A stretch mark is considered a type of scar that develops because of stretching or shrinking of skin extremely fast in a brief period of time. This sudden change causes those elements that provide skin support including collagen and elastin to rupture and become disarray, which is the same mechanism as development of a scar. Stretch marks do not always look alike in different areas of the body or in different people. Depending on the skin type, pigmentation, and site of the stretch marks they can vary in size. Most often they appear as pink, red, or purple and the coloring gradually fade away over time.
Anyone can develop stretch marks, but some people are at higher risk of developing stretch marks, those include:
- Being female
- Pregnancy
- Having a family member with stretch marks
- Being overweight
- Rapid weight loss or weight gain
- Growth spurts during puberty
- Rapid muscle growth during strenuous weight training
- having any type of procedure that causes a stretching of the skin including breast augmentation
