This sunscreen body lotion is quite nice.
Style: Piña Colada
This sunscreen body lotion seems to work well. SPF 30 is the highest I could find with moisturizing capabilities. The smell is a bit overwhelming when you first put it on but it then goes away... so why the added scent. I wish it were SPF 50 and unscented. Otherwise I would have given it 5 stars.

Great stuff.

No weird smell or greasy residue, feels great on the skin. Tried it while on vacation (friend's lotion), and bought some when I got home. It is my go to now.

My favorite!
Best face sunscreen I've ever tried and I've tried a ton.
I have very sensitive skin and I've left this sunscreen on overnight and it has not caused any issues no breakouts.
I wish it had no fragrance but it doesn't smell the worst and my skin doesn't seem to mind.
My husband refuses to wear traditional sunscreen but he loves this one because of how light it feels on your face.
