If you are dealing with a raised, itchy, or discolored keloid scar, the one ingredient that matters more than any other is silicone. The most effective options on the market are built on medical-grade silicone, which works by creating a protective, moisture-locking layer over the scar tissue that helps soften and flatten it over time. This guide breaks down the top silicone-based creams, gels, and sheets so you can match the right format to your scar, your skin, and your daily routine.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Here is the focused breakdown of the best cream for keloid scars to help you choose a silicone-based formula that fits your routine and budget.
Our Picks at a Glance
How To Choose The Best Cream For Keloid Scars
Keloid scars are thick, raised areas of excess collagen that grow beyond the original wound boundary. They respond best to consistent, daily treatment, and silicone is the ingredient with the most clinical support for softening and flattening them.
Gel, Cream, or Sheet? Match the Format to Your Life
A silicone gel or cream is the easiest to apply on awkward spots like the face, neck, or joints, and it dries into a clear, invisible layer you can wear under makeup. Silicone sheets and tapes provide continuous pressure and a sealed, waterproof barrier, which makes them a strong choice for large or stubborn scars on the torso or limbs, especially while you sleep.
Check the Silicone Concentration and Formula
Look for products that explicitly state they are made with medical-grade silicone, and check whether the formula includes extra helpers like vitamin C or Centella Asiatica. These added ingredients can brighten discoloration and calm redness, but the silicone is what does the heavy lifting for flattening a raised keloid.
New Scar vs. Old Scar Timelines
A fresh scar responds faster, often showing visible improvement within weeks, while a scar that has been present for years needs months of patient, daily application. Set realistic expectations before you start, and stay consistent, because skipping days slows progress noticeably.

In‑Depth Reviews
1. Wewell Professional Silicone Gel
Our pick — over 4.5★ from 200+ verified ratings; the strongest balance of quality and price.
The daily driver that tackles acne, surgery, and burn marks with one medical-grade silicone formula.
This pick earns the top spot because it is built around premium medical-grade silicone, the ingredient with the most clinical support for smoothing new and old scars. It is designed to work across a wide range of concerns, from acne marks and surgical scars to stretch marks and burn scars, making it a true one-bottle solution for anyone with multiple scars in different places.
What wins people over is the visible progress. Buyers report that with everyday use, scars fade and the raised bump of a keloid flattens out within a few weeks. The formula is also light enough that it layers well under other products, which matters if you are treating a scar on your face or another visible spot during the day.
The main catch is the ingredient debate. A rare few buyers question whether the silicone in the jar is truly medical-grade, pointing to dimethicone on the label as a cheaper alternative, so if ingredient purity is your top concern, read the full list before committing.
What Owners Love
- Visible fading and flattening of keloids within a few weeks of daily use
- Covers a wide range of scar types, from acne to C-section
- Lightweight feel that works well under makeup or sunscreen
The Trade-Off
- Occasional questions about whether the silicone grade matches the “medical-grade” claim
- Needs consistent everyday application to see results
Reach for this if: you want one versatile silicone gel that covers everything from a fresh surgical scar to an old stretch mark, without switching products.
Look elsewhere if: you demand absolute clarity on ingredient sourcing, since this one carries a small question mark over its silicone grade.
2. Rvlaim Silicone Scar Sheets
A single 157-inch roll that you cut to size and reuse for months of coverage.
This is the format for people who want continuous pressure on a scar, not just a topical layer. The roll measures 1.8 inches wide and 157 inches long, and you cut a piece to fit your scar exactly, so nothing goes to waste. It applies gentle physical pressure that limits sideways scar growth, which is exactly what a raised keloid needs.
The thing everyone raves about is how well it stays put. Owners mention the adhesive survives exercise and daily showers, and some saw improvement in as little as five days on a fresh surgical scar. The roll is also a serious money-saver; the maker says one box lasts over three months since the sheets can be cleaned and reapplied, and at 3.21 ounces this roll is more than twice the weight of the Wewell gel bottle, so you are getting a lot of material for the money.
The honest limit is placement. A scar on your palm or another high-flex area is a tough spot for any tape, and some owners switch to a cream there for easier application.
Why It Stands Out
- Cut-to-size roll means zero waste and full control over coverage
- Stays on through workouts and showers, even overnight
- Reusable sheets make the long-term cost much lower
Who Should Skip
- Tape struggles to stay on high-flex spots like palms
- Requires cutting and re-applying that a cream does not
Pick this for: a large, flat scar on your torso or limbs where you can leave a sheet on for hours at a time.
skip it if: your scar sits on a joint or palm where adhesive simply will not hold.
3. Rvlaim Silicone Scar Cream
Fast-drying and fragrance-free, this is the cream you forget you are wearing.
If you hate the sticky, greasy feeling some scar treatments leave behind, this 1.7 oz cream is the answer. It is formulated to dry quickly with a lightweight, non-greasy texture that leaves no white cast, so it disappears under clothing or makeup. That makes it an easy pick for daytime use when you do not want a visible treatment on your skin.
What wins people over is the feel paired with results. The formula includes Centella Asiatica, an ingredient that helps calm redness while the silicone softens scar tissue and locks in hydration. Customers note visible improvement in scar texture and a significant reduction in appearance, with several noting it layers cleanly under sunscreen.
The one thing to know is that this is a bigger tube than the Wewell gel — 1.7 oz versus 1 oz — so you get roughly 70% more product for your routine. It still needs that daily, consistent application to earn its results.
The Highlights
- Dries fast with zero sticky residue or white cast
- Fragrance-free and alcohol-free, gentle for sensitive skin
- Larger 1.7 oz tube gives you more product to work with
The Catch
- Results depend on consistent 2–3 times daily application
- Lighter texture means less occlusive pressure than a sheet
Best for: anyone who wants a comfortable, invisible treatment they can wear all day without that greasy feeling.
Not for: those who prefer the hands-off, leave-it-on-hours approach of a silicone sheet.
4. Rejuvaskin Silicone Scar Gel
A 97% liquid silicone gel that soothes the itch while it flattens the bump.
This gel is built around a high concentration of liquid silicone — 97% — which is about as potent as silicone treatments get. That strength makes it a solid choice for hypertrophic scars, keloids, and surgical scars that need real flattening power. It also blends in vitamin C and squalane, which help brighten discoloration and calm the itchiness that often comes with healing scars.
The formula is clear, odorless, and water-resistant, drying into an invisible barrier you can wear under makeup or sunscreen without clogging pores. Reviewers point out it smooths an entire incision line and helps with itching after surgery, and it earned praise for treating a chemical burn by evening out skin tone in weeks.
The trade-off is size and cost. This is a 10 mL tube, which is noticeably small for the money, and a few owners call it sample-sized; if you are treating a large scar, you will run through it fast. If you want a bigger bottle, the RejuvaSil 30ml version below gives you three times the product.
What Makes It Strong
- High 97% liquid silicone concentration for real flattening power
- Vitamin C brightens discoloration while squalane calms itch
- Clear, non-greasy, and safe under makeup
What Holds It Back
- 10 mL tube is small for the price
- A few sensitive-skin users report irritation
Choose this if: you have a small, itchy, raised scar that needs a high-potency silicone with soothing extras.
Think twice if: you are treating a large area, since the tiny tube will not last long.
5. Cicatricure Advanced Scar Gel
A clinically positioned gel that promises visible change in as little as two weeks.
This gel markets itself on speed, with a claim of visible improvement in surgical scars, acne scars, and stretch marks within two weeks. It is built around a Regenerare Complex with hydrating agents that smooth texture and reduce the appearance of scars, and it works on both non-keloid and hypertrophic scars.
Buyers confirm the results, with several reporting noticeable changes in color, texture, and smoothness after a few weeks of consistent use. The formula is lightweight and non-greasy, absorbing quickly so it is comfortable for the four-times-a-day application the maker recommends. It is also a solid value at 2 oz, giving you more product than most tubes in this list.
The honest caveat is that speed depends on the scar. Owners note it works best on scars under two years old, so a long-standing keloid will need more patience.
The Appeal
- Clinically positioned for visible results in two weeks
- Large 2 oz tube is strong value for the money
- Lightweight, fast-absorbing formula for 4x daily use
The Reality Check
- Old scars need months, not weeks, to show change
- Requires frequent reapplication throughout the day
Reach for it if: you want a generous tube with a fast-results promise and do not mind applying it several times a day.
Pass if: your scar is many years old and you expect a quick fix.
6. Rejuvaskin RejuvaSil Silicone Scar Gel
The bigger 30ml bottle of the brand’s trusted silicone gel for slow, steady scar remodeling.
This is the larger sibling of the 10 mL Rejuvaskin gel above, giving you three times the product at 30ml for a long-term treatment plan. It combines silicone with a botanical blend to form a semi-occlusive barrier that supports the skin’s natural healing process, which is exactly what a raised keloid needs over many months.
Shoppers say strong results on post-surgery and burn scars, with visible fading and smoothing within two weeks of use. One owner used it on a scar revision for over two years and found the scar became smoother, softer, and flatter, though some redness remained. The formula is praised for moisturizing well and for being less irritating than silicone sheets, which can tug at the skin.
The honest note is that this is a marathon, not a sprint. Old scars need months of consistent application, and while the gel works, it will not erase a scar overnight.
The Strengths
- Three times the product of the 10 mL version for long-term use
- Moisturizing, smooth texture that layers well
- Botanical blend soothes while silicone flattens
The Patience Test
- Old scars need months of daily application
- Some redness may remain even after long use
Best for: someone committed to a months-long routine who wants a generous bottle of a proven silicone gel.
Not for: anyone expecting a quick fix or wanting a sheet-style treatment.
7. ScarAway Scar Fabric Sheets
Pre-cut fabric sheets that stick for days and keep new scars from turning into keloids.
These are self-adhesive, water-resistant fabric sheets designed for the treatment and prevention of hypertrophic and keloid scars from injuries, burns, and surgeries. Each sheet is 1.5×3 inches, and you get 8 of them in a box, which means you can cut them to size and rotate them across a healing wound.
The standout feature is durability. Each sheet is rated to last 7-10 days of coverage, far longer than most tapes, and buyers confirm they survive showers and even exercise. One owner found the clear version stuck to their arm for five days straight and the scar faded completely; another reported the bump of a very old scar going down on the first use.
The recurring gripe is adhesion on tricky spots. A few owners note the sheets do not stick well on the neck, and one found parts lifting on the skin. If you need a sweat-proof option for a high-movement area, this is worth testing.
Why It Works
- Each sheet lasts 7-10 days, so you change it rarely
- Water-resistant and comfortable for daily wear
- Pre-cut squares are easy to trim to any scar
The Limitation
- Adhesion can fail on the neck or curved areas
- Needs multiple boxes for a months-long routine
Choose this if: you want a low-maintenance, reusable sheet that you can leave on for a week at a time.
Skip if: your scar sits on a curved or high-flex spot where adhesive keeps lifting.
8. NewGel+ UV Medical-Grade Silicone Scar Cream SPF 30
The only pick here that pairs medical-grade silicone with SPF 30 sun protection in one tube.
This is the smart choice for scars on sun-exposed areas like the face, arms, and hands. It combines 100% medical-grade silicone with zinc oxide, a broad-spectrum SPF 30 mineral sunscreen, so it protects your scar from darkening while the silicone works to flatten and fade it. That matters because UV exposure can permanently discolor a healing scar.
The honest downside is the size. At 0.5 oz, this is the smallest tube on the list, and a few owners find it expensive for the amount you get. It is best used strategically on visible, sun-exposed scars rather than large body areas.
The Big Win
- SPF 30 zinc-oxide sunscreen prevents UV darkening
- 100% medical-grade silicone for flattening power
- Scentless and non-irritating, safe for kids
The Cost
- Tiny 0.5 oz tube is pricey for the amount
- Mixed feedback on skin irritation in some users
Reach for this if: your keloid sits on your face or another spot that sees daily sun and you want two-in-one protection.
Look elsewhere if: you need to treat a large area, since the small tube will disappear fast.
9. Molnlycke Mepiform Silicone Sheeting
The hospital-grade silicone sheet that stays on for days and repositions without pain.
This is the premium, clinical option from Mölnlycke Health Care, a world-leading maker of wound care and surgical products. Each box contains 5 sheets measuring 4×7 inches, the largest individual sheets on this list, and they are designed specifically for the management of hypertrophic and keloid scars. The design goal is 24-hour wear, with a thin, flexible build that is discreet under clothing.
The defining feature is Safetac Technology, a soft silicone adhesive that minimizes pain and trauma at dressing changes, so you can peel it off, reposition it, and reapply it without damaging the healing skin underneath. Owners mention dramatic improvement on old keloid scars, with reduced redness, smoother texture, and a flatter profile after days of use. One owner found it life-changing for a large arm scar that was catching on clothing.
The reality is the investment. This is the most expensive option here, and a few customers note the delivery boxes can arrive crinkled, though the sheets themselves hold up. If you want the most clinically respected, hospital-grade option for a large scar, this is it.
The Clinical Edge
- Large 4x7in sheets cover big scars in one piece
- Safetac Technology allows painless repositioning
- Hospital-grade brand trusted by healthcare pros
The Investment
- Highest price point on this list
- Occasional delivery boxes arrive damaged
Worth it for: a large, stubborn keloid where you want the most clinically respected silicone sheet available.
Not for: budget-conscious buyers or those treating a tiny scar who do not need this much sheet material.
Understanding the Specs
Silicone Concentration
This is the single most important number on the label. Look for products that explicitly say “medical-grade” silicone or list a high percentage, like the Rejuvaskin gel at 97% liquid silicone. Higher concentration generally means more flattening power, but even a well-formulated lower-dose cream can work well with daily use.
Format: Gel vs. Sheet
Gels and creams are easiest for the face, neck, and joints, drying into an invisible layer you can wear under makeup. Sheets and tapes provide continuous pressure and a waterproof barrier, which is ideal for large or flat scars on the torso and limbs. Many people use a gel during the day and a sheet overnight.
Added Ingredients
Beyond silicone, look for helpers like vitamin C to brighten discoloration, squalane or emu oil to soothe itch, and Centella Asiatica to calm redness. These extras do not replace the silicone, but they speed up the cosmetic improvement of the scar’s color and texture.
SPF Protection
UV exposure darkens scar tissue permanently, so any scar on a sun-exposed area needs protection. A silicone cream with built-in SPF, like the NewGel+ UV option, is the smartest way to handle face and hand scars in one step, rather than layering two separate products.
