That’s what the sarcasm flag is there for: “/s”
which you put at the end of the specific sarcastic expression.
Some people just have trouble understanding sarcasm. Be it, because the intended tone is not understood by the reader due to the mere text medium, or because someone has trouble understanding irony and sarcasm due to being neurodivergent.
For irony and jokes I use “/i” and “/j” respectively in a similar manner.
In the context here, I would have just written:
“Sand is mostly shed human skin. /j”
