CO2 Laser
The most widely used ablative laser in dermatology. At 10,600nm (far-infrared), the beam is invisible to the naked eye and is guided by a visible helium-neon aiming beam. CO2 energy is absorbed by water in tissue regardless of skin colour β vaporising, incising, and coagulating the target zone with minimal scatter, so nearly all energy is concentrated precisely on the treatment area. Used in two modes: controlled ablation (vaporises tissue layer by layer) and incision (cuts cleanly with simultaneous haemostasis). Common indications include mole and pigmented nevus removal, warts, syringoma, neurofibroma, xanthelasma, corns, and condyloma acuminata, as well as fractional resurfacing for acne scars, enlarged pores, and photoaging. Density and depth are adjustable β a light fractional pass gives 3β5 days downtime; a high-density full-resurfacing pass requires 7β10 days.
