Mineral Sunscreen Review: Keys Solar RX Broad Spectrum Sunblock

Looking for a reef-safe sunscreen that uses only zinc oxide as an active ingredient? You’re making a smart choice!

Natural Mineral Sunscreens that are good but not great. Over 100 brands tested by one family.

My family has tested over 100 natural mineral sunscreens over the last 10 years, so we know what really works. This brand is pretty good, but in my opinion, if you’re looking for the cleanest ingredients and smoothest application, then head over to my ultimate guide to natural mineral sunscreens and grab one of my top recommended zinc oxide sunscreens instead. My standards are really high though, so this one is still pretty good. 🙂

You can read all the details below to find out why this safe sunscreen brand did not make my top recommended list.

2023 UPDATE: DISCONTINUED

Keys Solar RX Mineral Sunscreen Review Price Range: $$$$

EWG rating: 1

SPF: 30+

Active ingredient(s): zinc oxide (18%), uncoated nano particles

Other ingredients: Shea Butter 10%, Avocado Oil, Carrot Seed Oil, Black Cumin Oil, Essential Oil Blend, Purified Water, Vegetable Glycerin, Vegatable Wax, Rosemary Extract

Antioxidants added: ?

Where to purchase: Keys website, Amazon, and independent seller Angela Regali

Ease of application: +/- creamy, but rubs in about average for a zinc-based block; I like the applicator pump

Scent: great – smells like oranges!

Water resistant? Not at all, and it doesn’t claim to be

My experience: Keys Soap was the first zinc block we tested, and my 2-year-old daughter ended up with red bumps on her arms afterwards. It may have simply been as a result of her first exposure to the sun for an extended period this year, or an initial reaction to the zinc, but it never happened again with this or any zinc product. I’m not crazy about any sunscreen that isn’t water resistant, because we’re either going to be sweating or swimming if we’re in need of a sunscreen. It visibly ran down my friend’s skin as he sweated playing volleyball.

Star Feature: “Our nano-zinc oxide (ZnO) is uncoated to provide healing therapies associated with zinc oxide. The uncoated zinc has also proven to be anti-bacterial and antimicrobial and can reduce redness, rosacea, age spots and melasma.”

Other products: I got to test all sorts of little samples from Keys Soap, and I do love them all! They have great healing lotion for eczema and after sun, a bug itch spray that helped my son sleep when the mosquito bites were keeping him awake, and even shampoo and conditioner with zero chemicals. I use about 4 drops of the shampoo on my kids’ heads, and it all smells yummy like oranges.

Keys Soap on the left, Miessence on the right. The difference is striking! Can you see the the Keys is actually dripping down the skin just from sweat?

Pros

Cons

  • Not water resistant
  • Cause one child to break out in red bumps
