Mineral Sunscreen Review: CōTZ

I put my heart and soul into finding the best natural mineral sunscreen over the last 10 years. My family of 6 has personally tested over 100 reef-safe sunscreen options, putting two on our bodies every time we are in the sun.

Ease of Application: + This brand goes on very smoothly and probably has the best tinted version for children to use. In fact, my teenage son said, “Why aren’t all zinc sunscreens at least a little bit tinted so they rub in as well as this one?” I would put to this brand up there with Maelove as a great transition sunscreen. In other words, it is almost as smooth, quick, and easy to apply as conventional sunscreen.

The only situation in which CōTZ completely fails is if you are already sweaty and at the beach in the sand. That was an untenable situation for my husband who absolutely could not get CōTZ to rub in at all. Most other sunscreens were a disaster in that situation as well, to be fair, and the tinted version did at least stand a fighting chance on my husband’s face.

Scent: CōTZ is mostly unscented and really not remarkable in how it smells.

Water Resistance: We have not had any trouble with CōTZ coming off in the water. Face Moisture is rated for 80 minutes and Sensitive for 40 minutes.

My Experience: This brand has become a favorite for many in the family. And it is one that my daughter grabs exclusively whenever she has the opportunity. She even recognized it after 6 months and said, “Ooh, that one’s my favorite!” We tested CōTZ quite extensively in many situations, and a number of times it definitely performed better than the other side in A-B testing. In fact, after a full day on the Florida beach, when every part of everyone got somewhere between badly singed and burned to a crisp, I did not get burned on my face, which had the tinted CōTZ on it, and my husband did not get burned on his arm, which had the white version. We call this a huge success.

Star Feature: This brand definitely rubs in so well that it’s exemplary and deserves a trophy in that category.

My Review: We at the Kimball household unequivocally recommend CōTZ, both tinted and white versions, for pretty much all situations, unless you’re already covered with sand. 🙂 We’ve found it to be extremely pleasant in every category. And most importantly, it works great! Just a note: this is a “lighter green” option due to the ingredient list.


  • Rubs in very well
  • Tinted version as well as white ones


  • Does not rub into sandy, sweaty skin
  • EWG rating of 5
