Silicone Sheeting Is the First-Line Treatment for Keloids
If you want a clear answer to what actually works for a keloid, start here. Silicone gel sheeting is one of only two evidence-based options the International Advisory Panel recommends as a first-line choice for hypertrophic scars and keloids, alongside intralesional corticosteroid injection [1]. Results from at least eight randomized controlled trials and a meta-study of 27 trials support its use.
The mechanism is straightforward. The silicone sheet creates occlusion over the scar and keeps the skin hydrated. That damp environment supports faster reepithelialization and decreases collagen deposition, which reduces the overproduction that makes a keloid grow, per the evidence review at PMC [2].
One honest note up front: silicone gel sheeting does not tend to fully resolve a keloid. It modulates keloid formation and can reduce thickness and firmness, with few associated side effects, per the same review [2]. That makes it the safe, gentle place to begin.
Below you will find the full step-by-step protocol, the complete menu of options for when silicone alone is not enough, and a section written specifically for melanin-rich skin.
Why Keloids Are Different From Regular Scars
A keloid is scar tissue that grows beyond the border of the original wound and does not shrink back on its own. That is the defining feature.
A hypertrophic scar is different. It stays within the wound border and often flattens over time. The distinction matters because it shapes how each responds to silicone, per the noninvasive and invasive treatment review and Mayo Clinic [3] [4].
Keloids sit on a deeper, more established collagen deposit. That is why they need longer daily wear times and longer courses than a typical scar, a point covered in detail later. The excess tissue took longer to form, so it takes longer to soften.
Two more facts set up the rest of this guide. Untreated keloids can keep growing over time, and they are prone to coming back after surgical removal. A keloid is a scar-tissue response, not a flaw or something you did wrong.
As Dr. Hadley King, dermatologist, explains: "Scars are the result of the skin's wound-healing cascade, which includes inflammation, new collagen deposition, and long-term remodeling... Silicone helps normalize collagen production and reduce excess thickness, while hydration supports skin flexibility and barrier repair."
The Silicone Sheet Protocol Dermatologists Actually Recommend
Here is the protocol in a clear sequence you can follow at home. Silicone sheeting suits new or fresh keloids and smaller, flatter keloids used consistently. Larger, longer-standing, or fast-growing keloids usually need the escalation path in the next section.
Step 1: Confirm the Wound Is Fully Closed Before Starting
Only begin once the skin has fully reepithelialized, with no scabs and no open areas. Applying silicone before this point does not work, per the PMC evidence review [2].
It is also a safety matter. The Nuvadermis Silicone Scar Sheets are for intact skin only and should not be used on open wounds. Wait for the surface to close, then start.
Step 2: Apply the Right Amount of Daily Wear Time
Aim for a minimum of 12 hours per day, increasing to 24 hours per day where your skin tolerates it, per the International Clinical Recommendations [1].
If your skin is sensitive, ramp up gradually. The JCAD topical silicone sheet study used a gentle onboarding method: start with 3 hours on day one, then add 1 to 2 hours each day until you reach 20 to 24 hours [5]. Cover the scar and overlap the borders by at least 2 cm.
Step 3: Stay Consistent for the Full Treatment Window
For keloids specifically, plan for at least 3 to 6 months of consistent daily wear. The Cochrane review notes that people with keloid scars need to wear the sheet consistently to get the most from it [6].
Sheets are cleaned daily and reused for several weeks before you replace them, per the JCAD study and the Nuvadermis product care instructions [5]. Rinse the skin and the sheet, let both dry, then reapply.
Step 4: Know What Progress Looks Like
Visible change follows a typical order. Texture softens first, then pigmentation evens out, then height flattens, per the PMC review [2].
Do not judge the protocol as failing if height has not changed by the end of month one. Flattening is the last stage to show, and it is the slowest. Keep going through the full window.
Nuvadermis Silicone Scar Sheets and Silicone Scar Tape are the applied version of this exact routine: 24-hour wearable, reusable, and trimmable to fit. For a full application walkthrough, see Clinically Proven Nuvadermis Silicone Sheets Fade Scars.
When Silicone Alone Isn't Enough: The Full Keloid Treatment Landscape
Silicone is the starting point. When a keloid is large, older, or does not respond, dermatologists reach for other options, often two or more together. Using two or more types of treatment often improves results, per the American Academy of Dermatology and the noninvasive and invasive review [7] [3].
| Treatment | How It Works | Typical Timeline | Best For |
|---|---|---|---|
| Silicone sheeting/gel | Occlusion and hydration reduce collagen overproduction and soften the scar | 12–24 hours/day for 3–6 months | New and smaller, flatter keloids; non-invasive first step |
| Corticosteroid injections | Cortisone or steroid injected into the keloid reduces thickness | Monthly injections for up to 6 months (Mayo Clinic) | Smaller keloids |
| Cryotherapy | Freezing the scar reduces its size | In-office sessions, often repeated | Small keloids (Mayo Clinic, PS Dermatology Group) |
| Laser therapy | Reduces height and fades color; often paired with other options | Repeated in-office sessions | Larger or older keloids (AAD) |
| Pressure therapy | Compression dressings or garments limit blood flow and scar growth | 12–24 hours/day for 4–6 months (Mayo Clinic) | Newer keloids and post-surgery care |
| Surgical excision | The keloid is removed under local anesthesia | Single procedure plus follow-up | Keloids not responding to other options; must be paired with adjuvant therapy because excision alone carries a high recurrence risk (PMC review) |
Surgery deserves a clear caveat. Excision alone carries a high risk of the keloid returning [4], so it should always be combined with an adjuvant such as corticosteroid injections, silicone sheeting, or radiation, per the PMC review and the International Clinical Recommendations [2] [1].
Combination care is common: silicone sheeting plus corticosteroid injections, or pressure plus silicone. For a broader look at how these approaches rank against each other, see The Best Scar Care Products, Ranked by Science. Within this full picture, silicone sheets and tape are the recommended non-invasive place to begin.
Keloid Care for Melanin-Rich Skin
People with more melanin-rich skin are understood clinically to be more prone to forming keloids. If that describes you, a dermatologist can give you a personal risk assessment, which is more useful than any general figure.
There is one concrete, sourced fact worth acting on today. Sun exposure can permanently darken a keloid and make it more noticeable, so daily broad-spectrum SPF 30+ is non-negotiable, per Mayo Clinic's keloid self-care guidance [4].
The silicone sheet protocol is the same regardless of skin tone. What changes is how closely you watch pigmentation. Any new darkening should prompt a dermatologist check-in rather than more aggressive at-home care.
For the full pigmentation-safe daily routine, see A Dermatologist's Guide to Managing Scars on Melanin-Rich Skin. This section summarizes the essentials; that guide covers the expanded routine.
Adjusting the Protocol to Avoid Hyperpigmentation
Start gentle. Silicone before injections or laser is the sensible order on melanin-rich skin, because more aggressive procedures can carry a higher risk of hyperpigmentation, as noted in the melanin-rich skin guide.
Pair the sheet with daily sunscreen and keep the routine consistent. If the surrounding skin darkens or reacts, pause and speak with a dermatologist before continuing rather than layering on more at home.
When to See a Dermatologist
A few clear signals mean it is time for professional input. See a dermatologist if you notice no improvement after a full 3 to 6 month silicone course, continued growth, pain, or a keloid large enough that at-home pressure or silicone is not practical.
A dermatologist can confirm the diagnosis and combine silicone sheeting with corticosteroid injections, the standard first-line combination for keloids that do not resolve with silicone alone, per the International Clinical Recommendations and the PMC review [1] [3].
This is not a sign the at-home protocol failed. Dermatologists often recommend combining more than one approach for a keloid, per the AAD, so combination care is the norm [7]. Think of professional care as the next natural step in a continuum.
Nuvadermis Silicone Scar Sheets: The Protocol, Applied
Here is what the protocol above looks like day to day. Nuvadermis makes two at-home formats of the same routine.
The Nuvadermis Silicone Scar Sheets are soft, breathable, medical-grade silicone. They are trimmable for a custom fit, comfortable enough for 24-hour wear, and reusable for about a week with daily cleaning. Nuvadermis Silicone Scar Tape has the same wearable format in a strip.
Both help reduce the appearance of new and old scars, including keloid, surgical, and C-section scars, by improving tone, texture, and smoothness. Clean and dry the scar area, apply the sheet with a 2 cm overlap on all sides, then wear, rinse, and reuse.
To start the protocol, shop the Silicone Scar Sheets.
Frequently Asked Questions
What is the most effective treatment for keloid scars?
Corticosteroid injections and silicone gel sheeting are the two evidence-based first-line treatments for keloids, per the International Advisory Panel on hypertrophic scar and keloid management. Silicone sheeting is the better starting point for smaller, newer keloids since it's non-invasive; larger or treatment-resistant keloids typically need injections, laser, or surgery paired with adjuvant therapy.
Can Keloids Be Prevented After a Wound or Surgery?
You can help lower the risk. Silicone gel sheeting can be used preventively for patients with a history of keloids once the wound is fully closed, per the PMC review [2]. Pressure dressings after surgery and daily sun protection also support the area as it settles. If you know you are prone to keloids, tell your surgeon before any planned procedure so they can plan follow-up care.
Which Areas of the Body Are Most Prone to Developing Keloids?
Keloids tend to form on areas with more skin tension and thicker skin, such as the chest, shoulders, upper back, and earlobes after piercings. The location often shapes which formats are practical, since a flat sheet works well on a chest but tape or a pressure earring may suit an earlobe better.
What is silicone scar tape and how is it different from silicone sheets?
Both use the same medical-grade silicone mechanism, hydration and occlusion to reduce collagen overproduction. Tape comes in a strip format, better suited to narrow or linear scars like surgical incisions, while sheets cover broader areas. Nuvadermis makes both as at-home formats of the same clinically supported protocol.
What's the Difference Between Over-the-Counter and Medical-Grade Silicone Products?
Both use silicone, but medical-grade silicone is held to stricter material and hygiene standards. Nuvadermis sheets are made from medical-grade silicone, third-party tested, and developed under strict hygienic standards. That matters for a product worn on the skin for many hours a day over months.
Can Silicone Sheets Be Combined With Corticosteroid Injections or Other Treatments?
Yes, and this pairing is common practice. Silicone softens the scar tissue, which can make injections more comfortable and effective, and the two are frequently used together as described earlier in this guide.
Can a Keloid Come Back After Being Surgically Removed?
Yes. As covered above, excision alone carries a high recurrence risk, so surgery is almost always paired with an adjuvant. Continuing silicone sheeting after the wound closes is one way to support the area and reduce the chance of regrowth.
Silicone sheeting gives you a safe, evidence-backed way to start managing a keloid at home. Confirm the wound is closed, then wear the sheet 12 to 24 hours a day. Stay consistent for 3 to 6 months. If growth continues or nothing shifts by the end of that window, a dermatologist can add injections or another option to the plan.
