When Can You Treat a Scar After Surgery or Injury?

Why timing matters, how to tell if your scar is ready, and why older scars are not too late.

One of the first questions we hear is about timing: "My surgery was four months ago. Can I start?" The honest answer depends on whether the scar has finished healing, and that takes longer than most people expect.

Scars keep changing for months

When the skin closes, the healing is not over. Underneath, the body keeps building and reorganizing collagen in the scar for many months. During that time a scar often looks pink or red, may feel firm or tender, and can change in color and texture from week to week. Treating a scar in that phase means working on a moving target.

For most people a scar is fully healed 6 to 12 months after the surgery or injury. Larger scars and surgical scars often take toward the longer end.

How to tell if your scar is ready

  • It is no longer pink or red, and its color has stopped changing
  • It is not tender, itchy, or sore
  • It has looked the same for the last few months
  • It sits flat or indented, not raised

If you are not sure, that is what the free consultation is for. We look at the scar on video and tell you honestly whether to start now or wait. Sometimes the right answer is "come back in three months," and we would rather say that than treat too early.

Is an old scar too late?

No. A scar that is several years or even decades old is fully healed, and that is exactly when inkless scar revision works on it. The treatment triggers new collagen and elastin inside the scar, and your skin can still do that no matter how old the scar is.

Scars we do not treat

We do not treat raised (hypertrophic) or keloid scars, scars on the face, or any scar that is not fully healed. If you have a history of keloid scarring, tell us before you book.

What to expect once you start

How many sessions will it take? There is no honest fixed number, because the result comes from your own skin. Some people see a visible change after their first session, while others need a few before it starts to show. Healing between sessions takes 6 to 8 weeks on average, and we judge each result only after that window.

Scar sessions are priced by size: small $200+, medium $300+, and large $450+ per session. See our scar pricing for details.
