Sheet masks are formulated for one time use and down have the same preservatives as regular serums, they’re made to be opened and exposed to air for 10-30 minutes and then disposed. So honestly no it’s not really safe to store the leftover serum, you can’t say how they’ll keep and how fast they’ll go bad.

This is correct.
Michelle from labmuffinbeauty science has made a very thorough video on this topic

You can store is in a separate container preferrably with lock so it won’t evaporate and won’t be contaminated as well👍🏻🌸

Based on what I know I think its not really safe to do that since you can't really ensure that you store it in a safe and clean container also I once watched Michelle from Lab Beauty Muffin and based on her explanation storing excess serum is not a good thing to do since sheet mask actually designed as a one times use only
