KuAn Technology's Picosecond Laser delivers light directly into the skin, with a residence time in the picosecond range. It instantly transmits ultra-short pulses to the skin tissue, shattering pigment clusters into tiny particles that are safely and effectively metabolized and eliminated from the body. Picosecond lasers have selective photothermal effects, meaning they target the specific areas to be removed without damaging normal tissue, such as melanin and hair follicles, achieving effects such as pigment elimination and skin brightening. Secondly, it has a biostimulatory effect, stimulating the proliferation of subcutaneous collagen, making the skin lighter, smoother, healthier, and more radiant. It boasts four unparalleled modes, effectively brightening and promoting collagen regeneration. The rapid energy delivery easily breaks down pigments of various sizes, resulting in more thorough removal of small pigment particles. The low probability of thermal damage avoids side effects. It evenly targets every area of melanin, penetrating deep into the tissue to stimulate collagen regeneration and accelerate skin reconstruction, achieving both pigment removal and a silky smooth skin texture. Comprehensively covers both superficial and deep pigmentation issues, targeting different depths of the skin to easily remove various colored tattoos, purifying the skin tone down to the basal layer, resulting in rejuvenated skin after treatment. Larger light spots and stable energy ensure the melanin is targeted even before the skin feels pain. No anesthesia is required beforehand, making the treatment comfortable and painless. Balanced energy ensures consistent results across the entire skin treatment process.
