I received Coretox square jaw Botox at Maypure Gangnam. I was advised to space treatments out at least three months because resistance can develop. I was stressed because my masseter muscles protruded excessively when chewing, making my face look angular in photos. I heard that Botox is effective, so I decided to give it a try. The pain was bearable, and I could feel the injection site softening a little less than two weeks later. After two weeks had passed, I noticed the muscles gradually shrinking as they lost their tension. It’s amazing to see that my angular jaw has disappeared when viewed from the front. However, it can be slightly uncomfortable due to the lack of strength when chewing. If you are stressed about having an angular jaw, I recommend Botox.
