In short. Why most scar treatment waits for maturation, what is done during the wait, and the findings that should not wait at all.
Key points
- A patient who is told to wait and given nothing to do has been told half of the plan.
- The measures used during maturation are active treatment, they start early, and they are why the period before a decision can be made is not wasted.
Waiting is the hardest advice to accept about a scar, because it sounds like doing nothing. It is not. Waiting is a decision with a reason: a scar that is still maturing is a target that moves, and treatment aimed at a moving target cannot be judged.
Why most treatment waits
A scar is still organising itself for twelve to eighteen months. Treatment applied at three months is applied to tissue that would have changed on its own, so what the treatment achieved cannot be separated from what time would have done anyway. This is not a refusal to treat; it is a decision about when treatment will be worth having.
What happens during the wait
Silicone, in gel or sheet form, is used during maturation. Pressure is used where the site suits it. Sun protection is used throughout. A joint that a scar crosses is kept moving. Where a scar is already growing beyond its margins, or is keloid in behaviour, measures aimed at stopping that are started rather than deferred. What is deferred is the plan that depends on the scar being stable: surgical revision, and treatment aimed at colour and texture.
The wait is not inaction
A patient who is told to wait and given nothing to do has been told half of the plan. The measures used during maturation are active treatment, they start early, and they are why the period before a decision can be made is not wasted.
What should not wait
Four things override the timetable. A wound that has opened needs attention now, because an open wound is not a scar problem. An infection needs care now, because it moves quickly and adds the inflammation that builds scars. A scar that is restricting a joint, or pulling on an eyelid or a lip, is treated earlier because function is at stake; a contracture is far easier to prevent than to correct. And a scar growing beyond its original margins is assessed rather than observed, because it may not be a scar that will settle at all.
What treatment after maturation can do
For a scar that has settled and is still troublesome, the options are aimed at particular qualities rather than at the scar as a whole: an injection into a raised, firm scar, treatment aimed at colour and texture, and dressings for a scar that is tight or uncomfortable. Each of these can often improve a scar. None removes one, and firmness, colour and texture seldom all change together.
Some scars need no treatment at all. A raised scar that is comfortable, stable and in a place the patient does not mind can be left alone.
Do not wait for these
- A wound that has opened, or an area that is discharging, hot or swollen — seek care the same day.
- A scar restricting a joint, or pulling on an eyelid or a lip — prompt assessment.
- A scar still growing beyond the original wound, or a lump within it that is enlarging.
Frequently asked questions
How long should I wait before treating a scar?
For most scars, until maturation is over, which is twelve to eighteen months. The reason is that a scar that is still changing is a target that moves, so what a treatment achieved cannot be separated from what time would have done anyway. Where a scar is restricting movement or growing beyond its margins, that timetable does not apply.
What can be done for a scar during the waiting period?
More than the word waiting suggests. Silicone in gel or sheet form, pressure where the site suits it, protection from the sun, keeping the skin supple, and keeping a joint moving when the scar crosses it are all active treatment, and they are started early because they work with the healing rather than against it.
Is there a scar that needs no treatment at all?
Yes, and saying so is a legitimate outcome of an assessment. A raised scar that is comfortable, stable and in a place the patient does not mind can be left alone. Treatment is offered where a scar is troublesome in a way that can realistically be improved, not because a scar exists.
Risks & Limitations
- A scar is permanent. Maturation changes its colour, height and firmness over twelve to eighteen months, not its existence.
- A raised scar is usually uncomfortable rather than dangerous, which is why the small number of findings that are dangerous are named individually.
- Maturation is slow, and a scar often looks worse at six weeks than it will at six months; judging it early means judging a moving target.
- Treatment can improve a scar but cannot remove it, and a further operation trades one scar for another arrangement rather than undoing the first.
- A keloid grows beyond the original wound, does not settle on its own, and tends to recur after it is removed.
When to Seek Care
- A scar growing beyond the edges of the original wound, or a lump within it that is enlarging — have it assessed within days.
- Redness with heat, swelling or discharge in the scar, or a fever — seek care the same day.
- A wound that has opened, or a gap appearing along the scar — seek care the same day.
- A scar tightening across a joint, or pulling on an eyelid or a lip — prompt assessment.
- A scar that has started to bleed or ulcerate — urgent assessment.
