Better now than before
Size: 4 Ounce (Pack of 1), Size: 4 Ounce (Pack of 1)
I first bought this sunscreen in May 2022, and I got it again now, June 2024. The product is different now and some of the changes are noticeable in the pictures I've included: new look and shape to the bottle, weighs a bit less (great for TSA if you travel), the ingredients are slightly different. What you can't see in the photos is that it definitely smells better than it did before and it goes on your skin clearer than it used to; it would make me look like a ghost before, whereas now, it just makes my face shiny. It feels kind of dry when you apply it, definitely non-greasy. It still holds up great while sweating and swimming. And it definitely does its job of protecting from sunburns. Overall, I'm happy with the changes they've made and I would recommend it to anyone looking for durable mineral sunscreen for sensitive skin.

No stinging eyes for 6 yrs
Size: 4 Ounce (Pack of 1)
Out of all the sunscreens I've tried (zinc or otherwise) Alba Botanica is the only one that has not stung my eyes. Been using continuously for around 6 years. 7-8 years ago tried Neutrogena zinc sunscreen. It didn't sting initially but started stinging 1 year after continuous use. And Alba Botanica zinc Spf 50 does leave a white cast, just less intense than Neutrogena zinc.

Great on paper, but milky
Size: 4 Ounce (Pack of 1)
Based on my research I think it's one of the best physical sunscreens. Highest active ingredient percent and good price. It is quite white and harder to melt in and I still tan quite deeply.

Too thick and Difficult to Spread
Size: 4 Ounce (Pack of 1)
I’ve been using this sunscreen for several years. It was getting a good rating from Environmental Working Group in terms of being healthy for the skin. However, I finally gave up on it because it is so thick and difficult to spread. There are other healthy sunscreens that are not so thick and chalky.
