CO2 lasers are high energy fractional lasers that will cause moderate damage to treated skin and the skin will consequently shed. In this way, CO2 laser stimulates the skin to ultimately repair and regenerate itself.
Since CO2 lasers are a kind of exfoliating laser, treatment using them is widely applied to clinical use combined with lattice techniques. In other words, CO2 lasers are split into several tiny laser beams, and when they hit the skin, they form evenly spread light spots, creating a thermo-exfoliating area, thermo-solidifying area and thermo-reacting area, which will subsequently lead to a series of self-reparation processes as a reaction in the body.
The advantage of this technology lies in two points. On the one hand, it maintains both the depth of interaction and power of CO2 laser. On the other hand, because there is normal skin between each spots, damaged skin can repair in a short time, which gives consideration to not only safety but also the curative effect. Therefore, it is broadly used in scar removal, wrinkle reduction, spot removal and other beauty treatments.
