In this Thinkdaily Tinted Face Zinc Oxide SPF 30 sunscreen lotion review, I test a very high performing sunscreen. Many thanks go to “K” for this sunscreen!
The Thinkdaily Tinted Face Zinc Oxide SPF 30 sunscreen lotion is a mineral sunscreen formula which contains Zinc Oxide at 24.25%. I just love these highly specific % concentrations…
Some things to note: The ingredients listed on their current website indicate they’ve changed their formula and packaging verbiage since I’ve tested this product. I was also not able to find a perfect match image of the tube that I have, and as such uploaded the “updated” one. The only differences between the tube I have (and tested) and the one I uploaded is that phrases “dermatologist recommended” says “100% mineral,” and “reef friendly,” says “light natural fragrance.” Everything else looks identical.
The Thinkdaily Tinted Face Zinc Oxide SPF 30 Sunscreen reduced 99.96% of irradiated UVA, 99.27% UVB, and 99.92% of total UVI. Excellent results for a SPF 30 formulation!

Prepared slide BEFORE testing
The Thinkdaily Tinted Face Zinc Oxide SPF 30 sunscreen was very consistent in distribution. This was due to the “higher” viscosity of the formulation (note the lack of pooling of sunscreen at the edges of the slide cover).
