How CO2 Fractional Laser works
Each microscopic channel vaporizes tissue and heats surrounding collagen; healing skin rebuilds with tighter, smoother texture.
How Potenza works
Needles deliver RF energy at chosen depths, creating controlled heat that stimulates collagen with less surface damage than ablative lasers.
Choose CO2 Fractional Laser if you have
- deeper acne scars
