Leaves a noticeable white cast and does not rub in easily at all, would only recommend if you're going to be outside on a day when the UV index is very high, you have time to rub it in, and you don't care that people will see the white cast. In terms of sunscreen it does what it's suppose to do so I still gave it three stars, plus you won't find SPF 50 this cheap in any other product.
I use this sunscreen when I'm more interested in really great sun-protection than how I look that day. It leaves a white cast and is incredibly shiny, but as a high-SPF, physical sunblock that doesn't cause breakouts, it's hard to beat. I find that I can't really apply makeup over it well (too sticky and grabs product), so again, I save this for strenuous days outside, not daily use.
