I have had a previous surgery over 20 years ago. The long scar that was left behind has always been a big insecurity of mine. In addition, I have a large amount of stretch marks from pregnancy. If I go with a tummy tuck, I don't like the idea of having a new horizontal scar on top of what I already have. Decreasing my amount of stretch marks with the least amount of scarring is my main concern. If I could also improve the appearance of my current scar that would be phenomenal. Thank you.
