Dr. Sugai Reviews: CoTZ Sensitive SPF 40 Sunscreen

Highly anticipated review of CoTZ Sensitive SPF 40 Sunscreen with only zinc oxide! After dealing with the big news about Purito and their SPF 19 testing in two laboratory settings, here is a nice refreshing reset to the world of sunscreen discussions. As you may know, I am a huge fan of mineral-based sunscreens and the majority of the sunscreens reviewed here are mineral-based with zinc oxide or titanium dioxide (ie I reviewed SuperGoop! Matte Screen before Unseen which is chemical-based). CoTZ stands for "Containing only Titanium and Zinc." The big question is: Does this zinc-only sunscreen leave a white cast? Please watch to see how it looks on my skin!
