Understanding Hypertrophic Scars: Causes, Treatment, and Prevention

Understanding TYPES OF SCARING

What is a Hypertrophic Scar?

A hypertrophic scar is a thick, raised scar that develops at the site of a skin injury. Unlike keloids, which can grow beyond the boundaries of the original wound, hypertrophic scars remain within the original wound area but are still elevated and often red or pink in color.

They occur when the body produces too much collagen during the healing process. This overproduction leads to a fibrous, raised tissue that stands out from the surrounding skin

CAUSES AND RISK FACTORS

Several factors can contribute to the formation of hypertrophic scars:

Trauma or surgery: Cuts, burns, or surgical incisions can lead to these scars, especially if the wound is deep or experiences prolonged healing.
Infection or inflammation during wound healing
Tension on the wound edges
Genetic predisposition
Younger age: Young people, especially those between 10–30, tend to heal with more collagen production.

Symptoms and appearance

Raised, thickened scar tissue
Red, pink, or dark in color
May be itchy, tender, or even painful
Limited to the area of the original wound
Often improves slowly over time without treatment

Diagnosis

Diagnosis is typically based on a physical examination by a dermatologist or healthcare provider. In some cases, a biopsy might be performed to distinguish a hypertrophic scar from a keloid or other skin condition.

Treatment Options

Although hypertrophic scars often improve over time, some may require intervention for cosmetic or symptomatic reasons. Treatment options include:

1. Topical Treatments

Silicone sheets or gels: These help flatten and soften scars by hydrating the tissue and regulating collagen production.
Corticosteroid creams: Reduce inflammation and may help soften the scar over time.

2. Injections

Steroid injections Help reduce inflammation and flatten the scar,

3. Laser Therapy

Targets scar tissue to reduce redness, improve texture, and stimulate new skin growth.

4. Microneedling or Dermabrasion

These techniques help remodel the scar by promoting collagen reorganization and skin regeneration.

5. Surgical Revision

In some cases, the scar may be surgically removed and the wound re-closed with special techniques to reduce tension and recurrence

Prevention

While not all scars can be avoided, you can take steps to minimize your risk of developing hypertrophic scars:

Keep wounds clean and moisturized
Avoid sun exposure on healing skin (use SPF or cover the area)
Don’t pick at scabs or wounds
Use silicone sheets or gels early in the healing process
Follow post-operative care instructions if you’ve had surgery

Final Thoughts

Hypertrophic scars can be a frustrating result of the body’s healing process, but they are treatable and often improve over time. If you’re dealing with a scar that is painful, unsightly, or emotionally distressing, consult a dermatologist. With modern dermatological advances, there are effective ways to reduce their appearance and help restore confidence in your skin.
