In this article (Last Update 2018) we will explain to you what is Mederma, how does it work, what are its ingredients, side effects, show you real customer reviews, give you prices, best place to buy it & recommend best alternatives.

Mederma reviews aroused my curiosity because they seem so positive. I thought it was time I did a review of this scar cream to see what the truth was.

The bottom line here is that although your skin the can repair itself when it’s cut, abraised or torn, often scars are left behind forever.

As a scar forms, it creates inflammation. On top of that, as a scar heals, collagen may form in an irregular manner around the scar, creating an uneven surface and patterns. Often it can also cause a raised and hardened area. This is also true of stretch marks.

So dealing with scars and stretch marks is a complex process, especially when there are so many types, so what’s the truth about Mederma?

What Is Mederma?

The Mederma range targets scars and stretch marks through the following products:

  • Mederma Stretch Mark Therapy Cream
  • Mederma Intensive Overnight Scar Cream
  • Mederma Advanced Scar Gel
  • Mederma Scar Cream (SPF30)

There is often some confusion about the range of products because they do target different types of scarring, making people wonder which to use, something we will talk about later.

But generally, it falls into two groups, Mederma for stretch marks, and Mederma products for scarring.

There is another product, Mederma for kids. However that has exactly the same technical construction, the only difference being that it is a purple color initially and then dries clear.



The main active ingredient in Mederma is onion extract. This is not earth-shattering and many other skin products containing it as well.

A 2007 study did find that onion extract can reduce inflammation of the skin. In the short term, this can make fresh scars less noticeable.

It was also found that it could potentially shrink scars over time. This is because it was found to slightly inhibit the development of collagen, which is the cause of hardened and raised areas on scars. The second active ingredient is Allantoin 0.5% .

Within each product, there are other ingredients such as antioxidants, peptides and bizarrely collagen.

When I say bizarrely, it’s because the active ingredient is onion extract which claims to inhibit the development of collagen which can increase scarring.

Yet the intensive overnight scar cream, which is designed to work at night when allegedly the skin can regenerate itself more quickly, contains collagen.

That appears to me to be quite contradictory, feeding the scar something the active ingredient is minimizing?

So Does Mederma Really Work On All Scars?

To be clear, there are several distinct types of skin scarring, all with different causes and effects:

  • Keloids
  • Burn scars
  • Stretch marks
  • Acne scars
  • Cutting or abrasion scars

The bottom line here is that different scars form in different ways and have different structures.

All topical scar creams contain ingredients that claim to flatten scars and shrink them, such as onion extract, cortisone, silicone, and Vitamin E.

Generally each of these natural ingredients can affect scars in a minor way, but considering that people have to go through surgical scar treatment to get rid of even severe acne scars, and you can see how limited these products tend to be in terms of specifically targeting the scar.

Merderma acne scars lessening evidence is therefore going to require closer scrutiny by looking at what people say.

Mederma Cream Customer Reviews


A great place to look is Amazon, because there are so many verified purchases of any type of product.

Taking the Mederma advanced scar gel as an example product, it currently has 991 reviews on Amazon. Of those, 52% are five-star reviews. So generally the product is accepted positively:

“I am using 2 times a day about 2 weeks and my scar is better and lighter color now, hope it will get even lighter.”

However, my skepticism about how effective it is is echoed by this user review:

“It’s getting better but I’m not sure it’s because of this ointment or just it cures itself.”

And that’s the point here. Most user reviews are going to be very soon after the initial scar is formed, when the cut or abrasion is still healing. So obviously whether you use the cream or not the initial healing is going to be dramatic. This could be mistaken as from the cream, rather than just the body’s natural healing process.

This is borne out by the negative reviews such as:

“I have used this product as directed and have not seen any difference in the appearance of my scar. I was not expecting miracles but after 3 months, I expected to see a little difference in the shade of my scar. But, there has been no change. I will continue to use it until the tube is empty. If I find that there is some later change in the appearance of my scar, I will provide an update.”

So the truth is seems to be that although it has some minor effects, a lot of the initial enthusiasm around this product is because the body’s natural healing process is mistaken for Mederma.

Possible Side Effects

Some users report minor irritation using this product. However, this is usually reported as itching, which anyone who has had a scar knows can just be part of the healing process.

One possible concern is that Mederma pm for acne scars had a lot of users reporting irritation and reddened skin. As this is obviously going to be purchased by younger people with more sensitive skin, this could point to an issue with this product.

I would recommend that if you are going to use this as an acne treatment on a young person that you first speak to a doctor or dermatologist.

Final Verdict

I’m afraid it for me there is not a lot of evidence that Mederma will do a lot for you. Although it could help with very minor scarring and acne, many user reviews seem to suggest that you can use tube upon tube of this stuff and see no difference at all.

I cannot find any scientific studies which back up the claims made by the manufacturers, and generally I’m unconvinced that it has much of a positive effect on anything other than new scars which are going to heal anyway.
