We all know that the skin has three main layers: Epidermis (the outer layer), Dermis (the middle layer) and Subcutaneous or Hypodermic (the deepest layer). The stretch marks form in the dermis when the connective tissue is stretched beyond the power of its flexibility. As a result, the collagen is weakened and its normal production cycle is hindered and damaged.
The culprit for stretch marks is usually pregnancy, but also there can be other reasons, such as sudden gain or loss in weight, rapid growth, heredity, and stress. Fortunately, there are several natural ways to reduce the appearance of unsightly stretch marks.
