ST-220 Q-Switched Nd:YAG Laser
Tackle All the Pigmentation


How does Nd:YAG Laser work?
LASER stands for the word “Light Amplification by Stimulated Emission of Radiation.” It emits high energy of light at single wavelength to target the chromophore in our skin. The selective photothermolysis process is therefore activated to heat up and destroy the unwanted cells such as pigmentations and melanin.

ST-220 uses the crystal Nd:YAG (neodymium-doped yttrium aluminum garnet) as a medium to radiate laser energy. It has the wavelength of 1064nm which enables the high peak energy the penetrate deeper to the skin. Besides, the chromophore hemoglobin and melanin all has high absorption toward the 1064nm wavelength and that makes Nd:YAG laser ideal for remove dark colored tattoo or red vascular lesions.


Pigments deep in the dermis can be destroyed and degraded by Nd:YAG laser energy.

Demolish the Color
ST-220 Nd:YAG Laser generates photomechanical effect targeted at melanin and pigmentations leaving the surrounding skin intact. After the pigmented cells absorbing the laser energy and therefore being heated up, it would be destructed into small particles and gradually excreted by phagocytosis process.

Double Frequency for More Applications
ST-220 Nd:YAG laser can double the 1064nm frequency into 532nm that the absorption of hemoglobin is even higher; the red colored pigment is therefore destroyed more efficiently and effectively.
