Applications: 532nm wavelength: get rid of freckles, eyebrow tattoo, failed eye line tattoo, tattoo , lips line, pigment, telangiectasia in shallow red, brown and pink and etc. light color 1064nm wavelength: get rid of freckles and yellow brown spot, eyebrow tattoo, failed eye line tattoo, tattoo, Birthmark and Nevus of Ota, pigmentation and age spot, nevus in black and blue, scarlet red, deep coffee and etc. deep color. 1320nm wavelength: shrink pores removal, poblackhead removal, skin tightening and whitening, skin rejuvenation, wrinkle removal . Working Principle: The special wavelength of YAG laser can penetrate skin of human body according to the theory and practice of "selective laser decomposing", the instrument uses the laser-wave to break Chromatophore into pieces which can be naturally absorbed by the body. So that it achieves the purpose of de-freckling. The Q-switched Nd:YAG laser radiates the light with a specific wavelength in high peak energy pulse; hence the light penetrates the tissue only for an ultra-short nanosecond. The light is absorbed by the pigment tissue and results in an instantaneous blast, that is Light blasting principle. The pigment particles are shattered into fragments, parts of them will be bounced out of the skin and other parts will be split into tiny particles that can be engulfed by phagocytes and then metabolized by the lymphatic system. The 1064nm wavelength will shatters and removes the black and blue pigments while the 532nm wavelength will shatters and removes red, pink, purple and brown pigments of the tattoo or other pigmentations without damaging the normal tissue Specialty of QM-Q1 New Medical and Elegant design Ergonomic design handle, super long lifespan which can reach 2 millions shots ! 2. 3 Laser tips: 532nm, 1064nm, 1320nm can meet different pigments and black doll treatments Non-pain tips are for option Technical Specifications: Peak Power 500W Wavelength (Spectrum) 1064nm & 532nm (1320nm optional) Energy Density (Fluence) 1-2000mJ Spot Size 2-7mm Pulse Repetition Rate 1-10Hz Pulse Duration
