The process of aging can cause skin to lose elastin and slow down collagen production.
Stretch marks (striae) are indented streaks that appear on the abdomen, breasts, hips, buttocks, or other places on the body. Stretch marks are very common and are caused by stretching of the skin often from rapid growth in adolescence, genetics, pregnancy, or weight gain. The severity is affected by several factors, including your genetics and the degree of stress on the skin.
