Great quality
Size: 6 Ounce (Pack of 1)
Thinksport SPF 50+ Mineral Sunscreen with Zinc is a reliable, high‑protection option that feels lightweight and non‑greasy on the skin. It applies smoothly without leaving too much white cast for everyday use, and I love that it’s mineral‑based with zinc for strong UVA/UVB defense. Great for active days outdoors. Highly recommend for sensitive skin and safe sun coverage!

Brown skin approved!
Size: 6 Ounce (Pack of 1), Size: 6 Ounce (Pack of 1)
Does not leave a white cast, feels very light on the skin. Scanned on Yuka and was a 86/100 green zone! It’s so hard to find a sunscreen that isn’t trying to poison you, scanned all the sunscreen at Walmart and were rated a 1/100 through 6/100. Which brought me to Amazon. Thinksport has my vote on goodness and healthiness, would buy again!

My favorite... And I'm picky.
Size: 3 Ounce (Pack of 1)
I've become a little obsessed with sunscreen over the last past 5 years. I have olive skin and developed melasma after my first pregnancy. I learned the hard way that chemical sunscreens don't help if you have melasma - and they actually make the dark spots even worse. Also the active ingredients in chemical sunscreens (like Oxybenzone and Octinoxate) are absorbed by your skin, and may cause allergies, hormonal imbalance and be toxic overtime. After learning that, I started wearing only mineral sunscreen (active ingredient is zinc and/or titanium dioxide). These are not absorbed and works by creating a physical barrier that reflects the sun (some studies suggest that some nanoparticles of zinc may be absorbed by your skin, so to be really, really safe you should look for non-nano particles). After trying a few brands, I realized the sunscreens with only zinc in their formulas worked better than the blends with titanium dioxide, but this is just my personal preference I guess. And the higher the percentage of zinc, the better. Most pure mineral sunscreens out there are 10-ish % zinc, SPF 30, 40 min water resistant - which is ok. Thinksport goes beyond that: It's 20% non-nano zinc, SPF 50+, 80 min water resistant. It really can't get any better than that! The lotion is not extremely thick when compared to other sunscreens I've tried and I find it pretty easy to apply. As every zinc sunscreen, it does leave a little fine white cast, but honestly Thinksport is not bad at all! It smells nice, lightly citrusy - and the smell vanishes soon. And, it's not overpriced. Best I've tried so far.

Works but will Dry Out Your Skin
Size: 6 Ounce (Pack of 1)
I am a swim instructor at an outdoor pool and this stuff DOES work. I can apply it at the beginning of a 5 hour shift and while I have experienced light tanning it has protected against burning completely without reapplication. The white cast is significant though I don't mind it aesthetically, I know its there for protection . It does rub off on things though so consider yourself warned. Major Con: it is incredibly drying, and the soap needed to scrub it off is A LOT. That coupled with chlorine is a lot for my skin . Still on my sunscreen journey.

My Go-To Sunscreen for Every Outdoor Adventure!
Style: SPF 70, Size: 6.5 Ounce (Pack of 1)
The Neutrogena Beach Defense Sunscreen Spray SPF 50 has quickly become my favorite sunscreen for beach days, my Florida hot runs, and everyday outdoor activities. It offers everything I need in a sun protection product and more. Why I Love It: Excellent Protection: The SPF 50 broad-spectrum coverage does a fantastic job shielding my skin from both UVA and UVB rays. I’ve used it for hours on my runs, at the beach and never burned. Water & Sweat Resistant: I love that it stays on even after swimming or sweating. It’s labeled as water-resistant for up to 80 minutes, and it lives up to the claim. Quick & Easy Application: The spray format is super convenient. It applies evenly, dries fast, and doesn’t leave my skin feeling sticky or greasy. Great Scent: It has a light, fresh scent that smells like summer without being overwhelming. Gentle on Skin: I have sensitive skin, and this sunscreen never causes any irritation or breakouts like others have in the past. This sunscreen checks all the boxes; strong protection, easy to apply, and pleasant to wear. I’ve already repurchased it multiple times and always keep a bottle in my beach bag. Highly recommend for anyone looking for dependable and mess-free sun protection!
