In fact, studies have shown that retinoic acid can retain its potency for up to four years after the expiration date.

So if you have a bottle of tretinoin that is past its expiration date, it may still be effective. Of course, it is always best to use any medication as directed by your doctor or pharmacist. This means using tretinoin before the expiration date whenever possible.
