I went to the Advanced Dermatology Center and the aesthetician was a smooth talker and told me to get the whole Obagi system because all the products transition into one another. And that’s what I ended up doing cuz I was new to the skin system. But later on I read that many users just buy the important ingredients. I don’t know how persistent your derm will be, but yes, if you get recommended the CRX system, just buy the clarifying serum and night cream cuz these two products are the only ones that both contain hydroquinone.
By the way, what brand and SPF factor sunscreen do u use?
