After pregnancy and child birth, or after losing weight many people lose the elasticity of their abdominal skin as well as the firmness of the abdominal wall muscles. This results in stretch marks, hanging skin folds, and a "pooch". No matter how much fat and weight they lose, or after many sit -ups they just can't firm-up their abdomen and can't get rid of their stretch marks. No laser treatment, cream, excises, or machine can remove the stretch marks and tighten the abdomen.
