I have very small nose for a man how do I make it a little bigger without surgery?

Depending upon somebody's examination, injectable fillers may be considered for increasing the size of somebody's nasal appearance. Thank you for your question. Sincerely, Dr. Joseph

Fillers can be helpful. A procedure called a Non-Surgical Rhinoplasty may be a good option for you. Fillers can be used to reshape the nose without surgery. The results are temporary so there is no risk for permanent change to the nose. 

Hi and thanks for your question. Tough to tell without pictures, but you may be a good candidate for the 5 Minute Nose Job procedure. Improving the shape and volume of your nose would permit it to blend in with the rest of your face. I don't think that smoking stopped the growth of your nose.  
For the longest duration in a temporary filler, I usually use Voluma and it gives my patients 1.5 to 2 years. Voluma is also reversible at any time with a simple enzyme injection. Once the filler wears off and the nose goes back to its original shape, I give my patients the option of repeating Voluma treatment or going with a permanent filler like Bellafill. This is also a very safe and effective filler, but it does not get dissolved by the body, so it lasts for many years, or, with many people, the rest of their lives.
Whether temporary or permanent, Non Surgical Rhinoplasty takes 5 to 15 minutes to perform, involves minimal pain, minimal risk, no downtime or swelling and you can see the results immediately after the procedure.
If you do choose to have Non Surgical Rhinoplasty, make sure to find a physician who is very experienced in specifically this procedure and ask to see their before and after pictures. Hope that helps.
