title: The influence of age and patient positioning on skin tension lines.
abstract: BACKGROUND
  The best cosmetic results are obtained if certain "skin lines" are followed. However, which "skin lines" are the correct ones has been controversial.
  
  
  OBJECTIVE
  To review the history of skin lines, the physiological basis of skin tension lines, and the factors that govern them.
  
  
  METHODS
  Twenty-seven individuals were observed, 15 greater than 65 years of age, and 12 less than 30 years of age. Patients were placed at 0 degrees and 90 degrees and the shift in skin tension lines was observed.
  
  
  RESULTS
  In older patients there was a significant shift in the skin lines with changes in positioning that was not present in the younger patients. In the older group of patients the shift in skin lines appeared to follow the direction of gravity's effect on the skin.
  
  
  CONCLUSIONS
  Skin tension lines in older patients may become movable with position changes and are not static as previously stated.
