This is kinda weird but I have noticed, particularly since I started vaping mostly 100% VG, that by the end of the day (I work at home on the computer all day), my face is sooooo shiny. I dont know if it is the vapor that surrounds me or if the stuff is coming out my pores or what. Its like i dunked my face in a bowl of canola oil or something (okay im exaggerating a little). On the bright side, I am so well moistured that I may never get wrinkles!
