Hypertrophic scars are raised, thickened, and red in color; they form as a result of an overproduction of collagen during the wound-healing process.

When the skin is injured, whether due to surgery, trauma, burns, or other causes, the body initiates a complex process of tissue repair. Collagen, a protein responsible for maintaining the structure and strength of the skin, is produced to fill the wound and aid in the healing process.

Hypertrophic scars typically develop within weeks after the initial injury, and they may continue to thicken and become more prominent over several months.

They are commonly found in areas such as the chest, shoulders, earlobes, and joints, where the skin is under tension or subjected to repetitive motion. Individuals with a genetic predisposition to excessive scarring are more prone to developing hypertrophic scars.

Apart from the aesthetic concerns associated with hypertrophic scars, they can cause symptoms such as itchiness, pain, and tenderness. In some cases, they may restrict movement if they form over joints or contracture-prone areas.

It is important to note that hypertrophic scars can improve and fade over time, but the process can be slow and may take months or even years.

However, various medical treatments and home remedies can help manage hypertrophic scars and promote their gradual reduction in size and appearance.

While hypertrophic scars and keloid scars may share some visual similarities, their behavior, growth patterns, and treatment approaches can differ significantly.

Hypertrophic scars stay within the boundaries of the original wound, appearing raised, thickened, and red; they can improve over time.

On the other hand, keloid scars extend beyond the original wound, are elevated and darker in color, and have a tendency to grow progressively larger. Keloid scars may require more aggressive treatments.

There are several medical treatments available for hypertrophic scars which are performed or prescribed by healthcare professionals. These treatments aim to reduce the thickness, redness, and symptoms associated with hypertrophic scars.

Here are some commonly used medical treatments:

• Corticosteroid Injections: Intralesional corticosteroid injections are a primary treatment option for hypertrophic scars. These injections involve injecting corticosteroid medications, such as triamcinolone, directly into the scar tissue. Corticosteroids help reduce inflammation, suppress collagen production, and soften the scar, resulting in flattening and improved appearance. Multiple injections may be required over a period of time.
• Bleomycin and 5-FU (fluorouracil) injections: Both bleomycin and 5-FU (fluorouracil) injections are administered directly into the hypertrophic scar tissue. These medications work by targeting and damaging the overgrown cells, leading to scar flattening and a reduction in itchiness and pain. To enhance treatment efficacy and minimize potential side effects, these injections are often combined with other therapies such as laser therapy or corticosteroid injections. This combination approach ensures comprehensive scar management and maximizes the benefits of the medication while mitigating any adverse effects.
• Cryotherapy: Cryotherapy involves freezing the hypertrophic scar tissue using liquid nitrogen or other cooling agents. This freezing technique helps destroy excess scar tissue, reduce scar thickness, and improve its appearance. Cryotherapy is typically performed in multiple sessions spaced over several weeks.
• Silicone-based products: Silicone gel or silicone sheets are frequently used in the treatment of hypertrophic scars. These products create a protective barrier over the scar, trapping moisture and improving hydration. They can help flatten and soften scar tissue, reduce redness, and improve elasticity. Silicone products are typically applied daily for several months to achieve optimal results.
• Pressure therapy: Pressure garments or dressings are often used as part of scar management for hypertrophic scars. These pressure-based treatments apply constant pressure to the scar, helping to flatten and soften the scar tissue over time. Pressure therapy is typically used in conjunction with other treatment modalities for maximum effectiveness.
• Microneedling: Microneedling, also known as collagen induction therapy, is a minimally invasive procedure that involves using a device with fine needles to create controlled micro-injuries on the skin’s surface. These tiny punctures stimulate the body’s natural wound-healing process, leading to increased collagen production and remodeling of the scar tissue. It stimulates collagen production, which can help soften and flatten the scar. It can be used on various skin types and scar locations.
• RF Microneedling (radiofrequency microneedling): RF microneedling combines traditional microneedling with the use of radiofrequency energy. This technique involves the insertion of microneedles into the skin, delivering radiofrequency energy into the deeper layers. The combination of microneedling and RF energy enhances collagen stimulation and tightening effects, leading to more significant scar improvement. It causes skin tightening, which can be beneficial for scars with a significant surface area. It also reduces the risk of post-inflammatory hyperpigmentation in darker skin types.

If the aforementioned treatments do not yield the desired results, the following treatments may be considered:

• Laser therapy: Various types of laser treatments can be used to address hypertrophic scars. Pulse dye lasers (PDL) and fractional lasers are commonly employed. PDL targets the blood vessels within the scar tissue, reducing redness and promoting scar remodeling. Fractional lasers deliver controlled heat to the scar, stimulating collagen remodeling and resulting in scar flattening and aesthetic improvement.
• Surgical excision: Surgical excision may be considered for hypertrophic scars that are resistant to other treatments or when there is excessive scar tissue. During the procedure, the scar is surgically removed, and the wound is closed using meticulous techniques to minimize tension and optimize healing. Adjuvant therapies like corticosteroid injections or radiation therapy may be used in combination with surgical excision.

It is important to note that the choice of treatment depends on various factors, such as scar size, location, severity, and individual patient considerations.

Consulting with a healthcare professional or dermatologist is crucial to determine the most suitable treatment approach for hypertrophic scars.

• Massage therapy: Regularly massaging the hypertrophic scar with gentle pressure using your fingertips can help improve blood circulation, break down scar tissue, and promote collagen remodeling. Use a moisturizer, silicone gel, onion extract cream, bio-oil, or vitamin E oil to lubricate the skin during the massage.
• Topical treatments: Over-the-counter creams, gels, and ointments containing ingredients like onion extract or bio-oil can be applied to the scar. These products have been reported to have mild benefits in reducing inflammation and improving scar appearance. Follow the instructions provided and apply them as directed to the scar area.
• Silicone gel sheets: Similar to medical treatment, silicone gel sheets can be used at home. Apply the sheets directly onto the scar, following the instructions provided. These sheets create a protective barrier, maintain moisture, and help flatten the scar tissue over time.
• Natural remedies: Some natural remedies may offer potential benefits for hypertrophic scars. Applying honey, lemon juice, cucumber slices, or bio-oil to the scar area may help moisturize the skin, reduce inflammation, and promote healing.

Remember, home treatments and remedies should be used as adjuncts to medical treatments and under the guidance of a healthcare professional. Consistency and patience are key when using home treatments, as scar improvement may take time.

If the scar shows no signs of improvement or worsens, it is advisable to seek professional advice.

Preventing hypertrophic scar formation can be challenging, especially if you have a genetic predisposition to excessive scarring. However, there are several measures you can take to minimize the risk of developing hypertrophic scars.

Here are some tips for prevention:

• Proper wound care: Taking care of wounds properly can help reduce the likelihood of developing hypertrophic scars. Cleanse the wound gently with mild soap and water, and keep it covered with a sterile bandage until it heals. Avoid picking at scabs or scratching the healing area.
• Early treatment: Seek prompt medical attention for significant wounds or injuries, as early intervention can help minimize scar formation. Discuss treatment options to prevent excessive scarring with your healthcare professional.
• Minimize tension and pressure: Avoid subjecting wounds to excessive tension or pressure during the healing process. Protect healing wounds from stretching or movement that could contribute to increased scar formation. For example, use appropriate supports or bandages for joint injuries.
• Sun protection: Protect healing wounds and scars from sun exposure. UV rays can cause pigmentation changes and make scars more visible. Apply sunscreen with a high SPF to the healing area or cover it with clothing or a bandage when going outdoors.
• Healthy lifestyle: Maintaining overall skin health can contribute to better wound healing and reduce the risk of excessive scarring. Eat a balanced diet rich in vitamins and minerals, stay hydrated, and avoid smoking, as smoking can impair wound healing.
• Avoid irritants: Minimize exposure to irritants or allergens that could potentially delay wound healing or contribute to scar formation. Be cautious with new skincare products and avoid using harsh chemicals on healing wounds.
• Considerations for elective surgeries and vitamin D: If you know that you tend to get hypertrophic scars, it is a good idea to avoid elective surgeries when possible. Talk to your doctor about this before any planned procedure. Also, make sure you have sufficient vitamin D levels before surgery, as this might help prevent hypertrophic scars from forming.
• Follow medical advice: If you have a history of excessive scarring or are at higher risk for hypertrophic scars, consult with a healthcare professional or dermatologist. They can provide personalized advice and recommend preventive measures or treatments tailored to your specific situation.

Remember, while these tips can help reduce the risk of hypertrophic scars, it is not always possible to completely prevent their formation. If you notice any abnormal scar development or have concerns about your scars, consult with a healthcare professional for proper evaluation and guidance.

Hypertrophic scars can be bothersome both physically and emotionally. Fortunately, there are several treatment options available, both medical and home-based, that can effectively reduce scar thickness, redness, and associated symptoms.

By following proper wound care techniques and taking preventive measures, individuals can minimize the risk of hypertrophic scar formation.

Remember, consulting with a healthcare professional is essential to determine the most suitable treatment approach for your specific situation.
