There are different types of Fraxel, the most popular are either erbium-based (as in Fraxel Restore) or CO2-based treatments (as in Fraxel Repair and DeepFX), the former requiring more treatment sessions for full results. There are other deep fractional lasers on the market. We have extensive experience with several types of these lasers. I suggest DeepFX (without ActiveFX) as an alternative to Fraxel Repair. The results appear to be equivalent when performed with comparable settings.
Given the relatively shallower skin penetration of Fraxel Restore compared to Fractional CO2 Laser, you may need multiple Fraxel treatments before approaching the clinical outcomes of ONE Fractional CO2 Laser resurfacing. Even though Fractional CO2 Laser is superior for rejuvenation, reversal of sun damage and acne scar revision, it also has greater risk of post treatment redness or pigmentation in the hands of less experienced laser surgeons who may not have performed adequate number of laser resurfacing of your skin type.
