How Scar-Healing.com works
What the four evidence ratings mean
Every treatment on this site carries one of four ratings, shown next to the treatment name, not buried in the text.
Strong
Multiple randomized trials or meta-analyses agree on both the direction and the rough size of the effect.
Moderate
Limited trials, or consistent observational data without randomized confirmation.
Limited
Small, short or single studies. A signal exists, and there is not enough of it to rely on.
Weak
Tested and found wanting: anecdotal, mixed or negative evidence.
Weak means tested with results that went against the treatment. How a rating is decided is set out in the editorial and citation policy.
The five commitments
- 01 Every claim carries a citationThe primary source, named.
- 02 Every citation is a live linkOpen it and check the source.
- 03 Evidence is graded Strong, Moderate, Limited or WeakGrades move in either direction as evidence changes.
- 04 Errors get correctedOn the page itself, with the revision date updated to the day of the change. Report an error →
- 05 No sponsored contentNo product placement, no affiliate links, no paid rankings.
How we use AI
We use AI to source and verify the clinical studies and data behind our articles. We also use AI to create text, but there is always a human review in the publishing workflow. No article is published without it.
AI sources and verifies
Searches the literature, pulls the studies, and checks that each citation resolves to the paper it names.
AI drafts
Produces the first version of the text from those verified sources.
A human reviews and publishes
Every article is read and checked by a person before it goes live. Nothing publishes without this step.
How this site works
Every claim is cited
Each statement traces to a named source, and every reference is a live link you can open and check yourself.
Evidence is graded
Every treatment is rated Strong, Moderate, Limited or Weak for the strength of the research behind it.
Continuously updated
Articles are revisited when new research is published. There is no fixed content refresh schedule. Each page shows the date it was last reviewed.
Independent
No products, no sponsors, no affiliate links. Nothing on this site earns money from a treatment being recommended.
What we cite
Evidence comes first from peer-reviewed clinical research and primary literature. Where trials do not exist, we use specialist association guidance and established clinical references, and we say which one we are relying on. Consumer health sites are not treated as evidence.
The sources we cite most often:
Names are listed to show where the evidence comes from. Scar-Healing.com is not affiliated with, endorsed by, or sponsored by any of them.
What you will find here
Every scar type and every treatment has its own guide. Each opens with a one-line answer, then the facts, a graded treatment table, what you can do at home, and when to see a doctor. Longer explainers live under Learn. Each takes one question and answers it in full: how a wound becomes a scar, or why collagen keeps remodeling for months after the skin looks closed. The guides give the verdict. The explainers give the reasoning behind it, and the two link to each other throughout.
How a page stays current
Scar research moves, and a claim that was fair two years ago can be out of date by the time you read it. Pages carry the date they were last checked against the literature. The recheck searches for new studies on the same question, tests whether the evidence grade still matches, and confirms every citation still resolves and has not been retracted. When a grade moves, the page changes. When nothing has moved, the date still resets, because the check happened.
Who this is for
A fresh wound from an operation, a burn or a delivery, where care in the first weeks changes the outcome. A scar that has been there for years, a keloid, acne pits, a pale line, where the question is whether anything can still be done. Or a treatment someone has quoted you, where the question is whether it is worth the cost and the downtime. The pages are written for those three situations, and they start with the answer. No medical background is assumed. A technical term that earns its place gets explained once, in plain words, and where the evidence for a treatment is weak, the page says weak.
Disclosure
Scar-Healing.com is an independent resource dedicated to the science of scar formation. It is not affiliated with, endorsed by, or sponsored by any of the institutions, journals or databases whose research it cites. There is no sponsored content, no product placement, and no affiliate revenue anywhere on this site. Nothing here earns money from a treatment being recommended.
Common questions
The site is written and maintained by its editorial team, working from the published literature. Pages carry an editorial byline because a page is the product of several passes: sourcing, drafting, checking and a later recheck. The AI policy page sets out which parts of that workflow use AI and where the human step sits.
No. There is no store, no booking, no paid placement and no sponsored content. The prices you see are published cost ranges, included so you can sanity check a quote you have been given. They are not offers, and nobody pays to appear in a table here.
Because it is. A grade describes how much good research supports a treatment, not how popular the treatment is. Vitamin E is well known and poorly supported. Silicone is unglamorous and the best supported topical available. Grading records that difference.
