The Er:bium Glass fractional laser skin reconstruction system adopts fiber laser with 1550nm wavelength and installs a CPG which is arranged in matrix scanning output, emitting 50um-80um spot through a high focusing lens, the target tissue is water in the dermis, forming matrix-like hole (0.12mm) around 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 heat bridge which starts 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 rehabilitation reaction, 1 hour after laser irradiation, the dermal fibrous tissue arranged dense, few inflammatory cells soakage, after 3 days proliferation of epidermal cells, inflammatory cells of dermal layer and fibroblast cells are increased. 7days fibroblasts in dermal layer is increased significantly, 15 days increasing in collagen synthesis, dermal thickening. After laser irradiation there is a certain effect for skin elasticity, skin hemoglobin content, water loss through the skin, sebum content, skin moisture content but no impact on the skin melanin content.
- The target tissue is water, no skin type limit(Fitzpatrick I-VI).
- The output spot diameter is 50-80 um, less thermal ablation and deeper penetration, no scab, no pigmentation, no scar , more safe and effective treatment.
- Random scanning avoids thermal damage caused by heat accumulation, reducing pain of treatment.
- Applied1550nm fiber laser from IPG, the maximum output power is 35W which is 2-3 times of similar equipment, ensuring a deep penetration and long life time.
- Six scan patterns (Circle / Triangle/ Square/ Rectangle / Rhombus /Line) are available via CPG for different parts of skin, satisfying different therapists’ unique request.
- Laser output spot size, energy density, scan pattern, scanning speed, spot density, scanning area are adjustable , which were controlled by the computer operating system for various lesions, the tissue can be gasified at different depths (50-2000um), to ensure a more accurate treatment.
- The YILIYA-1550 can be equipped with different laser power of 15W,25W and 35W.The doctors can choose the most appropriate laser power according to treatment.
