Good quality
This product is very good. It smells weird but it’s not bad. It works, I applied it once and got a bit darker. About the packaging it could’ve been handled better, one of the bottles spilled a little bit and it was everywhere

My favorite moisturizer with SPF
Color: Untinted (1.7 oz)
Great mineral sunblock. One of the few mineral sunblocks that is easy to rub in so you don't look like Caspar the ghost after you apply it. Great natural ingredients. My only wish is for Clean + Kind top also make their daily moisturizer with SPF in a stick

Pretty good
Color: Tinted (1.7 oz)
This tinted spf checks a lot of boxes for me, but the smell when you initially put it on isn’t good.. (but then it goes away). I like that’s it’s not too matte and not too oily.

Unicorn sunscreen
Color: Tinted (1.7 oz)
I've used at least three bottles of both the body and face sunscreens by this line. It's honestly a unicorn sunscreen. Actually clean ingredients, over 18% zinc oxide, which apparently is the minimum needed to actually combat harmful rays, affordable, actually sinks into the skin and doesn't leave a white cast, AND my kids don't complain when I apply it to them. I use very high-end facial products and I've added this very affordable sunscreen to my daily routine and have been extremely impressed. Highly recommend and I'm so glad I found it.
