The reality is, anytime an incision is made into the skin a scar will result. A scar by definition is the seam where the skin heals back together. It's the seam itself that can vary-from a hairline scar that is barely perceptible to one that is red, raised and hypertrophic or, at the most extreme, a keloid.
What a good plastic surgeon can do is to make it inconspicuous by putting it in a discrete place and minimizing the scar itself. But, take note, even a good surgeon is at the mercy of the healing process. The fact is, some patients are more susceptible to scarring. (This is often determined by your personal history of scarring: If you've never had any problems, chances are you'll continue on that same path, and vice versa.)
The good news is that new and innovative treatments are in development to manage less-than-ideal scars. In fact, Dr. Few will be giving a presentation at the annual meeting of the American Society of Plastic Surgeons in Denver this September on an injectable substance to limit scarring.
