The human nose is a bony structure and the bones and cartilage tissue of the nose directly determine the shape of the nose. At around the age of 16, the bones and cartilage of a person are mature. If you want to change the shape of the nose after this time, it is very difficult to change it unless you go through surgery. In addition, even if you use a nasal clamp from the time when the bones and cartilage are immature, it may not necessarily result in a beautiful nose shape, not only will it not reduce the nose, but it may even affect the normal growth and development of the nose. The nasal area belongs to the cartilage tissue, if you use the nasal clamp for a long time, the blood vessels and nerves of the nose are easily compressed, and it is likely that the subcutaneous tissues and skin of the nose will be damaged, resulting in misalignment of the nasal tissue, causing congestion, scarring, swelling, and even ischemic necrosis, etc. In serious cases, it may also lead to chondromalacia, resulting in nose deformation and fracture. If the patient finds that the bridge of the nose is slightly higher and the nose is narrowed at the beginning of using the nasal clamp, this situation is only temporary and will return to its original state. Because the nasal cavity has a strong self-recovery function, it is impossible to reshape the nose by using a nasal clamp. In addition, the indiscriminate use of nasal clips can also affect the respiratory system, thus causing the occurrence of other diseases, and it is not recommended that candidates use them at will.
