A combination treatment using laser and subcision surgery would improve but not eliminate the scars on the nose. Our office specializes in scar therapy in Los Angeles.

What the picture shows is a depressed scar on the tip of your dorsal nose. The borders of the scar need to be leveled to the base of it. This can be accomplish in 2 ways. Sanding the borders to the level of the center with dermabrasion, or treated the center with fractional laser to help elevate the center. Those are your 2 best options.
Another technique that you could consider for your nasal tip is to have dermabrasion to resurface the skin. This is different than micro dermabrasion as the treatment provides a deeper level of treatment. The resurfacing can be blended to help with the transition from the treated to untreated areas.
I do this quite a bit for facial scars, even those related to prior skin cancer, and it can be very helpful in smoothing out the area.
