In over 20 countries, Mederma is the number one selling remedy for stretch marks used by both women and men. The maker of the product proudly states that their clinical trial showed that 80 percent of users of Mederma saw visible results in 12 weeks or less, and that using the cream regularly smoothed lines, lightened pigmentation, and enhanced flexibility of the skin.

Does Mederma Work on Stretch Marks?

Mederma is made from a well-known Ayurvedic herb called Gotu kola, sometimes known by its botanical name, Centella Asiatica.

It contains hyaluronic acid, the basic building material for membranes throughout the human body, and a propriety formula based on onion skin the company calls cepalin.

Gotu kola appears in numerous products for stretch marks, scars, and cellulite. Several dozen scientific studies show that it stimulates fibroblasts in the skin to produce collagen between skin cells.

There are some very important advantages to using Gotu kola to stimulate collagen to treat stretch marks.

The first and foremost benefit of using collagen is that stretch marks are places the skin needs to “fill in” to smooth out. Stretch marks occur when the skin simply cannot grow fast enough to keep up with the muscle tissue growing beneath it. Additional collagen production helps the skin stretch to cover the muscle layer.

The second benefit to using Gotu kola is that it generates collagen in the skin, rather than on the skin.

Many expensive products list collagen as an ingredient in their creams or lotions.

The collagen in these products cannot penetrate the skin. It’s simply too bulky to travel through a pore.

The collagen in the product combines with moisture in perspiration to cover up the stretch mark, but the first time the skin is washed, the collagen is washed away.

Gotu kola stimulates the skin’s own production of collagen for a lasting effect.

Of course, collagen can be injected into the skin. But do you really want to have collagen collected from human cadavers, aborted fetuses, or animal feet injected into your body? Gotu kola is much more natural and far less expensive.

Hyaluronic acid is a naturally occurring chemical the body makes to give membranes and skin their “stretch.” It incorporates water into the skin to make it more flexible. Hyaluronic acid is usually identified as a “natural moisturizing factor” or NMF.

The Real Role of Cepalin – Mederma’s Active Ingredient

The controversial ingredient in Mederma is cepalin. Many critics of Mederma, almost all of whom are trying to sell you another formula, argue that since there is not a paper trail of scientific evidence for cepalin, the product must not work.

The simple fact is, cepalin probably does enhance the value of the formula, but most of the beneficial effects of the product are due to Gotu kola and hyaluronic acid.

In the cosmetics trade, formulas are usually patented. A patent cannot be granted unless the formula is different from other products in a distinctive way.

Usually, this means that the manufacturer adds a unique, proprietary ingredient that other companies cannot easily duplicate. Then the patent protects the maker of a good product from spending millions of dollars, defending claims that some other company really invented their product.

What are People Saying?

In order to give you the most complete review of this product possible, we scoured through both good and bad customer reviews, and here’s what people are generally saying about the Mederma Stretch Mark Cream:


  • We found several very convincing Before and After pictures;
  • Evened out the tone of the skin;
  • Fades stretch marks considerably;
  • Smells nice, not too strong;
  • Paraben-free, mineral-free, fragrance-free;
  • Minimized stretch marks;
  • Safe to use during pregnancy;
  • Very moisturizing, so also good if you’re trying to prevent the appearance of stretch marks.


  • Does take time for it to work, so expect to use this for quite a few weeks (it’s not some overnight, miracle cure);
  • Quite expensive;
  • Some couldn’t tolerate the smell;
  • Might not be as effective for older stretch marks as it is for new ones;
  • The container is quite small.

Overall, we’d say the good reviews far outweighed the bad, and so in our own Mederma review for stretch marks, this cream passes with flying colors, since most of the users were quite happy with its effect on their scars.

User’s Q&A: Your Hottest Questions Answered!

We’re all familiar with the excitement and curiosity stage of discovering a new product that may or may not be the answer to all your skincare prayers. So, we’ve compiled all the most frequently asked Mederma questions here, for your convenience.

  • How long does it usually take to see results with Mederma?

    According to a survey conducted by Mederma, 76% of women who used Mederma Stretch Mark Therapy for 12 weeks saw a great improvement in the appearance of their stretch marks.

    And while we read some reviews that mentioned seeing a difference in as little as four weeks, we would encourage you to use it for at least three months to reap the full benefits.

  • Can I use it while pregnant/breastfeeding?

    Of course, you can. Mederma was specially designed for the treatment of stretch marks, so the manufacturer did consider the possibility of it being used during pregnancy and made sure it was safe.

  • How effective is Mederma for old (white) stretch marks?

    We’ll be honest with you, no stretch mark cream can be as effective for old marks as it is for fresh ones. However, several customers noted an improvement even in their old, faded stretch marks, in that Mederma reduced the appearance of the stretch marks and evened out the skin tone around them.

    So as far as these creams go, we’d say Mederma is quite effective both for new, red stretch marks and older, white ones.

  • Will results go away if I stop using it?

    No, they will not. Although if you stop using moisturizers entirely, do expect your skin to get drier and worse-looking. Stretch marks might also appear worse in dry skin, which is why some people think results have gone away. But the worsened appearance is actually the result of less moisture and dwindling collagen production in the skin.

  • Is there a Mederma Stretch Mark Lotion as well?

    Alas, no, there is not. Therapy is a cream, and as such, its consistency is a little heavier than your run-of-the-mill lotion (though not as heavy as a body butter). There is another product called Quick Dry Oil but there are no Mederma lotions at the time of this writing.

  • Can I use the Mederma Advanced Scar Gel on my stretch marks?

    Technically, yes, although bear in mind that it was not formulated to treat stretch marks. It might improve the appearance of your stretch marks, or it might not, but for best effects, Mederma recommends sticking to the products that are specially designed for your specific condition.

  • Will it get rid of my stretch marks completely?

    According to what people are saying, no, it will not. What this cream will do is considerably fade and improve the appearance of your stretch marks. But if you expect your marks to disappear completely, then you might be disappointed.

  • How should I use the Mederma cream for the best results?

    It’s recommended that you use Mederma cream twice a day, in the morning and evening, and that you massage it well into the skin to ensure absorption. It’s also encouraged that you apply it after a warm shower, which can open the pores.

  • Can I use Mederma to prevent stretch marks?

    Stretch marks are largely inherited and, as such, can not be prevented. What you can do, however, is to moisturize your skin, to help it accommodate the stretching. This can result in your stretch marks appearing less deep or less intense, but it won’t prevent them altogether.

Are There Any Other Products for Stretch Marks?

Yes, as it happens, Mederma also offers a Quick Dry Oil for stretch marks and other scars, which is also Cepalin-based.

The Quick Dry Oil consists of a wide variety of oils, such as coconut, apricot, sweet almond, and sunflower seed oil. All of these are well-known for their hydrating properties, as well as their ability to boost collagen production and speed up the healing process.

Besides Cepalin, the Mederma cream and the oil have Onion Bulb Extract in common, as an ingredient. Onion extract is a well known at-home remedy for scars. It has been shown to reduce both the appearance and the redness of the scar. It can also improve texture, with many people noting that their scarred skin felt much softer after using onion extract.

The only real difference, as far as ingredients are concerned, is that the Mederma Quick Dry Oil does not include Centella Asiatica extract, which is a shame, but it does have more than plenty of other ingredients that compensate the loss.

As with the Mederma Stretch Mark Cream, customers seemed to be overall happy with the Quik Dry Oil. Of course, some said it did not work for them, but as far as we can tell, the good stuff far outweighed the bad.

At the time of this writing, Amazon was having an impressive 60% off sale on Mederma Stretch Mark Therapy, which put the two products in a similar price range. It’s a great opportunity to purchase them together and use them as a duo.

What’s the Difference Between Stretch Mark Therapy and Quick Dry Oil?

Other than the different ingredients, the main difference between the two products lies in their consistency. See, the cream is more easily absorbed into the skin, which is why a lot of people prefer it. The oil, while more hydrating, is also more difficult to absorb into the skin, and you run the risk of it getting on your clothes.

Now, that’s the difference between most hydrating creams and oils, but Mederma sets out to balance it out.

With the ‘quick dry‘ effect, the oil can be easily used and won’t take forever to absorb into the skin. However, that doesn’t mean the oil will fade away completely, but rather dry (as the name tells us) on your skin, thus permitting you to go about your business without worrying about the oil staining furniture or clothes.

As far as effect is concerned;

  • Mederma Stretch Mark Therapy seems to be more heavily focused on the healing aspect of the process
  • Whereas the Quick Dry Oil contains more deeply-hydrating ingredients.

That is why we think it’d be a good idea to use both in tandem so that you get to reap effects from both.

Mederma Vs. Bio-Oil – What’s the Difference And Which Is Better?

Quick Dry Oil Absorption Rate

We don’t like calling one product better than the other, because we believe that each person is different, and so what works great for one might not work great for another.

Both the Mederma Quick Dry Oil and Bio-Oil have gotten great reviews over the years, and each has amassed a loyal following.

While they share several ingredients, Quick Dry Oil seems to be more nature-oriented. It contains a lot of more natural extracts and oils than the Bio-Oil, interestingly enough.

That is not to say that Bio-Oil is without merit, however. Bio-Oil has Lavender Oil, for example, which has been shown to have great wound-healing propertiesand accelerate the skin’s process of rebuilding damaged cells.

However, one thing that we cannot like about Bio-Oil is that it contains liquid paraffin, a petroleum-derivate commonly used for candles and cosmetic products. Over the years, several dermatologists have warned against the use of paraffin, claiming it has negative effects on the body both when inhaled and when applied to the skin.

At the very least, it clogs to pores, and it has been linked with asthma and cancer, so not something we’d want to put on our bodies, especially when pregnant.

But other than that, both products have proven potent and effective over the years, and considering they’re both in the same price range, they might both be viable options.

Buying Options

Wondering where you can purchase Mederma? All the Mederma products are available through Amazon, where they’re being sold by Mederma themselves, so you don’t have to worry about getting a fake.

If you’d prefer purchasing Mederma in-store, know that the Mederma products are available at a wide array of shops, such as Walmart, Target, CVS Pharmacy, RiteAid, and Walgreens.

Are there any coupons/offers you should know about?

While Mederma does offer coupons for various products, at the time of this writing, none were available. However, we would encourage you to check before purchasing, ’cause you might be in luck!

What happens if I’m not happy? Can I get my money back?

Yes, Mederma has a very interesting money back policy. It states that if you’re not happy with the product after using it consistently for 3 months, you can print out a form (available on their website) and send it to them together with the receipt of the product, for a full refund.

In the end…

The simple truth about Mederma stretch mark therapy is that it works.

Considering that the vendor is offering a money-back guarantee, it seems you have nothing to lose but your stretch marks.
