The CO2 laser is a fractional therapeutic laser indicated to treat scars and make the less visible.
This laser treats a fraction of the skin through a scanner of laser light points with selected parameters that vary depending on the type of skin, the degree of severity of the scar and the desired treatment results.
The laser light acts on the epidermis and the dermis by heating the epidermic cells and collagen in the dermis at high temperatures. This heat eventually results in a replacement of the epidermis and a denaturation of the old collagen and fibrosis of the scar of the dermis, stimulating the formation of new, higher quality collagen to repair the scar.
Technologically, this laser to treat scars acts in a fractional way. That means that the laser produces microscopic light acting columns in the skin (epidermis and dermis) leaving intact tissue between these columns. Thus, the tissue of the columns will be renewed producing a new collagen and a more trophic epidermis aided by healthy surrounding tissue that promotes this repair. It is a natural process of the body itself replacing the damaged collagen by a new, healthy and shiny skin with less visible scars.
CO2 laser treatment to erase scars is personalized since it works with a computer that allows the doctor choose the right parameters for each patient. The professional chooses the power, the time, the spot size, the spot shape…to act in superficial, intermediate and deep layers according to the need.
