Objective: Review the safety profi le and subjective effi cacy of intradermal botulinum toxin type A in facial pore size and sebum production.
Design: 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 satisfi ed with the procedure.
Conclusion: 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.
