Scar tissue is stubborn. Whether from a C-section, a kitchen burn, or a decade-old acne mark, the fibrous collagen that forms during healing creates a texture and color that stands out against healthy skin. An effective scar ointment works by breaking down that excess collagen, hydrating the stratum corneum, and signaling fibroblasts to rebuild more evenly. The right formula—typically built around medical-grade silicone, onion extract, or a blend of bio-available oils—can visibly flatten, soften, and fade a scar within 8 to 12 weeks of consistent use.
I’m Mohammad — the founder and writer behind ProteinJug. I’ve spent years analyzing dermatological actives, comparing clinical trial data on scar therapies, and cross-referencing thousands of real-user outcomes to identify which ointments actually deliver measurable improvement in pigmentation and texture.
Five products made the final cut — each tested against the same criteria: active ingredient concentration, real-world application texture, and reported results at 8 weeks. This guide breaks down the data so you can confidently choose the best ointment to remove scars for your specific skin type and scar history.
How To Choose The Best Ointment To Remove Scars
Not all scar creams are built alike. Some rely on occlusive silicone to create a moisture barrier, while others use botanical enzymes to break down collagen bundles. Your choice depends on the scar’s age, location, and whether it is raised, flat, or pigmented. Here are the four factors that separate a wasted tube from a treatment that actually works.
Active Ingredient: Silicone vs. Onion Extract vs. Enzymatic Oils
Silicone (dimethicone or cyclomethicone) is the current clinical gold standard — it hydrates the scar surface and down-regulates fibroblast activity, which reduces bulk in raised scars. Onion extract (Allium cepa) has anti-inflammatory properties and inhibits fibroblast proliferation, making it effective for flattening hypertrophic scars. Oil-based formulas with vitamin E, emu oil, or squalene work better on mature, flat, pigmented scars by improving moisture retention and promoting cell turnover. If your scar is red and raised, choose silicone. If it is brown and flat, an oil-serum blend is often more effective.
Scar Age and Treatment Duration
New scars (under 6 months) respond fastest because collagen is still remodeling. An 8-week course of twice-daily application is the minimum for visible change. Old scars (over 2 years) require 3 to 6 months of consistent use and a higher concentration of active ingredients. Do not expect a cream to erase a scar completely — realistic improvement is a 30–60% reduction in visibility, texture, and pigmentation. If you stop after two weeks, you will see nothing. Commitment is the active ingredient that is never listed on the label.
Texture, Absorption, and Daily Usability
A thick gel that balls up under makeup or sunscreen will not get used consistently. Look for a fast-drying, non-greasy formula that layers cleanly under SPF and cosmetics. For body scars on knees, elbows, or the chest, a water-resistant silicone gel that stays put through sweat and movement matters more than a light lotion. For facial scars near the nose or mouth, a fragrance-free, hypoallergenic gel prevents irritation and stinging during reapplication. The best ointment is the one you will actually apply twice a day for three months.
Hypoallergenic and Skin Sensitivity Profiles
Sensitive skin reacts to fragrances, parabens, and certain preservatives common in lower-tier scar products. If you have eczema, rosacea, or a history of contact dermatitis, choose a formula that is explicitly fragrance-free, non-comedogenic, and dermatologist-tested for reactive skin. Silicone gels are generally inert, but some adhesives in sheet-based silicone products can cause irritation. An oil-based serum with chamomile or lavender can soothe while it treats — just patch test on your inner arm before applying to the scar line.

In‑Depth Reviews
1. Rejuvaskin RejuvaSil Silicone Scar Gel
RejuvaSil is a pure silicone gel fortified with emu oil, vitamin C, and squalene — a combination that both hydrates the scar surface and delivers antioxidants to support melanin normalization. The 0.33-ounce tube is compact, but the gel spreads thinly, so it lasts roughly 6–8 weeks of twice-daily use on a 2-inch scar line. The texture dries to a clear, non-sticky film that does not ball up under sunscreen or makeup, making it a viable option for facial scars near the jawline or cheek.
Real-world feedback from users with open-heart surgery scars and old acne pitting shows softening and flattening within 4–5 weeks, with continued improvement through week 12. Multiple reviewers noted that it soothes the itching and discomfort that often accompany healing keloids — a benefit of the squalene and emu oil blend. One user who had reacted to other silicone gels (including a well-known brand recommended by their plastic surgeon) tolerated RejuvaSil without any stinging or rash.
The main compromise is the small tube size relative to the price point. If you are treating a long surgical scar (6 inches or more) or multiple scattered acne scars, you will need to repurchase more frequently than with larger-volume competitors. For anyone with sensitive, reactive skin who needs a silicone gel that actually stays on without irritation, this is the strongest formulation available.
Why it’s great
- Hypoallergenic — safe for even the most reactive skin types
- Dries clear and non-sticky, layers well under makeup
- Contains emu oil and squalene for added moisture and itch relief
Good to know
- Only 0.33 oz — smaller tube than most mid-range options
- Requires twice-daily application for at least 8 weeks to see results
2. Mederma Advanced Scar Gel
Mederma is the most recognized name in scar treatment, and its Advanced Scar Gel formula is built around a patented onion extract concentrate that penetrates below the skin’s surface to influence collagen production and cell renewal. The gel is lightweight, absorbs in under a minute without a greasy residue, and has a faint medicinal scent that dissipates quickly. The 0.70-ounce tube is bigger than the premium silicone options, making it a more economical choice for covering larger or multiple scars.
User data is strong for both new and old scars: post-burn wounds that looked aggressive healed to barely visible within 6 weeks, and older dark acne spots showed gradual lightening after 3 months of consistent daily use. A handful of reviewers noted that the tube seems small for the recommended 3–6 month treatment window on older scars, but cutting open the tube at the end yields enough leftover product for another week or two. Surgeons, pediatricians, and dermatologists recommend Mederra more than any other scar brand in survey data.
The main trade-off is the active delivery mechanism — onion extract works well for hypertrophic and pigmented scars but is less effective on true keloids compared to an occlusive silicone barrier. If your scar is raised, red, and warm to the touch, a silicone gel will flatten it faster. For flat, brown, or purple scars, Mederma is excellent.
Why it’s great
- Clinically shown to reduce old and new scar appearance
- Absorbs quickly with no sticky feel
- Trusted by plastic surgeons and pediatricians
Good to know
- Tube size is small for the recommended 3–6 month regimen
- Onion extract less effective on thick, raised keloids than silicone
3. Ebanel Silicone Scar Gel with Allantoin & Emu Oil
Ebanel’s gel combines three actives — medical-grade silicone, onion extract, and allantoin — into a single 1-ounce tube that covers more surface area per application than any other gel on this list. Allantoin is a keratolytic agent that gently exfoliates the top layer of dead skin cells, allowing the silicone and emu oil to penetrate the scar bed more effectively. The texture is thicker than the RejuvaSil or Mederma gels, which some users found difficult to spread across large areas like the thigh or abdomen.
User reviews highlight its effectiveness on hyperpigmentation from ingrown hairs and acne spots, with visible fading reported within 3–4 weeks of consistent twice-daily use. Several customers noted that the gel feels slightly tacky during the first minute after application, but it dries down clear and odorless. The formula is made in an FDA-registered facility in the USA and is fragrance-free, making it safe for sensitive skin that reacts to botanical extracts in other products.
The thicker viscosity is the main friction point. It works well for spot-treating a 1–2 inch scar, but covering a 6-inch C-section line requires careful spreading and a bit more patience. For the price, you get 3x the volume of the premium silicone gels, making it the strongest cost-per-ounce value in this guide.
Why it’s great
- 1-ounce tube — significantly more product than competitors
- Triple-active formula: silicone, onion extract, allantoin
- Made in USA in an FDA-registered facility
Good to know
- Thicker texture makes spreading over large scars harder
- Some users felt it required 3+ daily applications for best results
4. Bio-Oil Skincare Body Oil Serum
Bio-Oil is not a silicone gel — it is a lightweight, fast-absorbing oil serum formulated with vitamin E, calendula, lavender, chamomile, and retinyl palmitate. It works through a different mechanism: it hydrates the stratum corneum, supports collagen repair via vitamin A, and calms inflammation with chamomile. It is ideal for old, flat, pigmented scars that no longer have active collagen buildup. Users with PCOS-related hormonal acne reported that it consistently faded dark marks within 6–12 months without clogging pores.
The oil texture is surprisingly non-greasy when used sparingly — three drops cover a 3-inch scar line. It absorbs within 30 seconds and leaves the skin feeling soft rather than slick. Multiple reviewers noted its versatility: it works on facial scars, body stretch marks, and even fresh surgical wounds once the skin has fully closed. It is also vegan, cruelty-free, and packaged in a 100% recyclable bottle.
The limitation is that Bio-Oil does not physically flatten raised or hypertrophic scars. If your scar is thick and rope-like, an occlusive silicone gel will deliver better results. For discoloration and texture improvement on flat scars, Bio-Oil is the most pleasant daily-use option in this guide.
Why it’s great
- Fast-absorbing, non-greasy oil suitable for face and body
- Clinically proven to improve scar pigmentation and stretch marks
- Vegan, cruelty-free, and non-comedogenic
Good to know
- Not effective on raised or keloid scars — no occlusive barrier
- Results require 3–6 months of consistent daily use
5. Rvlaim Silicone Scar Sheets (4M Roll)
Rvlaim’s silicone scar sheets are an occlusive barrier delivery system — a 157-inch roll of medical-grade silicone tape that applies continuous pressure and a moist healing environment to the scar 24/7. Unlike gels that wash off, these sheets stay on through showers and exercise, providing round-the-clock treatment. The 1.8-inch width covers most C-section and surgical scars in a single strip, and the roll can be cut to custom shapes for keloids on the chest, shoulder, or earlobe.
User feedback overwhelmingly confirms that the sheets flatten raised scars and reduce redness more reliably than gels, especially for keloids and hypertrophic scars that have a thick, ropey feel. One user with a 20-year-old appendicitis scar reported that consistent use smoothed the raised appearance and made it less visible. The sheets are hypoallergenic and free of parabens and latex, but a small number of users with adhesive sensitivity experienced irritation around the edges of the tape.
The main disadvantage is the visual presence — even though the sheets are skin-colored, they are visible on exposed areas like the neck or forearm. They also require cleaning with mild soap and water every 1–2 days to maintain adhesion, which adds a step to your routine. For maximum flattening on a keloid or hypertrophic scar, this is the most powerful tool in the guide.
Why it’s great
- Continuous 24/7 occlusion — more effective than gels on raised scars
- 157-inch roll is the most volume for the price
- Reusable — one roll lasts over 3 months
Good to know
- Visible on exposed skin — not ideal for face or neck
- Adhesive can irritate sensitive skin in some users
