Find out the symptoms of and treatment for this painless condition that causes streaks on the abdomen, breasts, hips, buttocks and thighs.
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:
See your health care provider if you're concerned about the appearance of your skin or if the stretch marks cover large areas of your body. Your health care provider can help determine the cause of the stretch marks and discuss treatment options.
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 is a hormone produced by the adrenal glands. It weakens elastic fibers in the skin.
Anyone can develop stretch marks, but some factors increase your likelihood of getting them, including:

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 health care provider about other treatment options, because possible side effects of retinoid cream may affect the baby.
Work with your health care provider to choose the right treatment or combination of treatments for you. Factors to consider include:
