To evaluate safety of novel products for the cosmetic and pharmaceutical uses, various animal models have been conventionally used. However, in near future, all animal tests are scheduled to be banned in European cosmetic industry and therefore alternative skin toxicity tests should be required to evaluate the safety of newly introduced cosmetic ingredients. Currently, artificial epidermal equivalents or artificial skins are suggested to be used for skin irritation testing as alternative methods. However, it is practically impossible that the three dimensional tissue engineered products are introduced to the early developmental stages of active ingredients as a method for testing skin irritation due to their higher costs and low-throughputs in performance. In this regard, we are developing novel and high-throughput alternative test methods for evaluating skin irritation through the omics-based systems toxicology approaches. In preliminary results, in order to evaluate the feasibility to develop mechanism-based toxicity testings related to skin barrier, we evaluated the toxicological effect of Asian dust storm particles on transcriptional changes of skin barrier development-associated proteins. In addition, we studied the cosmeceutical whitening effect of kojic acid with a melanocyte-keratinocyte co-culture system to evaluate whether co-culture system is effective as an alternative testing system. Genome-wide transcriptional profiles for cosmetic ingredients, such as retinol, kojic acid, and UV filters, etc., have been evaluated in cultured normal human keratinocytes to discover novel toxicity biomarkers. In addition, to differentiate between pharmacological and toxicological components in omics data, we also performed genome-wide transcriptional profile studies for a representative skin irritant, sodium lauryl sulfate (SLS), and a skin sensitizer, urushiol in human keratinocytes. We will present current advancements of the omics-based development of novel alternative test methods for evaluating skin irritation as one of projects in the National Coordination Center for Global Cosmetic R&D.
