Treating my scars just makes me want to cry. But not that I am sad about them, it's because Mederma contains Allium Cepa (AKA the common onion).

That's right, the ingredient actually treating your scars in Mederma is onion, although they don't list it as an active ingredient. Keep scrolling because below we have many REAL Mederma before and after results so you can be sure if it works or not.

There’s a lot of hope alongside the hype involved when we hear about a new scar treatment and over the years there have been plenty of products that promise to help you. However, after several tries with different treatments, it can be easy to lose hope.Of course, you shouldn’t expect miracles from any of these products. A scar is referred to as a “permanent” issue for a reason.

 However, there are products available that will help to improve the appearance of your scars over time.With this in mind, we are going to take a long, hard look at Mederma Advanced Scar Gel. Before you get your hopes up or your wallet open, we are going to look into what Maderma is, how it works, and if users actually got anything out of it. By the end of this article, you will be able to make a well-informed decision.

What Types of Scars are There? + Mederma Before and After Pics

Before we get into how to treat your scars with Mederma, it is only fair that we discuss the different types of scars as these will come up in our discussion of Mederma Advanced Scar Gel. Scars can, of course, be different depending on their size, location, and age. Generally, though, scars are classified as either atrophic scars or keloid and hypertrophic scars.

Atrophic scars are the scars that sink in and form a depression in your skin. They sink in due to the damage that the original injury caused fat, collagen, and tissues below the skin’s surface. These are usually caused by acne, chicken pox, surgery, and other common accidents.

Keloid and hypertrophic scars are harder to get rid of as neither will go away on their own. Both these are raised scars that are harder to get rid of than atrophic scars. They are caused by too many cells grow over the injury as it tries to heal. See the below Mederma before and after images:

The major difference between keloid and hypertrophic scars is that keloid scars are what most of us would simply describe as worse. Rather than just raising above the old wounds, keloid scars tend to grow out slightly beyond the site of the original injury causing a red or purple, raised scar to form. Certain ethnicities have shown a higher likelihood of producing extra collagen and causing these types of scars, including those of African-American, Hispanic, and Asian descent.

Unfortunately, these raised and “angry” scars are harder to get rid of because instead of new skin forming over them, they have to be smoothed. While some people opt to get surgery for these, they are generally stubborn and tend to come back. In addition, surgery or chemical peels can be painful and expensive. So, finding a scar gel that can help keloid and hypertrophic scars is fantastic.

How Can You Prevent Scars?

Again, before we get into a specific product to care for scars let’s take a look at how you can avoid them altogether. Of course, the first tip is to be careful with your skin. If you are predisposed to skin conditions such as acne, it is probably best to try and take careful care of your skin and treat the issue affecting your skin.

When you injure yourself, make sure to take proper care of the injury. If it is an injury bad enough to land you in a doctor’s office, you can usually ask them for tips on how to make sure it heals with the least amount of lasting impact on your skin as possible. Definitely do not pick scabs, acne, or injuries to avoid scarring.

The best advice that we can give is just to take care of your skin. The healthier your skin is, the less likely it is to break out or react poorly when you do get an injury. In addition, it is important to know your skin. If you are predisposed to scarring, you can ask your dermatologist or doctor for advice as injuries occur and before.

It can also be said that a good scar gel will help to prevent future scarring. If you use a scar gel daily - as most call for - and it does its job, your skin will have improved elasticity and be moisturized. Qualities such as this help your skin to heal properly as new injuries occur.

Common Treatments for Scars

As a basis for comparison, let’s take a look at some common measures taken to prevent scarring. Not only does this help you to understand ways to treat and lessen your scars but some of these methods will reemerge as we analyze how Mederma works.

While the injury is new, antibacterial cream and a bandage is the most common treatment. As we mentioned before, there are other treatment routes that you can be consulted on but the best way to treat a scar is to do your best to prevent their development.

As we will discuss with Mederma, scar gels are another excellent way to fade your scars out. They often use the active ingredient allantoin to help smooth and heal scar tissue. We will discuss the exact uses and doses of this ingredient later on.

Silicone sheets and gels can be used as well. These are best used as a scar is starting to form to lessen the amount of scar tissue can be formed. Onion extract can be used as well to reduce the redness / discoloration in a scar. It will also improve the texture of your scars, helping to keep them from getting too deep or building up too much.

You should also be sure to use sunscreen on your scars. This probably isn’t surprising, since protecting your skin can save you from a wide variety of skin problems. In this case, though, it can protect you from excessive darkening of your scars.

For deeper scars and stretch marks, in-office cosmetic options have been evolving over the years. Some of these are laser surgeries, chemical peels, physical therapy, steroid injections and more. If you are in need of a more intensive treatment such as this, though, you should talk to your doctor or specialist to find out if it is right for you.

Who is Mederma?

Before we get into what Mederma has to offer or what customers think, it is important to understand who Maderma is as a company. The Mederma line is actually a product of a company called Merz North America which operates in Canada and the United States. They offer over 100 years of experience to their customers who put a lot of faith in their products.

Merz North America is a specialty healthcare company. Their specialties lie in aesthetics, dermatology, and neuroscience. They are determined to make sure that their customers are confident and have help with any cosmetic and aesthetic issues or movement disorders. They promise that Mederma can be used to give scars a “softer, smoother, and less noticeable” appearance.

However, Merz wasn’t always Merz North America. It actually began in Frankfurt, Germany in 1908 as Merz Pharma Group. At the time, they focused on pharmaceuticals to treat mental illness and neurological disorders. Since then, they have developed on these topics as well as added their dermatologic and aesthetic products and lines. Though they conduct their business in the United States and Canada now, they do still have a privately owned headquarters in Frankfurt, Germany.

What is Mederma Advanced Scar Gel?

The Mederma Advanced Scar Gel is a topical option that you use once a day. According to Mederma, the scar gel they’ve developed is the “first and ONLY daily topical scar gel”. This scar gel is impressive because it is one of the most recommended products by both doctors and pharmacists. This is more than just a weak marketing promise, though, as both the Journal of Clinical and Aesthetic Dermatology as well as the Pharmacy Times and U.S. News & World Report back it up with research.

Mederma Advanced Scar Gel promises to reduce the appearance of your scars with daily use. It promises to act as an effective treatment for both old and new scars including burns, acne scars, surgery scars, as well as cuts and other various injuries. It is important to note the wording here; Mederma Scar Gel promises to fade the appearance of scars, not get rid of them entirely.

What is in Mederma Scar Gel?

One thing that is important to know is what is in anything that you are using on your body. This is, in part, important to know because if you have any allergies, you can look at these ingredients to prevent a reaction before it happens.

In addition, it is just generally a good idea to know what you are putting on your skin. If you look at the back of many bottles, you are probably greeted with a litany of long, chemical names that you don’t recognize. If you don’t even know how to pronounce these ingredients, though, you likely don’t know what they are doing to your skin. So, let’s take a look at the ingredients of Mederma Advanced Scar Gel and then we can look at what they mean.

  • Allantoin 0.5% (Active Ingredient)
  • Purified Water
  • PEG 200
  • Alcohol
  • Xanthan Gum
  • Allium Cepa (Onion) Bulb Extract
  • Lecithin
  • Methylparaben
  • Sorbic Acid
  • Panthenol
  • Sodium Hyaluronate
  • Fragrance

This is rather simple formula - which is good. Without extra chemicals, compounds, and ingredients you are far less likely to have an adverse reaction to using the Mederma Advanced Scar Gel.

First, let’s look at the active ingredient. Allantoin is a common ingredient for scar treatment as it smooths and softens scars. To be more specific, it softens the protein (keratin) that makes your skin tough while removing dead skin cells at the same time. This promotion of skin renewal, though, is partially related to the concentration of the dosage. 0.5% is the lowest dosage that most companies use with 2% being the highest. So, that leaves Mederma a little low on the dosage of Allantoin they use.

Lecithin is an ingredient that will help to keep your skin moisturized. This is important because when a scar is forming over a wound, that part of the skin is usually deprived of moisture, making it difficult for the skin to heal without leaving a mark. Lecithin will form a barrier over the skin to help keep your skin moisturized by preventing water evaporation. More Mederma before and after pictures below:

Methylparaben and sorbic acid are so similar, it is easier to look at them together. Both are used for the same purpose; to keep mold and bugs out of the tube of scar gel. Sorbic acid doesn’t have any real fears attached to it - it just exists. Methylparaben, on the other hand, is a harder subject. Many fear that it could cause cancer due to some of the molecules it creates, but mostly it will just make your skin sensitive to the sun. If you have to go into the sun, make sure to protect your skin.

Panthenol is added, but pantothenic acid (vitamin B5) is already produced by Mederma’s most important ingredient, cepalin, which we will discuss later. Panthenol, though, has the same basic purpose as the alcohol. It keeps your skin elastic by helping to promote healing - an important feature in healing without scars.

Sodium Hyaluronate is a trap that will keep the moisture in your skin. This is also a preemptive measure for your skin. Since it helps to keep your skin moisturized, it will also prevent the likelihood of new injuries resulting in bad scarring.

Mederma’s Important Ingredient: What is Cepalin?

You may have noticed that we left an ingredient out. This is because the allium cepa bulb extract is such a key ingredient to the Mederma Advanced Scar Treatment, we thought that we should go over it at length rather than just grace over its basic properties.

mederma before and after

Mederma Before and After #7

The generic name for this Mederma’s scar gel is cepalin. This is thanks to one of the most crucial ingredients in the formula: allium cepa bulb extract. As you may have noticed in the parenthesis above, this is a natural ingredient that can be more simply put as onion bulb extract.

This ingredient is used to treat inflammation and swelling - which is important when considering hypertrophic and keloid scars especially. If you use Mederma Advanced Scar Gel regularly, the cepalin in it can help to prevent the development of future scars.

On the other hand, it is important to consider if cepalin is something that works. After all, it isn’t like every scar treatment on the market uses this ingredient. Well, in studies that Mederma held, those who you used this every day for 8 weeks on your scar found around a 36% improvement.

On the other hand, there aren’t many studies to show the help of cepalin alone. It is an old remedy, so there are plenty of people who would swear by it. However, there isn’t much hard data to say that the cepalin is what really makes the difference in Mederma like it says.

Who Should Use Mederma Advanced Scar Gel, Mederma Before and After Results

One of the best things about Mederma’s products is that nearly anyone with a scar can use them. If you have sensitive skin, though, you may react to some of the ingredients. On the off chance that you do experience these reactions, stop using this immediately.

If you are looking for a scar treatment for your child, though, you could try Mederma Advanced Scar Gel but we don’t necessarily recommend it. This is because Mederma has created specific products for children and these are more likely to be safe on their skin and not cause a reaction.

If Mederma Advanced Scar Gel treatment doesn’t cause their skin to have an adverse reaction, there isn’t anything in there that will hurt them.

Mederma Advanced Scar Gel Recommended Use

Mederma offers a rather simple regimen for use with their scar gel. As they advertised, you should only have to use it once a day to get effective results. When you apply it, you should use it sparingly. Overusing the gel won’t increase its effectiveness. You should message a thin layer of the scar gel into your skin until it completely absorbs. There should be no film, grease, or shine left on your skin once you apply it.

It is also a good idea to clean the area of application before applying the Maderma scar gel. This will allow the scar gel to absorb into your skin easier. Your best option is to use a mild soap and water to cleanse it but if this doesn’t help, you might be using too much of the Maderma scar gel.

So, when should you start using Mederma? You can start - at the earliest - generally, two weeks after an injury or surgery. If the skin is still broken and the wound is open, though, do not use Mederma Advanced Scar Gel treatment yet. If your scars are older, however, you can start immediately as there is no risk of interfering with the healing process.

On average, Mederma says that four weeks of daily use should start to show some signs of healing. However, new scars usually take 8 weeks to work on new scars and 3 to 6 months on older scars. Remember, though, this must be used daily to achieve results ; using Maderma once in awhile probably won’t show the results you are looking for.

Does Mederma Advanced Scar Gel Have Any Side Effects?

No, Mederma scar gel does not have any notable negative side effects for most people. Although, some users do have trouble with allergic reactions, this is rare and doesn’t happen often. Just in case, though, both the developers of this product and doctors recommend that you do a skin test. For this, just add a small dollop on the back of your hand, for example. Rub it in like you normally would and wait. If no reaction happens in the next couple hours, odds are you won’t have a reaction.

If you are planning to use this product on your face, it is better to test it on skin that is like that of your face. The best choice for this is to test Mederma Advanced Scar Gel somewhere on your jawline. The skin here is softer and more delicate and while the test on the back of your hand may help to discover any allergies, this test on your jawline will help to predict if it will cause any acne or breakouts on with use on your face.

Can You Use Mederma Advanced Scar Gel On Your Face?

Merz North America made Mederma Advanced Scar Gel to help with all kinds of scarring - acne scars included. However, it is important with any product to make sure that it is safe for facial use before doing so since the skin on your face can be so much more sensitive.

Luckily, Mederma Advanced Scar Gel is more than just safe for your face. It is also non-greasy and water-based, so you won’t have to deal with acne breakouts while you try to fade old scars out.

Can You Use Mederma with Other Skin Care Products?

The short answer to this question is yes. You can in fact use Mederma with any of your lotions, makeup, or other cosmetics without worrying about a reaction. However, Mederma Advanced Scar Gel does need to absorb into the skin, so applying it to clean skin is best.


Mederma Advanced Scar Gel Warnings

We have already gone over the main warning of Mederma Advanced Scar Gel - do not use it on broken skin and open wounds. This is a product that is made for external use only. If you get into a cut or open wound will slow the healing process and possibly even cause further complications. In a similar strain, you should also avoid getting this in and around your eyes.

If you find you have any allergic reactions to this product, you should cease use immediately and seek treatment for any severe reactions. If it irritates the scar that you are treating and it continues or worsens over 7 days, you should ask a doctor about it.

As with any other product you use, it is recommended that you keep this out of reach of any children. It is not meant to be ingested and if it is, you should contact Poison Control or a doctor right away. On this topic, you should also flush your eyes immediately if it gets in them to prevent both pain and damage.

Does Mederma Work?

Many customers did find that Mederma Advanced Scar Gel was a good fit for them. However, they also said it took longer than they were promised and that it only worked on old scars. For an old scar to fade, many customers reported that it took at least six months to see significant results when Mederma promised a difference to show at the 8 week mark.

For those who have the time, patience, and old enough scar, though, Mederma scar gel will help it to fade. If you have a newer scar, it may help but most customers said it took too long for them to wait for results.

Does Mederma Get Rid of Scars Completely?

Mederma is for scar treatment. Take note that they do not advertise themselves as scar removal. We touched on this before, but let’s expand on the idea just to be clear.

Scars are, by their nature, permanent. As such, there aren’t many treatments that can completely remove them and no gels can completely erase them - Mederma Advanced Scar Gel included.

However, Mederma can be used to fade the appearance of scars. While it isn’t a perfect solution, the fading of scars is an easier solution to achieve and it still makes them far less noticeable. Even if they aren’t gone, you can still improve their appearance and feel better about how you look.

Is Mederma Expensive?

Unfortunately, Mederma Advanced Scar treatment can be rather expensive. While it isn’t at an unattainable price, you are going to have to be ready to spend a little extra cash for your bottle. In the end, though, most scar treatments are going to run you a bit of a bill and Mederma is far from the worst.

Where Can You Buy Mederma Scar Gel?

If you are purchasing a scar gel, it can be annoying if you have to hunt down a bottle or jump through hoops to get it. Luckily, Mederma is rather easy to get your hands on. You can, of course, purchase it on the Mederma website but they have branched into retail beyond that. If you would like to stay online, though, Amazon is a trusted online retailer that Maderma works with.

However, you can also get this product from plenty of off-line retailers if you would prefer to pick up a bottle of Mederma while you run errands. The featured retailers that Mederma works with are also large, commonly found companies. You can purchase Mederma at the following locations;

  • CVS Pharmacy
  • Rite Aid
  • Target
  • Walgreens
  • Walmart

Mederma Reviews: The Good

Many customers did have good things to say about Mederma Advanced Scar Gel. Those with older scars said that after around 6 months of use they noticed a significant difference in how their scars looked. It is even safe for use on the face and many people finally got to say goodbye to old acne scars.

Mederma is also generally safe for everyone to use. Thanks to their short ingredient list, there is less of a chance for potential negative interactions or for there to be an ingredient that you are allergic to. So, it is generally a product that you can rely on for your scars.

On a more superficial side, this product doesn’t smell bad. So, even if you are self-conscious about your scars and using Mederma Advanced Scar Gel, no one will be able to tell you are. If you aren’t, though, you still won’t have to deal with a medicinal or bad smell while you use it.

Mederma Reviews: The Bad

However, Mederma doesn’t quite live up to all their promises. The biggest disappointment is how Mederma works on new scars. Even though they promise that a result will show if you continue to use the product every day, it still takes long enough that by the time you see some change, the scar is an old scar.

Unfortunately, Mederma does take longer than it promises to work on most scars. While it does work, don’t expect much of a difference at the eight week mark that Mederma promises. Rather, you should expect a difference closer to six months.

Another complaint is that it's pretty expensive. While you aren’t going to clear out your bank account, don’t expect to pick it up at the same price you pick up your lotion. Fortunately, though, it isn’t the most expensive scar treatment that you can buy either. Mederma before and after pictures:

What if Mederma Scar Gel Doesn’t Work for You?

After looking at some of the complaints, it is only fair to acknowledge that not everyone will be happy with the Mederma scar gel. If you give it the full, suggested time period for your scars and still see no results, Mederma has a form on their website that you can fill out and send to them alongside the receipt of purchase.

They will refund the purchase price without any extra fees and taxes that may have been added on. However, if you experience an allergic reaction, you - of course - won’t have to use it for the full suggested time period before trying in these instances.

If you have further questions, though, Mederma asks customers to direct them to 1-855-925-8989.

When you are considering Mederma Advanced Scar Gel versus their competitors, it brings us back to cepalin. This ingredient isn’t used very much in other scar treatments today since it doesn’t have many scientific studies to back it up or disprove it.

This makes it different because most treatments have a main and singular goal of getting rid of and fading scars.

Conclusion: Is Mederma Advanced Scar Gel Worth Your Time and Money?

When it comes down to it, though, is Mederma Advanced Scar Gel worth it? We think so! Yes, it has its drawbacks but in the end they aren’t insurmountable and no product is perfect. It more than makes up for it, though. With a simple formula, it will help to treat your scars without damaging your skin.

In fact, this formula isn’t only less likely to cause an allergic reaction or damage, it actually works to nourish your skin to fade scars and prevent new ones. While it may take a while, if you stick with it you will see a definite improvement.
