Sunscreen Smarts: A Healthy Woman’s Guide to Safe Sun, Vitamin D & Non-Toxic Protection

Written By Alexis Fisher

As soon as temps hit the 70s here in Wisconsin, we’re out the door—and I know I’m not alone. But while we’re chasing the sunshine and soaking in every warm breeze, it’s important to understand how to enjoy the sun safely and naturally—without toxic trade-offs.

Whether you’re a busy mom or simply trying to live a more non-toxic lifestyle, this post will break down how to:

  • Support vitamin D production through safe sun exposure

  • Choose the best mineral sunscreen for your family

  • Avoid harmful sunscreen ingredients

  • Protect your kids’ skin without the chemical overload

Let’s dive into sun safety with a crunchy twist.

Unblocked Sun: How to Boost Vitamin D Naturally

Your body creates vitamin D when UVB rays hit bare skin. But most of us are blocking this essential process 24/7 with sunscreen, makeup, and even windows.

Here’s the fix:

Aim for 10–15 minutes of direct sun exposure on your face, arms, or legs every day without sunscreen (adjust for your skin tone and where you live). This helps:

  • Improve immune function

  • Balance hormones

  • Support mood

  • Strengthen bones

Pro Tip: Early morning or late afternoon sun is gentler, and a few minutes goes a long way. Morning sun is also great for you Circadian Rhythm - learn more about that in this blog post!

When to Apply Sunscreen (and How Often)

Once you’ve had your intentional vitamin D time, it’s time to layer on the protection.

How often should you reapply sunscreen?

  • Every 2 hours—especially if swimming or sweating

  • Use about a shot glass full for full-body coverage

  • Don’t forget ears, tops of feet, and lips!

Mineral vs. Chemical Sunscreen: What’s Safer for You and Your Kids?

Chemical Sunscreen Ingredients to Avoid 🚫

These are commonly found in conventional sunscreen but have been linked to hormone disruption, skin irritation, and more:

  • Oxybenzone

  • Octinoxate

  • Homosalate

  • Avobenzone

  • Octocrylene

  • Synthetic fragrance

Many of these are banned in Hawaii due to their impact on coral reefs—and they don’t belong on your skin either.

Why Mineral Sunscreen is the Safer Choice

Mineral sunscreens use zinc oxide or titanium dioxide to create a physical barrier that reflects UV rays, rather than absorbing them. They’re:

  • Gentle on sensitive skin

  • Reef-safe and eco-friendly

  • Not absorbed into your bloodstream ‼️

This makes them ideal for:

  • Babies and toddlers

  • Pregnant or breastfeeding women

  • Anyone avoiding hormone disruptors

Non-Nano Zinc Oxide vs. Nano: What’s the Difference?

Here’s where it gets crunchy (in a good way):

  • Non-nano zinc oxide = larger particles that don’t penetrate the skin, making them safer and more effective for topical protection

  • Nano zinc oxide = smaller particles that create a sheer finish but may be absorbed more easily by the skin (research still pending)

Best choice? I stick with non-nano zinc oxide for my daughter and opt for sheer mineral formulas for myself to skip the white cast.

Why Spray Sunscreen Isn’t Worth the Convenience

I get it—spray sunscreens are easy. But the risks aren’t worth it.

  • Inhalation danger: The particles can irritate your lungs (and your child’s)

  • Chemical propellants: Many sprays contain butane, propane, or alcohol

  • Uneven coverage: It’s way too easy to miss a spot

Stick with lotions, creams, or sticks for safer, more reliable coverage. 🧴

My Favorite Non-Toxic Sunscreen Products for Families

For Kids:

For Adults:

  • Beautycounter Countersun Daily Sheer Defense – Sheer, blendable, and clean - I’ve used this for years on my face and have really liked it… praying it comes back when BeautyCounter Reopens this summer!

  • Thinksport SPF 50 Clear Zinc Face Sunscreen - I’ve also been using this for a few years but will be opting for the clear version this summer!

Still unsure about what to choose? I get it - too many choices can feel overwhelming. I recommend heading over to EWG’s Sunscreen Guide to help you make the right choice for you and your family!

Sunscreen Hacks for Moms (That Actually Help)

  • Wash your hands after applying sunscreen—especially mineral formulas, which can dry out skin

  • Follow with a clean hand cream like Primally Pure or OSEA

  • Apply sunscreen to your face using a makeup brush or beauty blender for a smoother finish

  • Let kids apply their own with a stick to make it fun

Sunburn? Here’s a Clean Recovery Plan

Even with the best intentions, we all miss a spot.

Final Thoughts: Balance, Not Perfection

You don’t need to be afraid of the sun—but you do need to be informed. Build your day around smart sun exposure, protect your skin with safe ingredients, and teach your kids how to love and respect sunshine the healthy way.

One small swap at a time, you’re protecting your family and reducing your toxic load.
