Stretch marks are caused when the skin rapidly stretches as a result of sudden growth at puberty, weight gain or pregnancy. The stretching causes the body’s middle layer of skin to tear, allowing the deeper skin layers to show through. The location of stretch marks varies depending on a person’s body type but typically occurs on the tummy, breasts, upper arms, bottom, thighs and shoulders.
