When you start looking into laser resurfacing, the first thing you’ll notice is that it’s an umbrella term for several distinct technologies. Here’s an overview of the different treatments that fall under the laser resurfacing category:
Ablative lasers
Ablative lasers remove thin layers of your skin. Carbon dioxide (CO2) and erbium lasers are the most common ablative lasers.
Nonablative lasers
Unlike ablative lasers, nonablative lasers don’t burn off skin. Instead, they stimulate collagen growth and tighten the skin underneath. Examples include pulsed dye, ND:Yag, and Alexandrite lasers.
Fractional lasers
Fractional lasers treat only a fraction of your skin’s surface, leaving the surrounding area untouched. This approach, which can be either ablative or nonablative, allows for a faster healing process.
Intense pulsed light (IPL)
While not technically a laser, IPL works similarly by emitting light pulses. Dermatologists often use it for treating sun damage, dark spots, and rosacea.
Erbium lasers
Erbium laser resurfacing removes surface-level and moderately deep lines and wrinkles on your face, hands, neck, and chest.
One of the primary benefits of erbium laser resurfacing is minimal burning of and damage to the surrounding tissue. This laser causes fewer side effects — swelling, bruising, and redness — so your recovery time should be faster than with CO2 laser resurfacing.
