Most people have a scar somewhere, and most of the time scars fade into the background over the months after an injury or operation. Sometimes, though, a scar stays raised, red, itchy, or tight — or simply sits somewhere too visible to ignore. The good news is that scars can almost always be improved and made less noticeable. The honest part is that a scar can rarely be erased completely. This guide explains why scars form the way they do, what can be done about them without surgery, when scar revision surgery is worth considering, and what results are realistic.

Why do some scars look worse than others?

A scar is the body's natural repair after the skin is broken. As a wound heals, the body lays down new collagen to close the gap. When healing is smooth, the result is a flat, pale, fine line. Several things can tip healing towards a thicker or more noticeable scar: tension pulling on the wound edges, a wound over a joint or on the chest or shoulder, infection or delayed healing, and an individual tendency to scar heavily. Where the scar sits, how the wound was closed, and how the skin is cared for while it heals all influence the final appearance.

Types of scars

Not all scars behave the same way, and the treatment depends on which kind you have.

Fine-line and flat scars

The most common kind — a thin line that is often red at first and gradually fades. These usually need nothing more than time, sun protection, and simple scar care.

Hypertrophic scars

A is raised and often red, but stays within the boundary of the original wound. It commonly appears after burns or wounds under tension, and frequently improves gradually over one to two years.

Keloid scars

A grows beyond the edges of the original wound and does not tend to settle on its own. Keloids are more common on the chest, shoulders, and earlobes, and in people with darker skin. They can be itchy or tender, and they have a real tendency to come back after treatment — which is why they are managed differently.

Contracture scars

When a scar tightens and pulls on the surrounding skin, it forms a . If it crosses a joint, it can limit movement. Contractures are common after burns and are an area where reconstructive surgery makes a real functional difference.

Depressed (atrophic) scars

These sit below the level of the surrounding skin, leaving a dip or pit — often seen after acne or chickenpox. They are managed differently again, usually with resurfacing or filling techniques rather than surgery.

Treating scars without surgery

Many scars can be improved without an operation, and non-surgical measures are usually the sensible first step. International scar-management recommendations put simple, well-tolerated treatments first, escalating only if the scar does not respond.12
— applied as a gel or an adhesive sheet — is the most established first-line treatment for raised scars and is widely recommended both to help prevent problem scars and to soften and flatten existing ones.3
For raised, stubborn hypertrophic scars and keloids, a placed directly into the scar can help flatten and soften it and relieve itch. Other measures — pressure garments (especially after burns), scar massage, and careful sun protection while the scar matures — support the result. Laser treatment is increasingly used for the redness and texture of some scars, though how much it helps depends on the scar type.4

Scar revision surgery

When a scar remains a problem despite non-surgical measures — because it is too wide, too tight, or poorly positioned — scar revision surgery can improve it. The aim is not to remove the scar (any operation leaves a new one) but to replace a poor scar with a finer, better-positioned one that heals more discreetly.
The right technique depends on the scar. A simple, wide scar may be cut out and re-closed carefully to give a thinner line. A tight or awkwardly angled scar can be reshaped with a , which repositions the scar into a zig-zag to release tension and let it sit more naturally along the skin's lines. Larger scars, or contractures after burns, may need a skin graft or a local flap to bring in healthy tissue.

Keloids need a special approach

Keloids deserve a note of their own because surgery alone is often not enough — cutting out a keloid without further treatment frequently leads to it coming back, sometimes larger than before. For this reason keloids are usually managed with a combination of treatments, and surgical removal is typically paired with an add-on therapy such as steroid injections or, in selected cases, a course of radiotherapy after the operation to reduce the chance of recurrence.5

What to expect from treatment

Scars take time to settle, and patience is part of the treatment. A scar continues to change for many months — often a year or more — before it reaches its final appearance, so the result of any treatment should be judged over that timescale rather than in the first few weeks. Non-surgical treatments such as silicone are used consistently over weeks to months. After scar revision surgery, the new scar goes through the same maturing process, passing through a red, firmer phase before fading.6

Is scar treatment right for me?

Whether a scar is worth treating — and which approach fits best — depends on the type of scar, where it is, how long you have had it, what has already been tried, and what matters most to you, whether that is appearance, comfort, or movement. Some scars have an excellent outlook; others, particularly keloids, call for realistic expectations and a longer-term plan. The purpose of a consultation is to look at your scar, explain the honest range of what treatment can achieve, and agree a plan that suits you.

Booking a consultation

Scar assessment and treatment are available on a private basis at consultations in central Warsaw and in the Podkarpacie region (Rzeszów). It helps to bring a note of when and how the scar occurred and details of any previous treatment. A consultation is the starting point for a personalised scar-management plan.
