It Works!
Size: 16 Ounce (Pack of 1), Style: SPF 50
My favorite sunscreen. Smells incredible. Reminds me of the beach every time I use it. Which is daily. Summers are brutal in the south and I don’t get paid enough for a farmers tan. Alba has saved me. I’m hooked on it. Also the price isn’t horrible either. Sunscreen can be so dang expensive. You get your moneys worth.

Defective item
Size: 16 Ounce (Pack of 1), Style: SPF 50
I requested a refund or replacement as one of the two bottles that arrived. Has an issue with spraying. When I put it in the unlocked position, it does not spray I requested from the seller, but the seller wants to meet to provide proof and requesting me to upload a video. When I explained the defect, they told me to move it to unlocked position. I buy this sunscreen all the time for my kids so I’m aware of how to lock and unlock a sunscreen Unfortunately through buyer/seller messaging you’re unable to leave a video so I will unfortunately have to leave a review here. I hope the seller will resolve this defective item.
