My nose has indentations on both nostril alar rims, but my nose looks fine.

There are techniques in rhinoplasty surgery that can help with alar rim retraction.   Whether or not these would be helpful for you is not possible to tell without having photographs of your condition. In addition and in person consultation would be necessary to determine the best approach for helping you with  your concern.  Best regards, Dr. Weiss 

Thanks for your question. 
It is difficult to say without seeing any pictures. I would recommend an evaluation with an experienced rhinoplasty surgeon.  I wouldn't worry about whether it's easy or complicated- that often depends on the surgeon.  Its more important to have a frank discussion about your concerns and the possible treatment options he or she can offer.  Best of Luck 

A full set of facial photographs are required to make a determination about what may be causing the dents on your nose. The nasal tip cartilages can sometimes be inverted/ concave which will require cartilage grafting techniques. The cartilage is usually harvested from inside the nose and grafted to this area to give a smooth contour.
