이 치료에 대해
Spot removal laser targets solar lentigines and shallow pigmented lesions using Q-switched or picosecond lasers. Efficiently shatters UV-accumulated melanin in epidermal basal layer for complete removal in 1-2 sessions.
작용 기전
532nm (green) or 1064nm wavelength selectively absorbed by epidermal melanin; short pulse creates pressure wave. Pigment shatters to micro-particles, cleared by macrophages over weeks. Shallow lesions usually completely removed in 1-2 sessions.
적응증
색소·칙칙함일반 적응증(상세 설명 참고)
기대 효과
90-100% spot removal in 1-2 sessions. Complete resolution in 2-4 weeks post-treatment. Low recurrence rate.
