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.

Worked great
Style: SPF 30, Size: 3 Ounce (Pack of 1)
My skin is very sensitive to the sun. My skin does not tan I sun burn quickly! I love this sunblock because according to the ingredients it's reef & sea animal friendly. I found this product didn't leave a very noticeable white cast on my skin. I was able to blend it with very little noticeable white cast. I didn't find it sticky or really rubbing off on my clothes or bathing suite. In respect to all the things I mention it was all at a very minimal notice. For me it didn't have a smell of any kind. I used this product on vacation in Mexico. I tried & stayed out of the sun as much as I could. I went on a Mayan ruin tour following a snorkeling excursion & did not get a sunburn! Usually for that long period of time in the sun I would have received a light sunburn using other sunblocks but instead I actually got a light tan! I did apply this product on my body & face. I have to say this is my 1st time using this brand & it worked super well for me. :) *Just FYI when I applied this product I didn't need to apply to much if you do its going to obviously leave a white cast. I only applied as needed through out the day. Also make sure you give it time to sit to soak into your skin before putting on your clothes. After all you do have to wait a few min after applying before going out in the sun. That's any sunblock directions.

Finally! A sunscreen that works and does not burn my eyes.
Style: SPF 30, Size: 3 Ounce (Pack of 1)
I am unable to use chemical or hybrid sunscreens on my face because they "melt" and destroy my eyes. Living in the south means daily sunscreen year-around is a must - having found this product is a godsend. Unscented, no chemicals to discolor my clothes, no titanium dioxide so no purple-white ghostly cast, easily rubs in. Simply perfect!!!

Effective Mineral Sun Protection
Style: SPF 30, Size: 3 Ounce (Pack of 1)
This mineral sunscreen does a great job at blocking the sun. It applies smoothly, although it does have a slightly pasty texture which is typical of mineral sunscreens. I love that it was on the thinner side for consistency which makes it easy to apply evenly. We used it extensively last summer and it kept us well protected. We'll definitely be using it again this summer!
