The principle of cell light fusion carbon dioxide fractional laser makes intense pulsed light act on the target tissue in the form of points. Cellular light is based on the innovative research of selective photothermal effect and focal photothermal effect, which realizes the destruction of the target tissue after absorbing light energy while maximally protecting the surrounding normal skin, that is, reducing thermal damage, and the therapeutic effect is as high as 80%. In order to meet the ultimate pursuit of the majority of consumers for the effect.
