Best method to get more symmetrical alar base/nostrils? (Photos)

It is very difficult to fix nostril asymmetry. Alarplasty can achieve it some times but not always. In your case seems like there is a deviation of the nasal septum. Correcting that will help with the shape of the left nostril but bringing the right nostril down might cause more deformity or asymmetry. It is best to leave it alone as the risks are higher than the rewards.

Alarplasty is a very fine and quick procedure that can narrow the nostrils and reduce the flare to soften the appearance. It has other names as well like ‘Weir Excisions’ or ‘Nostril Reduction’. However, it is important to note that asymmetry of nostrils is common and cannot be corrected with alarplasty. Visit the alarplasty website to learn all about it.
