Scar Gel

Walk into any drugstore and the scar gel aisle is basically one product: Mederma. The orange box, the onion-extract claim, the same positioning since the late nineties. Derma E's Scar Gel sits on the same shelf with a quieter green label and the same active ingredient class, and most shoppers walk right past it. Here's the interesting thing, though — if you actually read the INCI lists side by side, this formula is arguably the better-rounded of the two. Both products rely on Allium cepa bulb extract, the onion-derived active that's been studied for its flavonoid content and its effect on fibroblast activity in healing tissue. What Derma E does differently is pair that active with panthenol at the second position on the ingredient list, followed by glycerin, and then allantoin a few slots down. Panthenol converts to pantothenic acid in skin and has decades of evidence supporting its role in barrier repair and the soothing of compromised tissue. Allantoin is a mild keratolytic with FDA monograph status as a skin protectant. Together with the onion extract, they create a more complete repair matrix than Mederma's simpler formula, at roughly the same price. The texture is one of the reasons the product has the cult-ish user loyalty it does. It's a clear, lightweight gel that spreads thinly and absorbs in about a minute, leaving no visible residue. You can apply it morning and night, which is important because scar treatment is a consistency game — fifteen seconds of daily application for months is what produces the results that single heavy applications do not. Users consistently praise how easy it is to incorporate into a routine without feeling sticky, greasy, or interfering with anything else they put on their face or body. The results follow a predictable pattern. Within the first two to four weeks, most users notice that the scar surface feels softer and more hydrated — that's the panthenol and glycerin doing their job. Visible reduction in scar color and raised texture takes longer: eight to twelve weeks of consistent twice-daily use is typical, and older or deeper scars may need six months or more. This is not a product that delivers the dramatic before-and-after photos you'll see in its marketing within a few weeks. It's a patience product, and the reviewers who love it are the ones who stuck with it. Now, the meaningful limitation. The INCI ends with 'natural fragrance oils,' and that's a choice the formulator should reconsider. Fragrance of any kind — natural or synthetic — is generally discouraged on healing tissue, particularly on recent surgical scars where the skin is still in an early repair phase. For most users, the fragrance level is low and causes no issue, but for people with sensitive or rosacea-prone skin, it's the one ingredient in an otherwise well-built formula that would push me to suggest a patch test first. If this product were fragrance-free, it would be an easier recommendation across the board. Let's also be clear about what any topical scar product, including this one, can and can't do. No over-the-counter or prescription gel will 'erase' an established scar. The underlying collagen structure of a scar is different from surrounding skin and that difference is permanent. What topicals can do is soften the surface, reduce the active inflammation that keeps a scar looking red or raised, improve hydration so the tissue is more pliable, and modestly influence the appearance over time. For atrophic acne scars, post-surgical scars, and stretch marks in their early phase, this gel is worth a try. For deep ice-pick acne scars or severe keloids, silicone sheeting or professional treatments will almost certainly outperform it. Value-wise, at around $25 for 2 oz, it's not the cheapest option on the shelf but it's cheaper than most prestige scar treatments and roughly comparable to Mederma on a per-ounce basis. For anyone building a routine around a specific scar, it's a sensible anchor product to try consistently for at least three months before deciding if it's working. For someone with highly sensitive skin on or around the scar site, a fragrance-free silicone gel is probably a better first choice. But for most users wanting a botanical, vegan, consistently-reviewed scar gel at drugstore prices, this is one of the better options in its category.

Formula

The hero actives that drive this product's performance.

Ingredient	Function	Evidence
Allium Cepa (Onion) Bulb Extract	The same active ingredient class that powers Mederma — onion bulb extract contains quercetin and kaempferol flavonoids that have been studied for their ability to modulate fibroblast activity in healing tissue, helping to soften the appearance of raised or discolored scars when applied consistently over several months. In this formula, it works alongside panthenol and allantoin, which is a more supportive skin-repair matrix than Mederma's original gel offers.	promising
Panthenol (Provitamin B5)	Sits at the second position on the INCI, which is unusually high — it converts to pantothenic acid in skin and has well-documented benefits for barrier repair and the soothing of healing tissue, making it a sensible pairing with onion extract on post-procedure or still-active scars.	well-established
Allantoin	A mild keratolytic and soothing agent with FDA monograph status as a skin protectant — in this gel it supports the softening of the upper layers of scar tissue and calms the mild inflammation that often accompanies healing, working synergistically with panthenol.	well-established
Acetyl Glycyl Beta-Alanine	A peptide-adjacent skin-signaling ingredient marketed for its role in supporting tissue rejuvenation — the evidence is more limited than for the other actives in this formula, but it adds a supportive layer to the onion-and-panthenol base without posing any meaningful irritation risk.	emerging
Glycerin	Third on the INCI, providing the humectant layer that keeps scar tissue supple during the long application period required for visible results — dry, contracted scar tissue responds less well to treatment than well-hydrated tissue, so this isn't filler.	well-established

Evidence

The Science

The core active in this formula is Allium cepa bulb extract, which contains quercetin and kaempferol flavonoids. These compounds have been investigated in multiple controlled trials for their ability to modulate fibroblast activity and reduce the prominence of hypertrophic and surgical scars, with outcomes typically described as modest but measurable. Published studies on onion-extract scar treatments have shown improvements in scar color, texture, and pliability versus vehicle control, though the effect sizes are smaller than those reported for silicone gel sheeting, which remains the most evidence-supported topical intervention for scar management according to current dermatological consensus. The panthenol content is where this formula diverges meaningfully from the dominant competitor. Published studies on topical panthenol document its conversion in skin to pantothenic acid and its role in increasing fibroblast proliferation, supporting re-epithelialization, and reducing transepidermal water loss on compromised tissue. These are directly relevant mechanisms for scar healing, and having it at the second position on the INCI means the concentration is meaningful. Allantoin's keratolytic and soothing effects are well-documented enough for it to hold FDA monograph status as a skin protectant. The acetyl glycyl beta-alanine is a smaller peptide-adjacent ingredient with more limited published evidence, but it poses no meaningful irritation risk. The broader consensus in dermatological literature is that topical onion extract formulas produce modest but real improvement on certain scar types — particularly fresh post-surgical and atrophic scars — when used consistently for at least 8-12 weeks, and that combining them with hydrating and barrier-supporting actives like panthenol may improve outcomes.

Dermatologist Perspective

Dermatologists typically recommend silicone gel sheeting as the first-line over-the-counter treatment for raised and hypertrophic scars, as the evidence base for silicone is stronger than for onion-extract formulas. That said, many board-certified dermatologists consider onion-extract gels a reasonable secondary option or a supportive measure, particularly for users who prefer a vegan, clean-beauty alternative or who find silicone sheeting impractical for the scar's location. This formula is commonly suggested for mild acne scarring, stretch marks in their early post-inflammatory phase, and post-cesarean scars where silicone sheeting is difficult to maintain. Dermatologists frequently note that consistency and SPF protection of the scar during daylight hours are more important than which specific topical is chosen — unprotected sun exposure on a healing scar will darken it more than any gel can lighten it.

Guidance

How to Use

Apply only to fully closed, healed scar tissue — never on open wounds or broken skin. Cleanse the scar area and pat dry. Dispense a small amount of gel onto a fingertip and massage gently into the scar using circular motions for about 30 seconds. Let it absorb for 1-2 minutes before applying any other products over the same area. Apply twice daily, morning and night, for at least 8-12 weeks to see meaningful results, and continue for 3-6 months for older or more established scars. During the day, always apply broad-spectrum SPF 30+ over the scar area — sun exposure is the single biggest cause of scars darkening and failing to fade.

Value Assessment

At around $24.95 for 2 oz, this product is roughly comparable to Mederma on a per-ounce basis and significantly less expensive than prestige silicone-based scar treatments. The value case rests on the claim that the added panthenol and allantoin meaningfully improve outcomes over a bare onion-extract formula, which the ingredient data supports but published comparative studies do not definitively prove. The small size is a limitation — a 2 oz jar lasts about 3-4 months with twice-daily application to a small scar area, and there is no larger or more cost-effective size. For targeted treatment of a small scar, the math works. For treating a larger area like a surgical incision spanning several inches, budget-conscious users may want to compare with a silicone gel sheet.

Who Should Buy

Anyone with mild to moderate scars — surgical, acne-related, or stretch mark — looking for a vegan, affordable topical treatment they can use consistently for several months. Also a reasonable pick for pregnant users needing a clean-beauty option for post-cesarean scar care once the incision has fully closed.

Who Should Skip

People with highly sensitive, rosacea-prone, or recently-healed tissue should consider a fragrance-free silicone gel instead. Anyone with deep ice-pick acne scars, keloids, or severe hypertrophic scars will get better results from professional treatment — laser, microneedling, or steroid injection — than from any topical.

Background

The Scar Gel is one of Derma E's longest-running targeted treatments and has been a staple in the brand's natural-derived 'skin repair' line for years. It was developed to offer a vegan, clean-beauty alternative to Mederma for users who wanted the same onion-extract active in a formula with supporting panthenol and allantoin rather than a bare-bones delivery.

About Derma E Legacy Brand (20+ years)

Derma E has been producing affordable vegan skincare since 1984 and holds Leaping Bunny cruelty-free certification. The Scar Gel is one of the brand's best-selling targeted treatments and sits in a category otherwise dominated by Mederma and silicone gels — Derma E offers a botanical alternative built around onion extract, the same active class Mederma uses.

Brand founded: 1984

Myth vs. Reality

Myth

Scar gels can 'erase' scars completely

Reality

No topical product — prescription or over-the-counter — can fully erase an established scar. This gel and others like it can soften the appearance, reduce redness, and improve texture over time, but the underlying scar structure remains.

Myth

Onion extract is just folk medicine

Reality

While not as strongly evidenced as silicone gel sheeting, onion bulb extract has been studied in multiple controlled trials for its effect on fibroblast activity and scar appearance, with modest but measurable results on certain scar types.
