I've used this before and it smelled great this bottle smells like its expired. It is a great moisturizer but I don't think its supposed to smell like this.

Worked well near the equator
Style: SPF 50
I bought this product because I was going to be in the field for a month, outside, every day, all day, in Tanzania at high altitude. A severe sunburn would be hard to treat in the remote area we were in, but also I am very careful about protecting my skin from aging. I had to have mineral based sunscreen because as a whitewater kayaker I know it’s the only truly water resistant kind and it was going to be sweaty. And since I knew I was going to be putting it on every day, and we didn’t have running water in the field (bucket showers only) I didn’t want it to feel gross. (I really wanted to try the spray but I didn’t want to put anything pressurized in my luggage.) And I had already discovered the Coola face sunscreen (30spf version) which had impressed me with how silky smooth and not greasy it is. Now this IS greasier because it is a higher SPF. BUT I think this product is as good as you’re going to get with the protection you’re getting. Like I said, I’m a white water tiger, so I have used a LOT of mineral sunscreens. This was hands down the most comfortable one I’ve used. And it was effective. I didn’t burn once—only time I did burn was when I forgot to put it on one day toward the end of the trip, when we were out for just a couple hours—and I got the first 2nd degree burn I’ve ever had in my life. That was what this stuff had protected me from, all day every day, the entire trip. I did tan a little but I think that was mostly from the few times I was not covered during short bouts or it was cloudy. For my face I used the Coola 50spf face product.

Love this stuff!
Style: SPF 50
I use this every day and I love how it is frangrance free and creamy. I have a very fair complexion and I will say it leaves a slight white cast but it doesn’t bother me because it almost makes my fairness more creamy looking. My skin texture has improved since wearing it daily and no allergies from it. I highly recommend especially if you have fairer skin otherwise it may leave a cast .
