This study attempted to investigate the possibility of the use of Morinda citrifolia (MC) as a cosmetic ingredient from its physiological activities such as antioxidant activity, cytotoxicity and anti-aging effect. MC is a tropical plant that has been used as traditional polynesian foods and medicines for over two thousand years. It has been reported that this shrub can improve antimicrobial, anti-cancer and anti-inflammatory effects and strengthen an immune system. The in vitro antioxidant activity of MC was performed to see the DPPH scavenging activity by measuring total polyphenol content and total flavonoid content. As a result, a lack of any cytotoxicity was confirmed in human dermal fibroblasts (HDF) cell. When MC extract at a concentration of over 50 ∼ 100 μg/mL was added, MMP-1 expression considerably diminished. In an in vivo test, in addition, cream containing MC extract was prepared and applied to a total of 22 women in their 30 ∼ 50s in ages in the morning and in the evening for four weeks. Changes in keratin, melanin index, pore, skin color and wrinkles under the naked eyes were then comparatively measured. Keratin levels slightly increased in the control group but decreased in the experimental group. In addition, wrinkles diminished in the experimental group. This study found that MC extract controls many MMP-1 related mechanisms with great potential for use as a natural ingredient of anti-aging cosmetics.
