title: Telangiectasia of the face: risk factors for reappearance in patients treated with dye laser.
abstract: BACKGROUND
  Lasers can be successfully used in the treatment of facial telangiectasias. Nevertheless, reappearance of telangiectasias after successful laser treatment is a significant problem. Risk factors involved in the reappearance have not been previously investigated.
  
  
  OBJECTIVE
  To evaluate whether personal, clinical and behavioural factors can influence the recurrence or new appearance of telangiectasias after treatment.
  
  
  METHODS
  Four hundred and fifteen women and 69 men obtaining complete clearance after laser treatment were included in the study and the role of different risk factors in the reappearance of telangiectasias was analysed. Immunocompromised patients were excluded. A statistical analysis was then performed.
  
  
  RESULTS
  Twenty four percent of women and 14.5% of men enrolled showed a persistent clearance after treatment. In women in whom telangiectasias reappeared, logistic regression highlighted the importance of tanning addiction, aesthetic medicine and surgery procedures as risk factors, while therapy for menopause was found to be a protective factor. Hypertension was found to be a risk factor in men.
  
  
  CONCLUSIONS
  The efficacy of laser for treatment of telangiectasias of the face has been previously proven. Nevertheless, this is the first study presenting an analysis of risk factors involved in the new appearance of telangiectasias after the clearance induced by therapy.
