Can i use bacitracin topical antibiotic for a cut on my skin while taking accutane?

Yes: But Bacitracin has not been shown to be of any value on any kind of wound. In experimental studies, those using vaseline or aquaphor healed the same or better than Bacitracin when used on surgical wounds. Bacithacin is a common sensitizer. A few years ago it was named the allergen of the year. Same for neosporin and triple antibiotic. Wash the cut, then keep it lubricated.
