The tip is pretty nice, a smooth stream of sunscreen comes out with minimal smearing all over the cap. The cap is a screw cap that clicks in place.
Makeup applies over this sunscreen and I've also mixed this sunscreen with the Skinfood Peach Sake Pore BBcream and it worked pretty well but by the end of the day if I rub my neck (where I apply the sunscreen + bbcream as well), I got the "eraser shavings" rolling off and yeah, I rub my neck a lot ^^ must be some kind of nervous habit or something.
I've used it for about 2 months now and I've had no breakouts as far as I am aware and I have very sensitive skin :) I don't know if this is a HG item or anything like that. After I'm done with this bottle I'll probably explore more sunscreens but for now it's definitely perfectly adequate.
