The nose does not get bigger and bigger as you pinch it. The shape of the nose is mainly formed by multiple paired, individual nasal bones and septal cartilage support. If you pinch your nose, it will not cause the nasal bones and cartilage to proliferate, nor will it change the shape of the scaffold formed by the nasal bones and cartilage, thus it will not cause the shape of the external nose to change, so the nose will not increase in shape due to pinching. Although pinching the nose will not cause changes in the shape of the nose, you should not pinch the nose, because pinching the nose will cause irritation to the skin of the nose and cause bacterial infection in the soft tissue of the external nasal skin. The skin of the external nose is rich in sebaceous glands and sweat glands, especially the skin at the tip of the nose and nose wings is a good site for boils and acne, and the skin of the nose is a dangerous triangle of the head and face, which can cause intracranial infection if infection occurs and is not handled properly.
