What Is a Hypertrophic Scar?

A hypertrophic scar is a type of raised scar that develops as an abnormal response to the body's natural healing process. When skin is injured, whether from surgery, a burn, or trauma, the body produces collagen to repair the damage. In some cases, the body produces an excessive amount of collagen, which leads to a scar that is thick, raised, and firm. These scars are often red or pink in appearance and can be itchy or even painful. They are most commonly found in areas where the skin is taut, such as the chest, back, shoulders, and upper arms.

It is crucial to distinguish a hypertrophic scar from a keloid scar, as they are often confused but require different management strategies. The defining feature of a hypertrophic scar is that it remains within the boundaries of the original wound. In contrast, a keloid scar is more aggressive, growing beyond the initial injury site and encroaching on healthy surrounding skin. Hypertrophic scars often develop within weeks of an injury and may improve on their own, typically flattening and becoming paler over a period of one to two years. However, for many individuals, the appearance, discomfort, and potential restriction of movement, especially over a joint, make seeking elevated scar correction a priority for both physical comfort and self-confidence.

As a Consultant Plastic Surgeon, my approach to raised scar treatment is grounded in a thorough diagnosis to confirm the scar type. This ensures that any recommended hypertrophic scar revision plan is tailored specifically to your needs, aiming for a result that is not only aesthetically improved but also provides relief from physical symptoms. Understanding the nature of your scar is the first and most critical step toward effective treatment.

Understanding Why Raised Scars Form

The formation of a hypertrophic scar is fundamentally a result of an overzealous healing response. When the deeper layer of the skin, the dermis, is damaged, the body initiates a complex three-phase healing process: inflammation, proliferation, and remodelling. Hypertrophic scars occur when there is an imbalance in this process, specifically an overproduction of collagen during the proliferation phase. This excess collagen, composed of thick, disorganized fibres, accumulates within the wound boundary, creating the characteristic raised and rigid texture of a hypertrophic scar.

Several factors can increase the likelihood of developing this type of raised scar tissue. Wounds in areas of high skin tension, such as across joints or on the chest and shoulders, are particularly susceptible. The constant pulling and movement can stimulate the fibroblasts—the cells responsible for producing collagen—to remain in an overactive state. Furthermore, prolonged inflammation is a key trigger; wounds that take longer than three weeks to heal due to factors like infection or poor blood supply are at a higher risk of abnormal scarring. The depth and severity of the initial injury also play a significant role. Deeper wounds, such as second and third-degree burns, inherently require a more robust collagen response to heal, thereby increasing the risk of hypertrophic scar development.

While anyone can develop a hypertrophic scar, some individuals may have a genetic predisposition that makes them more prone to this type of scarring. Understanding these contributing factors is essential in both preventing and treating raised scars. For patients in Hertfordshire, Stevenage, and London seeking scar tissue reduction, a detailed consultation helps to identify any underlying causes, which informs the most effective strategy for scar flattening and management.

Non-Surgical Options for Scar Flattening

Before considering surgical intervention, it is important to explore the range of effective non-surgical options available for scar flattening. For many patients, these methods can significantly improve the height, texture, and colour of hypertrophic scars, offering a less invasive path to elevated scar correction. A patient-centric approach involves assessing the scar’s age, location, and symptoms to determine the most suitable starting point.

One of the most common and effective first-line treatments is the use of silicone gel sheets or ointments. When applied consistently over several months, silicone therapy helps to hydrate the scar tissue, reduce collagen overproduction, and can lead to a softer, flatter, and less red appearance. Another well-established treatment involves intralesional corticosteroid injections. A steroid, such as triamcinolone, is injected directly into the scar tissue at regular intervals. This works by reducing inflammation and inhibiting the activity of fibroblasts, thereby breaking down excess collagen and helping to flatten the scar. Steroid injections are particularly effective for itchy or painful scars.

For more persistent or prominent scars, advanced therapies like laser treatment can be highly beneficial. Vascular lasers, such as the Pulsed-Dye Laser (PDL), target the blood vessels within the scar, reducing redness and helping to remodel the underlying collagen. Ablative fractional lasers can also be used to create microscopic channels in the scar tissue, stimulating a more controlled healing response that improves texture and flexibility. Other options include pressure therapy, which involves wearing custom-made garments to apply constant pressure to the scar, and cryotherapy, which uses liquid nitrogen to freeze and destroy excess scar tissue. Often, a combination of these non-surgical treatments yields the best results for scar reduction.

Is Hypertrophic Scar Surgery Right for You?

While non-surgical treatments can be very effective, there are instances where hypertrophic scar surgery becomes the most appropriate and beneficial option. The decision to proceed with a surgical approach, known as hypertrophic scar excision, is made in partnership between you and your surgeon after a comprehensive evaluation. It is typically considered when conservative treatments have failed to produce the desired improvement, or when the scar causes significant functional impairment or emotional distress.

An ideal candidate for raised scar treatment through surgery is someone with a mature hypertrophic scar—one that has stopped actively growing or changing—that is causing specific problems. This might include a scar that restricts movement because it is located over a joint (a contracture), causes persistent pain or discomfort, or is in a highly visible area and significantly impacts self-confidence. It is also important that the patient has realistic expectations. The goal of surgery is not to erase the scar completely, but to replace it with a new, less conspicuous scar that heals in a much more controlled and aesthetically pleasing way.

As a board-certified Consultant Plastic Surgeon in the UK, my primary focus is on patient safety and achieving natural, balanced results. During a consultation at my practice, which serves patients from London, Hertfordshire, and surrounding areas, we will discuss your concerns in detail. We will review the history of your scar, what treatments you have tried, and your ultimate goals. Critically, we will also assess the factors that may have contributed to the initial hypertrophic scarring. This allows us to plan a surgical procedure that not only removes the problematic tissue but also incorporates techniques to minimise the risk of recurrence, such as redirecting tension lines in the skin. Surgery is often combined with post-operative non-surgical therapies, like steroid injections or silicone sheeting, to optimise the final outcome.

Your Raised Scar Treatment Journey

Embarking on a journey towards hypertrophic scar revision begins with a detailed and collaborative consultation. This initial meeting is fundamental to building a trusted partnership and establishing clear, realistic goals. During this session, I will carefully examine the scar, noting its size, location, and the tension of the surrounding skin. We will have an open discussion about your medical history, the scar's origin, and how it impacts your daily life, both physically and emotionally. This is your opportunity to ask questions and gain a full understanding of the options available for your specific case. Together, we will formulate a bespoke treatment plan that aligns with my philosophy of creating natural and well-proportioned results.

Should hypertrophic scar surgery be the chosen path, the procedure itself is typically performed as a day case under local anaesthetic, though this can vary depending on the scar's complexity. The primary surgical technique is called scar excision. This involves carefully cutting out the entirety of the raised, fibrous scar tissue. The key to a successful revision lies not just in the removal, but in the meticulous closure of the new wound. I employ specialised plastic surgery techniques to minimise tension on the new incision, often using layered sutures beneath the skin to provide strength and support during healing. This precise approach is designed to create the optimal conditions for a finer, flatter, and less noticeable scar to form.

In some cases, more advanced techniques may be required. For instance, a Z-plasty is a method where small, triangular flaps of skin are repositioned to change the direction of the scar. This can be particularly effective for scars that cross natural skin creases or cause tightness, as it helps to break up the straight line of the scar and release tension, making it less visible and improving mobility. The entire surgical plan is tailored to you, ensuring the technique used provides the best possible foundation for healing and an improved aesthetic outcome.

Recovery After Hypertrophic Scar Revision

The recovery period following hypertrophic scar revision is a critical phase that significantly influences the final appearance of the new scar. Adherence to post-operative instructions is paramount to ensure optimal healing. Immediately after the procedure, you can expect some localised swelling, bruising, and mild discomfort in the treated area, which is a normal part of the initial healing phase and typically subsides within one to two weeks. Pain is usually minimal and can be managed effectively with standard pain relief medication.

You will leave the clinic with a dressing over the new incision, and you will be given specific instructions on how to care for the wound, which includes keeping it clean and dry for the first few days. Depending on the type of sutures used, they may be dissolvable or require removal in about 7 to 10 days for areas on the body. It is crucial to minimise tension on the healing wound during the early weeks. This may involve limiting certain physical activities or exercises, especially if the scar is located over a joint or an area with a lot of movement.

The journey of scar maturation takes time. The new scar will initially appear red or pink, which is a sign of healthy blood flow to the healing tissues. Over the following months, this colour will gradually fade. To support this process and prevent a recurrence of raised scarring, your aftercare plan will likely include adjunctive therapies. This often involves starting treatment with silicone gel or sheets once the wound has fully closed, and in some cases, a course of steroid injections may be recommended. Protecting the new scar from sun exposure for at least a year is also essential to prevent it from becoming permanently darkened. Following this structured recovery plan is key to achieving the desired outcome of a flatter, paler, and less conspicuous scar.

Can Hypertrophic Scars Be Fully Removed?

This is one of the most common and important questions patients ask during a consultation for raised scar treatment. It is essential to approach scar revision with realistic expectations, and the honest answer is that a scar cannot be completely removed or erased. Any process that injures the full thickness of the skin, including a surgical incision, will result in the formation of some scar tissue as a natural part of the body's healing mechanism. Therefore, the goal of hypertrophic scar revision is not scar removal, but scar improvement.

The aim of a surgical scar excision is to replace a wide, raised, and highly visible hypertrophic scar with a much finer, flatter, and less noticeable linear scar. By using specialised plastic surgical techniques to remove the abnormal scar tissue and carefully realign the skin edges under minimal tension, we create the best possible conditions for a more favourable healing process. The new scar will be strategically placed, where possible, to follow natural skin lines and creases, further helping to camouflage its appearance over time.

While surgery sets the foundation, the final outcome also depends heavily on post-operative care and your body's individual healing response. Therapies such as silicone sheets, pressure garments, and sometimes steroid injections are vital components of the treatment plan, used to guide the healing process and minimise the risk of the new scar becoming raised. With a comprehensive approach that combines expert surgical technique with diligent aftercare, it is possible to achieve a significant cosmetic improvement, making the scar much less prominent. You can find more information about the general principles of this procedure under scar revision and correction. Ultimately, while the scar will not vanish, its appearance can be dramatically improved to the point where it no longer causes physical discomfort or self-consciousness.

Frequently Asked Questions

What causes hypertrophic scars?

Hypertrophic scars form due to an excessive production of collagen during the body's natural wound healing process, particularly when the injury involves the deeper layers of the skin, known as the dermis. Factors like mechanical tension on the wound, burns, surgical incisions, and infections can all increase the risk of these raised scars developing.

Can hypertrophic scars be flattened?

Yes, hypertrophic scars can often be significantly flattened and improved with the right care and treatment, although they may not fully disappear. Treatments like silicone gel sheets, corticosteroid injections, laser therapy, and pressure garments can all help to reduce their height and soften their texture.

Is hypertrophic scar surgery right for me, and how does it compare to steroid injections?

Whether surgery is right for you depends on several factors, including the scar's size, location, and how it has responded to other treatments. While surgical excision offers rapid removal of scar tissue, recurrence rates can be high if not combined with additional therapies. Steroid injections, particularly with triamcinolone acetonide, are a common and effective first-line treatment, working by inhibiting collagen production and inflammation to flatten and soften the scar. Often, a combination approach using both surgery and steroid injections, or other non-surgical methods, yields the best and most lasting results.

How long does hypertrophic scar revision take, and what is the recovery like?

The duration of a hypertrophic scar revision procedure can vary, typically ranging from a few minutes for injections to one to two hours for surgical revisions, depending on the scar's size, location, and complexity. Recovery also varies; non-surgical treatments usually have minimal to no downtime. Following surgical revision, you may experience some bruising, redness, and swelling for 1-2 weeks, with sutures typically removed in about 7 days. The scar will continue to heal and improve in appearance over several months, with final results often visible after about one year.

Can hypertrophic scars be fully removed or will they completely disappear?

While hypertrophic scars can be significantly improved and made much less noticeable, achieving complete removal or making them fully disappear (meaning the skin returns to its absolutely normal appearance) is rarely possible with current treatments. The goal of hypertrophic scar revision is to optimize the scar's appearance, making it flatter, softer, and more closely matched to the surrounding skin in color. With appropriate treatment, most scars can be improved by 70-90%.
