Because stretch marks (striae) are common during pregnancy or after changes in weight, there is a huge market for makers of stretch mark products. You can find a variety of lotions, creams and oils to choose from, but have realistic expectations about the claims for these products before you buy them.
A Selection of Stretch Mark Products
The following products are popular and though reviews are mixed, they all have overall favorable consumer ratings.
Mederma® Stretch Marks Therapy Advanced Cream Formula
Mederma® Stretch Marks Therapy Advanced Cream Formula costs just over $25 for a 5-ounce tube. The cream contains:

On the company's website, reviewers mostly rated the cream three to five out of five stars and most reported that, though the stretch marks were still visible, there were noticeable improvements.
For existing stretch marks, the cream is claimed to reduce the appearance and smooth the texture of stretch marks in four weeks, if applied twice a day. During pregnancy, the company recommends starting the cream in the second trimester. According to Mederma, the product softens the skin to prevent it from stretching and tearing, thus preventing stretch marks.
Mederma Clinical Study
This is the only product that was evaluated in a clinical trial. In 2010, the Mederma company funded a study which was reported in the journal SkinMed. The investigators found that there was a significant difference in the appearance of stretch marks on the thighs of women after 12 weeks of treatment, compared to untreated stretch marks.

An eight ounce bottle retails for about $5.
Most of the companies claim that, if applied as directed, you should begin to see results in as little as two to three weeks, real results in about three months, and further improvement with further use for six months or more. The expected results include reduction in the length, width, depth and color of old or new stretch marks.
Most companies use the phrase "visibly diminish the appearance of stretch marks." Most of them don't claim that their product can make stretch marks disappear or prevent them.
According to the companies, more recent stretch marks will show better improvement than older ones. Reddish or purplish stretch marks will fade over several months. Keeping your skin moisturized during pregnancy may prevent the stretching and tearing of elastin fibers, which might explain the results seen with the products.
Despite marketing and consumer claims of the benefits of stretch mark products, there is little research evidence to support these claims or endorsements. Specifically, there are no studies that prove a product can prevent stretch marks during pregnancy.
The Mederma cream was the only one tested as formulated and the extract, centella asiactica, was also evaluated in a clinical trial and shows promise in preventing or reducing stretch marks.
Centella Asiatica, present in the Mederma and Palmer's products, appears to be able to increase skin fibroblasts collagen production, according to clinical studies.
- In a study published in the International Journal of Cosmetics Science, another unidentified product containing centella asiatica, hydrolyzed collagen and elastin and vitamin was tested, and 89% of the women who used the cream during pregnancy did not get stretch marks whereas all the untreated women did.
- In addition, in a review article of stretch mark creams in the Cochrane Database of Systematic Reviews in 2000, only the cream with the centella asiatica extract was found to be effective for reducing stretch marks.
It is likely that existing stretch marks improve slowly over time without treatment beyond keeping your skin moisturized. Though they will fade, most are unlikely to disappear, however.
Although a cream may prove to be able to reduce the appearance of stretch marks, no current product or ingredient has been proven capable of repairing damaged elastin or collagen fibers, which is the cause of stretch marks.
