How a scar matures, why it looks worse in the second month, which treatments have a proven effect and which are a waste of money.
A scar is unavoidable. Every incision through the skin leaves a mark, and no technique, cream or laser removes it completely. What can be influenced is how wide, how raised and how noticeable it will be.
The final appearance depends on several things at once: the surgical technique and the tension on the wound, the area of the body, whether there was an infection, your individual biology, and how the scar is cared for during the first year. The first two are in the surgeon’s hands; the last is in yours.
How the scar matures
- Weeks 1–3. The wound has closed and the scar is thin and pale. Many people assume that is the end of it
- Months 1–3. The scar becomes red, raised and firm. This is alarming, but it is the normal phase of collagen remodelling
- Months 3–6. The scar begins to fade and flatten
- Months 6–18. Slow maturation to its final appearance
What has a proven effect
Silicone gels and sheets. These have the strongest support in the medical literature for immature scars. They work through occlusion (sealing the surface) and by keeping the scar hydrated.
The condition is dull but decisive: start as soon as the wound has fully closed and apply it every day for at least three months. Two weeks of use achieves nothing.
Sun protection. The cheapest and most underrated measure. Ultraviolet light stimulates pigmentation in an immature scar, and the darkening is long-lasting. Twelve months of full protection — SPF 50, clothing or a plaster.
Compression. For burns and large areas, compression garments are standard. They are worn for a long time — months — and the difference shows.
Massage. Once the wound has fully healed, gentle and sustained. It helps stop the scar adhering to the underlying tissue.
Corticosteroid injections. For hypertrophic and keloid scars. They are given as a course by a doctor, not self-administered.
What does not work
The market for scar creams is large, and most of its promises do not stand up to scrutiny.
- Vitamin E on a scar — there is no convincing evidence, and in some people it causes irritation
- “Natural” oils and extracts with bold claims but no ingredient with a proven mechanism of action
- Anything that promises to make the scar “disappear”. It does not disappear
- Early massage of a wound that has not closed — this is harmful
- Picking off the scab so the wound “heals faster”
Why some scars heal poorly
Not everything comes down to technique. The same hands produce different scars in different people and in different parts of the body.
- Location. The face heals well. The chest, shoulders and back heal poorly, with a tendency for scars to thicken
- Tension. A scar that is stretched by movement widens
- Smoking. It constricts small blood vessels and directly impairs healing
- Individual tendency. Some people form keloids, and that does not change
When scar revision is considered
For planned surgical scar revision, the rule is to wait for the scar to mature — usually about twelve months. The scar changes on its own over that year and often looks noticeably better without any intervention. That does not mean waiting in silence, though: a scar that becomes raised, painful or itchy, or restricts movement, is assessed early — as early as the fourth to eighth week — because where there is a risk of abnormal scarring, early treatment works better than late treatment. It is the surgery that waits, not the treatment.
Revision is justified when the scar is wide, uneven or lies in an unfavourable direction, or when it restricts movement in a joint — the last of these is a functional rather than a cosmetic problem.
The realistic expectation is improvement, not disappearance. The new scar will also go through the same year of maturation.
In short
Silicone every day for three months, full sun protection for a whole year, gentle massage of the skin, and patience until the twelfth month. Four things that cost next to nothing and do more than any cream with promises on the label.
