On Sep. 4th, brand ambassador Zeng attended "optical magic opening ceremony" of Neutrogena. He answered questions from "new students" who encountered with acne problems and shared the new technique - red and blue lights to help them. He did an interesting presentation about elimination of acne by optical technique. He worn a white shirt with black trousers, which showed this sunny style. Zeng, who recently stays in filming sites, keeps his serious attitude about performance. His insistence on performance meets concept of Neutrogena very well.
