<p>I have had to do a research on those before and and therefore think I can answer it. </p><p>Stretch marks comes when there is rapid gain in weight and this is mostly common in pregnant women. It can be seen on the abdomen as the baby bump grows. </p><p>Stretch marks are sometimes genetic. It the lady's mother had stretchmarks when she was pregnant, the lady will most likely have them too. </p><p>Stretch marks aren't that bad except for the fact that some people don't like them. It's just a tear in the inner layers of the skin due to the pressure from the baby-infused weight gain. </p><p>Stretch marks will most often become less visible as time progresses although some tend to linger. </p><p>Taking in lots of vitamins especially vitamin C will help fasten the fading process and also the application of cocoa butter. </p><p>Stretch marks aren't a visible in dark-skinned people as they are in fair people. That's an added advantage for the dark-skinned people. </p><p>Pregnant women should try to ensure less rapid gain in weight and should watch their eating pattern. </p>
