PICO K Picosecond Nd:YAG
Lutronic 450ps Nd:YAG optimized for Asian skin pigmentation
이 치료에 대해
PICO K by Lutronic is a 1064nm Nd:YAG picosecond laser with 450ps pulse width optimized for Asian skin. Selectively destroys melanin for melasma, pigmentation, and spots. Low-fluence multi-session approach minimizes PIH risk while achieving high efficacy. Extensive clinical data for Asian skin types (Fitzpatrick III-V).
작용 기전
1064nm 450ps pulses selectively generate photoacoustic effect on melanin. Reaches deep dermal melanocytes, fragmenting pigment into fine particles. Low-fluence high-repetition delivery enables subcellular pigment destruction with minimal thermal effect on surrounding tissue, reducing PIH risk. Strong evidence base for Asian melasma treatment.
적응증
기대 효과
Significant MASI score reduction in Asian melasma patients. 70-85% improvement in pigmented lesions after 3-8 sessions. Low-fluence approach dramatically reduces PIH incidence vs. conventional lasers.
임상 근거
위험 및 부작용
Transient erythema (hours), mild swelling. Low PIH risk due to low-fluence approach. Post-treatment sun protection essential.
