Mineral Sunscreen Review: thinksport SPF 50+

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.

Water resistant? Seems to do fairly well

My experience: The texture of thinksport is very standard, exactly what you expect from a sunscreen I’d say. At first I thought it wasn’t rubbing in well at all, but after a minute it really did well, only about a 1-2 on the “ghostly” scale of 1-10. Winking smile It’s not greasy at all.

I really like the light citrus scent personally.

On the water test, it seemed to bead up, but was still no. 3 out of 4 of the batch of new brands from 2014 that I was testing all at once. I would guess it would do fine while swimming, but we didn’t get warm enough weather to test that yet (I’ll update this post if we learn any differently as the summer wear on…I mean, begins).

As for ingredients, I’m a bit disappointed. I had to look up a ton of them!

The capric/caprylic triglycerides might be fractionated coconut oil or might be “glycerin and caprylic acids,” is rated a 1 at EWG but with limited data. It is approved for use in food, as is sorbitan stearate, another ingredient. Caprylic acid is a fatty acid from milk or coconut oil. Those sound fine, but I’m not super thrilled with dimethicone, a silicon-based polymer rated 3 at EWG. Three is okay, but pushing it. I couldn’t find any data on polyglercerol-10 laruate and am starting to wonder if it’s misspelled.

The ingredients are a bit of a mystery in another way, since this one on Amazon looks like the right tube but has a ton of different ingredients, and the ingredients on this one are quite a bit closer but still not exactly matching my tube.

Star Feature: The texture is nice…


  • Good texture
  • Nice citrus scent


  • Potentially unsafe ingredients
  • Confusing labels
