Are mineral chemical-free sunscreens safer?

I’ll tell you a secret: Chemical-free sunscreens don’t exist! WTH? Here’s the deal: everything is made of chemicals. Water? A chemical (H20). Olive oil? Made of chemicals. Your body? Hey, you’re made of chemicals, too! Truth bomb: if it’s made of matter, it’s a chemical. If chemical-free sunscreens existed, you’d get a big, fat bottle of… nothing! Heck, you wouldn’t even get the bottle. That’s made of chemicals, too.

So, why are people talking about chemical-free sunscreens?! And why am I writing a post on the best chemical-free sunscreens? Somehow, in recent years, chemical-free sunscreens has become synonymous with mineral sunscreens, a type of sunscreen that’s more natural (but still not chemical-free). And well, you can either correct people endlessly or you can use their teminology. In this article, I’ll share with you what chemical-free sunscreens are, how they work, and what the best picks for your face and body are:

What Are Chemical-Free Sunscreens?

Again, there are NO chemical-free sunscreens. But, for the sake of clarity, I’ll tell you what people mean with this expression and keep using it for the rest of the article. Chemical-free sunscreens are sunscreens that contain only natural UV filters. There are only two around: minerals Titanium Dioxide and Zinc Oxide. As they’re both minerals, better term than chemical-free sunscreens is mineral sunscreens. It’s actually accurate and doesn’t cause any fear-mongering. FYI, this doesn’t mean you’ll get a natural sunscreen. You can have zinc oxide in there, but the rest of the formula is still loaded with chemicals!

If we want to be picky (and I do), the correct term for sunscreens that contain natural UV filters is “inorganic”. Why? In science, anything that contains carbon is called “organic” and anything that doesn’t is “inorganic”. While other UV filters are organic ingredients, these two filters don’t contain a drop of carbon. They may have a natural origin, but they’re inorganic. Confused much?

I personally don’t think the term inorganic sunscreen will catch on anytime soon – especially when people associate natural with organic. I’d rather call them chemical-free sunscreen even if it’s incorrect. At last, this way we’re all clear on what we’re talking about.

How Do Chemical-Free Sunscreens Work?

You’ve probably heard that chemical-free sunscreens work by creating a shield on the skin that reflects UV rays away from it. I used to believe in that, too. I was wrong. Sort of. Titanium dioxide and zinc oxide, the two active ingredients in mineral sunscreens, can indeed reflect SOME UV rays away from your face. But, they do absorb the bulk of them, turning them into a less damaging form of energy (heat). Just like all other UV filters out there.

Are Chemical-Free Suncreens Safer And More Effective?

It depends. If you’re just looking for broad-spectrum protection, any sunscreen that protects both from UVA and UVB rays will give you that – regardless of the origin of their UV filters. Chemical UV filters don’t have half the health risks people claim they do (but that’s a topic for another post). But if you have sensitive skin that gets easily irritated, chemical-free sunscreens are a much better option for you. Why? Two reasons:

P.S. Needless to say, UV filters aren’t the only problematic ingredient for sensitive skin in sunscreens. Beware of fragrance, essential oils, and harsh preservatives, too. None of these are toxic ingredients that’ll kill you. They’re just irritating and are best avoided.

Do Chemical-Free Sunscreens Have Any Side Effects?

Titanium Dioxide and Zinc Oxide aren’t dangerous. They’re just… unpleasant. These minerals are so thick and white, they’re hard to spread, feel greasy on the skin and leave a ghostly white cast behind. There are ways to get around this. If the white cast bothers you, you can opt for a tinted mineral sunscreen. Or if you want a lightweight texture, look for a sunscreen that uses nanoparticles (these are controversial, so it’s hard to find a sunscreen with this technology).

Are nanoparticles safe? Studies suggest that nano-sized titanium dioxide and zinc oxide do not penetrate healthy skin. However, they should never be inhaled, which is why spray mineral sunscreens should be avoided.

Chemical-free sunscreens are getting better, but they’re not still as pleasant to use as “chemical sunscreens”. If texture is a dealbreaker, don’t feel forced to make them work for you. Unless you’re allergic to them, there’s no reason to avoid synthetic UV filters.

What Are The Best Chemical-Free Sunscreens?

Here are the best natural mineral sunscreens for your face and body. Keep in mind, not all sunscreen’s ingredients are natural. Because if that were the case, you’d be smearing grease on your face. These contain natural ingredients and synthetic ingredients that don’t get into your bloodstream and don’t cause harm. With that said, let’s look at the top-rated sunscreens for every skin type and need:

Drunk Ele​​​​phant Umbra Tinte Physical Daily Defense Broad Spectrum Sunscreen SPF 30 ($36.00): 

A tinted sunscreen with 20% zinc oxide that provides broad spectrum protection all on its own. And, because it’s tinted, you don’t have to worry as much about that annoying white cast mineral sunscreens are famous for. The texture is quite rich and leaves your skin looking glowy, so if you have oily skin, this probably won’t be your fave. But if your skin is normal or dry and you like your sunscreen to give you a bit of a glow, you’ll probably get along with it much better. It’s fragrance-free, too, and doesn’t contain anything that’ll give you a skin irritation  (of course, if your skin reacts to everything, patch test first, just in case). The only catch? There’s just one tint, and it won’t work for every skin tone.

EltaMD UV Pure BroadSpectrum SPF 47 ($43.00)

If you want a mineral sunscreen you can actually wear when you’re sweating your butt off, this is a good one to try. It uses 10% zinc oxide and 8% titanium dioxide and is water-resistant for up to 80 minutes, so it’s a much better choice for the beach, workouts and ridiculously hot summer days. The texture is a creamy lotion but doesn’t feel horribly heavy or greasy once it’s on. The downside? It goes on pretty white. It does become less obvious as you blend it in, but if you have a deeper skin tone, there’s still a chance it’ll leave a cast behind. Overall, a wonderful sunscreen that’s lightweight enough even for oily skin.

Available at: Dermstore and Walmart

Paula’s Choice Super-Light Daily Wrinkle Defense SPF 30 ($39.00)

My fave mineral sunscreen. Most zinc oxide sunscreens make you choose between looking like a ghost and looking like you’ve dunked your face in oil. This does neither. It has 13% zinc oxide, but the texture is super lightweight and dries down to a soft matte finish without leaving a greasy residue behind. There’s also a sheer tint that helps hide the white cast, although don’t expect it to replace your foundation – there’s barely any coverage here. If you have oily or combination skin, this is one of the better mineral options out there and the best decision you’ll make for your skin. It’s also loaded with antioxidants to keep premature aging at bay, not just a sunburn.  Dry skin? You’ll probably want a good moisturiser underneath because this isn’t particularly hydrating.

Available at: Cult Beauty, Dermstore and Paula’s Choice

Mad Hippie Ultra-Sheer Body SPF 40+ ($18.99)

A mineral body sunscreen with 20.5% non-nano zinc oxide and 80 minutes of water resistance, so it’s a great one for beach days, swimming, or just sweating your way through summer. Despite the name, it isn’t quite as “ultra-sheer” as you may expect. The creamy formula can feel a little thick and tacky at first, and you need to take your time rubbing it in. Once you do, though, the white cast is pretty minimal on lighter skin tones (although it may still show up on deeper skin). I also like that it doesn’t just protect your skin from the sun. You’re getting moisturising squalane, sunflower oil  and hyaluronic acid, plus antioxidants like sea buckthorn and vitamin E to hydrate skin and fight wrinkles. If you hate the dry, chalky feel of old-school mineral body sunscreens, this is definitely a step up – just don’t expect it to feel completely weightless. FYI, this is the most natural product on this list.

First Aid Beauty Ultra Light Liquid Mineral Sunscreen with Zinc Oxide SPF 30 ($38.00)

If thick, pasty mineral sunscreens make you want to skip SPF altogether, this is much more up your street. It has a really thin, almost runny texture that spreads easily and feels surprisingly lightweight for a zinc oxide sunscreen. There’s a sheer tint to help get rid of that annoying white cast, although I wouldn’t call it universal. It seems to work best on light to medium skin tones and may still look a little ashy on deeper skin. The finish is satin rather than super matte or greasy, with a subtle blurring effect that makes it a lovely base for makeup. Plus, it’s fragrance-free and non-comedogenic, so it’s a good option if your skin is sensitive or prone to breakouts. Just remember to give the bottle a good shake before you use it – that lightweight liquid formula needs it.

Are Zinc Oxide And Titanium Dioxide Safe For Coral Reefs?

Not necessarily. Just because a sunscreen is mineral, doesn’t automatically make it “reef-safe.” Research has found that zinc oxide nanoparticles can harm coral and other marine life. One study found that uncoated nano zinc oxide caused severe coral bleaching, while other research has linked it to oxidative stress and toxicity in marine organisms.

Titanium dioxide seems to be the lesser of two evils. In the same study, it was much less damaging to coral than zinc oxide. But that doesn’t mean it gets a completely clean bill of health. Other studies have found that high concentrations of nano titanium dioxide can affect coral survival, too. 

The bottom line? I wouldn’t assume a sunscreen is better for the ocean just because it uses mineral filters. “Mineral” and “reef-safe” aren’t the same thing.

The Bottom Line

Technically, chemical-free sunscreens don’t exist. But people use the term to talk about sunscreens that contain mineral filters. They’re a gentler option for sensitive skin, but there’s no other reason to choose them over synthetic UV filters. When picking a sunscreen, focus on what works for your skin. Whether that’s a mineral sunscreen or a chemical one, the best sunscreen is the one you’ll actually wear every day.
