SNSD's Yuri, Tiffany and Sooyoung were chosen to be the main models of Biotherm's cosmetic line, and more endorsement photos have been unveiled today. Unlike the last photo shoot which focused on the whitening effects, this time, it's all about moisturizing. Biotherm's manager Choi revealed, "It's difficult to get satisfactory pictures in this line unless you have the right skin for it. However, the three skin beauties' natural and adorable personality were expressed well. We are very satisfied." [gallery]
