Stretch marks become visible on the body in many various places for a number of reasons. Stretch marks are caused when the dermis, the middle layer of your skin, is pulled to a point where its elasticity begins to become damaged.
During this process, microscopic bleeding takes place along with tissue inflammation, which creates the raised reddish purple appearance of newly developed stretch marks.
The skin is made up of three main layers:
- The upper or outermost layer is known as the epidermis.
- The innermost layer is the called the subcutaneous stratum.
- The layer that resides between the outmost and innermost layer is called the dermis.
A favorable amount is dedicated to allow the skin to stretch, however when it stretches beyond its capacity, the collagen production occurring in the skin is damaged. As a result your skins level of elasticity is seized and the order of fibers connecting the tissues are disturbed, leading to formation of unsightly stretch marks on the body.
Those that are most likely to develop stretch marks are pregnant women, those who lift weights, and adolescents. Pregnant women develop stretch marks most often during the later stages of their pregnancy when the baby is growing swiftly. Over half of pregnant women develop stretch marks on their belly. Other frequent places where stretch marks take place are the breasts, thighs and buttocks.
