C02 LASER RESURFACING FOR HYPERTROPHIC SCAR
CO₂ laser resurfacing is a well-established treatment for hypertrophic scars—those raised, thickened scars that stay within the boundary of the original injury. Here's a focused breakdown to help you explain or understand it clearly, whether you're preparing for a video, presentation, or just personal knowledge.
🔬 What Is CO₂ Laser Resurfacing?
CO₂ (carbon dioxide) lasers use focused light energy to remove thin layers of skin with minimal heat damage to surrounding tissue. It's an ablative laser, meaning it actually vaporizes the top layers of scar tissue to promote smoother, healthier skin regeneration.
🎯 How It Helps Hypertrophic Scars
Hypertrophic scars are made of excess collagen. CO₂ laser resurfacing helps by:
🔥 Ablating thickened scar tissue
💡 Stimulating collagen remodeling (to realign and soften collagen fibers)
🧬 Improving skin texture, flexibility, and appearance
⚖️ Reducing redness and thickness over time
🩺 What to Expect During Treatment
Local anesthesia or numbing cream is usually applied.
The laser pulses across the scarred area, removing layers.
The procedure can take 15–60 minutes, depending on scar size.
Most patients feel a warm or stinging sensation.
⏱️ Recovery & Aftercare
Downtime: 5–10 days for initial healing; redness can persist for weeks.
Aftercare includes:
Keeping the area clean and moisturized
Avoiding sun exposure
Using prescribed ointments to aid healing
⚠️ Risks & Considerations
Temporary swelling, redness, peeling
Hyperpigmentation or hypopigmentation
Infection risk if not properly cared for
Multiple sessions may be needed for best results
✅ Who’s a Good Candidate?
People with persistent, raised hypertrophic scars
Not keloid-prone (CO₂ lasers can aggravate keloids)
Patients with realistic expectations
Individuals not actively using isotretinoin (Accutane)
