Is there any way to adjust nasal tip without going under anesthesia? (photos)

Yes, tip can be done under local anesthesia. It will not effect the remaining nose. The procedure is quick and recovery is quick as well.
Tip-plasty
Tip-plasty is a great procedure to address a bulbous tip only and leave the rest of the nose alone. It can be accomplished through an open or closed approach. The goal is to refine the tip and make it smaller and smoother.
In tips with strong cartilages but thin skin, all that is needed is removing some of the cartilage and softening the rest by gently crushing it (morselizing).
In tips with thick skin and lot of soft tissue or fat, the excess fat and soft tissue is removed along with removing some of the cartilage.

The tip can certainly be brought in some, but it's usually done under anesthesia. It's not like just chopping some off - the cartilages that make up the tip have to be dissected and refined, which is usually more than what can be done awake. Be sure to see a rhinoplasty specialist for consultation.
