NewGel vs Mederma

Do you need help deciding between NewGel+ and Mederma for your scars?

Lucky for you, I’ve put together a full comparison of NewGel vs Mederma.

NewGel+ is an excellent silicone gel while Mederma is a popular onion extract gel.

You’re probably wondering, “So which one is better?”

Well…

The short version is: NewGel+.

You see, onion extract gels like Mederma are promising, but not yet supported by the medical community for scar treatment due to mixed clinical evidence. (1)

Silicone gels, on the other hand, are backed by decades of clinical research and recommended for hypertrophic scars and keloids by both dermatologists and plastic surgeons.

My top pick for a silicone gel is NewGel+ (I use this one myself).

Our Recommendations

NewGel+ is an excellent silicone gel that is available at a reasonable price.

Silicone gels are clinically proven to reduce scars.

They are recommended by the International Advisory Panel on Scar Management for both hypertrophic scars and keloids. (1)

Unlike other scar products, silicone gels are lightweight, odorless, and do not cause side effects like itchiness or skin discoloration (issues that I’ve found with Mederma).

Silicone gels are also easy to apply. 

To be fair, I’ve had some success with Mederma before for my chest keloids (see here).

But after 6 months, I stopped using Mederma due to side effects like itchiness and skin discoloration. I’ve since switched to NewGel+ and haven’t experienced any side effects.

To Wrap Up:

If you want the best results for your scars, stick with a silicone gel like NewGel+.

If you have less severe scars or are on a tight budget, Mederma is a great option.

NewGel+ Advanced Silicone Gel for Scars

Our Score: 5/5

My top pick for a silicone gel. Effective & affordable with outstanding reviews.

PROS

  • Reduces scar height & size
  • Restores normal skin color
  • Easy to apply
  • Outstanding reviews
  • Reasonably priced

CONS

  • Results require patience
  • Product may leak out if you’re not careful (like me)

NewGel+ is an excellent option for many types of scars, including hypertrophic scars, keloids, surgical scars (such as C-section), and scars from trauma, burns, or injuries.

The ingredients are simple:

  • Polymerized Siloxanes: Silicone Gel
  • 0.5% Tocopherol: Vitamin E

Silicone is clinically proven to improve scar appearance and skin discoloration. (1)

It works by keeping your skin hydrated, which in turn prevents collagen production, a major contributor to hypertrophic scar and keloid formation. 

Vitamin E is also included to help moisturize and soften scars. As a bonus, vitamin E is a powerful antioxidant that can protect your skin from harmful UV rays.

NewGel+ has a thin and smooth texture, making it easy to apply and leave on your skin throughout the day. 

Key Features

  • Medical grade silicone gel
  • Vitamin E
  • Thin and smooth texture
  • Fast drying

Key Benefits

  • Flattens existing scars
  • Prevents new scars
  • Reduces skin discoloration
  • Lightweight and easy to apply
  • Reasonably priced

Suitable For

  • Hypertrophic scars
  • Keloids (including on the chest or earlobes)
  • Surgical scars (including C-section)
  • Scars from trauma, burns, or injuries
  • Scars on the face, hands, and other visible areas

Why Silicone?

Silicone is the #1 dermatologist and plastic surgeon recommended over-the-counter scar reduction ingredient, according to an independent market research firm. (2)

In 2014, the International Advisory Panel on Scar Management confirmed the clinical efficacy of silicone for the treatment of hypertrophic scars and keloids. (1)

Researchers believe that silicone works by hydrating and protecting the scar. This prevents skin dehydration which can contribute to abnormal scar formation. (3)

NewGel Reviews

Among the positive reviews, many people claimed NewGel+ reduced their scar appearance, including scar size, scar height, and skin discoloration.

Among the negative reviews, some people didn’t see any results with their scars or had issues with the packaging (the tube can leak out if you press too hard).

I find that most people don’t use silicone gels long enough to see the desired results. In my experience, it takes between 3-6 months before you’ll notice any significant improvements. 

As with all skincare products, your mileage may vary (YMMV).

The Bottom-Line

NewGel+ is my top pick for a silicone gel. It’s effective, easy to apply, and reasonably priced.

Mederma Advanced Scar Gel

PROS

  • Softens existing scars
  • Reduces discoloration
  • Thousands of reviews
  • Affordable

CONS

  • Inconclusive clinical studies
  • Results require patience
  • May cause itchiness, irritation, or redness

About Mederma

If you want great results that won’t break the bank, Mederma is an excellent option.

Featuring Cepalin (onion extract), Mederma has been the #1 pharmacist recommended brand for 15 years.

Although clinical studies of onion extract are somewhat mixed, it’s clear that Mederma has helped thousands of people with their scar problems.

Amazon alone has well over 2,000 reviews, including hundreds of before/after photos.

Personally, I’ve used Mederma for my chest keloids and have seen slow but steady improvements in scar texture and color (check out my progress photos here).

Mederma has a light texture and mild scent. It’s easy to apply and dries quickly.

Key Features

  • Cepalin (onion extract)
  • Light texture
  • Mild scent
  • Dries quickly

Key Benefits

  • Softens existing scars
  • Reduces scar discoloration
  • Won’t break the bank

Suitable For

  • Hypertrophic scars
  • Keloids (including on the chest or earlobes)
  • Surgical scars (including C-section)
  • Scars from trauma, burns, or injuries
  • Scars on the face, hands, and other visible areas

Why Onion Extract?

Onion extract (allium cepa) has antioxidant and anti-inflammatory properties.

Studies show that onion extract may inhibit fibroblasts (cells that produce collagen). (3) 

This can help soften hypertrophic scars and keloids and may also reduce discoloration. 

Onion extract also contains quercetin, a plant flavonoid that inhibits collagen. (4)

The clinical evidence, however, is still inconclusive:

  • One study reported no difference between onion extract and Vaseline (5)
  • Other studies reported positive results using onion extract (6, 7, 8)
  • One study was funded by Merz (manufacturer of Mederma) (8)

Why Mederma?

In my opinion, the main selling point of Mederma is the price.

It’s more affordable than alternative scar treatments like silicone gels and corticosteroid injections, both of which are used for hypertrophic scars and keloids. 

Mederma is also widely available at retailers like Wal-Mart and online at Amazon.

As for the product itself, it definitely works (see my progress photos here). 

But it requires a lot of patience and most people quit too early. In my experience, it takes at least 3 months before you’ll see any noticeable results.

Mederma Reviews

Mederma has well over 2,000 reviews on Amazon. While reviews are mostly positive, Mederma doesn’t work for everyone. 

For some people, Mederma flattened their scars completely. But for others, it didn’t seem to move the needle much.

As with all skincare products, your mileage may vary (YMMV).

Side effects of Mederma may include itchiness, irritation, and redness. 

Read my full review of Mederma here.

Pro Tip: use Mederma 2x daily (instead of 1x) to maintain continuous scar coverage.

The Bottom-Line

Mederma is a popular scar gel that works well and is quite affordable.

What Causes Scars?

Ever wonder why you get those pesky scars in the first place?

Well, research suggests that genetics are partly to blame (thanks, Mom and Dad). (9)

But scars themselves are a natural response by your body to injuries.

Part 1: Inflammation

When you’re injured, your body sets off an “alarm” signal known as inflammation.

This process jumpstarts the immune system and triggers wound healing signals.

Part 2: Repair

After inflammation comes the repair stage.

Your body replaces damaged skin with new skin cells and materials like collagen.

Collagen fibers weave together to form the foundations of new skin tissue (a “scar”).

Part 3: Scars

Unfortunately, scars are seldom identical to the original skin.

They’re often a different color and may feel hard or lumpy.

Sometimes, scars end up elevated like hypertrophic scars or keloids. 

This happens if your body produced too much collagen during the repair stage.

The Bottom-Line

I hope this guide to Mederma vs NewGel helps you pick the right product for you. 

Remember, nothing can replace patience and consistency! 

To Recap:

If you want the best results, go for a silicone gel like NewGel+.

If you’re on a limited budget, a good alternative is Mederma.
