title: Use of intradermal botulinum toxin to reduce sebum production and facial pore size.
abstract: OBJECTIVE
  Review the safety profile and subjective efficacy of intradermal botulinum toxin type A in facial pore size and sebum production.
  
  
  METHODS
  Retrospective analysis of 20 patients.
  
  
  RESULTS
  Twenty consecutive patients with a single application of intradermal botulinum toxin type A were examined: Patients (17/20) noted an improvement in sebum production and a decrease in pores size at 1 month after injection. No complications were observed, and 17/20 patients were satisfied with the procedure.
  
  
  CONCLUSIONS
  Preliminary data suggests that intradermal botulinum toxin may play a role in decreasing sebum production. Further quantitive study may be necessary to determine effects of intradermal botulinum toxin on pore size.
