What is the Best Option for 1-2 Year Old Stretch Mark Reduction in the Abdominal Region?

I have marks from my first pregnancy and am trying to research procedures before the birth of our second baby in a few months time. I really would like information on laser procedures used to reduce scarring and stretch marks, such as chemical peels. Is this an option for stretch marks? I have MANY thin white ones and some thick purple/white lines on my tummy. I also want to find out if it is possible to have a tummy tuck with a minimized scar, or to treat it with laser treatment later.
