Alba packaging stinks
Style: SPF 50, Size: 5 Fl Oz (Pack of 1)
Complete waste of money! I ended up tossing it out because it’s IMPOSSIBLE to use. You should be able to twist the top to lock/unlock and spray it. NOPE. The top just spins and doesn’t catch or you cannot twist it at all. It’s also virtually impossible to spray. I had to hold it against my torso and press with both thumbs to get it to spray. Meanwhile, it’s leaking, the bottle is getting slippery. And then the spray goes EVERYWHERE, it’s not a narrow spray but it’s as if you’re dusting crops. I tried to see if it needed a certain pressure point, two fingers, bloody hell it’s not a Magic Mouse you should be able to unlock and spray it with one hand. Anyway, Alba needs to do some QC on their packaging. The last pump lotion I got, the pump also did not work. It just spun and spun and could not be unlocked. I had to wash and reuse the pump from an old bottle.

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.

Reliable protection that stays put during workouts!
Style: SPF 50, Size: 8 Fl Oz (Pack of 1)
I’ve tried many expensive name-brand sunscreens, but this Amazon Basics version performs just as well, if not better. It’s become my go-to for morning runs and trips to the beach because it actually stays on even when I’m sweating. Why I gave it 5 stars: Non-Greasy Formula: Unlike other sport sunscreens, this one absorbs quickly and doesn't leave that heavy, sticky film on my skin. Actually Water Resistant: I’ve used it for laps in the pool and long hikes; as long as I reapply as directed, I haven't had a single sunburn. No "Sting": One of the best things is that it doesn't run into my eyes and sting when I start to sweat—a huge plus for runners. Great Value: You get a generous 8-ounce bottle for a fraction of the price of "premium" brands. The fact that it’s formulated without Oxybenzone is an added bonus for peace of mind. If you’re looking for effective, no-frills sun protection for an active lifestyle, you can't beat this. It’s a staple in my gym bag now!
