DIY Sun Shield Balm (Simple, Mineral-Based)

There’s something about summer that makes you want to slow down a little… bare feet in the grass, long afternoons outside, kids who don’t want to come in.

And if you’re anything like me, you’ve probably stood there at some point holding a sunscreen bottle, wondering what’s actually in it… and if there’s a simpler option.

This is one of those recipes that feels good to make and even better to use. It’s not complicated. It’s just a handful of ingredients you can recognize, mixed together into something practical for everyday life.

It’s also the kind of thing you can keep in your bag, your car, or by the door… ready for those last-minute “let’s go outside” moments.

What You’ll Need

• 1/4 cup coconut oil

• 1/4 cup shea butter

• 2 tbsp beeswax

• 2 tbsp non-nano zinc oxide

• 1 tbsp raspberry seed oil (optional)

• 1 tbsp carrot seed oil (optional)

How to Make It

Step 1: Melt the coconut oil, shea butter, and beeswax together using a double boiler.

Step 2: Remove from heat and allow the mixture to cool slightly. (This helps the zinc oxide mix in more smoothly.)

Step 3: Slowly stir in the zinc oxide, mixing well. Avoid inhaling the powder as you add it.

Step 4: Add the optional oils if using, and stir until everything is fully combined.

Step 5: Pour into a small jar or tin and allow it to fully solidify.

How to Use

Apply to exposed skin like a balm.

Reapply every 1–2 hours, especially during longer periods outdoors or after swimming or sweating.

A Few Helpful Notes

This is a mineral-based, physical barrier balm, not a lab-tested SPF product.

Zinc oxide is what provides the protective layer, so it’s an important part of the recipe.

You may notice a slight white cast on the skin, this is normal for mineral-based products.

Store in a cool place, as the balm can soften in warmer temperatures.

Why This Works

This blend combines simple, nourishing ingredients with zinc oxide, which sits on the surface of the skin and reflects sunlight. The oils and butters help it spread easily and keep skin feeling soft, making it a practical option for everyday outdoor use.

Prefer Not to DIY?

Some seasons of life just don’t leave room for making everything from scratch, and that’s okay.

If you’d rather keep it simple, you can grab a ready-made option (without the zinc oxide) like Sun Shield to have on hand for easy, everyday use.

And for those days when you’ve had a little too much sun, having something gentle and soothing ready to use can make all the difference.

Frequently Asked Questions

1. Does this DIY sun oil have an SPF rating?

No, this recipe is not lab-tested and does not have an official SPF rating.

2. Is zinc oxide necessary in this recipe?

Yes to act as a protection barrier, zinc oxide is the key ingredient that provides sun protection. Without it, the balm will not offer the same protective benefit. The oils can help support the skin, but they are not like a sunscreen.

3. What does “non-nano zinc oxide” mean?

Non-nano zinc oxide refers to particles that are not small enough to be absorbed into the bloodstream, meaning they stay on the surface of the skin to provide a physical barrier.

4. Why does this leave a white cast on the skin?

A slight white cast is normal with mineral-based; it’s a sign that the zinc oxide is sitting on the skin and doing its job.

5. How often should I reapply this balm?

Reapply every 1–2 hours, especially after swimming, sweating, or extended sun exposure.

6. Can I skip the optional oils?

Yes, raspberry seed oil and carrot seed oil are optional. They may provide additional skin benefits, but the recipe works without them.

7. How should I store this balm?

Store it in a cool place. Because it contains natural oils and butters, it may soften or melt in warm temperatures.

8. Is this safe for children?

Generally, yes, when used appropriately. However, always patch test first and consult a healthcare provider if you have concerns, especially for very young children.
