An implant inserted into the nasal cavity for correcting the shape of the nose, and more particularly, an implant including a core material part having flexibility and an outer skin material part having more flexibility than the core material part. The implant may correct the bridge of the nose just with a simple structure which is entirely inserted into the nasal cavity without being substantially exposed outwards, and may also correct the shape of the nose as desired by adjusting size, flexibility or the like of the core material part and the outer skin material part. Therefore, the shape of the nose may be simply corrected by inserting the implant without any surgical procedure, and during use for a long period of time, the shape of the nasal cartilage changes, which may give a plastic surgery effect to some extent.
