Hypertrophic scars—often described as "thick raised scars within a wound"—are a common but often misunderstood result of the body’s healing process. This guide is designed to help patients understand hypertrophic scars and explore treatment options, with a special focus on the advanced medical care available in South Korea.

Hypertrophic scars are a specific type of abnormal wound healing. They form when the body produces too much extracellular matrix and connective tissue at the site of a skin injury. These scars are firm, raised, and result from an overproduction of proteins like fibrinogen and collagen during healing.

They usually appear within a week to a month after an injury that goes deep into the skin’s dermal layer. Common causes include burns, surgical incisions, insect bites, tattoos, acne, chickenpox, or piercings. Visually, hypertrophic scars are thick, elevated, and often pink or red, sometimes accompanied by itching or tenderness. They tend to develop on joints or areas under tension, such as the chest, upper back, or shoulders.

The biological process behind hypertrophic scars involves an imbalance in Transforming Growth Factor-beta (TGF-beta). Overexpression of TGF-beta 1 and 2, and reduced TGF-beta 3, leads to increased collagen production—up to three times more than normal healing. This means hypertrophic scars are not just a surface issue but a sign of deeper biological imbalance. Effective treatments must target these cellular and molecular pathways, which is why therapies like corticosteroid injections or certain lasers work—they influence cellular activity and collagen metabolism. For patients, this highlights the importance of consulting medical professionals who understand the complex biology of scar formation.

Common Terms and Pseudonyms

While "hypertrophic scar" is the medical term, people often use phrases like "raised scar," "thickened scar," "red scar," or "abnormal scar." Recognizing these terms helps bridge the gap between everyday language and medical terminology, making information more accessible and empowering patients to connect their experiences with expert advice.

Distinguishing Hypertrophic Scars from Keloids

It’s important to know the difference between hypertrophic scars and keloids, as they require different treatments.

Hypertrophic Scars:

• Stay within the original wound’s boundaries.
• May flatten or regress over time, even without treatment.
• Collagen fibers are arranged in a regular, parallel pattern.
• Occur in people of all skin tones and are not strongly linked to genetics.
• More common than keloids.

Keloids:

• Extend beyond the original wound into healthy skin.
• Rarely regress and often keep growing.
• Collagen appears in a random, whorl-like pattern.
• More common in people with darker skin and often have a genetic link.
• Frequently form on earlobes, shoulders, chest, back, cheeks, and knees.

Both types can cause itching, pain, movement restriction, and cosmetic concerns. However, hypertrophic scars generally have a better prognosis and may need less aggressive treatment. Accurate diagnosis by a medical professional is crucial, as mistaking a keloid for a hypertrophic scar can lead to ineffective treatment and higher recurrence risk.

Why Treatment Matters: Symptoms and Impact

Hypertrophic scars can flatten over months or a year, but they often cause discomfort and limit movement, especially over joints. Beyond physical symptoms like itching and pain, these scars can cause significant cosmetic concerns and emotional distress, affecting quality of life. Studies show that hypertrophic scars can lower a patient’s standard of living and cause emotional harm. Treatment is not just about appearance—it’s about relieving symptoms and restoring function. Success should be measured by improvements in itching, pain, and quality of life, not just visual changes.

Comprehensive Medical Procedures for Hypertrophic Scar Treatment

The main goal of hypertrophic scar treatment is to reduce the scar’s size, hardness, redness, and stiffness, while improving its flexibility and appearance. Complete removal is rare, but significant improvement is possible.

Early intervention is key—treating scars early often leads to better outcomes. Combination therapy is common, as using multiple treatments can address different aspects of scar formation. Patients should seek medical advice as soon as a hypertrophic scar develops and be open to personalized, multi-modal treatment plans.

Non-Invasive and Minimally Invasive Approaches

Silicone Sheets and Gels

Silicone scar sheets and gels are considered the gold standard for non-invasive hypertrophic scar treatment. They work by keeping the scar hydrated, which prevents excessive collagen production. Silicone also provides gentle pressure and a barrier, and slightly increases local temperature to boost collagenase activity.

These sheets or gels are applied directly to the scar, ideally for at least 12 hours a day, and up to 24 hours if tolerated. Treatment usually lasts 2-3 months for new scars and up to 6-12 months for older ones. Silicone therapy is safe for sensitive skin, with mild side effects like irritation or redness. It should not be used on open wounds. Consistent, long-term use is crucial for success, making this an accessible and cost-effective first-line therapy.

Corticosteroid Injections (Intralesional Corticosteroid Injection)

Corticosteroid injections, often using Triamcinolone (Kenalog), are injected directly into the scar. They break down collagen fibers, reduce scar tissue, inhibit cell growth, and have anti-inflammatory effects. Injections are usually given every 4-6 weeks, with a limit of about five sessions to minimize side effects.

About 70-80% of patients respond well, with significant improvements in itching and pain. Side effects can include discomfort, skin thinning, lighter patches, and visible veins. Rarely, systemic effects may occur. Patients should be prepared for a series of injections and discuss potential side effects with their dermatologist.

Cryotherapy

Cryotherapy uses extreme cold, usually liquid nitrogen, to freeze scar tissue. Intralesional cryotherapy involves inserting a needle into the scar to freeze it from the inside out, destroying abnormal collagen and reducing scar volume. It’s especially effective for smaller scars and is safe for darker skin types. Side effects can include lighter skin patches, so careful temperature control is important.

Laser Therapy

Laser therapy uses focused light to remodel scar tissue. Different lasers target redness, discoloration, or texture:

• Pulsed Dye Lasers (PDL): Reduce redness and flatten scars.
• Fractional CO2 Lasers: Resurface the skin and stimulate new collagen.
• Nonablative Fractional Lasers: Improve pigmentation and thickness without removing skin.
• Ablative Lasers: Used for resurfacing traumatic and surgical scars.

Multiple sessions are usually needed, and side effects can include swelling, redness, and mild pain. While laser therapy is promising, evidence for its effectiveness as a standalone treatment is limited, so it’s often used as part of a combination approach.

Surgical Interventions

Surgical Excision

For large or unresponsive scars, surgery may be considered. The scar is cut out and the wound closed, sometimes with skin grafts. Techniques like Z-plasty and W-plasty help blend the scar with surrounding skin. Surgery always leaves a new scar, so it’s usually combined with other treatments to prevent recurrence. Risks include bleeding, infection, and scar recurrence.

Radiation Therapy (as an adjunct to surgery)

Radiation therapy uses low-dose radiation to target scar tissue, usually after surgical excision. It’s safe at these doses and helps prevent scar regrowth. Most patients need only a few short sessions, with minimal side effects like redness or dry skin. Long-term effects can include skin color changes or increased sun sensitivity.

Emerging and Adjunctive Therapies

Other therapies can be used alone or in combination:

• Pressure Therapy: Uses elastic garments to reduce collagen synthesis.
• Bleomycin Injection: Can improve scar appearance and reduce discomfort.
• Microneedle Therapy: Tiny needles trigger healing and improve scar color, often combined with serums or PRP.
• Retinoids: Topical creams help reduce scar size and fade color.
• Platelet-Rich Plasma (PRP) Injections: Use the patient’s own blood to promote healing and reduce pro-fibrotic molecules.
• Topical Creams (Corticosteroid Creams, Polyurethane Dressings): Reduce inflammation and help restore normal color.

These options show that scar management is evolving, with personalized, multi-modal plans offering the best results.
