Hypertrophic scars are raised, thickened scars that develop at the site of skin injury. They result from an abnormal response to wound healing, where the body produces excess collagen during the repair process. Unlike keloid scars, which can grow beyond the original wound boundary, hypertrophic scars remain confined to the area of the injury.
Hypertrophic scarring can occur due to:
Surgical incisions
Trauma or accidents
Burns
Piercings or tattoos
Skin infections
Acne lesions
Prolonged wound healing
The likelihood of developing these scars can increase with:
Delayed wound healing
High tension or movement at the wound site
Infections during healing
Genetic predisposition
Red or pink color initially (may fade over time)
Firm and raised texture
Itching or discomfort
Restricted to the original wound area
May improve naturally over time, especially within 12 to 18 months
| Feature | Hypertrophic Scars | Keloid Scars |
|---|---|---|
| Growth | Stay within the wound boundary | Extend beyond the original injury |
| Texture | Raised, thick, firm | Raised, shiny, rubbery |
| Duration | May flatten over time | Tend to persist or grow |
| Treatment | Often responds well to treatment | More resistant to treatment |
Treatment depends on the severity and location of the scar. Common treatments include:
Helps flatten and soften the scar
Reduces redness and discomfort
Reduces inflammation and scar tissue
Usually given monthly for several sessions
Targets pigmentation and texture
Fractional laser can stimulate collagen remodeling
Used primarily for burn scars
Special garments apply constant pressure to flatten the scar
Removing the scar and re-closing the wound in a cleaner way
Often combined with steroid or silicone therapy post-op
Freezes scar tissue using liquid nitrogen
More common for keloids but sometimes used for hypertrophic scars
Proper wound care: Clean, protect, and moisturize healing wounds
Avoid excessive movement at the healing site
Use silicone products early in healing for high-risk individuals
Avoid sun exposure: Use sunscreen or cover the area to reduce discoloration
Seek early treatment if the scar starts to raise or thicken
Individuals with darker skin tones
Those with a family history of hypertrophic or keloid scarring
People undergoing multiple surgeries or who have had burn injuries
Hypertrophic scars are a common but treatable skin condition that arises from overactive wound healing. While they may resolve on their own in some cases, early intervention can significantly improve the cosmetic outcome and reduce discomfort. If you’re concerned about a developing scar, consult a dermatologist or skin specialist to explore the best treatment options.
