“finally, a sunscreen that doesn’t make me break out.”
i’ve avoided face sunscreens for years because they always made me oily or caused bumps. this one goes on smooth, no white cast, and actually feels good on my skin.
“used it on my baby and myself — love it.”
we’ve been outside a lot lately and this balm has been perfect. super gentle on my toddler’s skin and no weird chemicals to worry about. plus it smells amazing in that natural way.
“stayed on through sweat + surf.”
used this on a beach trip and didn’t burn once. went in the ocean and it stayed on better than most natural sunscreens i’ve tried. no stinging eyes either 🙌

The only stuff I put on my kids! I also work outside everyday, so sun protection is key. Great subtle sent and easy to apply.
A
Amazing product!! Stays on a long duration of time without reapplying, even in water! The best SPF protection I’ve used
M
I brought the Castaway Tallow and Zinc Sun Balm (the 2 oz jar) with me on two recent trips—Roatan and Mexico—and I’m beyond impressed. I applied it once in the morning before heading out for the day, whether I was on a boat, by the ocean, or relaxing at the pool. The only time I needed to reapply was on my shoulders, and even then, I NEVER got sunburned.
This balm is packed with high-quality, all-natural ingredients, which is a huge win for me. It’s the best sunscreen I’ve ever used—hands down—and I love knowing that I’m not putting any harsh chemicals on my skin. I feel so much better using this on myself and will feel completely confident using it on my grandchildren too.
Castaway has truly nailed it with this product. I’ll never go back to conventional sunscreen again.
A
I live in Hawaii so this is used daily. Feels much better than the chemical spray I used to spray all over my body.
M
Great product. I use this down in Florida for the first time and it’s amazing. It stays on for a long time and feels great on my skin. I love that these products are all natural.
