This study was carried out to evaluate the antioxidant, anti-inflammation, and tyrosinase inhibitory activity of Melissa officinalis extracts and their fractions. The total polyphenol contents of the extracts were 33.02-302.76 mg GAE/g and total flavonoid contents were 9.98-325.07 mg CE/g. In 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging assay, DPPH radical scavenging activity was observed in the extracts and water fractions of M. officinalis and similar to that of ascorbic acid ($30{\mu}M$). In addition, the treatment of chloroform fraction significantly inhibited the production of nitric oxide (NO) in RAW 264.7 cells, indicating that they have anti-inflammatory activity. Tyrosinase inhibitory activity of $200{\mu}g/mL$ of 100% ethanol reflux extract showed better inhibitory activity than arbutin treatment at statistically significant level. As a result, it is considered that M. officinalis can be used as an effective cosmetic ingredient having antioxidant, anti-inflammation, and whitening activity.
