Vascular Laser (PDL/Nd:YAG)
PDL/Nd:YAG for vascular lesions and rosacea
이 치료에 대해
PDL (585-595nm) and Nd:YAG (1064nm) are selectively absorbed by oxyhemoglobin in blood vessels, highly effective for telangiectasia, facial redness, and rosacea. PDL targets superficial vessels; Nd:YAG reaches deeper vasculature. Selection depends on lesion depth.
작용 기전
PDL yellow light (585-595nm) absorbed by oxyhemoglobin causes localized heating and thrombosis within vessel. Vessel wall thermal coagulation leads to gradual closure and disappearance. Nd:YAG reaches deeper vessels with similar coagulation effect.
적응증
기대 효과
60-85% redness improvement in 3-6 sessions. 70-90% telangiectasia improvement in 3-4 sessions. Rosacea manageable with maintenance.
