What are you dealing with?

Treatment choice depends more on location and age of scar than anything else. Tap the spot that matches yours — or pick from the list — to jump to the protocol stack I’d start with.

Treatments at a glance

Non-invasive vs invasive treatments.

Nine treatments compared across the five dimensions that actually shape your decision: evidence strength, type, cost, risk, and discomfort.

Evidence strengthResearch quality, not effectiveness.
  • StrongMultiple RCTs or meta-analyses
  • ModerateSome controlled studies, consensus forming
  • EmergingEarly studies, promising but thin
  • LimitedCase reports, low-quality data

Red light therapy · the research

Not one light. Four — reaching four depths.

Keloids live in the collagen layer, 1–4 mm down. The wavelengths that reach it are the ones that matter. Everything else is marketing.

Fig. 01 — Anatomy
Cross-section of skin showing an LED panel above, with red and near-infrared beams reaching the dermis. A keloid sits raised on the surface.

Cytochrome c oxidase absorbs photons in mitochondria. Down-regulates TGF-β1, the main driver of excess collagen in keloids.

Why ScarInsight

About this site

I started ScarInsight because my family has lived with keloids across three generations, and the information I needed kept arriving too late or dressed up as marketing. I wanted one place that treats the evidence the way a researcher would and the reader the way a friend would.

My standard is simple. I grade every treatment by the quality of the studies behind it, not the confidence of the people selling it. Emerging options get flagged as emerging. Strong options get the citations to back it up.

This site is not a substitute for a dermatologist. It is a research layer you can bring into that conversation so you walk in knowing what to ask.
