- Scar revision is a range of treatments to make a scar less noticeable.
- Options run from creams, silicone and laser to steroid injections and surgery.
- The best approach depends on the scar type — flat, raised, keloid, sunken or contracted.
- Scars can be improved but rarely removed completely.
What scar revision is
Scar revision is not a single procedure but a range of treatments used to improve how a scar looks or feels, or to ease symptoms such as tightness, itch or discomfort. A scar forms as part of normal healing, and every wound that reaches a certain depth leaves one. The aim of treatment is usually to make a scar less noticeable — flatter, paler, smoother or more comfortable — rather than to remove it. This is an important point to hold on to from the start: scars can very rarely be erased completely, so realistic expectations matter and are part of a good consultation. For many people, a scar that once drew the eye can be softened enough that it no longer bothers them, and symptoms such as pulling or itch can be settled.
Types of scars in plain terms
Scars behave differently depending on how they formed and how the skin healed, and describing them in plain terms helps in choosing treatment. Flat, pale scars are the most common and often need little more than time and good skin care. Stretched scars are flat but widened, sometimes where a wound was under tension while healing. Sunken or “pitted” scars sit below the surrounding skin — some acne scars are a familiar example — because tissue was lost during healing. Raised scars stand above the skin, and here two kinds are worth separating: hypertrophic scars stay within the boundary of the original wound, while keloids grow beyond it into surrounding skin. Raised and keloid scars are especially relevant for the darker and Asian skin tones common in Singapore, which can be more prone to keloids. Some scars also tighten across a joint or crease (contractures) and can limit movement.
How scars are assessed
Because treatment is matched to the scar, assessment comes first. A dermatologist or plastic surgeon will look at the type of scar, its age (whether it is still settling or long established), its location on the body, and any symptoms such as itch, pain, tightness or restricted movement. The person’s own goals matter just as much — some people are troubled mainly by colour, others by a raised lump, a sunken hollow, or a scar that pulls. Skin tone and any tendency to form keloids are noted, as these shape both the choice of treatment and the caution needed. Understanding what is realistic for a particular scar, and what the person hopes for, is what allows a sensible plan to be made.
Treatment options matched to scar type
Once the scar is understood, treatment is chosen to suit it, and it is common to combine approaches and to need more than one session. Non-surgical options form the mainstay for many scars. Silicone gels or sheets are widely used to help flatten and soften raised scars and settle redness. Pressure therapy can help some scars, and gentle massage is often encouraged. Steroid injections are a key treatment for raised and keloid scars, helping to flatten and soften them over a series of sessions. Laser treatments can address colour, such as redness, as well as texture, and are useful for many flat or discoloured scars. Microneedling or resurfacing, and techniques such as subcision, can improve some depressed acne scars, while fillers may temporarily lift a sunken scar so it sits level with the skin around it.
Surgical scar revision has its place too. Surgery can reposition a scar so it follows natural skin lines or creases, re-close a wide or uneven scar more neatly, or release a contracture that is limiting movement. It is often reserved for scars that are unlikely to improve enough by other means. For keloids in particular, surgery is generally combined with other treatments rather than used alone. In practice, a plan often layers several of these methods over time — for example silicone and injections for a raised scar, or resurfacing followed by maintenance care for acne scarring.
Timing of treatment
Timing is one of the least obvious but most useful parts of scar management. Many scars improve naturally over many months as they mature, fading in colour and flattening on their own, so treatment is sometimes best delayed to see how a scar settles rather than acting on it while it is still red and firm. Jumping in too early can mean treating a scar that would have improved by itself. At the other end, early care of a healing wound can genuinely reduce eventual scarring — keeping the wound clean, protecting it, avoiding tension where possible and following wound-care advice all help. So timing works in two directions: gentle, sensible care early, and patience before deciding on active revision.
A note of caution about keloids
Keloids deserve particular care because they can recur or even worsen after treatment, including after surgery. This is why they need careful, specialist management rather than a quick fix, and why treatment is usually built from a combination of measures and followed up over time. If you are prone to keloids, it is worth mentioning this before any procedure — including cosmetic ones — that breaks the skin, as it may change what is advisable. A dermatologist or plastic surgeon experienced with keloid-prone skin is well placed to guide this.
What to expect and aftercare
Scar treatment is usually a process rather than a single event, and results build gradually over weeks and months. Aftercare is part of the outcome. Sun protection is important, as scars can darken with sun exposure and become more noticeable; keeping a healing or treated scar covered or protected helps. Following the provider’s plan — using silicone or other measures as advised, attending review or repeat sessions, and caring for the skin gently — gives the best chance of improvement. Some treatments cause temporary redness or sensitivity that settles, and your provider will explain what is normal for the approach chosen.
Realistic expectations
The honest message running through scar revision is improvement, not perfection. A good result makes a scar flatter, paler, smoother or more comfortable and less likely to catch the eye — but the scar is usually still there on close inspection. Setting this expectation early tends to lead to greater satisfaction, because the goal is agreed from the start. Combining treatments and allowing time generally gives more than any single quick measure.
Prevention and good wound care
Not all scarring can be prevented, but sensible wound care can influence how a scar turns out. Keep wounds clean, protect them from the sun while they heal, avoid picking at scabs, and follow any dressing or aftercare instructions. Where the skin is under tension, following advice on support and protection can help. For those who scar easily or form keloids, raising this early lets a clinician plan ahead.
When to see a doctor
See a doctor if a scar is raised, itchy or painful, growing (a possible keloid), restricting movement, or simply bothering you, so the most suitable treatment plan can be tailored to it. Seek review sooner for a scar that is growing, painful, or shows signs of infection such as increasing redness, warmth, swelling or discharge. And bear in mind that a changing or non-healing skin lesion should be assessed by a doctor rather than assumed to be a scar — not everything that looks like a scar is one. Any assessment or treatment should be carried out by a suitably qualified dermatologist or plastic surgeon at a licensed facility.

Common questions
Can a scar be removed completely?
Scars can usually be made much less noticeable but rarely removed entirely; the goal is improvement.
How are keloid scars treated?
Often with steroid injections, silicone and other measures; surgery alone tends to recur, so it is combined with additional treatment.
Which is better — laser or surgery?
It depends on the scar; flat, discoloured scars often suit lasers, while wide or contracted scars may need surgical revision.
