Best Treatments for Hypertrophic Scars Explained

A hypertrophic scar may be raised, red, firm, itchy or painful long after the wound itself has healed. For many patients, the concern is not purely cosmetic: a tight scar across a joint, neck, chest or abdomen can restrict movement, pull on surrounding skin and remain a constant source of discomfort. The best treatments for hypertrophic scars depend on the scar’s age, location, cause, thickness, symptoms and behaviour over time.

Hypertrophic scars are often described as scars that have produced too much collagen during healing. Unlike a keloid scar, they remain within the original boundary of the injury or incision. They can follow surgery, burns, trauma, acne, infection or piercings, and are particularly common in areas under tension, such as the shoulders, chest and jawline. A specialist assessment matters because a scar that appears similar on the surface may need a very different treatment plan.

What makes a hypertrophic scar difficult to treat?

Scar tissue changes over months and sometimes years. In its active phase, a hypertrophic scar may be highly vascular, inflamed and itchy. Later, it may become paler but remain thick, tethered or uneven in texture. Treatment has to address the feature causing the problem rather than applying a single solution to every raised scar.

For example, a fresh red scar may respond well to measures that reduce inflammation and blood supply, whereas a mature, tight burn scar may need laser remodelling or surgical release to restore movement. A raised surgical scar in an area of repeated tension may recur if the forces acting on it are not considered during revision.

The distinction between hypertrophic and keloid scarring is equally significant. Keloids extend beyond the original wound and have a higher tendency to recur after surgery. An experienced plastic surgeon or laser specialist can establish the diagnosis, assess skin quality and advise whether conservative care, procedural treatment or a combined approach offers the best prospect of improvement.

Best treatments for hypertrophic scars: a tailored approach

Silicone gel and silicone sheeting

Silicone is frequently a first-line treatment for suitable hypertrophic scars, particularly after an incision has fully healed. Gel is often practical for the face, mobile areas and irregular contours, while sheets can be useful on flatter surfaces. Consistent use may help reduce redness, thickness, itching and discomfort over time.

Silicone does not remove a scar immediately, and results rely on regular application over several months. It is most effective when used as part of a wider scar-management programme and should not be applied to open, infected or poorly healed wounds.

Pressure therapy and scar massage

Pressure garments are most often used in burn scar management and in selected larger scars where prolonged, carefully fitted compression is appropriate. They can help control oedema and support scar maturation, although adherence can be demanding and treatment needs supervision, particularly where skin is fragile or sensation is altered.

Massage may improve comfort and mobility in some scars, especially where there is mild tightness or adherence. It is not a substitute for specialist treatment of a thick, symptomatic scar, and overly vigorous massage can irritate an active scar. Patients should be shown an appropriate technique by their treating team.

Intralesional injections

For a scar that remains raised, itchy or painful, intralesional corticosteroid injections are an established option. The medication is placed directly into the scar to reduce excessive collagen activity and inflammation. Treatments are commonly spaced several weeks apart, allowing the response and any adverse effects to be reviewed between sessions.

Steroid injections can flatten and soften many hypertrophic scars, but dosing and placement require judgement. Excess treatment may cause thinning, altered pigmentation or visible small blood vessels in the surrounding skin. In resistant cases, a specialist may consider combination injections, such as corticosteroid with another anti-scarring medicine, where clinically appropriate.

Vascular and resurfacing laser treatment

Laser treatment can be particularly valuable when a scar remains red, thick, itchy or texturally irregular. Vascular lasers target the abnormal blood vessels that contribute to redness and activity in an early hypertrophic scar. Fractional ablative lasers create controlled microscopic treatment columns within the scar, encouraging remodelling and improving pliability, surface texture and, in selected cases, functional restriction.

The right laser, settings and treatment interval are determined by the scar and the patient, not by a generic package of sessions. Skin type, pigment risk, scar thickness, previous treatments and the possibility of post-inflammatory pigmentation must all be considered. For complex burn scars, traumatic scars or scars following reconstructive surgery, consultant-led laser care provides the advantage of integrating laser treatment with surgical planning and rehabilitation.

Laser treatment is rarely a one-visit solution. Improvements are gradual and commonly require a planned course, with photographs and clinical assessment used to measure change. Temporary redness, swelling, crusting or pigment alteration can occur, and aftercare is central to a safe outcome.

Surgical scar revision

Surgery may be the best option when a hypertrophic scar is broad, poorly aligned, tethered to deeper tissue or restricting movement. A scar revision can remove or rearrange problematic tissue, release contracture and reposition the scar along more favourable lines. In some areas, techniques such as local flaps or Z-plasty may reduce tension and improve function.

However, excision alone is not automatically the answer for a scar-prone patient. Any new incision has the potential to form another hypertrophic scar. Surgical revision should therefore be planned with prevention in mind, which may include meticulous closure, silicone therapy, carefully timed injections or laser treatment during the healing period. When the scar affects function, surgical decision-making should prioritise movement, comfort and durable tissue quality alongside appearance.

When combination treatment is better

The most successful scar programmes often combine treatments rather than relying on one intervention. A patient might begin with silicone and scar care after wound healing, proceed to injections for persistent thickness, then have laser treatment for residual redness and texture. A contracted scar may need surgical release first, followed by laser remodelling and rehabilitation.

This staged approach is particularly relevant after burns, major trauma and complex surgery, where scars can involve changes in skin colour, thickness, sensation and movement at the same time. It also allows treatment to be adjusted as the scar matures. A scar that looks alarming at three months may settle substantially with conservative care, while one that remains active or restrictive deserves earlier escalation.

Choosing the right specialist

Patients should seek assessment sooner if a scar is rapidly thickening, increasingly painful, repeatedly breaking down, limiting movement or causing significant distress. These symptoms do not always mean that urgent intervention is required, but they warrant proper evaluation.

A consultant plastic surgeon with advanced laser expertise can assess whether the scar is hypertrophic, keloid or affected by another process, and whether treatment should be non-invasive, surgical or combined. This is especially relevant for scars on the face, chest, joints and hands, for scars after burns or cancer surgery, and for patients with a history of difficult healing or pigment change.

At Skin Surgeon, scar treatment planning is consultant-led and based on the biology and functional effect of the individual scar. This provides a clear route for patients who need more than a standard aesthetic procedure, including access to reconstructive judgement alongside advanced therapeutic laser options.

No responsible clinician can promise that a scar will disappear completely. The realistic aim is a scar that is flatter, softer, less symptomatic, more mobile and less visually prominent. With the right timing and specialist plan, even a longstanding hypertrophic scar can often become far less intrusive in daily life.
