TREATMENT THEORY
The Er: Bium Glass fractional laser skin reconstruction system adopts fiber laser with 1550nm wavelength and installs a CPG which is arranged in a matrix scanning output, emitting a 50um-80um spot through a high focusing lens, the target tissue is water in the dermis, forming matrix-like holes (0.12mm) around the focal spot penetration directly. The penetration depth of these small spots is about 2mm (the depth is related with solar elastic fibrotic maximum depth). At this point the normal tissue among holes generates a heat bridge which starts the wound rehabilitation reaction and thermal effects between scarfskin and dermal tissue, then experiencing inflammation phase, proliferation phase, remodeling phase. Drugs or cosmetic essence can be applied into the wound for rehabilitation one hour after the irritation. After 3 days proliferation of epidermal cells, inflammatory cell of the dermal layer and the fibroblast cell will be increased. After 7 days,
