Stretch marks are fine lines of thin stretched tissue that may appear on the body, often during rapid weight gain or pregnancy. Naturally, our skin is very flexible. However, during rapid growth, the production of collagen is disrupted (collagen is a protein found in our skin that makes up most of the connective tissue giving it a smooth texture). This leads to reddish lines on your skin with a rough texture that will eventually turn grayish or white before fading. Stretch marks can affect both men and women, however, they are more prevalent in women, especially during pregnancy.
Apart from pregnancy, often times people who are obese, people how have excess amounts of body fat, or even body builders can both develop stretch marks as a result of the rapid bodily changes that occur. Heredity can also play a role in the development of stretch marks. Some people are naturally born with dry skin that is less elastic than that of other people. In these instances, it will require less body change in a short period of time to develop stretch marks. Also, many steroids which are taken through contact with the skin can cause stretch marks in ones body.
