该 🦉 技 🐘 术包 🐠 括以下步骤:
1. 选择性吸收:激光器产生波长特定(通常为 🐞 532nm、755nm 或 1064nm)的激光束,该波长 🌳 (被)色素如黑色素强烈吸收。
2. 光热转换:被吸收的激光能量被转化 🦉 为热能。
3. 选择性破坏:产生的热量选择 🦉 性地升高色素颗粒温度,导致其破裂和分解。

1. 调 🐘 Q纳 🌷 秒激光 🌷
激光 🐞 脉冲时间短 🐎 (纳秒级),能量高
适用于浅表色 🌸 斑,如雀斑、晒斑 🌴
治疗 🐡 后可能 🦉 出现短暂结痂
2. 皮秒激光 🦅
激光脉冲时间更短(皮秒级),能 🦟 量 🕷 更高
适用于较深层 🐟 色斑,如真皮斑、太田痣
治疗后结 🕸 痂时间更短
3. 超脉冲 🦋 CO2激 🌷 光 🐦
激光波长较 🦋 长,能量高
适用于去除凸起 💐 的 🦈 色斑,如色素痣
