Laser resurfacing is one of the most effective tools for acne scars, but not all lasers are equal. The two main players, CO2 and erbium, suit different scars and skin types.
How Resurfacing Works
Ablative lasers remove precise layers of damaged skin and heat the deeper layers, triggering fresh collagen and smoother, more even texture as the skin heals.
CO2 Lasers
CO2 lasers are more powerful and reach deeper, making them well suited to significant, textured acne scarring. The trade-off is more intense treatment and a longer recovery period.
Erbium Lasers
- More precise and gentler on surrounding tissue
- Shorter downtime and less heat
- Ideal for milder scars and more sensitive skin
Choosing the Right One
Deeper, stubborn scars often respond best to CO2, while lighter scarring and those wanting quicker recovery may prefer erbium. Skin tone matters too, so professional assessment is essential.
The Takeaway
Both lasers can dramatically improve acne scars when matched correctly to your skin. A qualified practitioner will weigh scar depth, skin type and downtime to recommend the safest, most effective option.
