TL;DR
17 min read
Fractional laser treatments use a pattern of microscopic treatment zones that leave surrounding tissue intact, enabling faster healing and reduced side effects compared to traditional full-surface laser resurfacing. Available in ablative (CO2, Erbium) and non-ablative modes, fractional lasers treat only a fraction of the skin surface while stimulating collagen production throughout. This technology effectively treats wrinkles, scars, sun damage, and skin texture irregularities with less downtime than traditional resurfacing.
Key Takeaways:
- 1
Fractional lasers treat only a fraction of skin surface, leaving surrounding tissue intact
- 2
Available in ablative (removes skin) and non-ablative (heats without removal) modes
- 3
Ablative fractional lasers (CO2, Erbium) provide more dramatic results with 7-14 days downtime
- 4
Non-ablative fractional lasers offer minimal downtime (1-2 days) with more gradual results
- 5
Effectively treats wrinkles, scars, sun damage, and skin texture irregularities
- 6
Stimulates collagen production throughout treated and surrounding areas for comprehensive improvement
What is Fractional Laser Technology?
Fractional laser technology treats only a fraction of the skin surface at a time, creating microscopic treatment zones surrounded by healthy, untreated skin. This approach allows for faster healing and reduced downtime compared to traditional full-surface treatments.
The technology works by delivering laser energy in a grid pattern, creating controlled micro-injuries that stimulate the body's natural healing process and collagen production.

Frequently Asked Questions
What are fractional laser treatments?
Fractional laser treatments use laser technology to create microscopic treatment zones in the skin, leaving surrounding tissue intact for faster healing. This approach allows for deep skin resurfacing with reduced downtime compared to traditional ablative lasers. Fractional lasers can be ablative (CO2, Erbium) or non-ablative, each offering different benefits for skin rejuvenation.
What is the difference between CO2 and Erbium fractional lasers?
CO2 fractional lasers (10600nm) provide the most dramatic results with deep penetration and significant collagen remodeling, but require 7-14 days of downtime. Erbium fractional lasers (2940nm) are gentler with less downtime (3-7 days) and are ideal for moderate skin concerns. Both are ablative, meaning they remove skin layers, but CO2 is more aggressive.
What is non-ablative fractional laser?
Non-ablative fractional lasers stimulate collagen production without removing skin layers, resulting in no downtime (1-2 days) but requiring more sessions (3-6 treatments) for optimal results. These lasers are ideal for mild wrinkles, skin texture improvement, and overall skin quality enhancement with minimal recovery time.
How many fractional laser sessions are needed?
The number of sessions depends on the laser type: CO2 fractional typically requires 1-3 sessions, Erbium fractional requires 2-4 sessions, and non-ablative fractional requires 3-6 sessions. The number also depends on the severity of skin concerns, treatment area, and individual response to treatment.
What is the recovery time for fractional laser treatments?
Recovery time varies by laser type: CO2 fractional requires 7-14 days, Erbium fractional requires 3-7 days, and non-ablative fractional requires only 1-2 days. During recovery, patients may experience redness, swelling, and skin peeling, with full healing and results visible after several weeks to months.
