Authors: Young Sun Hwang, Youn-Jung Kim, Mi Ok Kim, Mingyeong Kang, Sae Woong Oh, Youn Hwa Nho, See-Hyoung Park, Jongsung Lee Published in Science Direct August 2017 Abstract Melanogenesis plays a critical role in the protection of skin against external stresses such as ultraviolet irradiation and oxidative stressors. This study was aimed to investigate the…
