AB |PrintPhototherapy  at  a  GlancePhototherapeutic  devices  have  varying  properties  with  respect  to  depth  of  UV  penetration  into  the  skin,  effects  on  cells  and  molecules,  potency,  side  effects  and  diseases  in  which  they  are  most  effective.In  use  today  are  narrowband  and  broadband  UVB,  UVA  as  part  of  psoralen  photochemotherapy  (PUVA),  UVA1  and  targeted  phototherapy  (excimer  lasers  and  nonlaser  monochromatic  excimer  light  sources).Narrowband  UVB  is  currently  preferred  to  treat  psoriasis,  other  inflammatory  skin  diseases,  and  vitiligo.Psoralen-UVA  photochemotherapy  (PUVA)  combines  oral  or  topical  psoralen  compounds  with  UVA  light  sources.  Its  main  uses  are  treatment  of  cutaneous  T-cell  lymphoma,  vitiligo,  and  psoriasis  that  is  resistant  to  narrowband  UVB.UVA1  phototherapy  is  particularly  effective  for  sclerotic  skin  diseases  such  as  localized  scleroderma,  acute  flares  of  atopic  dermatitis  and  urticaria  pigmentosa.Targeted  phototherapy  allowing  relatively  high  UV  doses  to  be  delivered  to  diseased  skin  while  sparing  normal  skin.
