　　Cryogen spray cooling with R134a has been widely used in the laser dermatology such as port wine stain to prevent the unspecific thermal injury, due to the absorption of laser energy by the melanin in the epidermis.However, the R134a cooling has shown poor efficacy especially in protecting darkly pigmented human skins.
