I have 2 tubes of Rein-A Micro that have not been opened, but are expired. I don't want to use them if they would be harmful to my skin. If it's just a matter of not being quite as effective, I can live with that.
Thanks for any help,

Q: is unopened, expired Retin-A Micro harmful to your skin

My rule of thumb is that if it's expired you just don't use it. Yes, it is probably less effective but it can also have other degredation or mutation of ingredients. If it's just a couple of months I'd take a chance but otherwise toss it. I know they are expensive but it's not worth the chance of causing a skin issue.
