DESCRIPTION:Dermatology\, a subsidiary medical discipline whos
 e attentions had mainly focused on skin rashes\, e
 ruptions\, and syphilis\, transformed its scope an
 d part of its mission in the latter half of the ce
 ntury.  Beginning in the 1960s\, environmental app
 rehensions of the thinning of the ozone layer and 
 associated concerns with rising incidences of skin
  cancer contributed to diverse investigations into
  melanin as both a natural sunscreen and a metapho
 rical radioisotope for human evolution.  Although 
 assignations of “Negro” and “Caucasian” skin had l
 ong diffused the medical literature\, some dermato
 logists searched for constructive categories that 
 acknowledged the wide spectrum of skin tones withi
 n these assignations.  \n\nThe Fitzpatrick scale\,
  posited in 1975 and amended in 1988 and 2002 by H
 arvard dermatologist Thomas Fitzpatrick\, presente
 d a phototyping classification schema that ordered
  light and dark-skinned patients into six grouping
 s\, privileging photosensitivity/erythema and tann
 ing reactions over ethnoracial attachment.  This p
 romotion of a scale of difference that neatly side
 stepped previous biomedical constructions of “race
 ” built upon previous efforts to construct tools a
 nd metrics that did not rely on the subjectivity o
 f the human eye.  The co-development of colorimetr
 y\, spectrophotometry\, and UV-radiation treatment
 s to assess human skin color variation for treatme
 nt (rather than taxonomy) also offered new methods
  to investigate pigmentation disorders\, including
  vitiligo\, albinism\, and Addison’s disease.  The
  emergent intersections among photobiology and bas
 ic sciences lent much-needed authority to dermatol
 ogy\, helping to usher in its heightened status as
  a biomedical discipline that could weigh in on su
 n protection\, melanoma\, and human variety on bot
 h cellular and practical levels.\n
