How to Reduce Scar Tissue Naturally: Nutrients, Enzymes, and What the Evidence Shows
If you are looking for how to reduce scar tissue naturally, start with the honest version of the answer: no nutrient, enzyme, or cream makes an existing scar disappear. What has already formed will not vanish on its own. What you can influence is how well that tissue remodels from here, and that part is largely nutritional. The body builds scar tissue from the same raw materials it uses to build normal skin, and it keeps reworking that tissue long after the surface has closed. This article covers those raw materials, what the evidence for each one actually shows, and where the popular claims run well ahead of the science.
What Scar Tissue Actually Is
A scar is not damaged skin. It is a different kind of repair.
When an injury reaches deep enough into the dermis, the body does not rebuild the original architecture. It lays down collagen quickly to close the gap and stop the bleeding. Speed is the priority.
That speed has a cost. In uninjured skin, collagen fibers run in a woven, multidirectional pattern. In scar tissue, they are laid down densely and largely in one direction. That is why a scar looks different, feels firmer, and does not stretch the way the skin around it does.
Adhesions are the same process, happening internally. An adhesion is internal scar tissue that forms between two surfaces that should slide past each other. After surgery, the repair process can leave fibrous bands that bind tissue layers together, which is why some people describe pulling, tightness, or restricted movement afterward. It is the same collagen response, in a place you cannot see.
Timing matters more than most people expect. In a 2025 review published in Pharmaceutics, inflammation after a wound begins within 24 hours and persists for up to 2 weeks. That window is when the body is deciding how much collagen to lay down and how to arrange it.
A scar is not failed skin. It is a faster, denser repair. The tissue keeps being reworked long after the surface closes, which is exactly why what you eat and drink during that period is worth paying attention to.
Not every scar behaves the same way. In the same review, patients with thermal injuries showed a 70 percent rate of hypertrophic scarring, meaning the scar stays raised and thickened. Why one scar stays flat and another becomes raised is not something the research has settled.
One more honest note. The same review states that the degree of collagen normalization required for a good outcome "is not yet fully established." Researchers can measure collagen. They cannot yet tell you the exact target.
The Building Blocks: Nutrients With Real Consensus Behind Them
This is the part of the topic where the evidence is strongest and least contested. Cleveland Clinic lays out a short list of nutrients it describes as necessary for normal wound repair, and the other major medical institutions agree on the two that carry the most weight in that process, vitamin C and zinc.
The reason the same names keep appearing is that they are not interchangeable. Collagen formation works like an assembly line. Protein supplies the material. Vitamin C and zinc act in the steps that build and cross-link it. Vitamin A helps direct the process. Iron keeps oxygen moving to the site where the work is happening. Miss one and the line runs slower.
Protein
Cleveland Clinic describes protein as helping "repair tissues" and calls it "vital for skin repair and immunity." Collagen is a protein. Without enough dietary protein, the body does not have the raw material to build the scaffold in the first place.
Vitamin C
Cleveland Clinic states that vitamin C "helps with collagen production" and notes that "deficiency has been found to delay the wound healing process." Mayo Clinic describes vitamin C as necessary for wound healing. Harvard Health frames it as playing a key role in creating collagen. All three point the same direction.
Vitamin A
Cleveland Clinic states that vitamin A "helps stimulate collagen" and that "low levels of vitamin A result in delayed wound healing."
One warning you should not skip. Cleveland Clinic specifically advises getting vitamin A "via meals rather than pills," because excessive supplemental vitamin A causes adverse effects, including vision problems and bone pain. Food is the safer route here. This is not a nutrient to megadose.
Zinc
Cleveland Clinic calls zinc "critical to every phase of the wound-healing process" and points to its role in "protein and collagen synthesis." Mayo Clinic likewise describes zinc as important for wound healing and immune function.
Iron
Cleveland Clinic states that iron "provides oxygen to the wound site and helps in healing." Oxygen delivery is easy to overlook and hard to substitute.
Calories, and the rest of the plate
Cleveland Clinic also notes that calories "provide energy to keep the body functioning and promote wound healing." Undereating after surgery works against everything above.
More is not better here. These are nutrients the body uses in defined amounts, not ingredients where a larger dose produces a larger effect. Vitamin A is the clear example, which is why the recommendation there is food first.
The practical catch: requirements vary by body mass, age, activity level, and how severe the injury was. There is no single number that fits everyone. If you want personal targets rather than general ones, a nutritional consultation is one place to start.
Support for the Remodeling Phase
This is the section where the internet is at its most confident and its least accurate.
Start with the mechanism, because the mechanism is real. Bromelain, an enzyme found in pineapple, promotes fibrinolysis, the process that breaks down fibrin. Fibrin is described in the literature as "a key component of thrombi and scar tissue." Bromelain also degrades extracellular matrix proteins, which is why it is used to manage bruising and swelling after nonsurgical cosmetic procedures. That is a mechanism, not an outcome. It explains why researchers are interested in these enzymes, not what a bottle will do for a scar you already have.
Bromelain
The research discusses doses in the range of 200 to 2,000 mg per day, with the suggestion that "best results occur when starting at a dose of 750 to 1,000 mg per day." One combination that appears in the literature is 1,000 mg of bromelain with 500 mg of vitamin C. A trial combining the two in postoperative bimalleolar surgery "led to better outcomes." Those are the doses the research discusses. They are not a recommendation for you personally.
For adhesions specifically, bromelain has been studied in an animal model, in research on intra-abdominal adhesions after surgery. That study is well cited. It was not a human trial. No human clinical trial of any proteolytic enzyme for scar tissue was located in this research at all, and that absence is itself a finding.
The same review flags a practical problem: variability in commercially produced bromelain and the complexity of its active components limit how far it can be developed as a standardized product. Its authors conclude that "larger-scale studies and further research are needed."
Serratiopeptidase
Serratiopeptidase is the enzyme most often sold on the strength of its reputation for scar tissue. The most-cited systematic review of the evidence, published in the International Journal of Surgery in 2013, reaches a conclusion that rarely makes it onto a supplement label: the evidence supporting its use "is based on clinical studies which are of poor methodology."
That is the reviewers' own sentence. It does not mean the enzyme does nothing. It means the human evidence is not strong enough to carry the confidence with which the enzyme is usually sold.
The mechanism is well described. The human outcome data for scar tissue is thin. Both statements are true, and a page that gives you only one of them is selling something.
What this means practically. If you choose an enzyme product, choose it for the general recovery support it may offer, not because a label promised a specific result on a scar. And choose a product whose quality you can check. Agape's standards are documented on the third-party testing page.
Other Ingredients Being Studied
Everything in this section sits earlier in the research pipeline than the nutrients above. The clearest summary of that comes from a 2024 scoping review in Scars, Burns & Healing, which is worth quoting on its own limits:
- 11 studies met the inclusion criteria.
- Only one RCT was included.
- "Conclusive findings are hindered by the scarcity of evidence."
- The review provides "no clear evidence" for several of the supplements it examines.
Quercetin
In laboratory studies, quercetin inhibited keloid fibroblast growth at 20 micrograms per milliliter (p < 0.01). A separate review reported that it elevated hydroxyproline from 0.78 mg/mL to 1.84 mg/mL, and hydroxyproline is a marker of collagen stability. Grade: laboratory work, not a human outcome.
Curcumin
In laboratory studies, curcumin halted keloid and hypertrophic scar fibroblast proliferation at 2.5 and 5 micrograms per milliliter. The review's own verdict is the part to read carefully: "quality of the evidence of these studies on curcumin is low." Grade: laboratory work, and downgraded by the reviewers who compiled it.
Vitamin D
Vitamin D is the clearest example of a finding that cuts both ways. In the same review, oral vitamin D at 2,000 IU per day alongside surgery was associated with an average reduction of 4 mm in scar width. That is the encouraging half.
The other half is the review's own conclusion: "standalone vitamin D supplementation may not enhance scar width outcomes." Separately, a deficiency below 20 ng/mL correlated with worse skin barrier function. Grade: one human signal, contradicted inside the same review.
Essential fatty acids
Keloid patients in this research reported higher omega-6 (linoleic acid) intake, more than 7 to 11 grams per day, and lower omega-3 (ALA) intake, less than 1.1 to 1.5 grams per day.
Read that as a dietary association, not a trial. It describes what people with keloids reported eating. It does not show that changing your fat intake changes your scar. No page should tell you that omega-3 prevents keloids, and nothing in this research supports that sentence.
The nightshade observation
One small study found that a one-week Solanaceae-free diet, meaning a diet without nightshades, significantly reduced scar itching. Itching is one of the most common complaints about a healing scar, which is why the finding circulates as widely as it does. Grade: small and short. It is an interesting lead, not a protocol.
Where the rest of the research sits
A 2025 review in Pharmaceutics adds a list of natural products studied at the laboratory level: Centella asiatica and its compound asiaticoside, EGCG from green tea, gallic acid, oleanolic acid, and vitamin E, which is studied for regulating immune response and gene expression related to structural proteins.
The same review is candid about the distance still to travel. Direct clinical benefits "remain under investigation." It "remains unclear whether this success leads to fewer wound care revisions," and many materials "lack direct evidence of clinical-level improvements."
One more option worth knowing about. Agape also carries a homeopathic line that includes a formula named for scars and adhesions. That line sits under specialty support rather than in the vitamin aisle, and the NET Remedies line is organized by number rather than by condition.
If you want the background on that framing, our guide to homeopathic drainage remedies explains how the numbering works, and our guide to how to take homeopathic remedies covers the routine.
What We Recommend
Everything above was graded on its evidence. The five bottles below are the Agape products that map to those nutrients and enzymes most directly. Each one was checked against the live store before this page went up: active, published, and in stock. Nothing in this section upgrades the evidence in the sections above.
NET Remedies, #10 Scars Adhesions 60 ml Oral Liquid
$27.00 | Read the full label and product details
This is the bottle named for the topic, and the only product in the catalog whose label speaks to scars and adhesion-type discomfort by name. It is a homeopathic preparation rather than a nutrient, which puts it in a different category from everything above: no homeopathic product is FDA approved, and this page is not claiming otherwise. Agape's copy frames it as support for any type of scar tissue, including post-surgery and injury scars, and it is one of the line's products cleared for external use as well as ingestion. One caution carried over from the label: do not spray it on an open wound.
Enzyme Science, Enzyme Defense Pro 60 Capsules
$49.49 | Read the full label and product details
This is the enzyme formula on the list, and it is the direct counterpart to the remodeling section above. The formula includes serratiopeptidase, the enzyme whose most-cited systematic review this article already quoted, alongside a protease blend, nattokinase, and vitamin D3. Read it the way that section reads: the mechanism for proteolytic enzymes is well described, and the human outcome data specific to scar tissue is thin. That makes it a formula to choose for the general recovery support it may offer, not for a result no label can promise. The label directs one capsule daily on an empty stomach or at least two hours after a meal.
Researched Nutritionals, C-RLA Vanilla Caramel Liposomal Vitamin C 10 oz
$59.98 | Read the full label and product details
Vitamin C is the nutrient with the broadest institutional agreement anywhere in this article. Cleveland Clinic, Mayo Clinic, and Harvard Health each describe it as necessary for collagen production and normal wound repair. This formula pairs 1,500 mg of vitamin C per serving with R-lipoic acid in a liposomal preparation, making it the higher of the two vitamin C options here. It is vegan and soy-free, and its own label note is the one to follow: mix two teaspoons in water and take it away from food.
Protocols For Health, Omega 3X 1300 - 60 Softgels
$65.99 | Read the full label and product details
Essential fatty acids enter this article as a dietary association, not a trial. Keloid patients in that research reported higher omega-6 intake and lower omega-3 intake, and that finding does not show that changing your fat intake changes a scar. Nothing here supports a claim that omega-3 keeps keloids from forming, and this page does not make one. What this formula does provide is a concentrated fish oil supplying EPA and DHA, the precursors the body uses to generate the specialized proresolving lipid mediators named on its label. Each softgel carries 430 mg of total omega-3 fatty acids from an IFOS five-star certified oil, and the label direction is one softgel daily.
Integrative Therapeutics, Vitamin C with Quercetin 180 Veg Capsules
$42.50 | Read the full label and product details
Quercetin has its own section above, and its grade there is laboratory work rather than a human outcome: it inhibited keloid fibroblast growth in the lab, and a separate review reported that it raised hydroxyproline, a marker of collagen stability. This formula pairs 450 mg of vitamin C with 250 mg of quercetin dihydrate and 125 mg of citrus bioflavonoids in a two-capsule serving, which puts two of the ingredients this article graded into one bottle. It is vegetarian and gluten-free, and the label reads two capsules one to three times daily. If you want the quercetin lead from this article in a bottle rather than in a lab report, this is where it lives.
The two vitamin C options are not interchangeable. C-RLA is the higher dose in a liposomal liquid, in a vanilla caramel flavor. The Integrative Therapeutics bottle carries the lower dose with quercetin and citrus bioflavonoids in capsules. Pick one rather than stacking them.
The bundle that applies to the line. Buy any 3 or more bottles of NET Remedies and save 10 percent, any 6 or more and save 15 percent, applied automatically at checkout.
And the limit that applies to all five. None of these is a substitute for care. If a scar or an adhesion is causing you pain, restricting your movement, or changing, the person to see is a licensed health care practitioner, not a sixth bottle.
Frequently Asked Questions
How long does it take for scar tissue to form, and how long does it take to fade?
Formation starts immediately. Inflammation after a wound begins within 24 hours and persists up to 2 weeks, and collagen is being laid down during that window. The tissue keeps being reworked long after the surface closes. There is no reliable timeline for fading, and the research does not establish one: the same reviews that measure collagen state plainly that the degree of normalization required "is not yet fully established."
Can you actually get rid of scar tissue, or does it just fade?
You cannot get rid of it, and a page that says otherwise is not being straight with you. What has formed is a permanent change in tissue architecture. What changes over time is how that tissue remodels, and how it looks and feels while it does. That remodeling is the part nutrition can support.
What vitamins help with scar healing?
The nutrients with real institutional consensus behind them are protein, vitamin C, vitamin A, zinc, and iron, along with enough calories. Cleveland Clinic calls zinc "critical to every phase of the wound-healing process" and describes iron as providing oxygen to the wound site. Vitamin A should come from food rather than from pills, because high supplemental doses can cause adverse effects.
Do proteolytic enzymes like serrapeptase or bromelain actually work on scar tissue?
The mechanism is well described. Bromelain promotes fibrinolysis and breaks down fibrin, which the literature describes as a key component of scar tissue. What is missing is strong human evidence. The most-cited systematic review of serratiopeptidase concluded that the evidence is "based on clinical studies which are of poor methodology," and no human trial of a proteolytic enzyme for scar tissue was located in this research. Choose one as recovery support, not as a targeted intervention.
What foods should I eat after surgery to heal faster?
Build meals around the nutrients above: protein sources, vitamin C sources, and vitamin A from food rather than from supplements. Cleveland Clinic's guidance is to get vitamin A "via meals rather than pills." Your own requirements depend on body mass, age, activity level, and the severity of the injury, so if you want numbers rather than food categories, ask a clinician.
What causes keloid or hypertrophic scars instead of flat ones?
This is not settled. In a 2025 review, patients with thermal injuries showed a 70 percent rate of hypertrophic scarring, which suggests the nature of the injury plays a large role. Beyond that kind of injury-specific pattern, the research does not yet explain why one person's scar stays flat and another's becomes raised.
Does vitamin E actually help scars?
Vitamin E appears in the research as a compound studied at the laboratory level for regulating immune response and gene expression related to structural proteins. That is laboratory work, not a human outcome. The 2024 scoping review of diet and scars states that it found "no clear evidence" for several of the supplements it examined, so vitamin E does not belong in the settled column.
How do you keep a scar from getting raised or itchy?
Itching is one of the most common complaints, and the research base on it is thin. One small, short study found that a one-week Solanaceae-free diet significantly reduced scar itching, which makes it an interesting lead rather than a protocol. Anything beyond that is a conversation with a clinician, not something a supplement label can settle.
