Bests & Worsts Reviews from Amazon

I have been using Obagi Professional C Serum for years. I’ve always purchased it from my dermatologist but when I saw it on Amazon, I thought, how convenient! It was sealed & in the Obagi box but after breaking the seal & opening the bottle, I immediately noticed it was lighter color color & much thinner than what I have purchased in the past. In other words, I think it has been watered down!!! Buyer beware!!! Convenience is not worth it ~ I’ll make the 35 minutes drive to the doctor from this point own. NOT HAPPY & TRULY DISLIKE DISHONESTY!!
