Fernanda H. Sakamoto, M.D., Ph.D., from Harvard Medical School in Boston, and colleagues studied absorption spectra of natural and artificially prepared sebum (measured from 200 to 3,000 nm). The Jefferson National Accelerator superconducting free electron laser (FEL) was used to measure photothermal excitation of aqueous gels, artificial sebum, pig skin, human scalp, and forehead skin. In vitro skin samples were exposed to FEL pulses from 1,620 to 1,720 nm, spot diameter 7 to 9.5 mm with exposure through a cold 4 degrees Celsius sapphire window in contact with the skin. Exposed and control tissue samples were stained using hematoxylin and eosin. Nitroblue tetrazolium chloride (NBTC) staining was used to detect thermal denaturation.
