Bacteriological analysis of used and unused lipstick was carried out to identify bacterial associated with lipsticks. 8 samples were analyzed. (4 used lipstick and 4 un-used lipsticks). A total of fou r (4) bacterial isolates were identified; Staphylococcus aureus, Enterococcus spp. Escherichia coli and Streptococcus pyogenes. The percentage occurrence of bacterial isolated from used lipsticks was 70% while that from un-used samples were 30%. The result shows that there is more bacterial occurrence on the used samples than the un-used sample. The difference in the bacterial occurrence on the used lipstick sample may be due to unhygienic handling, raw materials, environmental condition, and sharing of lipsticks with others.
