How did the nostrils come out? Many are hereditary, born like this, and a few are caused by some bad habits. They often pick their nostrils with their hands, or hold their noses with their hands, so that their nostrils move upward and are easily exposed. Everyone should get rid of bad habits.
In fact, even if the nose is exposed, it is not necessarily ugly, and there are also beautiful women who show their nostrils. The nose is only a part of the five senses, so it looks good. You can't just judge by your nose, you should combine your face with all the five senses.
