Ablative fractional laser treatments: fractional photothermolysis
Laser techniques based on photothermolysis
Depending on the type and technical features of the laser, fractional photothermolysis is capable of exerting a powerful stimulating effect on different layers of the dermis (depth of action – up to 5 mm) with a pronounced effect of rejuvenation, normalization of melanogenesis and neurohumoral regulation of the skin area. Let's talk about the method in more detail.
Fractional beam ablative treatments are used to deliver laser energy deeper than the basement membrane and are typically used for interventions at the dermis level. In some clinical cases, it is possible to work above the basement membrane.
Common to these techniques is the formation of “columns” of damage in the dermis and the inability to create a flat plane on the surface of the skin or scar tissue. Fractional ablation drilling technology using an Er:YAG laser allows the creation of ablation columns up to 5 mm deep.
The undoubted advantage of ablative fractional technologies implemented using the Er:YAG laser is the creation of ideal conditions for reducing the area of skin and scar tissue.
