Lasers for rejuvenation: what does the effectiveness of the effect depend on?
Non-ablative effects of fractionated radiation
A large number of laser systems are used for non-ablative fractional effects. This is the largest and most diverse group of lasers. Er:Glass lasers, fiber lasers, diode lasers are used to implement the technologies. This group of lasers is sometimes called “lasers for rejuvenation”.
Common to the group of waves used to implement non-ablative fractionated beam exposure technologies is low absorption by water, which ensures the absence of ablative properties and, therefore, the presence of high coagulation capacity.
All laser generators of this group have low power, and it is impractical to use them in the full beam generation mode for medical purposes. For medical use, it is necessary to use focusing devices - scanners or manual manipulators with additional fractionating lenses.
The properties of laser beams in the wavelength range from 810 nm to 1550 nm have significant differences in the mechanisms of interaction with biological tissues. Common to all these wavelengths is low absorption by melanin and relatively low absorption by water. The main target tissues are various proteins (hemoglobin forms, collagen, elastin) and water.
