  1. John R.

    It makes me feel good that I’m protected with a biodegradable sunscreen that is safe for my skin, especially my child, and is also non-toxic to the aquatic animals we love.

  2. Autumn B.

    This is the best sunscreen ever! I have to take the time to apply it properly, but once I do, it will hold all day and not run into my eyes or rinse off when I’m playing in the water. I love that it is safe for me and the environment!

  3. Kat H. (verified owner)

    I spent ten days in the summer Bahama sun with 3oz of this sunscreen and still came back with half a tube! A little of this product goes a long way. I also came home without any crazy dark spots on my face like I usually do with other sunscreens! I felt protected every minute, never got burnt, and definitely felt good about diving, snorkeling, and swimming knowing that I wasn’t any toxic chemicals to the ocean.

  4. tigger86334 (verified owner)

    I love this.. Being in Arizona the sun is intense and being fair skinned I burn easily.. This product is great. No burn. Plus the added fact that I am a diver and I know that I am protecting the underwater life that I enjoy so much. Thumbs up for your product

  5. Rosemary C.

    I am a scuba diver and love that I can protect the coral reef while diving!

  6. Krys

    This is the best sunscreen ever! You have to use like half as much as normal, which makes it very affordable. It doesn’t burn my eyes and I didn’t get the slightest bit burned. Great product!

  7. Viktoria

    My partner and I are both scuba divers and we care about the reefs and of course our own health and skin just as much. Usually I try to wear a lycra shirt to protect myself from the sun, but sometimes I need some more protection – especially on hands and face.
    We both like how long the bottle lasts and while we appear a bit white when wearing it, at least we know where we applied it already. I prefer to have a bit of a white touch instead of being burnt!

  8. Laura (verified owner)

    I usually hate using sunscreen because it’s bad for the environment and also it burns my face. This cream is amazing. On a recent research trip in the Maldives, my entire team used this sunscreen and no one got burned! We were in the sun for long hours and it held up against diving/snorkeling and sweat. Keep in mind this product goes a long way and you need to mindfully rub it in for an effective layer. Embrace the white face and you will love the protection this sunscreen offers!

  9. Capt. J.

    I’m a tennis player from central Texas. I play in the sun almost every day. The Sport SPF-30 is great: no runs, no drips, no grease, & no burns.

  10. Diana (verified owner)

    Love this product – very timely shipping, effective and lasts a long time! highly recommend.

  11. Hannah L.

    I love this sunblock! Not only do you feel good because you’re keeping the ocean safe, but it feels light. It’s not greasy and it works so well!

  12. raymen (verified owner)

    Purchased the SPF 30 body use sunscreen specifically for my “tuna white” legs while working on and around my sailboat. This product goes on easily and has worked very well, so well the SPF 20 face and body sunscreen was just ordered and will be used by me personally and recommended to the folks joining me on SV: Wind Dancer.

  13. roblou22 (verified owner)

    Video was very informative and the technique worked very well. Our big bottle came with a convenient dispenser and we will be doing our own decanting in the future. I used the packing materials to clean some fish that I was preparing better than newspaper. Will definitely .recommend

  14. Taylor U. (verified owner)

    I LOVE Stream2sea! While using, I have never been sun burned and my skin never feels greasy. It feels good to use a product that isn’t toxic to me or the ocean’s ecosystems. I will add that this sunscreen does leave a while tint to your skin, but if that bothers you then go for the tinted version. That one is great too!

  15. Ladyracer23 (verified owner)

    Most off the shelf sunscreens make my skin itch and cause allergic reactions. This sunscreen is not only safe for reefs and ocean life, it’s safe for those of us with sensitive skin. It’s a total win-win.

  16. Vickie M. (verified owner)

    This sunscreen works great (especially on the head for those with thin hair). It does not feel overly greasy or heavy. I love being outside and protecting both my skin and the environment are important. It feels so good to know that I am using a product that supports both of these goals.

  17. Kirsten J. (verified owner)

    I love my Stream2Sea sunscreen!! We have been using mineral sunscreen for several years and truly prefer it. There is such a difference when you put it on your skin and you don’t feel slimy! On the other hand, it forces you to conserve because if you use to much, you end up looking like a ghost, or slightly purple!

    We used just a small amount and rubbed it in really well. Even the bottle is ecofriendly – made from sugar cane instead of plastic! We were big fans of the company – really supporting what they stand for and glad to help a company that is trying to help protect the environment.

    After a couple hours of beach play – we had no burned faces and only exhausted children to pack into the car. I am a big fan of the suncreen and love what the company stands for!

  18. Autumn B.

    Thank you so much, Kirsten!

    This trip I tried out the Stream2Sea sunscreen. We carried a 3 oz bottle and certainly found that a little goes a long way. It’s a mineral sunscreen so you just use a dab and rub it in. The videos on their website clearly show how to apply it.

    Hiking the Little Elk trail on a sunny day was beautiful. As someone who grew too tall for their hair, I am always concerned about the bald head getting too much sun. I used the white sunscreen (not the tinted) and it went on with just a bit of white sheen. It does absorb in with more rubbing and became less noticeable. Using just enough was key. I liked that it didn’t run down into my eyes as I hiked the almost 10 miles. The sun was hot but I didn’t get burnt. I did use my hat for part of the way for a bit of shade but mostly my head was in the sun.

    I did have trouble cleaning off the sunscreen. Since water is a bit unsafe at camp now, I tried to conserve by using a wet wipe. My skin was left with a sheen of sunscreen that lasted for a little while. This shouldn’t be an issue when enough water is available to clean up.

    The Stream2Sea products don’t harm the environment which is a big plus. I receive emails from the company that consistently talk about their commitment to not harming the planet. This adds to the positive feeling I get using their products. Thanks, Stream2Sea, for protecting my skin as much as the environment.

  20. kpirozzi (verified owner)

    I love this sunscreen. I found it on the PADI site as their suggestion of the only proven reef friendly sunscreen. The suggestion of using moisturizer beforehand helped as otherwise, I have to use a lot to get it to spread. I discovered that it’s the only sunscreen I’ve ever used that doesn’t cause breakouts, including other reef friendly sunblocks! I also love the stream2sea moisturizer.

  21. saundramichelle@hotmail.com (verified owner)

    My son burns easily. After refusing to use this sunscreen on the first day of our vacation, his shoulders and nose burned despite 50 SPF of the chemical sunscreens.
    Afterward, he started using this sunscreen and enjoyed hours of pool & beach time!
    The instructional video for how to apply was VERY helpful!

  22. Jonny (verified owner)

    The second I heard this was reef safe I made the purchase and I have to say its definitely better than that watery stuff you get at any big box store. This stuff stays on you for a long time too. 11/10

  23. Jonny (verified owner)

    Once I heard this was reef safe I jumped on it immediately. It’s way better than that watery stuff you get at any major retailers and it lasts longer too. 11/10

  24. Brandy (verified owner)

    This is my favorite sunblock now and I will recommend to everyone I know! It works great and is safe for the fish and reefs. If you don’t know how to apply this make sure you watch the video first.

  25. April U. (verified owner)

    I love this product. Every time I use it I am grateful to know I am not harming sea life. I use it daily especially when heading out to the garden. When it dries it feels very comfortable, like nothing on. It is so easy to spread and lightweight on the skin.

  26. Brittany D.

    I have loved the Stream2Sea products. I think they are doing an amazing job creating products that are eco friendly and a step further, that the packaging also is. The sunscreen works really well and I have never been sunburned using it. It works well for people that have sensitive skin. My daughter cannot use many brands of sunscreens because the ingredients either sting or itch or are uncomfortable on her. Love Stream2Sea because it protects us and protects the environment! The only reason I give it 4 stars instead of 5, is because it does stay on white after applied. It’s easy to know where we are covered and protected, but it is obvious and shows. Would love to see a stick sunscreen for even easier application!

  27. Jenni

    The only sunscreen I’ll buy! Safe for me, safe for the ocean, and it works to protect my pale skin.

  28. Harith W. (verified owner)

    crafted by an authentic scientist who is dedicated to preserving our marine and coral. love Sea2Stream products. Even President Clinton waved and showed the 400 plus audience. Autumn at her own expense visited USVI to support and testify the ban of toxic sunscreen. she is a leader and pioneer. and supporting such evangelists not only feel good but also helps the environment.

  29. April U. (verified owner)

    I bought a huge bottle because I use this daily. I love that it washes off easily with soap and water which many mineral sunscreens do not. I can use a very thin veil which lightens my skin tone slightly, but in a glowing way like a diffuser rather than chalky. I am especially happy that it is safe for sea life.

  30. Joe W.

    Good stuff. I hate sunscreen, but yours is by far the best one.

  31. Thalia D.

    My all time favorite sunscreen! Feels good and is better for the environment too!

  32. vauglestotle (verified owner)

    Favorite sunscreen! Does get everywhere for me though after an application, but at least I’m protected. Goes on almost like a body butter but is more thick, which is far better than other sunscreens I’ve used. Feel good about being able to go in the water and not harm the wildlife. No burn whatsoever except for where I had washed off my hands.

  33. robert d. (verified owner)

    Haven’t actually used it yet, but with all the great reviews and the stated qualities of this sunblock I can’t wait to use it on my vacation. I am going to go ahead and say that I can’t wait to use it and hope my review stands.

  34. JW (verified owner)

    I love this product. I use it all the time to keep sun damage off of my skin and the oceans safe. I am a scuba diver and it breaks my heart to see the reefs dying knowing it is due to some factors we as individuals can’t control but I know that me using this product helps keep the reefs and the creatures that depend on them alive longer.

  35. Kimberly

    Received as a gift and pleasantly surprised. Kept my skin safe, stayed on well and very happy with it! Love that it’s safe for the reefs too.

  36. Erica

    Great product.

  37. Erica

    Best sunscreen

  38. Madison

    I love the smell and feel ove this sunscreen, especially compared to most reef-safe brands. It doesn’t tend to break me out like others I have tried (though I do not have sensitive skin). My one minor gripe is that it definitely does leave a white sheen but, I can live with it.

  39. Laura C.

    I’ve used these before and product does exactly what they claim. And they make you feel good for keeping our oceans and reefs safe.

  40. Natalie C. (verified owner)

    I love this sunscreen for a few reasons. Mostly because it’s reef safe but also because it glides on so nicely and makes covering my skin very easy. The ingredients list are all recognizable. I was sent a small tinted version of this product and LOVE IT! I use it on my face every morning now and will order the larger size when I run out. I have two grandchildren and ordered some sunscreen for them because it makes me feel good knowing it’s safe for their young skin when applied.

  41. Lenah W.

    My favorite! Goes on the smoothest!

  42. Pam D.

    So glad to find a great sunscreen that will protect myself yet not harm our oceans . I haven’t used it yet but this was the recommended brand for snorkeling in Cozumel.

  43. Pamela D.

    So happy to have found a product that protects myself and my family and the confidence that it does not harm reefs. Having had melanoma 13 years ago , I can not take any chances .

  44. Tom T.

    Finally a coral saving product that makes sense and works. Thank you!

  45. Tom T.

    It works. It saves our corals. Thank you!

  46. Jackie H.

    As a long-time user of Stream2Sea sunscreens, I didn’t think they could get any better.

    I was wrong.

    I love the new Every Day Mineral Sunscreen — sheer, as advertised and very effective at 45 SPF.

    My family and I took a 1.5-hour boat trip in order to wander for 6 hours through the maritime forest at the Cumberland Island National Seashore. What made this fantastic adventure even better was when my niece said, upon our return, “I can’t even tell you’ve been in the sun all day.”

    It’s a fantastic product and I will purchase the tinted version next to use as makeup foundation for my face.

    Thank you for a great sunscreen and keep up the good work!

  47. YT: S.

    We are avid snorkelers and have tried many reef friendly sunscreens and nothing beats Stream2Sea. Period. Won’t even buy anything else to try now because it’s not worth it. This works. Tried and true.

  48. Ellen (verified owner)

    My go to sunscreen for all uses. I initially bought it for snorkeling, but I like the lack of nasty ingredients so I use it exclusively now.

  49. Ana M. (verified owner)

    I used it over the Memorial Day weekend & it works. I don’t normally wear mineral sunscreen because it’s so white. I was looking for something that went on clear. I love this one because you can’t even tell I have it on. And I love how it’s safe for everything in the water. Definitely will be buying again in the future.

  50. J L. (verified owner)

    It’s nice to have a sunscreen that doesn’t glomp or feel disgusting as someone who dislikes lotions and such

  51. Lulu

    Love the ingredients and it works great. Remember to apply a little at first and work it in. The first time I used it I put too much and the white cast was strong but surprisingly it faded after a few minutes.

  52. stephaniekvcs

    I picked up a sample size of this at Natural Grocers and loved it—I didn’t find that it left an excessive white cast either! I am used to purchasing mineral sunscreens, you just have to rub it in! Ordering the full size online!

  53. Andrea A. (verified owner)

    Love this company and all of their products. I’ve found my go-to for great lotions and sunscreens that I can feel confident are sustainable all around!

  54. Jeannine J. (verified owner)

    Excellent product. Use every day in the hot Florida sun. Holds up well in the water and while working outside. Highly recommend.

  55. Patricia (verified owner)

    I bought this sunblock to help with marathon training last year. I was so happy to know it would be safe for the ocean and water systems since we would be in Hawaii. Not only was it good at protecting me from sunburns but also not stinging my eyes. Most others always do after that much sweating. Just bought more for another beach vacation. Complete fan!

  56. Shelia (verified owner)

    I love that these products are reef safe!
    The sunscreens and hand sanitizer work perfectly and I’m looking forward to more.

  57. Chanin W. (verified owner)

    I am a diver, so Reef-Safe is really important to me…and so is protecting my skin. Really like this sunscreen. Just re-ordered a bunch. 🙂

Safe For You and Safe For Our Waters

What does tested & proven safe means for our bodies, waters and coral reefs?

Just because the front of the bottle might say it is reef safe does not mean that it is. That is because these terms are not yet regulated. You still need to look at the back, starting with the active ingredients listing. We have also discovered that just because a product is safe for people does not mean it’s safe in an aquatic ecosystem. Modern science has given us many lab tests to determine the safety of cosmetics, but there are currently few scientific lab tests to see if products are harmful to fish, coral and other aquatic life. We put Stream2Sea products through numerous studies to prove our safety, and believe that our products are the safest on the market for all your water, reef and outdoor activities.

Biodegradability Tests

It is important to know that just because a product is biodegradable for example, a biodegradable sunscreen, does not mean that it is non-toxic. To be considered ‘readily biodegradable’, the product must break down into its natural state from 60-80% in 28 days. Stream2Sea products are readily biodegradable in fresh and salt water.

Reef and Marine Life Safety Tests

Swimming behavior with Stream2Sea biodegradable mineral sunscreen is relatively unaffected, whereas the competitor sunscreen most definitely altered the fish’s swimming behavior.
