PICO CARE MAJESTY
World's first 250ps Nd:YAG laser for pigmentation, melasma, tattoo removal & rejuvenation
이 치료에 대해
PICO CARE MAJESTY is the world's first 250 picosecond Nd:YAG laser system developed by Wontech (Korea). Its ultra-short 250ps pulse width generates a powerful photoacoustic effect that shatters melanin pigment into sub-micrometer particles. With 2GW peak power, four wavelengths (1064nm/532nm/595nm/660nm), and seven specialized handpieces, it addresses diverse indications: pigmentation, melasma, freckles, tattoo removal, acne scars, pores, wrinkles, and overall skin rejuvenation. The cavitation effect protects the stratum corneum during treatment, ensuring minimal downtime. FDA and MFDS approved.
작용 기전
The 250ps ultra-short pulse generates a photoacoustic effect against target pigments. Unlike nanosecond lasers that primarily use photothermal effects, the picosecond pulse creates powerful shock waves that fragment melanin and ink particles into fine fragments while minimizing thermal damage to surrounding tissue. Fragmented particles are naturally eliminated by macrophages and immune cells. The MicroLens Array (MLA) handpiece employs LIOB (Laser-Induced Optical Breakdown) and LIC (Laser-Induced Cavitation) effects to promote dermal collagen remodeling, delivering both skin rejuvenation and wrinkle improvement.
적응증
기대 효과
Pigmented lesions show significant improvement after 3-10 sessions. Multi-color tattoos respond well to treatment. 3-8 sessions recommended for overall skin rejuvenation. Results appear 2-4 weeks post-treatment with maximum benefits at 3 months. Minimal downtime of 1-7 days enables rapid return to daily life.
임상 근거
위험 및 부작용
Transient erythema and edema (hours to 1 day), rare PIH (post-inflammatory hyperpigmentation), very rare depigmentation. Preventable with proper settings and post-treatment sun protection. Melasma requires cautious parameter selection (low fluence, multiple sessions recommended). Test patches advised for Fitzpatrick IV-VI skin types.
