What is a CO2 laser, and what types of lesions can it treat

The CO2 laser emits an infrared beam that is absorbed by water in skin tissue. Because lesion tissue contains water, the beam heats and vaporizes it precisely. Commonly treated lesions include moles, skin tags, viral warts, syringoma, milia, sebaceous hyperplasia, seborrheic keratosis, and senile lentigo. The surgeon removes each lesion layer by layer at the depth planned, with minimal effect on surrounding skin.
