Has anyone experienced a bump on the gravel road?

I was trying to make a reservation to get Botox between my eyebrows and around my eyes, but there's a Botox event for the chin.

I'm worried because the area under my lips and chin is very bumpy like gravel, and I've heard that Botox can fix it.

I've never experienced it before, so I'm 고민이네요.

I need to decide before making a hospital reservation. If anyone has experienced a jagged bump, please let me know what it was like.
