Hi Josh,
It seems to me that you are a Guru on the topic of retin-a so would you mind giving me your valuable suggestion. I have just started to use the green cream level 3. I used the Roc serum for some time long ago, didn't work for me.
Anyway this level 3 green cream seems too weak for me. Becasue it did not sting, no redness, no peeling. its like putting any other moisturizer/cream.
So do you think I sould go for a stronger version like level 6 or 9?

your valueable suggestion will mean a lot to me. thanks. have a great weekend.
