Photorejuvenation and laser beauty are not the same thing. They aim at different projects, but they all belong to the category of laser beauty. Laser is mainly used to treat some pigmentary obstructive dermatoses, such as nevus OTA, coffee-like spots, pigmentary impressions after eyebrow tattoo, etc. Photon rejuvenation is mostly used to treat skin defects and aging caused by age and ultraviolet radiation, such as removing or alleviating various spots and senile spots, removing red blood on the face and smoothing fine wrinkles. Shrink coarse pores, improve facial roughness, remove or dilute acne marks. Most skin aging starts from the age of 25-30, so photon rejuvenation is also called skin beauty technology for consumers over 30 years old.
