I LOVE spf 100, I know people like to say anything above 30 or whatever is pointless but let me say, when I use spf 100 I don't tan at all (and I DON'T want to tan, I'm Asian and the kind of person who walks outside for 5 minutes and I'm visibly slightly darker) and my husband is white and burns if out in the sun too much but this stuff not only prevented burn but I think also prevented tan for him too 🤷🏻‍♀️ I think these bottles are also awesome to be able to fly with too, we bought a few for our Punta Cana trip and we didn't tan or burn, and we only used a little over one bottle for 5 days (we only wore when we'd be out in direct sun a few hours each day, and my outfits didn't show a LOT of skin so less surface area). I hope this company continues selling this product, it'll always be my go to for travel sun screen now :)

Feels great on skin, but wish it was a larger amount.

Size: 3 Fl Oz (Pack of 1), Style: SPF 100

I haven’t tried this in the sun yet, so I can’t attest to how it works as intended, but so far I have tried it on my skin to see if it is as thick and white as others. It goes on very easy and smooth. I do not see a noticeable white cast and it soaks into the skin quickly. I am hoping it works well in the sun because I will repurchase. I just wish it was a larger amount.
