Stretch marks are areas of skin that look like lines or stripes. They’re scars caused by tiny tears in the dermis layer of skin.

Stretch marks occur when the skin’s collagen and elastin fibers are stretched, like when a person grows or gains weight rapidly. Over time, they typically take on a lighter, scarlike appearance.

According to a 2013 analysis, between 50 and 80 percent of people get stretch marks. There are a number of treatment options for stretch marks. But while treatment may fade stretch marks for the most part, it won’t cause them to completely disappear.

After determining the cause of the stretch marks on your backside, your doctor might recommend a topical treatment. This is the most common method for treating stretch marks. Topicals include:

  • Tretinoin cream. Some studies have found tretinoin cream improved the appearance of stretch marks.
  • Trofolastin and alphastria creams. A 2016 review notes these creams can provide positive results.
  • Silicone gel. A small 2013 study found silicone gel increased collagen levels and lowered melanin levels in stretch marks.

There are various treatment options focused on stretch marks. However, keep in mind treatments can’t completely eliminate them. Options include:

  • Laser therapy. Laser therapy may help fade stretch marks. Typically, several weeks of treatment is necessary. It may take up to 20 sessions.
  • Platelet-rich plasma. According to a 2018 article, injections of platelet-rich plasma (PRP) can help rebuild collagen, making stretch marks less visible.
  • Microneedling. Also known as collagen induction therapy, microneedling makes tiny punctures in the top layer of skin to trigger elastin and collagen production. It often takes up to six treatments over about six months to maximize results.
  • Microdermabrasion. A 2014 study found that microdermabrasion had the same level of impact on stretch marks as tretinoin cream.

Here are some ways you can treat stretch marks at home:

Eat a healthy diet

Since diet can affect skin health, it’s logical that diet would play a role in stretch marks. To prevent stretch marks, eat a healthy, balanced diet. Make sure to get plenty of vitamins and minerals, particularly:

Try oils

A number of people claim oil can reduce or eliminate the appearance of treat stretch marks, including:

However, a 2015 review reports cocoa butter and olive oil didn’t demonstrate any positive effect.

On the other hand, a 2012 study indicated that the combination of almond oil and massage was effective in reducing the development of stretch marks in pregnant women. Researchers are unsure whether the positive effects come from the massage, oil, or both together.

Here are 12 essential oils to try to heal and prevent stretch marks.

Avoid corticosteroids

Avoid the use of corticosteroid creams, lotions, and pills. They decrease the skin’s ability to stretch, which can cause stretch marks.

Stay hydrated

Drink enough water — about eight glasses a day. If your skin doesn’t get enough hydration, it’ll be less resilient.
