Do you actually know what's in your sunscreen? Is it protecting you—or harming you?
We've all been told to wear sunscreen. But much of what people believe about sunscreen is based on marketing hype, outdated science, or flat-out fiction. This guide will debunk the most common myths, explain why non-nano zinc oxide is the gold standard, and help you choose the safest option for your skin.
Is Higher SPF Always Better?
Short answer: No.
SPF 30 blocks 97% of UVB rays, while SPF 50 blocks 98%. SPF 100? Only 99%. The problem isn't the number—it's how people use it. Higher SPF gives a false sense of security, leading people to stay in the sun too long without reapplying.
The Truth: You need to reapply every 80 minutes, no matter how high the SPF.
Recommended: Waxhead Sunscreen Paste SPF 30 — Reliable, sweat-resistant protection in a pocket-sized format.
Are Chemical Sunscreens Safe?
No—and the FDA agrees.
Oxybenzone, avobenzone, octocrylene, and others are absorbed into the bloodstream within hours of application. These chemicals can disrupt hormones, trigger allergies, and degrade into carcinogenic compounds with sun exposure.
Better Choice: Non-nano zinc oxide stays on top of the skin, reflecting UV rays without being absorbed.

Is Zinc Oxide Really That Effective?
Absolutely.
Non-nano zinc oxide is the only active ingredient that provides broad-spectrum UVA and UVB protection. It's also photostable—it doesn't break down in sunlight like chemical sunscreens do.
Unlike titanium dioxide, zinc covers the full UVA1 range (the rays that age skin and increase cancer risk).
Try This: Waxhead Baby Sunscreen — Safe enough for babies, strong enough for adults.
Do You Still Need Sunscreen on Cloudy Days?
Yes.
Up to 80% of UV rays pass through clouds. Even on overcast days, your skin is vulnerable to long-term sun damage, especially UVA rays that penetrate deeply.
Pro Tip: Use zinc-based sunscreen daily, even in winter. Your skin ages year-round.
Recommended Daily Shield: Waxhead Daily Tinted Sunscreen — All-day wear, no ghostly residue.
Is Sunscreen Bad for Coral Reefs?
Chemical sunscreens? Yes.
Oxybenzone and octinoxate contribute to coral bleaching and reef death, even in tiny amounts. Hawaii and several island nations have banned them.
Zinc oxide, when non-nano, is reef-safe. It doesn't bioaccumulate or damage marine life.

Is Spray Sunscreen Just as Good?
Not even close.
Sprays offer uneven coverage and often lack the mineral actives necessary for safe protection. They're also easy to inhale—a major concern with nanoparticles or chemical actives.
Use creams or sticks you can rub in. They last longer and ensure full coverage.
Best for Application: Waxhead Zinc Sunscreen for Body
Are All Mineral Sunscreens Created Equal?
Not at all.
Many brands market "mineral-based" formulas that still contain chemical UV filters. Others use nano-sized zinc, which can enter the skin and water ecosystems.
Only 100% non-nano zinc oxide offers full safety. Always check the ingredient list.
Waxhead = 25% non-nano zinc oxide. Nothing else.
Do Tinted Sunscreens Work as Well?
Yes—sometimes better.
Tinted zinc oxide includes iron oxides, which protect against visible light (HEV) and contribute to pigmentation and photoaging. They are essential for melasma, dark spots, and skin of color.
Smart Coverage: Waxhead Tinted Face Sunscreen
Is Sunscreen Just for Summer?
Definitely not.
UV exposure happens year-round. Snow reflects UV even more than water. Indoor lighting and window exposure can also contribute to long-term skin damage.
Year-Round Tip: Make SPF part of your daily routine, like brushing your teeth.
Do Darker Skin Tones Need Sunscreen?
Yes—100%.
Darker skin does offer more natural protection against UVB burns, but it's still susceptible to UVA damage, pigmentation, and skin cancer.
Best Option: Tinted non-nano zinc oxide for daily wear. It protects without leaving a cast.
Can I Rely on My Makeup for SPF?
Only if you wear a LOT.
Most makeup with SPF doesn't offer enough coverage for full sun protection. You'd need to apply 7–10x more than usual.
Solution: Wear a zinc SPF underneath, then apply makeup over it.
Is Sunscreen the Only Way to Protect Skin?
It's just one layer.
Combine SPF with physical barriers like hats, UPF clothing, and shade. Even the best sunscreen isn't a force field.
Total Defense: Pair a Waxhead Hat with sunscreen.
Can You Get Enough Vitamin D While Wearing Sunscreen?
Yes.
SPF lowers vitamin D synthesis, but not enough to cause deficiency for most people. Plus, you don't need full-body exposure for vitamin D production.
Healthy Balance: Get sun on arms/legs a few minutes daily, or supplement.
Is Sunscreen Safe During Pregnancy?
Chemical sunscreens? No.
Hormone-disrupting ingredients like oxybenzone are risky. Pregnant and nursing people should choose only non-nano zinc oxide.
Safer Shield: Waxhead Baby Sunscreen is also great for pregnancy.
How Do You Know What Sunscreen to Buy?
Build a Better Sunscreen Routine:
- Daily: Use a facial SPF with zinc oxide, especially if tinted
- Outdoor Sports: Water-resistant stick or paste with 25% zinc oxide
- Kids: Avoid sprays or anything scented—use thick, rub-in paste or creams
- Beach/Travel: Go reef-safe with non-nano formulas only
FAQs
Q: What does 'non-nano' mean?
A: Non-nano means the zinc oxide particles are too large to penetrate skin or harm marine life. Nanoparticles, by contrast, may enter the body or damage reefs.
Q: Can I wear zinc sunscreen under makeup?
A: Absolutely. Our Tinted Face Sunscreen acts like a primer and protects all day.
Q: How often should I reapply?
A: Every 80 minutes, if you're sweating or swimming. Otherwise, every 2-3 hours is safe.
Q: What's the best sunscreen for toddlers or sensitive skin?
A: Waxhead Baby Sunscreen — food-grade ingredients, no synthetics, zero chemical actives.
Q: What does FDA say about sunscreen safety?
A: Only two ingredients are "GRASE" (Generally Recognized as Safe and Effective): zinc oxide and titanium dioxide. The rest are under scrutiny or have not been approved.
