JEWELRY POWDERS AND FAR-INFRARED RAYS 183 (a) (b) Figure 8. Thermograph of the jade powder-containing cream. Thermographs were taken at a constant room temperature of 25 ø. (a) Thermographed before treatment temperatures of both sides of the subjects' faces were almost the same. (b) Thermographs taken 330 seconds after treatment.
