10 Best Reef-Safe Sunscreens for Hawaii and Beach Vacations
Sun protection comes first in mind when it comes to your Hawaii packing list. But hold your thought before throwing a bottle of your usual sunscreen from a grocery store.
Hawaii is the first state in the U.S. to ban the sale of sunscreens with toxic chemicals harming coral reefs, such as oxybenzone and octinoxate. The new law went into full effect on January 1, 2021.
Responsible travelers like yourself should comply with the law and help preserve marine life. But remember, what’s good for the environment is also good for you. Would you want to apply chemically-loaded sunscreens all over yourself? Not on me!
Before my Hawaii vacation, I dug deeper to understand various sunscreens, what to look for and what to avoid when purchasing sunscreen, and came up with a list of reef-safe sunscreens allowed in Hawaii (and beyond).
Once you learn all this, you will never look at sunscreen the same way you did before.

What is Reef-Safe Sunscreen?
To simply put it, a reef-safe sunscreen is a sunscreen free of harmful chemicals such as oxybenzone and octinoxate, which are known to damage and kill coral reefs.
I know it will get a tad bit technical. But let’s first understand how sunscreen works and what ingredients are used. I promise you will understand better how to protect you from sun damage while minimizing the pollution in the ecosystem.
But if you just want to know which sunscreen to buy for your Hawaii trip, jump to [Reef-safe Sunscreens for Hawaii].
Understanding Types of Sunscreen
There are three types of sunscreen categories by the mechanics of how it blocks the UV rays.
Mineral Sunscreen
Mineral sunscreen creates a physical barrier on your skin to block UV rays. This UV-reflective sunscreen is sometimes called physical sunscreen or sunblock. It usually contains Zinc or Titanium Dioxide. As it doesn’t get absorbed into the skin, it is gentle and suitable for sensitive or acne-prone skin.
However, some people may not like mineral sunscreen because the physical barrier (such as zinc oxide) can give it a chalky look. It can get “clumpy,” and you may feel it is challenging to apply mineral sunscreen on your skin. But new, improved products came out to minimize white casting and brighten skin tone.

Chemical Sunscreen
Chemical sunscreen uses chemicals to filter out UV rays. The most commonly used chemical ingredients include oxybenzone, octinoxate, avobenzone and octisalate. These chemicals first absorb and dissolve UV radiation before it reaches your skin. So you can say it’s a UV-absorbing sunscreen.
This type of sunscreen is typically cheaper and most commonly available. Chemicals make the sunscreen get absorbed quickly with an invisible finish. For that reason, many women prefer this lightweight formula to wear daily, especially under makeup.
Note that many chemical ingredients used in sunscreens are hormone disruptors. The skin absorbs these chemicals into your bloodstream, causing cancers in some people. It can also irritate your eyes and skin.
Hybrid Sunscreen
Hybrid sunscreen uses a blend of mineral and chemical ingredients. This type uses some chemicals to improve the look and feel of mineral sunscreen. Hybrid could be an excellent alternative for those who want to stay away from mineral sunscreen due to its chalky look or pasty texture.
Another benefit of hybrid is that combining UV-reflective and UV-absorbing actives can offer a higher SPF. (Note: A higher SPF does not mean stronger protection or better quality.)
Is the higher SPF the better?
Not necessarily. The Skin Cancer Foundation recommends applying for water-resistant, broad-spectrum protection with an SPF 30 or higher.
The SPF (Sun Protection Factor) number indicates how well it protects your skin from UV radiation. An SPF 30 provides 97% protection from UVB rays. (That means about 3% will hit your skin.) An SPF 50 offers 98% coverage, while SPF 100 shields 99%.
Here is the catch, though. The above is true in a well-controlled environment like a laboratory. In real life, you are sweating or going into the water. Therefore, don’t solely rely on high-SPF sunscreens alone for sun protection.
Regardless of the SPF value, you are advised to follow the best practice to minimize sunburn and UV damage, including wearing sunglasses and hats, finding shades, and wearing long sleeves.
Sunscreen Ingredients to Avoid
The “HEL list” by Heretics Environmental Laboratory is a list of chemicals known to pollute marine ecosystems and wildlife (e.g., corals, fish, mammals, turtles, etc.).
When you put sunscreens with these chemicals, they can get absorbed into the body or washed into the ecosystem from showering or swimming.
Therefore, it is best to avoid any ingredients in the HEL list:
oxybenzone
octinoxate
octocrylene
homosalate
4-methylbenzylidene camphor
para-aminobenzoic acid (PABA)
parabens
triclosan
any form of microplastics (e.g. exfoliating beads)
Particularly in Hawaii, the law bans the use of toxic sunscreens with oxybenzone and octinoxate. These two ingredients cause coral bleaching and can kill the reef.
Unfortunately, they are commonly used in most popular brands in the U.S., including Coppertone, Banana Boat, Hawaiian Tropic, and many more. (Disclaimer: These brands also produce Hawaii-approved versions nowadays, so do examine ingredients.)
Safe Sunscreen Ingredients Checklist
>> Mineral-formula sunblocks are the best choices.
Non-nano Zinc Oxide is safe for coral reefs. Opt for at least 7%. Using low content of non-nano titanium dioxide is also known to be safe.
>> Check the broad-spectrum formula covering both UVA and UVB.
>> Does it explicitly label as non-nano?
Non-nano refers to the size of ingredients. Larger particles do not get absorbed into the skin and are, therefore, very safe.
Many reef-friendly sunscreens with Zinc and Titanium Dioxide did not make this list because they used nanoparticles. If you do not see “non-nano” on the ingredients list or package, it most likely uses nanoparticles.
>> Do not be fooled by marketing words such as organic, safe, natural, etc.
Some products are advertised as “reef-friendly,” even though they contain chemicals like homosalate and octocrylene. Not using oxybenzone and octinoxate does not make a product completely reef safe. You will have to watch the ingredients out against the above HEL chemicals.

10 Best Reef-safe Sunscreens for Hawaii

#1. Little Hands Hawaii
Little Hands Hawaii Organic Reef Safe Mineral Sunscreen Butter is handmade in Hawaii with locally and organically sourced ingredients. The creamy sunscreen provides SPF 35+ and broad-spectrum UVA/UVB protection in plastic-free packaging. Many surfers in Hawaii love and use this water-resistant and marine-safe brand.
Its small package makes it easy to throw in a bag for reapplication. If you buy at a local farmer’s market, you can select many options, from various tinted shades to a recycled tin case to a stick.

It is a light lotion that is great for oily or acne-prone skin. Its gentle formula promises no eye stinging even with sweating. It goes smooth on clean, dry skin; I like to use it for my body. But when I reapplied on the beach, it was much harder to put evenly, probably due to water and sand.
I recommend buying Kokua Sun Care Sunscreen online. I checked the huge price difference at a local ABC mart in Hawaii.

Its formula is reef-safe, baby-safe, plant-based, cruelty-free, and water-resistant (up to 40 minutes). Did I say it smells lovely (minty), too?
I enjoyed putting this on my face and neck in Hawaii. A little goes a long way, and it glides without creating a white chalky look. But it would take up some effort to use fingers to spread all over an adult body.

Thanaka is a paste from ground bark containing antioxidants and rich vitamin E oil. This natural and organic paste has been used in Myanmar for sun protection and after-sun care. It is all-natural and safe for kids as well.
Natural coloring from cocoa adds a subtle tint. It blends better with skin instead of leaving the white cast. And this water-resistant sun creme applies so smoothly and easily. That said, it was my favorite sunscreen in Hawaii!
By the way, I was initially concerned about discoloring swimwear or clothing. Rest assured, that did not happen to me.
Manda Organic Sun Paste (SPF 50) is the same formula in paste suitable for outdoor adventures, such as surfing and hiking. Bonus point for its compact packaging.

ThinkSport Mineral Sunscreen is specially made for sports and outdoor use. This water-resistant sun cream (80-min in water) has SPF 50 and broad-spectrum UVA/UVB protection. You can use it on your face and body.
I mainly bought it for Big O who loves to play golf and outdoor sports. I tried it out in Hawaii for kayaking and was satisfied with how it applied smoothly and was water/sweat resistant. However, control how much you use. Using a little too much would make you look like a ghost.
Ingredient: Non-nano Zinc Oxide (20%), purified water, caprylic/capric triglyceride, polyglycery-4 isostearate, cetyl dimethicone, hexyl laurate, glycerin, hydrogenated methyl abietate (pine wood resin), magnesium sulfate (epsom salt), caprylhydroxamic acid, glyceryl

Unlike all other mineral sunscreens in this post, the main active ingredient of Stream2Sea is non-nano titanium dioxide. Generally speaking, high titanium dioxide content is not the best as this non-biodegrade mineral reacts in the warm sea to form hydrogen peroxide. However, no worries with Stream2Sea, which is Protect Land + Sea certified by the HEL.
Ingredients: Non-nano Titanium Dioxide, Green Tea Leaf, Tulsi Leaf, Wakame Seaweed, Olive Leaf, Aloe Leaf Juice, Coconut Oil, Stearic Acid, Acrylates Copolymer, Magnesium Aluminum Silicate, Sorbitan Palmitate, Tocopherol, Xanthan Gum, Alumina, Benzyl Alcohol, Salicylic Acid, Sorbic Acid.

What’s unique about this sunscreen is that it uses a specialized uncoated zinc oxide powder. As the manufacturer claims, these particles with a porous surface texture don’t reflect as much visible light as non-nano zinc oxide, hence less whitening on the skin. (I have not personally tested it, though.)
Ingredients: Uncoated Zinc Oxide (22.5%), Organic Sunflower Oil, Organic Beeswax, Sunflower Vitamin E. 98%
Why I Love It:
- Excellent water-resistant protection (up to 80 min.)

Application Tips
Maximize Protection While Minimizing White Casting
● Start with clean and moisturized skin. Zinc will apply more smoothly on well-hydrated skin. But water on the surface makes it difficult to spread sunscreen evenly. So wipe the water or sweat off before application.
● Be sure to apply all areas that will be exposed to sunlight, including behind the ears, neck, hands, feet, and scalp, 15 minutes before sun exposure.
● Start with a small dab to avoid looking like a ghost. Gradually rub in for even coverage before applying more.
● Make sure you apply enough. If spreading too thin, the sunscreen will not be effective. For a general reference, recommended amount to cover an entire adult body is about 1 oz (two tablespoons).
● Reapply at least every 2 hours. If you’re at the beach or pool, reapply after being in the water for 30-80 minutes or immediately after towel drying.
● Lastly, don’t forget to wear sunglasses and hats. Wearing long-sleeve rash guards also helps to protect your skin from sun damage.
