The blast effect of laser, laser penetrates the epidermis and reach the endogenous' pigment parts, because of the short time and high energy, pigments absorb the high energy and get a rapid expansion, then break into small particles. These small particles are engulfed by phagocytes and are expelled in body metabolism, finally the pigment gradually fades away, and ultimately achieve the purpose of tattoo removal and pigments removal.
Treatment Area of pico laser machine:
All color tattoo, eyeline and lipline removal
Epidermis and dermis pigment
Nevus of Ota, blue naevus, black nevus, coffee spot
Senile plaques, freckle, sunburn spot and chloasma.
1064nm wavelength: get rid of freckles, eyebrow tattoo, failed eye line tattoo, tattoo, Nevus of Ota, black and blue color and so on pigmentations
532nm wavelength: get rid of freckles, eyebrow tattoo, failed eye line tattoo, tattoo , lips line, shallow red and brown pigment, telangiectasis and so on
755nm wavelength: Remove pigmented such as freckle, age spot, Nevus of Ota, blue naevus, black nevus, coffee, spot, rosacea
Different between Picosecond laser and Q-switch ND YAG laser
At Picosecond laser pulse width, the generated photomechanical stress target pigment particle,making its volume expansion instantaneously and resulting in breakup of target into micro-particles, which is much easier for phagocytes to clear.
Q-switch laser has pulse width of 5ns or more, its photomechanical stress is not efficient compared to picosecond laser, it creates large particles, and with long pulse width, scattering energy goes toward surrounding tissue,resulting in risks of thermal damage.
Therefore, Picosecond laser provide a more effective and more safe treatment than Q-switch laser.
