In short. A scar is often at its worst at six weeks and looks nothing like that a year later. What happens in each phase, and why the early look is not the final one.
Key points
- The appearance at six weeks is the peak of the rebuilding phase rather than the finished scar.
- A scar judged at that point and treated on that basis is being judged in the middle of a process that continues for another year.
- This is why the honest first answer for most scars is time.
A fresh surgical scar is red, raised, firm and often itchy. It may be tender, and the skin around it may feel numb. It is usually at its most conspicuous some weeks after the operation rather than immediately, and it looks worse at six weeks than it did at two. None of that is deterioration. A scar is a structure being rebuilt, and the rebuilding takes a year or more.
The first two weeks: closing the wound
The wound is sealed by a clot and then by new tissue laid down quickly. The scar at this stage is fragile, the surrounding skin is swollen, and the priority is keeping the wound clean and closed. Sutures or clips are removed according to the plan your team gave you. Pain and swelling should be settling by the end of this period; if they are increasing, that is a different conversation.
Weeks two to six: the phase that looks worst
The scar becomes red, raised and firm as new collagen is laid down in quantity and in a disorganised pattern. Itching is common. A scar can be quite prominent, and this is the point at which patients most often become concerned that something has gone wrong. It has not. The tissue being produced now will be remodelled later.
Six weeks is the worst point, not the result
The appearance at six weeks is the peak of the rebuilding phase rather than the finished scar. A scar judged at that point and treated on that basis is being judged in the middle of a process that continues for another year. This is why the honest first answer for most scars is time.
Months two to twelve: remodelling
The disorganised collagen is gradually reorganised, blood vessels within the scar diminish, and the scar becomes flatter, paler, softer and less sensitive. The change is slow and is best judged from photographs taken months apart rather than from memory. Sensitivity to sun persists, and a maturing scar burns more easily than the skin around it.
What is expected and what is not
Red, raised, firm, itchy and slightly tight are all expected in the first months. Growing beyond the boundary of the original wound is not. Becoming increasingly painful months after healing is not. Opening, discharging or spreading redness is not. Those findings are assessed when they appear rather than at the end of the year, and they are the reason a scar is reviewed rather than simply waited out.
What helps maturation
Keeping the wound clean while it is healing, protecting the scar from the sun once it has closed, not picking at it or scrubbing it, and attending the reviews your team planned. What does not help is applying products to an open wound, testing the scar by stretching it, or judging the result at six weeks.
Seek care rather than waiting if
- The wound becomes more painful, spreads red, feels hot or swollen, discharges pus, or you develop a fever — contact your treating team now, and if the team cannot be reached go to the nearest emergency department.
- The wound opens, gapes or separates, or fluid comes from it.
- The scar grows beyond the original wound, or becomes increasingly painful or itchy months after healing.
Frequently asked questions
Why does my scar look worse now than it did at two weeks?
Because the scar is being rebuilt. The inflammatory and proliferative phases peak in the first weeks, which is when a scar is reddest, firmest and most raised. It typically looks worse at around six weeks than it did at two, and then improves steadily over the following year.
How long until a scar is fully mature?
Twelve months or more is the usual range, and some scars take longer. Maturation involves the scar becoming flatter, paler, softer and less sensitive. Nothing needs to be done to make that happen, and judging the result before it has occurred is unreliable.
Will the numbness around my scar go away?
The altered or numb feeling around a scar is caused by small nerves being divided when the wound was made. It commonly improves over months and often returns partially rather than completely. It is expected rather than a complication.
Risks & Limitations
- Every operation leaves a scar. A scar is a normal result of healing, not a complication.
- A scar continues to change for twelve months or more, so its early appearance is not its final appearance.
- Hypertrophic scarring and keloid, in which a scar becomes raised, thickened, itchy or continues to grow.
- Infection, wound breakdown or a collection under the wound, any of which changes how a scar forms.
- Scar contracture, where a scar tightens and restricts movement or distorts a nearby structure.
- No treatment removes a scar. Treatment can change its width, height, colour, texture or tightness.
- Further surgery produces a new scar, which may heal better or worse than the one it replaced.
When to Seek Care
- Increasing pain, spreading redness, heat, swelling, pus or a fever from a wound — contact your treating team now, and if the team cannot be reached go to the nearest emergency department.
- A wound that opens, gapes or discharges fluid.
- A scar that keeps growing beyond the original wound, or that becomes painful or itchy months after healing.
- A scar that tightens and restricts movement, or that distorts a nearby feature.
- Breathlessness, chest pain or a swollen painful calf — seek emergency care immediately.
