Real Sun Cover: The Reef-Safe Zinc That Stays on Your Face
25% non-nano zinc oxide, made in the USA, and worn every day by real surfers who are done with sunscreen that quits halfway through.
Quick Answer
Real Sun Cover is a reef-safe zinc face stick that actually stays on for a whole surf. It uses 25% non-nano zinc oxide, blocks 97% of UVA and UVB, and is made in the USA from four simple ingredients. Because it is a thick mineral zinc, it holds on the surface of your skin instead of disappearing, so it lasts while you paddle and push under waves, surfers say it stays out of their eyes, and you can see it is still there. The chemist who makes it, Eric, will tell you why zinc beats the chemical stuff and why the SPF number matters less than you think. It comes in Cocoa and Vanilla, and Hawaiian South Shore is the only place you can get it.
The Sunscreen on Your Face Has to Last the Whole Surf
Your face gets the most sun of anywhere when you surf, and it is the hardest spot to keep covered. You paddle out at first light, and two or three hours later the sunscreen you put on is supposed to still be working. Most of it is not. Thin, rub-in sunscreen soaks in, sweats off, and runs into your eyes the first time you push under a wave. By the time you get out, your face has been exposed for an hour and you never knew it.
That is the whole reason we carry Real Sun Cover. It is a thick mineral zinc built to stay on your face while you actually surf, not a lotion that quits halfway through. And the person who formulated it, a chemist named Eric who has spent about twenty years making sunscreen, has clear reasons for building it the way he did. A lot of this article is him.
What Is Real Sun Cover?
Real Sun Cover is an all-natural zinc sunscreen stick, made in the USA, with just four ingredients. The only active ingredient is 25% non-nano zinc oxide, and it blocks 97% of UVA and UVB. It is reef safe, baby safe, and non-greasy, and it is water resistant for 80 minutes. Hawaiian South Shore is the exclusive home of it.

Why Zinc, and Why That's the Only Active
Zinc oxide is the one sun filter Eric will build with, and he is blunt about why. It is a natural mineral, it does not soak into you, and it covers the widest range of the sun's rays of any active the FDA allows. It also does not fall apart in the sun.
The rest of the stick is short and boring on purpose: certified organic coconut oil, beeswax, and either cocoa powder or vanilla extract for scent and, in the Cocoa, a light tint. Eric points out the cocoa powder is not just color. It adds a mild antioxidant and the smell. Four ingredients, all organic except the zinc. That is the whole thing.
What's in Most Sunscreen, and Why Eric Won't Use It
The reason Eric only uses zinc is what the alternative actually does on your skin. Chemical sunscreens use petroleum-based filters, and Eric's point is that your skin lets small molecules like those pass through easily. He puts real numbers on it.
He goes further than absorption. His concern is that some of these filters may behave like hormones in the body, and that they do not biodegrade, which is also part of why they are hard on the reef. We are not going to tell you what to think about that. We are telling you what the chemist who studies it decided to do: leave all of it out and use one mineral. Zinc sits on top of your skin and reflects the sun rather than soaking in and reacting.
What "Non-Nano" Means, and Why It Matters
You will see "non-nano" on the label, and it is not a marketing word. A nanoparticle is anything smaller than 100 nanometers, small enough that there are real questions about it passing into places in your body it should not. Eric used a nano zinc when he started, twenty years ago, because it goes on clearer. He stopped.
He switched to a larger, high-purity zinc, made by a process that keeps the particles bigger, because there was not solid safety data on the tiny stuff and he would rather be safe than sorry. The part that matters for you: he found the larger zinc protects just as well. The nano version was mostly a clearer look, not better protection. So Real Sun Cover uses the non-nano zinc, and you trade a faint tint for peace of mind and the same coverage.
You Can See It, So You Know It's Working
Zinc is a pigment, which means the thing people call a downside is actually the feature. A chemical sunscreen disappears, and you have no idea whether it is still doing anything an hour later. With zinc, if you can see it on your face, it is there and it is working.
Eric gives a second reason zinc holds up where chemical sunscreen fades. In his telling, petroleum-based filters break down when the sun hits them, so they get weaker the longer you are out, which is a big reason the label tells you to reapply so often. He calls that almost a defective product. Zinc does not break down like that. It keeps working until you wash it off.
Does It Actually Stay On the Whole Time You're Out?
Yes, and it is the first thing regulars tell us when they come back for another stick. Because it is thick and built to stay put, it holds where a lighter sunscreen would be long gone. Christian, who works on boats and surfs, puts it plainly: this zinc stays on pretty much all day, where with other zincs he would feel like he had to reapply after an hour. Kiyara surfs through the middle of the day, noon to two, and the way she knows it really stays on is that she needs a makeup remover to get it off at the end.
None of that means it is set-and-forget. On a long day, reapply after about 80 minutes in the water, or after you towel off. The difference is that you are topping up a stick that is still mostly there, not starting over with something that melted off an hour ago.
It also stays on your face instead of smearing all over your gear. Steven, who has used the same stick for about two years, says the tint comes right off his wetsuit and does not get all over the place.
Will It Run Into My Eyes or Break Me Out?
Staying out of your eyes is the thing surfers mention most, right after staying on. Kiyara puts it on her cheeks and eyebrows and says it does not smear or get in her eyes. She has sensitive skin, the kind that reacts to a bad product, and gets no rash from it. Megan Abubo backs up the other worry people have: it does not break her out, and she gets no allergy from it. She has passed it to friends with fair skin who use it on their own kids.
That comes back to the formula. It is four ingredients, all organic except the zinc, with no fragrance chemicals and none of the petroleum-based filters that irritate a lot of people. Everyone's skin is different, but a number of our customers switched to Real Sun Cover precisely because other sunscreens stung their eyes or broke them out.
Why There's No SPF Number on It
Two reasons, and both are worth knowing. The first is simple: small all-natural sunscreen makers face strict rules around printing an SPF number, so Real Sun Cover states its protection as 97% of UVA and UVB instead. The second is that the SPF number is a shakier thing than most people realize.
There is also the math, which almost nobody explains. An SPF 30 blocks about 97% of UVB. An SPF 50 blocks about 98%. So a much bigger number on the front of the bottle is often one extra percent of protection, and with a chemical sunscreen that means a lot more of those absorbed chemicals for that one percent. Eric's point is not that SPF means nothing. It is that the number alone does not tell you what you are getting, so we would rather show you the ingredients and let you decide.
Is "Reef Safe" Actually Real?
It is real, but the label gets stretched, and Eric is direct about it. Hawaii banned oxybenzone and octinoxate. The way Eric sees it, a lot of brands just dropped those two chemicals and kept other petroleum-based filters that are close cousins, same benzene core, same behavior once they wash off you in the water.
Real Sun Cover uses 25% non-nano zinc oxide as its only active ingredient, with no oxybenzone or octinoxate. In parts of Hawaii, mineral-only sunscreen is not a preference anymore, it is the law. His rule of thumb for anyone standing in a store: if you cannot read and understand the ingredients, or you do not see zinc oxide, put it back.
Cocoa or Vanilla, Which One?
Same zinc, same protection, so it comes down to tint and scent. Cocoa is tinted with organic cocoa powder, so it blends in like a light foundation and carries a coconut-and-cocoa smell. Matt, who uses the Cocoa, says it goes on like a nice foundation and blends right in. Vanilla is made with vanilla extract, goes on lighter on the skin, and smells sweet. Pick Cocoa if you want a little color and warmth, Vanilla if you want it lighter and closer to clear.
How Long Does One Stick Last?
A long time, because a little covers your face and it does not melt away. Surfers who put it on every day tell us a single stick lasts them many months, and lighter users get close to a year out of one. Joey surfs every day and says his lasts about a year; Christian gets about six months out of his. You put on a little, rub it in, and go, so you are not burning through it day to day.
Frequently Asked Questions
Can I use Real Sun Cover on my kids?
Yes. It is baby safe, with a single mineral active and no fragrance chemicals, so parents use it on kids who will not sit still for sunscreen that stings. Several customers tell us they buy it mainly for their children because it does not run into their eyes.
Will the tint make me look strange?
The Cocoa blends in like a light foundation and reads as a light tan on most skin, not a white or orange cast. Customers describe it as looking like a natural tint rather than a mask. If you want the least color, choose the Vanilla, which goes on lighter. A light layer of zinc you can just see is normal and means it is working.
How is this different from other zinc sunscreens?
Two ways. First, it is a short, simple formula: 25% non-nano zinc oxide and three organic ingredients, with no petroleum-based chemicals and no fragrance. Second, it is thick and made to stay on, so surfers get a whole day out of it instead of reapplying every hour. Many thinner zincs either rub off fast or hide a low zinc percentage behind added chemicals.
How do I take it off?
Here's the trick most guys don't know: don't wet your face first. Take whatever soap or body wash you already use, rub it straight onto your dry face, then rinse. It's like getting grease off your hands — you don't wet your hands first and fight the grease, you work the soap into it dry and then wash it off. Same idea here. That's all it takes at the end of the day. It won't rinse off with just water, and that's the point — it's a sunscreen built to stay on in the surf instead of running off.
Does it work if you are not a surfer?
Yes. It was built for surfers, but it works for anyone outside for hours: paddlers, fishers, hikers, parents at the beach, and anyone with skin that reacts to regular sunscreen. The same things that make it good for a surfer, that it stays on and does not sting, make it good for a long day outdoors.
Does it feel greasy or heavy on your face?
No. It is non-greasy. A little covers your face, so you wear a thin layer instead of a thick, heavy mask, and it blends in as you rub it on rather than sitting on top like a cream.
