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.

This book was amazing!
Format: Kindle
I absolutely loved this book! Avery and Knox were beyond perfect for each other. Rebecca Jenshak did such an incredible writing this book and these characters. The brothers relationships in this family is wonderful. Everyone steps up to help take care of each other and it is heart warming. This book had low angst which I loved! I am really enjoying the start to this series and I cant wait to read the next book! The duet audiobook was incredible! Erin Mallon and Teddy Hamiliton did a fantastic job bringing this book and these characters to life! I highly recommend this book, audiobook, and series!

Banter, a bit of angst, found family, and a hot, tattooed bad boy who’s really a totally softie
Format: Kindle
This was a fun, easy read. It has all the things I love in a sports romance...banter, a bit of angst, found family, and a hot, tattooed bad boy who’s really a totally softie. Knox is kind of a mess at the start. He’s super talented, but has a reputation problem after getting kicked off his motocross team. He’s desperate for a second chance, which leads him to Avery, a former Olympic gymnast recovering from an injury. She’s trying to get her confidence back, and somehow these two end up helping each other. They can't stand each other at the beginning. He says ALL. THE. WRONG. THINGS. Evenutally, their friendship builds into something more. It felt natural and sweet. I liked that they both had their own stuff going on. Avery’s inner struggle was really relatable, and Knox’s bond with his brothers, especially with Flynn, added a ton of heart to the story. The beginning was little slow, and the ending felt a little rushed. Overall, though? I had a great time with this book.
