　　In laser dermatologic surgery, cryogen spray cooling (CSC) is used to avoid unwanted damage such as scars from skin burning due to the melanin absorption of the laser beam.R134a, R407c and R404a are all considered non-toxic and environmentally compatible candidate cryogens with different boiling point.
