Best sunscreen brand! Fair, sensitive-skinned and rely on this
Style: SPF 50, Size: 5 Fl Oz (Pack of 1)
Alba Botanica is my favorite brand for sunscreen products and it checks all the boxes on my list: Excellent long lasting coverage, fine mist spray and easy coverage cream versions, great for my sensitive skin (no breakouts- I do NOT use it on my face though), the Hawaiian fragrance is pleasant, it’s reef safe (a big one for me as a snorkel/dive aficionado), and organic ingredients. The large size lasts 5 full days when on a boat all day in the Carribbean, and I only apply it twice (once in morning, and again midday.) I have fair skin, and I never burn. The spray version is, by nature of its aerosol capacity, a bit drying on the skin, but this is to be expected, and it creates a long lasting barrier. The cream version is a wonderful emollient, although not quite as long lasting. Best deal is only in the summer season at CostCo for a 2 pack... in my searches, Amazon has the best deal otherwise.

In most of all circumstances, this works
Style: SPF 50, Size: 6 Fl Oz (Pack of 2)
For Summer time and when playing and working in the sun, this is my go to sunscreen! I love how it is more natural than all the other ones out there. I have been sort of a spray on sunscreen connoisseur and this is the one that is my favorite. Also, if I have gotten a burn and put this on it, I believe it helps start the healing process on the burn I got. This is at least what I experienced multiple times last year. The only circumstance that this sunscreen fails miserably is in the Caribbean. I recently went on a cruise to that region and applied this sunscreen and it became evident that this and the other brands of spray on sunscreen do not work in Caribbean sun. The only sunscreen that works is the lotion based stuff that you rub into your skin. I have also consulted with friends on spray on sunscreen in the Caribbean and they all fail as well. So, this is why I say that it works in almost every circumstance.

spray nozzle needs work.
Style: SPF 50, Size: 6 Fl Oz (Pack of 2)
I purchased 3 of these cans. Only one of them worked and that one was ok. Sprayed well, smelled good and and protected my skin and even though it was hard to press it to work, we WERE able to use it, but the other three .............? They would not rotate to the unlock position, therefore they would not spray. My husband and I tried everything to get it to rotate. It seems both the top and bottom ring spin around effectively doing nothing. So to pay almost $40 for only one can to work is definitley not worth the money. Buy somewhere else.

Great product! Highly recommend! Worth the money
Style: SPF 50, Size: 6 Fl Oz (Pack of 2)
Our family absolutely loves Alba sunscreen! It’s light, not super greasy, and smells really good. Everytime I see it on sale, I buy more of it! My husband is a red head, and he has to wear sunscreen all the time, and he prefers Alba brand over any others. Great Product!
