Heard that expired medications lose 10% of their strength each year? True? I have tube of Stieva-A cream 0.025% which expired in Oct 2012. Can I use?

In brief: Yes, you can

You have a brand of tretinoin (Retin A).
It will continue to be effective for many years. Even if it is a bit less potent it will work just as well. Different products are more stable or less with time. This is also dependent on the temperature at which they are kept.
