Stretch Mark Treatments
Stretch marks (striae) are indented streaks that appear on the abdomen, breasts, hips, buttocks or other places on the body. They’re common in pregnant women, especially during the last trimester. Stretch marks aren’t painful or harmful, but some people don’t like the way they make their skin look.
Stretch marks don’t require treatment. They often fade over time, with or without treatment. They may never disappear completely.
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
The cause of stretch marks is stretching of the skin. Their severity is affected by several factors, including your genetics and the degree of stress on the skin. Your level of the hormone cortisol also might play a role. Cortisol — a hormone produced by the adrenal glands — weakens elastic fibers in the skin.
Anyone can develop stretch marks, but some factors increase your likelihood of getting them, including:
- Being female
- Having a personal or family history of stretch marks
- Being pregnant, especially if you're young
- Rapid growth in adolescence
- Rapidly gaining or losing weight
- Using corticosteroids
- Having breast enlargement surgery
- Exercising and using anabolic steroids
- Having a genetic disorder such as Cushing's syndrome or Marfan syndrome
Stretch marks don't usually need to be diagnosed. Your doctor might examine your skin and review your medical history. If your doctor suspects an increase in your level of the hormone cortisol, you might be offered additional tests.
Stretch marks don't require treatment. They are harmless and often fade over time. Treatment can make them fade, but they may never completely disappear.
The following treatments are among those available to help improve the appearance and texture of stretch marks. None has been proved to be more consistently successful than the others.
Retinoid cream. Derived from vitamin A, retinoids — such as tretinoin (Retin-A, Renova, Avita) — that you apply to your skin may improve the appearance of stretch marks less than a few months old. Tretinoin, when it works, helps to rebuild a protein in the skin called collagen, making the stretch marks look more like your normal skin. Tretinoin can irritate your skin.
If you're pregnant or nursing, talk with your doctor about other treatment options, because possible side effects of retinoid cream may affect the baby.
- Light and laser therapies. A variety of light and laser therapies are available that might stimulate growth of collagen or promote elasticity. Your doctor can help you determine which technique is appropriate for you.
- Microneedling. This type of treatment involves a hand-held device with tiny needles that stimulate collagen growth. This technique has less risk of pigmentation changes than does laser therapy so is the preferred initial approach for people with skin of color.
