Stretch marks are one of the most common skin problems. The strangest fact about this skin issue is that unlike most of other problems, stretch marks do not pose any health hazard to the individual nor are they painful. That they look awkward and can’t be totally eliminated is a very different story altogether.
Scientifically speaking, stretch marks occur when the middle layer of the skin or the dermis is stretched to a point where its elasticity begins to break down. This further causes a small amount of microscopic bleeding, accompanied by inflammation of the tissue, which further brings about the much-dreaded raised reddish purple look that is seen at the spot of newly developed stretch marks.
Gradually epidermis, the outer layer of the skin also stretches a lot, making it translucent enough, so that you can clearly see the stretch mark forming. As these marks slowly heal, scar formation takes place, leaving behind a typical looking stretch mark.
