Stretch marks means pregnancy marks
Stretch marks are skin abnormalities that occur when the subcutaneous connective tissue is pulled apart (rapid growth through pregnancy, adolescents that grow too fast). The stretch marks themselves is not serious, but it is not pretty, and so really only a cosmetic problem. In the beginning stage, stretch marks look like parallel-running red lines, over time becomes that red color beige or skin colored (this process can last for years). In the market, cremes and lotions are available to try to prevent it and also there are laser treatments to work it away.
