I am using retin-a for wrinkles So far, after 4 months of NIGHTLY use, I have had amazing results without issue. My preference is now lower the dose not because of redness or irritation--I just want to know if I NEED to do this daily to maintain the results. Will I LOSE the amazing results if I go down to 2-3 times a week? I know the skin will stop improving but I am fine with the way things are. TO MAINTAIN what I have now, how often do I need to do this? Still every night or can I chill out?
