Mineral Sunscreen Review: Keeki

Looking for a reef-safe sunscreen that uses only zinc oxide as an active ingredient? You may want to keep looking!

Safe Natural Mineral Sunscreens that are just awful. Over 100 brands tested by one family.

With over 100 natural mineral sunscreens tested by my family of six in the past 10 years, we’ve had our share of miserable failures. White out? Paint drying? Sticky, chalky, makes you look like an alabaster statue or Casper the ghost?

I will tell you this: it’s entirely possible to find a zinc oxide sunscreen that is reef safe, really works, and goes on smoothly.

This brand is not one of them.

Read the full review below to find out all of its transgressions, and then be sure to go to my ultimate guide to natural mineral sunscreens to find a safe sunscreen that really works.

Ease of application: not that great, a little sticky too

Water resistant? rated to 40 minutes

My experience: Rejected! The ingredient OM Cinnamate is not a mineral ingredient. It’s a conventional chemical sunscreen rated 6 (moderate hazard) at EWG, has hormone-mimicking effects in lab animals and has been found to be persistent in breastmilk. #greenwashing at its finest!

Also, before I noticed this fatal flaw, it didn’t rub in all that well anyway and had the “paint drying” effect.


  • None


  • OM Cinnamate is a chemical sunscreen ingredient with EWG rating of 6
  • Streaky, “paint drying” effect

Wondering if this one is the very best natural sunscreen for your family?
