Stretch Marks


A stretch mark is a type of scar that develops when the skin stretches or shrinks quickly. Stretch marks typically show up as bands of lines running across the skin on the abdomen, breasts, hips, buttocks or other places on the body. Their color can range from purple to red to light gray or whitish.

Causes of Stretch Marks

The abrupt change causes the collagen and elastin, which support our skin, to rupture. As the skin heals, stretch marks may appear. Stretch marks are more likely to appear in times of:

  • Growth spurts that happen in puberty
  • Pregnancy, especially in the last trimester
  • Rapid weight loss or gain
  • Weight training along with rapid muscle growth
  • Genetics and history of stretch marks in the family
