I've been using this oil for about two weeks now and all I can say is that my skin is glowy and clear! It took about a week to clear up my old acne, but since then I haven't had any new breakouts, my blackheads are disappearing, and my old acne scars have even started to fade. This really is a do it all serum. I'm so glad I found it. This along with the Marie Veronique Treatment cleanser and oil are giving me the best skin I've had in years!
