Laser Toning
Low-fluence Q-switched for gradual melasma improvement
이 치료에 대해
Laser toning uses 1064nm Q-switched laser at low fluence (1-3J/cm²) in multiple passes to gradually improve refractory melasma. Shorter pulse width than traditional nanosecond lasers enables fine melanin shattering with minimal collateral tissue damage.
Multi-pass gradual approach reduces irritant dermatitis risk while clearing pigment—preferred for Asian skin types due to lower PIH risk.
작용 기전
1064nm wavelength selectively absorbed by deep melanin; low-fluence multiple pulses gradually shatter pigment. Inter-treatment intervals (2-4 weeks) allow natural wound healing, reducing inflammation while promoting pigment clearance. Efficient macrophage melanin phagocytosis minimizes PIH risk.
적응증
기대 효과
60-80% melasma improvement expected after 8-10 sessions. Gradual improvement visible 2-4 weeks post-treatment. Results are durable; maintenance every 3-6 months.

위험 및 부작용
Transient redness (hours), mild swelling. Rare aesthetic PIH. Proper fluence settings and post-care sun protection essential.
