Stretch marks are indentations within the skin that result from damage in the dermal layer of skin. The only effective permanent “cure” for stretch marks caused by rapid weight gain, weight loss or pregnancy is skin removal. If your stretch marks are located in the lower abdomen, a tummy tuck will eliminate them because the skin is surgically removed. Stretch marks on the middle and upper abdomen may be improved but not eliminated, since this skin is pulled down and tightened during the procedure.
