This is an open topic for discussing. Skincare cream was wasted because there must be a little bit sticking on the inside of skincare packaging. People do not mean to waste (especially when it is very expensive eye gel/ serum, really do not want to waste any of it) but most of us have no idea about how to finish them up.

And there is another question. The waste (when the cream is going to run out) inside glass bottle must be more than in skincare plastic tube. I could cut the soft tube and finish up the final drop of cream. But for glass bottle, unless I broke it into pieces, otherwise I could not dig the cream out from its narrow mouth.
