remember the zinc sunscreen in the 80s and the life guards with the white noses? This sunscreen goes on thick and because of the zinc content does not rub in very easily and stays very white on the skin. I just use a few drops of water to rub it into the skin a little better so I'm not Ghostly white. I've used it four times this summer so far with hours of sun exposure paddleboarding and have not experienced any sun burns. Tanning nicely. It's expensive for the size and the amount of suntan lotion that you get. Knowing that I'm not exposing myself to additional harmful chemicals is worth it for me!

White Residue

While this may be good sunscreen, even using a small amount will leave a white residue that will not rub in.

Works well but stays very white

Works well in water for hours, but this stuff is impossible to rub all the way in. Even after scrubbing in the shower my legs still had white on them.

Works well, looks ugly

This is a great sunscreen in that it actually protects you and is truly waterproof. I wore it kayaking in Mexico where the sun is strong. I never burned. The downside is that it leaves you white and pasty looking while wearing it. But if you don’t mind that, you can feel confident in it’s protection.

Thick and chalky

Unfortunately, this product does leave your skin white and chalky. I loved that it was a little lower spf @ 20, but I found that I didn’t want to use it at the pool because I looked like a ghost! I moved on to Babo and Absolutely Natural, both providing the same natural, non-toxic protection without the white residue.

really loved this sunscreen! I was searching for something that didn’t have too harmful of ingredients and this was the one I found! I went to the beach in California and used it and it was perfect!

Works, but you turn into a ghost

It works well, definitely waterproof… but is so so white and does not absorb. This is on very pale skin to start with, can’t think what it would be like on darker skin!

Works but doesn't rub in and leaves you looking like a ghost

Kept me from burning in Punta Cana but it has an odd smell but the big issue was that it doesn't rub in and leaves you with a white look to your skin.

Reef safe but!!

Not easy to spread, very thick and kinda turns into a purple color (light) ok to use if you need the reef safe stuff but I would stick with the spray on for coverage and ease of use.

works fine, smells awful

Like most mineral sunscreens I've ever used, this one was a little difficult to spread, but we got the job done. It works fine. It smells terrible. It's not a strong smell, but it is unpleasant.
