I've been so stressed out because of my chin.. it's so good; The mouth is slightly protruding , but even the chin is short, so the mouth protruded . When I was choosing it, I was thinking about Restylane.. Since it's a chin , it has a high volume . If you are afraid of surgery like me, I recommend a filler ^^ When you get hit, it's stiff and slightly painful, like anesthesia at the dentist ;; There is no pain after 20 minutes ^^ haha
