Really nice sunscreen for a face
Style: SPF 70, Size: 8 Fl Oz (Pack of 1)
I love that this sunscreen is not greasy. Has a nice smell goes on easily over my moisturizer does not itch my skin washes off with open water at the end of the day. I use it on my face and anywhere else. The sun can shine arms, hands, and legs.

Black girl friendly!!!!!
Style: SPF 70, Size: 8 Fl Oz (Pack of 1)
I absolutely love this sunscreen! Im a black women with darker skin so its very hard to find sunscreen that doesnt make me a ghost and this one is so perfect. I tan super easy and dont want bad tan lines and this stops me from tanning when im just in regular clothes. This leaves my skin feeling super hydrated and it gives me such a beautiful glow im so obsessed i will NEVER use anything else. It smells ok, its not the typical sunscreen smell it has a slight fragrance to it. I have sensitive skin on my face and i use this on my face and i dont break out! Which never happens when i use a new product on my face, i typically break out. It goes on white but after rubbing it in after a few seconds it turns into this gorgeous golden glow.

Great protection with a lovely scent
Style: SPF 70, Size: 8 Fl Oz (Pack of 1)
I really like this sunscreen! It gives excellent sun protection and keeps my skin from burning, even during long hours outside. The texture is smooth and lightweight, and it leaves my skin feeling soft instead of greasy. I also love the light tropical scent — it smells like summer in a bottle! The only reason I gave it 4 stars instead of 5 is because it can feel a little thick when reapplying, especially in humid weather. Other than that, it’s a great sunscreen that does its job well and makes my skin look healthy and radiant.
