In this article, I will give you some insights on how to prevent stretch marks. Foremost, you have to understand first what are stretch marks and why they occur in the first place. Stretch marks are scars that are left behind in the skin when it is overstretched or simply when they are stretched to their utmost limit. It happens when the fibers in the dermis or the middle layer of the skin have broken down. The stretch marks often occur during the pregnancy period, extreme weight gain and loss, body building and in puberty. These scars are mostly seen in areas such as the abdomen, buttocks area, breasts, legs and arms too. Stretch marks appear first as red and eventually after some months, it will appear as color smoky or pale white.
