Your situation is caused by the depression in the middle of your face, and the specific part is the depression in the bottom of your nose, so your upper lip will protrude. As long as the depression at the bottom of the nose becomes full, the upper lip will not protrude beyond the lower lip. Generally, American puffed and Korean soft silicone materials can be used to fill the nasal bottom, but the injected materials will be absorbed by the human body, lasting about six months to one year. Prosthetic materials can maintain life-long effect without swelling after operation.
