title: In vivo spectroscopy in dermatology: methods and new fields of application.
abstract: BACKGROUND
  The human skin is an easily accessible organ on which non-invasive examination methods can be applied. Remittance spectroscopy uses registration of the proportion of reflected light from the skin surface. Optical characteristics of skin are determined by scattering, reflection and absorption. The remittance is influenced by various test conditions and topography. Spectroscopic methods are applied for determination of microcirculation, measuring of erythema and pigmentation and in pharmacology and toxicology of applied drugs.
  
  
  CONCLUSIONS
  The standardization of spectroscopic measurement of human skin is essential to reduce error sources. In future a better investigation of skin structures and molecules, which are responsible for optical characteristics of skin and a more precise evaluation of spectroscopic signals are necessary to get more information about the state of skin and to develop new fields of applications, such as early diagnosis of skin diseases or monitoring of metabolic processes.
