The purpose of the present research was to investigate the physiological activities of the thermal treated eggplant on the skin. Five minute of thermal treatment at $100^{\circ}C$ had the highest polyphenol content of eggplant. However, below and over 5 min of thermal treatment time, they did not increase. When water and ethanol extracts were used, the maximum DPPH radical scavenging activities were obtained, 66.3 and 62.8%, respectively. Among various extracts, the acetone extract gave the highest cosmetic activity. Especially, when acetone extract (15.0 mg/mL) was used, the maximum inhibition activities of tyrosinase, elastase, and collagenase were obtained, 83.4, 78.2 and 62.5%, respectively. These results suggest the anti-wrinkle and whitening and effects of acetone extract were excellent. Therefore, it is should be considered as a promising candidate for novel cosmetic agents.
