Latest Insights into Skin Hyperpigmentation

Hyperpigmentary problems, including postinflammatory hyperpigmentation, solar lentigos, and melasma, occur widely in the human population and are thus of broad interest for control. On the basis of genomic and proteomic understanding of the melanocyte and melanogenesis, there are potentially hundreds of proteins and other effectors involved in pigmentation. This knowledge, although complex, should prove most useful in identifying specific abnormalities that lead to the hyperpigmentary problems. Also available are new laboratory screening methods and skin color measurement tools that are increasing the pace at which materials can be screened and evaluated clinically for their effectiveness. Combined with a clear consumer need for effective pigmentation control agents, advanced pigmentary system understanding and new research capabilities are setting the stage for future technological advancements
