Microbotox for the treatment of wide facial pores: A promising therapeutic approach.

Background: Microbotox is the injection of multiple microdroplets of diluted onabotulinum toxin A into the upper dermis. It has been previously used in one study only to decrease pore size and to improve skin texture.
Aims: To evaluate the efficacy and safety of microbotox in the treatment of wide facial pores.
Methods: Thirty-five patients with wide facial pores received a single session of microbotox. Objective measurements regarding improvement of pore size (0-4 scale) were recorded by two-blinded dermatologists. The improvements were confirmed by dermoscopic examination. Patient satisfaction was measured by Likert satisfaction scale (1-5 scale). Follow-up of the patients was done for 1 year.
Results: After a single treatment session, the total average of improvement was 87.2%. The average improvement of pore size was 3.7 (0-4 scale). The average patient satisfaction after the end of therapy was 4.7. Dermoscopic evaluation confirmed the reduction in the size and number of pores. There were no serious or long-term side effects.
Conclusions: A single treatment session of microbotox appears to be safe and effective for the reduction of facial pore size. Improvement of skin texture and oiliness was also observed.
