The Science of Hypertrophic Scar Formation: What Happens Under the Skin

Scars are a natural part of the body’s healing process, but not all scars heal the same way. For some patients, the result is a hypertrophic scar, a raised, thickened area of skin that can be uncomfortable, noticeable, and difficult to manage. At International Keloid & Scar Treatment Center in Orlando, FL, we focus on understanding the science behind these scars to provide more effective, targeted treatment options.

What Causes Hypertrophic Scars?

When your skin is injured, whether from surgery, burns, acne, or trauma, your body immediately begins repairing the damage. This process involves producing collagen, a protein that helps rebuild tissue.

In normal healing, collagen production slows once the wound is closed. However, in hypertrophic scars, the body continues to produce excess collagen, resulting in a raised, often firm scar that remains within the boundaries of the original injury.

Studies show that hypertrophic scars develop in up to 40–70% of surgical wounds and as many as 90% of burn injuries, making them a relatively common concern.

What’s Happening Beneath the Surface?

Hypertrophic scars form due to an imbalance in the body’s healing response. Several key factors are involved:

• Excess collagen production: Fibroblast cells become overactive, producing more collagen than needed
• Disorganized tissue structure: Instead of laying down smoothly, collagen fibers form thick, irregular bundles
• Prolonged inflammation: The body remains in “repair mode” longer than necessary
• Increased tension on the skin: Areas like the chest, shoulders, and joints are more prone due to constant movement

This combination results in a scar that appears raised, red or dark, and sometimes itchy or painful.

Who Is More Likely to Develop Them?

While anyone can develop hypertrophic scars, certain factors increase the likelihood:

• Younger individuals (ages 10–30)
• Areas of high skin tension
• Delayed or complicated wound healing
• Certain skin types and genetic predispositions

Understanding these risk factors helps guide both prevention and treatment strategies.

Why These Scars Can Be Difficult to Treat

Because hypertrophic scars are driven by ongoing biological activity beneath the skin, surface-level treatments alone are often not enough. Without proper intervention, these scars can take one to two years or longer to naturally flatten, and in some cases, they may not fully resolve.

That’s why early and targeted treatment is important.

Advanced Treatment Options for Relief

At International Keloid & Scar Treatment Center, we use advanced, science-based treatments designed to address the underlying causes of hypertrophic scars, not just their appearance.

Treatment options may include:

• Corticosteroid injections to reduce inflammation and collagen production
• Laser therapy to improve texture, color, and thickness
• Silicone-based treatments to help regulate moisture and healing
• Combination therapies that target multiple aspects of scar formation

Research shows that combination approaches can significantly improve outcomes, with many patients experiencing a visible reduction in scar height and symptoms within a few treatment sessions.

A Personalized Approach to Healing

Every scar is different, and effective treatment requires a customized plan. Our team evaluates the size, location, and maturity of your scar, along with your skin type and medical history, to determine the most effective approach.
