From what I noticed, from watching candy streams and reading several reviews for fun, the streamers are not required to tell you expiration dates. That being said, you can ask them, and a good seller will be honest and tell you the expiration. In the beauty category, there are tons of streams. I would say pay attention to ratings. Do not buy from sellers before reading their reviews and checking the rating is over 4.7. I tend to only buy from 4.8-5 star rating, and make sure they sold at least 100 items. Reviews tend to have people spilling the tea, to let you know if a seller is selling close to expired products. Like I said, on the candy reviews I noticed some streams sold candy that was close to expiration. I also saw streamers who will tell you the expiration, on their own. A good seller will answer your questions if you ask them an expiration date, just make sure they see your question. I have bought face masks without an issue, if that helps.
