Stretch marks or striae are long, narrow streaks or lines that form when the skin is stretched too quickly due to growth or rapid weight gain. The sudden or rapid growth of the body causes the stretching of skin layers beyond the elastic limit. This disrupts the collagen and elastin skin fibers resulting in the formation of stretch marks. These marks usually appear in the skin's dermis layer and on the surface of the stomach, thighs, hips, breasts, upper arms, and lower back. Stretch marks do not pose serious health issues, but it impairs the look and lowers an individual's confidence and self-esteem.
