How long it would take for my skin to stop being flaky and peeling?

The flaking and irritation are different for each person. Since you're slowly upping the percentage, I would think that within a matter of a few weeks, it should resolve. If it is too bothersome for you, you can always reduce how often you use it. For example, every other evening could help cut down on some of the flakiness.For more information: mahjouricostmeticsurgery.com

Thanks for your question.  When in doubt, always ask the prescribing physician's office.  Your skin will likely return to normal in a couple of days.  In our office, we normally start our retinol patients using it 2 nights a week.  If it is well tolerated, we add a night each week.  Our goal is every night, but not every patient can tolerate it.  Always avoid the area around your eyes.  Best of luck.
