The Q-switched Nd:YAG laser radiates the light with a specific wavelength in high peak energy pulses, hence the light penetrates into the tissue only for a nanosecond. The light is absorbed by the pigmentation and results in an instantaneous blast, that is Light blasting principle. The pigmentation particles are shattered into fragments, some can be bounced out of the skin and others can be split into tiny particles that can be engulfed by phagocytes and then eliminated by the lymphatic system.
Selective Photothermolysis: Laser tattoo removal is take advantage of selective photothermolysis, Photothermolysis targets melanoma with effectiveness depending on the absorption spectrum of each pigment. 4 The epidermis, dermis, and skin appendages are only minimally damaged in the process. The pigments absorb short laser pulses, which produce a high-intensity light in the pigments that is converted into heat. Shortly Shock waves shatter the pigment particles, achieving the selective death of the pigment-containing cells. Lastly, the cell debris is phagocytized and transported to regional lymph nodes. Although they are hardly visible, some residual, scattered particles remain in the dermis. Only superficial pigment fragments are entirely eliminated during epidermal desquamation . To produce the most effective treatment results, the laser wavelength must be absorbed by the ink, the heat should be confined to the target, and adequate energy must be delivered.
1, Top-homogeneous beam (different from Gauss and Flat-Top mode) to avoid excessive epidermis damage. 2, 8ns single pulse width and 800mj single pulse energy ensures an effective removal of all pigmented lesions. 3, Two kinds of square spot size (2mmx2mm, 3mmx3mm) for precise treatment.
Tattoo ( black, brown, red, blue) Pigmented lesions : Sunspot ,Ota's nevus, Melasma ,Age spots, CALMS Nevus Zygomatices Laser facial : Skin rejuvenation and resurfacing, fine wrinkles and expression lines removal, pigmentations reduction such as sunspots and freckles firms up skin tone.
