Best sunscreen I tried. Be sure to rub it in and let it absorb into your skin.
Size: 6.76 Fl Oz (Pack of 1), Style: Lotion (SPF 50)
This is an excellent product that absorbs quickly and leaves no chalky white or thick oily residue. UVA and UVB protection at spf 50. Two out of four of the active ingredients are double the amount in other brands and it has more of the two remaining ingredients so I guess it’s not my imagination that it’s more effective than other brands I’ve used. No detectable odors. Has an ingredient to help sand from sticking but I haven’t been on sand so can’t comment on that. It left white marks on the edge of the neck of my black crew neck T-shirt when I didn’t rub the sunscreen in and let it dry. However the marks came out in the wash. It stays where you put it, but keep it away from the eyes. Expensive probably because there are more of the active ingredients. I use it only on my face and neck but it is the best sunscreen I have tried.

Best sunscreen
Size: 6.76 Fl Oz (Pack of 1), Style: Lotion (SPF 50)
Best sunscreen ever. No breakouts. No scent (crucial). Melts into your skin, lasts for a good while. Expensive but worth it.

Might stain certain fabrics?
Size: 6.76 Fl Oz (Pack of 1), Style: Lotion (SPF 50)
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.
