Understanding Hypertrophic Scars
Hypertrophic scars are characterized by excessive collagen deposition during the wound healing process. This abnormal proliferation of collagen fibers leads to the raised and often bulky appearance of the scar tissue. While these scars share some similarities with keloids, another type of raised scar, hypertrophic scars tend to remain within the boundaries of the original wound site. Factors influencing their development include genetics, wound tension, inflammation, and the location of the wound.
1. Factors to Consider for Best Treatment Approaches of Hypertrophic Scars
Choosing the most suitable treatment for hypertrophic scars necessitates considering several factors:
Scar Characteristics: The size, location, color, and texture of the scar influence treatment choice. For instance, scars on mobile areas might benefit from pressure therapy, while redness could be targeted with laser therapy.
Patient Profile: A patient’s medical history, skin type, and sensitivity play a crucial role in treatment selection. Individuals prone to keloids might require more cautious approaches.
Treatment Tolerance: Some treatments, like corticosteroid injections, might cause discomfort or side effects. Patient comfort and willingness to undergo multiple sessions should be taken into account.
Treatment Availability: The availability of certain technologies or specialists in a given region can impact the treatment options accessible to patients.
2. Traditional Treatment Approaches for Hypertrophic Scars
Silicone-based Treatments: Silicone sheets or gels have been a cornerstone of scar management for decades. They work by hydrating the skin, reducing collagen production, and flattening scars. These non-invasive treatments are widely accepted due to their ease of use and relatively low risk of side effects.
Corticosteroid Injections: Corticosteroids are injected directly into the scar tissue to suppress inflammation and collagen production. While effective, their use may be limited by the risk of skin thinning and potential recurrence of the scar after treatment cessation.
Pressure Therapy: Applying constant pressure to the scar via garments or adhesive tapes can help flatten hypertrophic scars. This method is particularly effective for scars on joints or areas prone to movement-related tension.
3. Topical Cream and Gel for Reducing Hypertrophic Scars
While there isn’t a one-size-fits-all answer to the best topical cream or gel for reducing hypertrophic scars, there are several options that have shown promise in clinical studies and have been widely used by dermatologists. Here are a few topical treatments that are commonly considered for reducing hypertrophic scars:
Silicone-Based Gels and Sheets: Silicone gels and sheets are among the most well-established and widely used treatments for hypertrophic scars. These products create a protective barrier over the scar and help maintain proper moisture balance. They can also help flatten and soften the scar tissue by regulating collagen production. Brands like ScarAway, Kelo-Cote, and Mederma offer silicone-based products that have garnered positive feedback from users.

Onion Extract Creams: Topical creams containing onion extract, such as Mederma Advanced Scar Gel with Onion Extract, have been shown to help reduce the appearance of scars. Onion extract is believed to have anti-inflammatory and collagen-regulating properties that can contribute to scar improvement.
Topical Vitamin C: Vitamin C is known for its role in collagen synthesis and antioxidant properties. Some topical creams and serums containing vitamin C can help improve the texture and color of scars by promoting collagen remodeling. Products like Vitamin C serums from reputable skincare brands might offer benefits for scar management.
Hyaluronic Acid Creams: Hyaluronic acid is a natural component of the skin that helps maintain hydration and support tissue repair. Some topical creams containing hyaluronic acid can improve the appearance of scars by providing moisture and promoting smoother skin texture.
Topical Retinoids: Retinoids, derived from Vitamin A, are known to promote skin cell turnover and collagen production. Prescription-strength topical retinoids like tretinoin can be used under the guidance of a dermatologist to help with scar remodeling.
Allium cepa Extract (ACE) Gel: ACE gel is derived from onion extract and is used for scar management. Studies have suggested that ACE gel may help in reducing hypertrophic scars when applied regularly.
Contractubex Gel: Contractubex is a gel that contains a combination of allantoin, heparin, and onion extract. It’s designed to improve scar texture and reduce redness, and it has been used for both hypertrophic scars and keloids.
4. The Contemporary Landscape for Hypertrophic Scars
At present, there have been several available treatments in technique for hypertrophic scars:
Laser Therapy: Laser technologies, such as fractional laser and pulsed-dye laser, have gained traction in scar treatment. These lasers target the blood vessels and collagen, effectively reducing scar redness and promoting a smoother texture. Multiple sessions may be required for optimal results.

Microneedling: Microneedling involves creating controlled micro-injuries in the scar tissue using fine needles. This stimulates collagen remodeling and promotes smoother skin texture. Combining microneedling with topical treatments like vitamin C or hyaluronic acid can enhance its efficacy.
Cryotherapy: Cryotherapy, which involves freezing the scar tissue using liquid nitrogen, has shown promise in reducing scar size and redness. It works by damaging the abnormal collagen fibers and triggering a controlled inflammatory response for remodeling.
5. Natural Remedies and Home Treatments for Hypertrophic Scars
Several natural remedies and home treatments are believed to have potential in treating hypertrophic scars. It’s important to note that scientific evidence supporting their effectiveness is often limited. It’s advisable to consult with a healthcare professional before trying any natural remedies, especially if you have a pre-existing medical condition or are using other treatments. Here are a few natural remedies that are sometimes considered for hypertrophic scar treatment:
Aloe Vera Gel: Aloe vera is known for its soothing and moisturizing properties. Applying pure aloe vera gel to the scarred area may help reduce redness and promote healing. Some commercial scar gels and creams also contain aloe vera as an ingredient.
