BEST sunscreen! No greasy/sticky residue!
Size: 6 Fl Oz (Pack of 2), Style: Lotion
I HATE putting on sunscreen! They’re always greasy yet somehow leave your skin feeling sticky at the same time (especially the spray on kinds)?! Most of them have a super strong smell, and even if it’s a good smell it’s so strong it ends up giving me a headache. A couple years ago Coppertone came out with a whipped sunscreen that I was borderline obsessed with! It changed my life when it came to the dread of putting on sunscreen. It was moisturizing, but not greasy. It left not a hint of stickiness, and it didn’t not have an overwhelming smell! I was ecstatic! I had it set to auto deliver the double pack all summer long! My whole family and extended family also loved it! Well, the very next summer they discontinued it and my family and I (especially) we’re devastated! They didn’t even come out with something similar. It was just gone! Since then I’ve been searching for any kind of comparable sunscreen to no avail! I’ve tried them all! Then, about a month ago I found this one!! This is it!! It’s only as good as the coppertone whipped, but in some ways it’s better!! It’s not greasy or sticky at all. It spreads easily and has the softest, lightest, most amazing smell as well! It feels like I’m putting on my favorite lotion! Plus, no one in my family has gotten the slightest bit burned! Even my beautiful porcelain skinned 4 year old daughter who you have to drag off the beach or out of the pool when the sun goes down because she thinks she’s a mermaid! 🤣 I have nothing bad to say about this sunscreen!! I have stocked up just in case…. But Please please please don’t discontinue it!! 🙏🏻🙏🏻

Better than Shiseido for a fraction of the price
Size: 6 Fl Oz (Pack of 2), Style: Lotion
I bought this sunscreen for a trip to Florida but now it's my everyday sunscreen. My job includes driving around to body shops so my hands get a lot of sun, and I'm too embarrassed to wear driving gloves. I was using Shiseido's clear sunscreen stick (also SPF 50+) but had a slightly noticeable tan line at my wrist, both from my jacket and my watch so I wasn't sure if it was really working, despite the good reviews (and $$). This Banana Boat sunscreen feels so good that I decided to try it out for my hands every day, and it's fantastic. Smells good, not greasy at all it soaks right in, and the best part is my tan line is GONE. 10/10 please don't ever discontinue or change the formula.

The best sunblock I've found!
Size: 6 Fl Oz (Pack of 2), Style: Lotion
I absolutely love this sunblock. I have sensory issues with any type of lotion and sunblock, but this stuff is incredible. It really is so lightweight that once it fully soaks in (which only take a few minutes) it feels as if there's nothing on my skin. This is huge for me, cause I just can't handle the feeling of any other sunblocks I've tried, even some more expensive brands. On top of all that, it definitely protects my skin from the sun, doesn't leave a white cast, and doesn't feel greasy while applying it.
