Comic: Is Glycerin good? Or bad?

Ryosuke got a new face cream a couple days ago. When he was showing it to me, he was like “Oh – it says this cream has glycerin in it!” I knew I had heard the word glycerin before – but couldn’t remember the context. And for the life of me, I couldn’t remember whether that was a “good thing” (makes your skin look younger, repairs damage) or a “bad thing” (poison, kills you, etc).
