"Hyperpigmentation is difficult to treat, especially in dark-skinned individuals," said Dr. John Pawelek, senior researcher at Yale University. "If in-vitro models could be used to screen for potential inhibitors of pigmentation, this would represent a large step forward toward the development of truly effective treatments for this emotionally and socially challenging skin condition." Skin cancer research led by Dr. Pawelek has helped identify several novel aspects of the cell biology of melanocytes, the cells that synthesize the pigment melanin. Yale University and Amway have entered into an agreement with the intent to research and expand on these findings jointly. Initial research will focus on determining whether the unique cell biology of melanoctyes from human melanoma biopsy samples is also present in experimental models, including cell and tissue cultures. "Through our partnership, we hope to identify new technologies to enhance the performance of our ARTISTRY® whitening products," stated Catherine Ehrenberger, vice president, R&D and Quality Assurance for Amway. "We are looking forward to continuing our commitment to providing high-quality products that help women achieve their desired complexions."
