Daily Staple Sunscreen
Size: 3 Fl Oz (Pack of 1)
I’ve been really impressed with this sunscreen—it’s become a daily staple for my face and hands. The SPF 70 gives great peace of mind, especially with regular sun exposure, and it feels lightweight rather than heavy or greasy.
It absorbs quickly and doesn’t leave that thick white cast, which is a huge plus for everyday wear. On my face, it layers well under makeup without pilling, and on my hands, it doesn’t feel sticky or transfer onto everything I touch.
I also appreciate that it holds up well throughout the day without needing constant reapplication (unless I’m outside a lot). Overall, it’s a reliable, high-protection sunscreen that’s comfortable enough to use every day.

Works well when properly applied
Size: 3 Fl Oz (Pack of 1)
I try to always buy the highest SPF that I can find. This one fits the bill. If you apply it thoroughly all over and then reapply every few hours, you shouldn't get burned. I've worn it to the water park numerous times now. I have very sensitive skin, and it's given me no issues. I even put it on my face, just being careful not to get too close to my eye area. Once it absorbs into your skin, it doesn't feel too sticky like some other sunscreens can. Just be aware that it will leave a white residue on your bathing suit if you get it on there, but I've always been able to wash it out and that's a small price to pay for proper sun protection!

Excellent product.
Size: 3 Fl Oz (Pack of 1)
Excellent product. The sun is extremely strong where I live, and I've been using this for several days now; it lasts a very long time on the skin. However, if you have very sensitive skin, I wouldn't recommend using it on your face—in my case, it caused a breakout. But for the neck, body, and arms, it’s excellent. I highly recommend it, and it doesn't leave a bad feel on the skin or an unpleasant smell. If you use it in the water, it is recommended to reapply every hour and 20 minutes, otherwise you might get sunburned.

Solid sunscreen!
Size: 3 Fl Oz (Pack of 1), Size: 3 Fl Oz (Pack of 1)
I just started using this sunscreen about a week ago. It doesn’t feel heavy on the skin, but as someone with a dark complexion, it will leave a faint white-cast at first. Simply just tap it into your skin more!

Non-greasy and absorbs quickly
Size: 3 Fl Oz (Pack of 1)
I really like this sunscreen. It’s very lightweight and absorbs quickly without leaving a white cast or greasy feeling like other sunscreens. I use it every day and it feels very comfortable on the skin, even under makeup.
It provides great protection and doesn’t irritate my skin. The size is also convenient to carry in a bag. I definitely recommend it if you’re looking for something effective and lightweight.
