Who is recommended Botox for a cobblestone chin complex?

I have been living in stress and avoiding taking photos my whole life because of the pebble-like chin shape that appears on the tip of my chin when I clench my mouth or have a blank expression. I happened to see information on a beauty community saying that just getting a light Botox injection on the tip of the chin can quickly smooth out this unnecessary muscle tension, and I was easily swayed by it.
However, since I have a short lower face and a slight tendency toward a receding chin, I am extremely worried that if I get Botox incorrectly, my chin might look even shorter than before or my facial expression might look awkward when I smile. Would someone like me, whose jaw muscles unconsciously develop excessively and whose skin surface becomes uneven, also see dramatic shape improvement effects from getting this "pebble chin" Botox?
I would really like to ask if there are any members who have regained a smooth, slender V-line by consistently getting Botox on their chin at Maypure if they experience any dull pain or bruising during the injections. I am also curious how long the clean effects usually last after a single visit to the clinic, and whether it is definitely more advantageous to choose an expensive imported Botox product from the start to prevent developing resistance from frequent treatments.
If a simple injection procedure taking less than five minutes could instantly and satisfyingly get rid of my ten-year-old facial shape complex, I would definitely visit you this weekend to get the treatment done flawlessly. I would be truly grateful if those of you who have already experienced dermatological procedures could pour out invaluable advice in the comments so that I can create a beautiful, sophisticated jawline that looks confident wherever I go.
