Hypertrophic scars are thick, raised scars that develop due to excessive collagen production during the healing process. These scars can form on any body part but are commonly found on the chest, back, shoulders, or face. For individuals with hypertrophic acne scars or raised scars on the face, seeking effective hypertrophic scar treatment to reduce discomfort and improve aesthetics. In this guide, we’ll explore the causes, symptoms, & treatment options for hypertrophic scars, with insights into various treatment strategies available for both hypertrophic keloid acne scars and other forms of hypertrophic scarring.
What Are Hypertrophic Scars?
Hypertrophic scars are an exaggerated response to injury or trauma, where the body produces too much collagen. Unlike normal scars, which flatten over time, hypertrophic scars remain raised, often appearing red or purple, and can feel firm or rubbery to the touch. They form due to deep tissue injury, such as surgery, burns, or acne outbreaks. When the skin’s healing process exceeds the necessary limits, it leads to a hypertrophic scar.
What Causes Hypertrophic Scars?
Hypertrophic scars are primarily caused by an overproduction of collagen during healing. This occurs when the body produces more collagen than necessary for the skin to repair itself, resulting in raised scars. Several factors contribute to the formation of hypertrophic scar, including:
- Injury or trauma to the skin: Any damage, including cuts, burns, and deep acne scarring, can lead to a hypertrophic scar.
- Genetics: People with a family history of hypertrophic scar or keloids may be more prone to developing raised scars.
- Infections: If a wound becomes infected, it can lead to abnormal scarring during healing.
- Delayed wound healing: Certain medical conditions, such as diabetes, may delay the healing process, increasing the likelihood of hypertrophic scar formation.
What Are Symptoms of Hypertrophic Scars?
Hypertrophic scarring is typically characterized by:
- Raised appearance: These scars appear elevated above the surrounding skin.
- Red or purple color: Often, hypertrophic scarring starts as dark purple or red scars before eventually fading over time.
- Firm texture: The scar tissue feels firm or rubbery to the touch.
- Itching or discomfort: In some cases, the hypertrophic scar can be itchy or cause mild discomfort.
Hypertrophic Scars vs. Keloid Scars
| Feature | Hypertrophic Scars | Keloid Scars |
| Growth Beyond Wound | Remains within the wound boundary | Extends beyond the wound |
| Appearance | Linear, raised, and confined | Irregular, raised, and spreading |
| Treatment Response | May improve over time with treatment | Requires aggressive treatment |
| Genetic Predisposition | Less genetically influenced | More common in people with a genetic predisposition (African, Asian, Hispanic descent) |
How Are Hypertrophic Scars Treated?
Hypertrophic scar treatment focuses on reducing the appearance of raised scars, alleviating discomfort, and promoting smoother skin texture. Below are some of the most effective treatment options available:
1. Topical Treatments and Creams
Topical treatments are one of the most common methods for treating hypertrophic acne scars. These include silicone gels, corticosteroid creams, or over-the-counter scar treatment ointments. Silicone gel sheets have been shown to help reduce scar formation and flatten raised scars over time. Corticosteroid injections may also reduce inflammation and flatten the hypertrophic scar.
2. Cryotherapy (Freezing)
Cryotherapy involves freezing the hypertrophic scar with liquid nitrogen to destroy the excess collagen in the scar tissue. This technique helps flatten raised scars and is often used for more minor hypertrophic scarring that has not responded to other treatments. It may cause temporary discoloration, but it can significantly reduce the size of the scar over time.
3. Scar Massage and Compression Therapy
Massage therapy and compression garments effectively soften hypertrophic scar and reduce their prominence. Gentle massage techniques applied to the scar tissue can break down excess collagen, while compression garments can help prevent further scarring. These treatments are particularly beneficial for hypertrophic scars on larger body areas such as the chest or back.
4. Steroid Injections
Steroid injections like corticosteroids are frequently used to treat hypertrophic keloid acne scars. These injections help reduce inflammation & flatten the scar tissue. They are typically injected directly into the hypertrophic scar and can be repeated over several sessions to improve the appearance of the scar.
6. Surgical Hypertrophic Scar Removal
In more severe cases where other treatment options have not been successful, surgical hypertrophic scar removal may be considered. This involves excision of the scar tissue, followed by suturing the wound carefully to minimize the formation of new scars. While surgery can be effective for large scars, it is essential to note that new scars can still form after the procedure. It is often combined with other treatments, such as laser therapy, for optimal results.
7. Pressure Therapy
Pressure therapy is another option for individuals with hypertrophic scars. This involves applying controlled pressure to the scar using specialized garments or dressings. This constant pressure helps flatten raised scars and reduce their size over time. It is often used in combination with other treatments to enhance results.
Hypertrophic Scar Healing Stages
Hypertrophic scars go through various healing stages, including:
- Inflammatory Stage: The scar begins to form immediately after the injury, and the body works to heal the wound by forming a clot and sending inflammatory cells to the site.
- Proliferation Stage: New collagen is produced to form the scar tissue. During this stage, the hypertrophic scar may appear red and raised.
- Maturation Stage: Over time, the scar begins to flatten and lighten in color. This stage can last several months to years, during which the hypertrophic scar gradually fades.
It is important to note that hypertrophic scars do not always go through the same stages in the same way for everyone. Depending on their skin type and treatment methods, some people may experience slower or faster healing.

Frequently Asked Questions
How do hypertrophic scars differ from normal scars?
Unlike normal scars, hypertrophic scars are raised and may not flatten over time. They also appear red or purple and can cause itching or discomfort.
Can hypertrophic scars become keloids?
No, hypertrophic scars do not transform into keloid scars but result from excess collagen production.
What is a dark purple scar?
A dark purple scar is hypertrophic in its early stages when excess blood vessels make it appear darker.
Can hypertrophic scars be treated at home?
Silicone sheets, scar creams, and massage therapy can help, but professional treatment is often needed for significant improvement.
Can hypertrophic scars come back after treatment?
Yes, scars may return, especially if treatments are stopped prematurely.
Can hypertrophic scars form after a minor injury?
They can develop even after minor cuts or acne breakouts if collagen production is excessive.
