My Nostrils Are Unequal in Size, Can I Do Anything About It?

Perhaps the left nostril (on the right side of the photo as we are looking at it - I never know whether the photo was taken in a mirror or with the camera pointed directly at your face) is slightly larger in circumference than the right. However, nobody else is going to notice this.  Even I, as an expert, have to examine the photo closely to see the difference. So one option is try not to focus on or worry about this too much.

However, if you need to have something done about whatever asymmetry there is, know that there are many things that can be done about the shape, circumference and width of the nostrils and a surgeon, with enough experience and skill, should be able to change the shape of one or both of your nostrils.  As an aside, I have never heard of any study confirming that obsessive cleaning of the nostrils will increase their size.
