Very heave texture.
Size: 6 Fl Oz (Pack of 1)
The texture is very heavy and greasy, and it leaves a white cast that takes quite a while to disappear. It’s probably fine for the body during beach days, but not for daily use — especially not on the face.

Really like this item for kids. Easy to apply with minimal white residue left. Do have to apply more frequently.

Works well even in water.
Was able to apply and use for hours even in water without reapplying. Usually burn but not with this. It does go on white and very thick but runs in.
