At first, after a few months of receiving Botox, my chin muscles grew again, but
 
after several years of continuous use, the muscles themselves shrunk(?) probably because they were not used at all, and even though I increased the number of Botox treatments, my chin did not feel as big as before.
 
I didn't notice it, but when I looked at old photos, I noticed that my face shape had changed. This thought came to me as it felt so real, but is it really like that??
