Let’s set the scene. You’re at the beach. You’ve packed the snacks, the SPF 50+, the rashies, and three changes of clothes for kids who somehow end up naked in the sand anyway. You’ve remembered everything—yet you’re still Googling “why do I always burn under my sunnies?”
Sound familiar?
In a world where some say sunscreen is saving us and others claim it’s silently poisoning us, it’s hard to know what to actually believe. Add a dash of conspiracy theories, throw in a viral TikTok about seed oils, and suddenly you’re spiralling while smearing a white cast across your toddler’s cheeks.
Let’s breathe. And break it all down.
🧴 First up: What Is Sunscreen, Really?
Sunscreen is a topical product that helps protect your skin from UV radiation. It generally falls into two categories:
☀️ Chemical Sunscreen
These use active ingredients like:
- Oxybenzone
- Avobenzone
- Octinoxate
- Homosalate
They absorb UV rays, convert them into heat, and release them from the skin. Think of them as UV bouncers—they don’t block the door, but they handle the riff-raff.
Pros:
- Rubs in easily
- No white cast
- Often water-resistant
Cons:
- Some ingredients (like oxybenzone) have been linked to hormone disruption in lab tests (see Krause et al., 2012, International Journal of Andrology)
- Can cause skin irritation or breakouts
- Not reef-safe
⛱ Mineral (aka Physical) Sunscreen
These use:
- Zinc oxide
- Titanium dioxide
Mineral sunscreens sit on top of the skin and reflect UV rays away—like a tiny disco ball for your face.
Pros:
- Less irritating for sensitive skin
- Starts working immediately
- Often reef-safe
- Low-tox mum approved
Cons:
- Can leave a white cast (unless tinted or nanoparticle-based)
- Might feel heavier on the skin
- Not always sweat or water resistant
👩⚕️ Wait—Is Sunscreen Toxic?
Let’s be clear: sunscreen is not toxic. The vast majority of mainstream formulations are rigorously tested for safety. That said, certain ingredients like oxybenzone and octinoxate have raised red flags in recent years due to:
- Potential hormone-disrupting effects in animal studies
- High absorption levels in blood and breast milk (see Matta et al., 2020, JAMA)
- Environmental impact (i.e. coral reef bleaching)
Does that mean you should panic? No. But it’s totally fair to prefer low-tox, mineral-based options—especially for young kids or if you’re trying to reduce your chemical load overall.
The Conspiracy Theories: Let’s Talk About Them
🤯 “What if sunscreen is what’s actually causing skin cancer?”
No. Just no. Sunscreen is one of the most well-studied skincare categories in the world. While not all formulas are created equal, there is zero credible evidence that properly formulated sunscreen causes skin cancer.
What is backed by science?
- Sunburn = DNA damage = increased skin cancer risk (see Skin Cancer Foundation, 2023)
- Sunscreen = protective barrier = reduced risk when applied correctly
End scene.
😎 “But sunglasses are tricking our body and making us burn faster!”
This theory gets a lot of play online, so let’s unpack it.
The claim: Wearing sunglasses stops your eyes from signalling your skin to produce melanin (aka natural protection), leaving you more prone to sunburn.
Truth? There’s no solid science to support this. While your body does respond to light through the eyes (hello, circadian rhythm), there’s no clinical evidence that sunnies stop your skin from defending itself. What they do prevent? UV damage to your eyes. So please, keep the shades on.
🥬 “Is it my DIET that’s making me burn?”
Okay, this one’s actually… kind of interesting.
Emerging studies suggest that certain nutrients can increase your skin’s natural resilience to UV rays. Think of them as SPF from the inside out (but definitely not a replacement for sunscreen).
Top internal SPF boosters:
- Lycopene (found in tomatoes)
- Beta-carotene (carrots, sweet potato)
- Astaxanthin (found in salmon and algae)
- Omega-3s (anti-inflammatory, supports skin repair)
- Antioxidants like vitamin C, E, and polyphenols
And yes—seed oils, which are high in omega-6 fatty acids, may throw off your skin’s natural inflammation response. But we need more research. (If you’ve seen a peer-reviewed study on this, send it our way)
TL;DR: clean up the pantry, eat more rainbow food, but still wear sunscreen.
🧴 Could Your Skincare Be Making It Worse?
Actually… yes.
Common skincare saboteurs:
- Acids (like AHA/BHA) – They exfoliate and thin the top layer of skin, making you more sun-sensitive.
- Retinol / Retinoids – Amazing for anti-aging, but can make your skin photosensitive.
- Essential oils – Citrus oils in particular can cause phototoxic reactions when exposed to sun.
Always read your product labels—and if you’re using actives, double down on SPF.
🧪 Nano vs Non-Nano Zinc: What’s the Deal?
If you’ve dipped a toe into low-tox beauty, you’ve probably heard about nano zinc oxide in mineral sunscreens. Here’s the breakdown:
- Nano zinc: Ultra-fine particles that rub in clear (no white cast), but some worry about skin penetration and environmental impact.
- Non-nano zinc: Larger particles, often leave a white cast, but don’t penetrate the skin and are generally considered safer for reef and human health. (see Environmental Working Group reports, 2022).
If you’re choosing for kids or have sensitive skin, non-nano zinc is the more conservative choice. But both are effective UV blockers.
