Fractional resurfacing lasers: Erbium laser
There are two types of fractional lasers: The more gentle and more superficial erbium laser resurfacing. The more aggressive fractional CO2 lasers. In general, the erbium glass fractional fiber laser 1550nm machine treat more superficial changes and are better for younger patients (under 50), mild to moderate acne scarring, and fine wrinkles. The CO2 systems are better for older patients, deeper wrinkles, some skin tightening, deeper acne scarring, and other scars. The fractional CO2 lasers can treat more deeply, but they also can require more downtime than the erbium lasers.
