Can alarplasty fix a large nostril/alar crease and therefore make the nose look smaller? (Photo)

I'm not sure it's possible to do exactly what you've shown in the photoshopped image. (Which is way overdone anyways, it looks too too small in that image). Some improvement is possible, but I think you'd need to be asking yourself is this *really* that big a deal for you? Maybe your nose is not perfect, but who is? Remember, there's no such thing as a 'small' rhinoplasty, or 'minor tip work' etc etc.

Thank you for posting so many pictures.Your concern is understandable if you look at your skin thickness and probably a dermatologist could help you to work on it. Possibly things will get better with age as the skin becomes thinner.If instead you look at the shape of your nostrils, it is difficult to confirm by the pictures of you are really a candidate for alar base reduction.You are certainly very young and and surgical procedure should be taken very seriously, including a full understanding of outcome and consequence of any complication.I would suggest to seek your family support to start with and then consult a plastic surgeon with obvious experience in nose surgery as well as a dermatologist if your concern is about the skin thickness.I hope this will help.Best,
