Treatment (Keloid and Hypertrophic Scars)
Both keloid and hypertrophic scars are raised, abnormal scars that form during the healing process after skin injuries. However, they differ in appearance and behavior:
- Keloid Scars:
- Extend beyond the boundaries of the original wound.
- Often have a shiny, smooth appearance and can be larger than the initial injury.
- Tend to persist and may even continue to grow over time.
- Hypertrophic Scars:
- Remain confined to the area of the original injury.
- Are raised and red but usually improve over time, often flattening out with proper treatment.
Common Causes and Contributing Factors
- Genetic Predisposition: A family history of abnormal scarring increases the risk.
- Skin Trauma: Injuries, surgical incisions, burns, acne, or piercings can trigger scar formation.
- Infection or Inflammation: Excessive inflammation during healing may lead to abnormal scar development.
- Location: Areas under high tension (e.g., shoulders, chest, earlobes) are more prone to keloid formation.
Treatment Options for Keloid and Hypertrophic Scars
Non-Surgical Approaches
- Corticosteroid Injections:
- Help reduce inflammation and flatten the scar.
- Often administered in a series of sessions for best results.
- Silicone Gel Sheets or Creams:
- Can help soften and flatten scars over time.
- Often used as part of long-term scar management.
- Cryotherapy:
- Involves freezing the scar tissue, which may reduce its size and discomfort.
- Frequently combined with other treatments.
- Laser Therapy:
- Fractional CO₂ lasers or pulsed dye lasers can improve scar texture, reduce redness, and flatten raised scars.
- Often used in combination with other treatments.
- Pressure Therapy:
- Particularly effective for burn scars, using pressure garments to limit scar growth.
Surgical Options
- Scar Revision Surgery:
- Involves removing the scar tissue and re-closing the wound in a way that minimizes tension.
- Often combined with post-surgical treatments like corticosteroid injections or laser therapy to reduce the risk of recurrence.
- Combination Treatments:
- A multimodal approach combining surgery, steroid injections, and laser therapy often yields the best outcomes for severe keloid scars.
Aftercare & Maintenance
- Sun Protection:
- Use a broad-spectrum sunscreen to protect the scar from UV exposure, which can darken or worsen its appearance.
- Follow-Up Treatments:
- Regular follow-ups with your dermatologist are important to monitor the scar and adjust treatments as needed.
- Gentle Skincare:
- Avoid aggressive scrubbing or harsh products on the scarred area to prevent irritation.
