beware the white cast [SEP] I bought this so I'd have extra SPF in additional to my normal sunscreen, to apply over my makeup on days when I get a lot of sun. It does the job and it's nice to have around, and the packaging is very convenient; I also use the mirror to apply my other makeup. On application, the product itself is pretty sticky, but it blends easily enough and doesn't ruin my makeup. But I can only give it 3 stars because it leaves a pretty terrible white cast-- and I'm a very white person. When I first apply it I think I look embarrassingly white. I certainly couldn't recommend it to anybody with a skin tone that's not very pale.
