Lasers may sound futuristic, but CO2 laser resurfacing has been around for a long time. A treatment from the CO2RE fractional laser is fast with minimal downtime. The latest innovation in lasers is a big leap forward because it simultaneously works on the surface and beneath your skin. It treats a fraction of the skin at a time, making precise, microscopic wounds. As they heal, your body naturally produces collagen and healthy new skin cells.
