I had a lot of worries because my chin was vertically split. It's not a pretty chin for a womanㅜㅜ I went to a dermatologist for a consultation and they recommended filler. But it was expensive and my chin isn't that short, so I got botox for my gravel chin and my chin is almost gone!! And because of the volume of the chin muscles, it looked a bit less angular. I highly recommend botox.
