Inside Hypertrophic Scar
Understanding and Treating Hypertrophic Scars
Hypertrophic scars are thick, raised scars that form in areas of skin injury. They differ from keloids by remaining within the boundaries of the original wound. Initially, these scars may present as red or purple and tend to become paler over time.
When skin heals after being injured, it can produce an excess amount of collagen. This surplus of collagen accumulates in the skin, resulting in a raised, bumpy texture.
The aim of treating hypertrophic scars is to minimize their visibility and alleviate discomfort. Common treatments include:
- Silicone sheets or gels: These are applied directly to the scar to help in flattening and fading its appearance.
- Steroid injections: These are used to reduce inflammation and can help flatten the scar.
- Laser therapy: This treatment option works on reducing redness and improving the scar's texture.
- Surgery: For severe cases, surgical removal of large scars might be considered.
Early intervention in the treatment process is linked to improved outcomes in the appearance and texture of hypertrophic scars.
Corticosteroid and Laser Therapy for Scar Reduction
Corticosteroid injections and laser therapy are two methods used for scar reduction.
Corticosteroid injections aim at raised, thickened scar tissue. A fine needle is used to inject corticosteroid directly into the scar, reducing inflammation and flattening and softening thick scars over time. This treatment is particularly useful for keloids or hypertrophic scars, which are red, raised, and sometimes painful or itchy.
Laser therapy utilizes focused light to treat scar tissue, with different types of lasers being employed based on the scar's characteristics - color, size, thickness. Pulsed-dye lasers target blood vessels in the scar to reduce redness, while fractional lasers create micro-columns in the skin that stimulate new collagen production without damaging surrounding tissues.
- Corticosteroid injections can significantly flatten thick scars but might require multiple sessions.
- Laser therapy offers precision with minimal injury to surrounding skin areas and improves both texture and appearance, though it could involve several treatments based on the initial response.
The choice between these treatments depends on various factors, including the age of the person and the type and severity of the scarring.

Bleomycin Injections and Cryotherapy for Hypertrophic Scars
Hypertrophic scars are thick, raised scars that can occur after surgery or injury, potentially causing itchiness or pain and affecting the skin's appearance. Bleomycin injections and cryotherapy are two treatments available for these types of scars.
Bleomycin, a medication commonly used in cancer treatment, can also be applied in the treatment of hypertrophic scars by injecting it directly into the affected area. This method aims to block the production of collagen, which is responsible for the thick and raised nature of these scars. The treatment involves a series of injections administered over several months. While quick, the procedure may lead to some level of discomfort, akin to that experienced with other injection types.
- Benefits:
- Effectiveness: A significant improvement is observed in many cases.
- Minimal Side Effects: There is a lower risk of additional scarring compared to surgical options.
Cryotherapy treats hypertrophic scars by freezing the scar tissue using liquid nitrogen. This action leads to the death of the scarred cells, resulting in the scar becoming flatter and softer over time. The treatment is brief and requires multiple sessions, which are spaced a few weeks apart.
- Benefits:
- Non-invasive: The process does not involve incisions or needles.
- Quick Recovery: There is minimal downtime after each session.
Both bleomycin injections and cryotherapy have been found to be effective for hypertrophic scars in various cases. The effectiveness of these treatments can vary depending on the individual's specific condition.
Surgical and Home Remedies for Scar Care
Scars are a natural part of the healing process, and there are methods to minimize their appearance for cosmetic or comfort reasons. Both surgical and home remedies can be effective in managing scar care.
Surgical Options
-
Laser Therapy
- Laser therapy utilizes focused light to reduce scar tissue, making scars less noticeable without harming surrounding skin. Different types of lasers are available, depending on the scar's nature.
-
Scar Revision Surgery
- This procedure involves removing the old scar and closing it with fine stitches to achieve a less conspicuous mark. It is often considered for large or very noticeable scars.
-
Skin Grafts
- For severe cases, especially where mobility is affected, skin grafts may be recommended. The procedure involves taking healthy skin from another body part to cover the damaged area.
Home Remedies
-
Silicone Sheets or Gels
- Silicone sheets or gels can be applied over scars to help flatten them over time. These are easily accessible without a prescription.
-
Onion Extract Gel
- Onion extract gel, an over-the-counter product, has shown improvements in scar texture and appearance with regular application.
-
Massage and Moisturization
- Massaging scars with lotion or oil can keep the tissue soft and may reduce visibility. Applying sunblock on exposed scars is crucial as UV rays can darken them.
Both surgical options and home remedies provide paths towards improved scar care. Results vary based on individual factors such as age, genetics, type of injury, etc.
Distinguishing Keloid from Hypertrophic Scars and Preventing Future Scarring
Keloids and hypertrophic scars, while similar in nature, exhibit distinct characteristics. Keloids extend beyond the boundary of the original wound, often appearing shiny and possibly feeling rubbery, with the potential to grow significantly over time. In contrast, hypertrophic scars are raised, red areas that form along the site of an injury but do not extend beyond its initial boundaries.
To minimize future scarring, it is important for new wounds to be kept clean to reduce the risk of infection, which can exacerbate scarring.
- Silicone sheets or gel have been shown to help in reducing scar formation by hydrating the tissue.
- Furthermore, protection against UV rays is crucial as they can intensify the visibility of scars by darkening them.
Early intervention can influence the eventual appearance of scars, with prevention strategies being more effective when implemented soon after the onset of wound healing.
