Great product, works well. My only complaint is I believe it might have stained my white, UV blocking running top. After the first use there was yellowing all long the neckline and sleeves where I either accidentally got it on the shirt or sweating transferred it on. I’ve never had this problem before and can’t 100% be sure the lotion itself is to blame but it is the only thing that changed from other times I ran in that top. I haven’t noticed this problem with other tops so I’m not sure if it was the material itself or the color that reacted. Still going to give it 5 stars because I like the product.

My favorite.

Size: 6.76 Fl Oz (Pack of 1), Style: Lotion (SPF 50)

I love this stuff. It's non-comedogenic, so it doesn't break me out. I've noticed a considerable difference in my acne scars after using it for a couple weeks. It is a little greasy and there's a very slight white cast, but I don't mind because I just let it dry and then put some powder over the top. Plus, the cast is easy to rub in and makes my skin tone look more balanced (I am white, though). Hope this helps!

Good sunblock

Size: 6.76 Fl Oz (Pack of 1), Style: Lotion (SPF 50)

This is my go-to sunblock reconnect by my dermatologist. It has a good skin feel, and seems to do the job required.

Perfect protection for daily use

Size: 6.76 Fl Oz (Pack of 1), Style: Lotion (SPF 50)

This is my go-to sunscreen for my daily use. I have stuck to a strict skin care routine and at the end, it’s extremely important to have a sunscreen to seal the deal. And this does just that. It doesn’t leave that nasty white streaks from the sunscreen and goes on very nicely. Out of my months of using this I have never been uncomfortable with it and the smell is very refreshing unlike other brands of sunscreen. Most importantly, this doesn’t feel greasy or overly slick. Perfect balance.
