Is Retin-A still effective with an expired expiration date?

Ive been suing Retin-A for years. I get it off my sister who has used it for about 20 years. Well, the tube she just gave me has a date on it that has already expired. I asked her about this and she said that its still good and that she has used tubes pleny of times that have already expired. For anyone that uses this, or has more knowledge of it, can you tell me, do you think the tube is still effective once its gone past the exp date?
