I have read some threads that you can get this without prescrip from some online PHARMS. Wow that is interesting. I have been using the one from NCN Pro Can someone help me out other than price what is the difference in this vs. the 0.1% gel from Alldaychemist? Is that an equivalent to the the NCN store? For those who have ordered from this online pharm any problems or suggestions?? Retin A has been one of my all time favs for skin care.
