Bests & Worsts Reviews from Amazon

THIS IS NOT OBAGI PROFESSIONAL-C. Ive used obagi C for over 5 years (mostly from different dermatologist offices) and it always stings/tingles just a little bit, makes face a little flush and makes skin feel silky. this does none of that. Its not even the same color. I highly doubt there is any vitamin c in it. Maybe I will do a litmus test,id bet this stuff is very nuetral. I will see if serum discolors over time too. if you let real obagi sit too long, it does turn dark. Save your money. Im a real person, with real experience and this is just oil. I'm pretty pissed, want my money back.
