Is Obagi Tretinoin any different to generic?
I have been using Obagi Tretinoin & Hydroquinone for 2 months & am having amazing results. Obagi is difficult for me to sustain financially though & I would really like to know if there is a difference between Obagi & a generic Tretinoin/ Hydroquinone as I can purchase generic for less than half price. Opinions differ, with most saying there is no difference, but others saying the vehicle they use is superior?? Please experts can you help me with this? Thank you in advance
