If you’re looking for a Scar Zone review, you’re in the right place!
I’ve tried dozens of scar products over the years, including onion extract gels like Scar Zone. Essentially, this scar gel uses similar ingredients to Mederma at a fraction of the price.
In terms of scar treatment, clinical studies on onion extract are still inconclusive. (1)
I’ve used Mederma before with good results (see my full review here) but quite frankly I’d recommend that you buy a good quality silicone gel instead.
That’s because silicone is clinically proven to reduce the appearance of scars from surgery (including C-section), accidents, cuts & scrapes, burns, and even acne. (1)
My top recommendation for a silicone gel is NewGel+ (I use it myself). It’s an excellent scar gel with 100% silicone and vitamin E that balances effectiveness and affordability.

To Keep A Long Story Short...
Scar Zone is a value brand scar product by CCA Industries.
It’s essentially a close duplicate of the more popular Mederma Advanced Scar Gel, which features the key ingredient onion extract.
Clinical research into onion extract is not yet conclusive, which is why I recommend using silicone gels or sheets instead.
Silicone is clinically proven and recommended by the International Advisory Panel on Scar Management for hypertrophic scars and keloids.
My top pick for a silicone gel is NewGel+ (I use it myself).
On the other hand, onion extract gels like Mederma and Scar Zone are cheaper because they don’t use expensive medical grade silicone.
Right now, Scar Zone is about the same price (~$16 per oz) as Mederma (~$16 per oz) but cheaper than NewGel+ (~$40 per oz).
So at this point, I’d recommend Mederma over Scar Zone as I’ve had good personal experience with Mederma. But if you want the best results for your scars, I recommend using a silicone gel like NewGel+.
What is Scar Zone?
Scar Zone Advanced Scar Cream is an onion extract gel that works on hypertrophic scars, keloids, surgical scars (such as C-section), and scars from trauma, burns, or injuries.
It includes similar ingredients to Mederma but comes in a cream rather than a gel format. Creams offer extra hydration for those with drier skin while gels are better if you have oily skin or can’t stand the heaviness of a cream.
- Onion extract (same as Mederma)
- Sodium hyaluronate crosspolymer (hydrating)
- Hyaluronic acid (hydrating)
- Comes in 0.75 oz tube
- 1x daily application
- Flattens raised scars
- Reduces skin discoloration
- May prevent scars after surgery
- Thin, lightweight, easy to apply
- 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
How Does Scar Zone Work?
Onion extract (allium cepa) has antioxidant and anti-inflammatory properties.
Studies show that onion extract can inhibit fibroblasts (cells that produce collagen). This softens raised scars like hypertrophic scars and keloids and may reduce skin discoloration. (2)
Onion extract also contains quercetin, a plant flavonoid that inhibits collagen production. (3)
The clinical evidence, however, is not yet conclusive:
- One study reported no difference between onion extract and Vaseline (4)
- Other studies reported positive results with onion extract (5, 6, 7)
- One of these studies was funded by Merz (manufacturer of Mederma) (7)
Scar Zone Reviews
Among the positive reviews, people claimed Scar Zone reduced the appearance of their scars, including scar size, scar height, and skin redness.
Among the negative reviews, people noted that Scar Zone didn’t provide any benefits.
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).
"I LIKE THIS PRODUCT BECAUSE IN THE SHORT TIME I'VE USED ..."
"It works...even on old blemishes!"
Scar Zone is an affordable onion extract cream that is similar to Mederma.
It may help flatten old scars, reduce discoloration, and fade away blemishes.
Due to the mixed clinical research on onion extract, I currently recommend using silicone gels or silicone sheets for effective scar treatment and prevention.
My top pick for a silicone gel is NewGel+ (I use it myself).
For large body scars, I recommend a silicone sheet like ScarAway Silicone Scar Sheets.
