Zo is Dr. Obagi’s range. He also does the Obagi chemical peel too. Tretinoin is prescription but nothing else in that skin care range would be. They market the products as if they are better formulated than cleansers you can buy freely online but this isn’t the case.Different strokes for different folks as they say. They are considered “medical grade” as they have higher levels of active ingredients and they have to be “prescribed” for your skin.
I have never heard of Zo. These kind of products are only as good as the person prescribing them. I’ve had amazing results with image skincare, environ and alumier over the years. I’m a skincare junkie! They aren’t much more expensive than the over the counter brands like kiehls etc but give way better results. I’m 32 and everyone thinks I’m still early 20s. People also think ive had Botox when I haven’t. It works for me
Everyone is different as you say and I’ve tried cheap, mid range and expensive and I can’t say I found the expensive products life changing in any way. Tret on the other hand is the best thing I’ve ever used!
