I have stretch marks on my boobs, what is the best way to get rid of it?

Not many options: There are a few laser type treatments that claim to improve the appearance of stretch marks. The only thing that is predictable is to excise them, depending on the location, much as you would in performing a breast lift. So if they are located around the nipple or under the breast that may be an option. If on the upper or outer breast the laser treatments may be beneficial.
