Stretch marks are the striae that are seen after a massive weight loss or pregnancy. Many people have tried to treat stretch marks with topical agents. Any agents which serve to increase skin tone will help stretch marks to some degree. Some doctors have been experimenting with laser surgery, however the results have been disappointing at best. Surgical resection of the area of stretch marks are the best treatment currently available. Prevention of stretch marks is extraordinarily difficult, if not impossible. Women get stretch marks because of genetic reasons rather than for anything that they have either eaten or done.
