Background: Multiwavelength lasers are reportedly useful for treating venous lake (VL) in Caucasian patients. However, the same parameters may not be safe for Asian patients with Fitzpatrick skin type (FST) IV.

Purpose: Report experience with using multiwavelength laser for VL treatment in Asian patients with FST IV.

Karst hydrologic system is quite sensitive to the surrounding environment, which leads to changes in the quality of karst water within diel, hours even minutes. Many surface water undergoes changes of pH value, dissolved gas, trace elements, nutrition and other hydrochemical parameters in a daily timescale. The Shuifang spring and its draining pool are located in Jinfo Mountain in Chongqing, the middle karst mountain belonging to temperate climate with an elevation of about 2050 m a.

Background: The Q-switched alexandrite laser used at 752 nm, a wavelength well absorbed by melanin relative to other optically absorbing structures in skin, causes highly selective destruction of pigment-laden cells. In addition, the 75-nanosecond pulse duration produced by this laser approximates the thermal relaxation time for melanosomes, thereby confining the energy to the target. Facial and labial dark brown macules quickly identify patients with Peutz-Jeghers syndrome.
