Symptoms

Stretch marks don't all look alike. They vary depending on how long you've had them, what caused them, where they are on your body and the type of skin you have. Common variations include:

• Indented streaks or lines on the abdomen, breasts, hips, buttocks or other places on the body
• Pink, red, black, blue or purple streaks
• Bright streaks that fade to a lighter color
• Streaks covering large areas of the body

When to see a doctor

See your doctor if you're concerned about the appearance of your skin or if the stretch marks cover large areas of your body. Your doctor can help determine the cause of the stretch marks and discuss treatment options.
