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

Abstract 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.
