Water extracts of root, leaf, branch and fruit of Cudrania tricuspidata were tested to use as natural antiwrinkle and whitening cosmetic ingredient. Root extract indicated 86.5 mg/g polyphenol concentration and 55.5 mg/g flavonoid concentration. From MTT test, root, branch and fruit extract did not show cell toxicity up to $1,000{\mu}g/mL$, however, leaf extract displayed significant cell toxicity in concentrations higher than $200{\mu}g/mL$. Cudrania tricuspidata root extracts displayed excellent 81% tyrosinase inhibition (whitening effect), 58% elastase inhibition (antiwrinkle effect) at $500{\mu}g/mL$ and showed minor UVB absorbance. When solution and lotion formulation were made including Cudrania tricuspidata root extract, they are stable at $25^{\circ}C$ for 21 days, but showed significant deviation in viscosity and particle size at $47^{\circ}C$. From the study, Cudrania tricuspidata root extract demonstrated good potential for natural whitening and antiwrinkle cosmetic agent.
