title: Sebum Secretion of the Trunk and the Development of Truncal Acne in Women: Do Truncal Acne and Sebum Affect Each Other?
abstract: BACKGROUND
  There are few published data on truncal acne because most studies have focused on facial acne.
  
  
  OBJECTIVE
  The objective of this study was to investigate truncal sebum secretion levels in patients with acne vulgaris and to evaluate the relationship between sebum secretion and the development of acne lesions.
  
  
  METHODS
  The sebum casual levels at five different facial sites and ten truncal sites were measured in 35 Korean females with acne using a Sebumeter®. We performed an analysis of the correlation between sebum excretion and acne lesion number.
  
  
  RESULTS
  We found that all of the truncal sites analyzed had lower sebum secretion levels than the facial sites. There was no significant correlation between sebum secretion and acne lesions on the trunk.
  
  
  CONCLUSIONS
  Pathogenic factors other than sebum may have a predominant role in the development of truncal acne.
