It seems impossible to narrow the nostrils without surgery, but it can be better. Hold the cartilage of the nose with your index finger and lift it up three times a day, or more frequently and pay attention. It's not the tip of the nose, it's nasal cartilage. After a while, you will find that your nose is stiff and your nostrils look better than before. Take a dead horse as a living horse doctor, and I wish you more and more handsome (beautiful).
