These days, the raw materials that have the cell recovering effect are used commonly in cosmetics. In this study, six materials were rested for the characteristics of recovering effect both on vivo and in vitro. Tested raw materials were Soypol, 3-APPA, Apple extract, Polygonatum japonicum extract, Scutellarkd baicalensis extract, Aloe extract. Among these materials, Soypol and 3-APPA were synthesized and others were made by extraction at the Pacific R&D Center. Human forearm skin and cultured skin cell were damaged by sodium lauryl sulfare and then raw materials were applied for open treatment on SLS damaged human skin or cells. The recovering effects of raw materials in vivo were evaluated by measuring transepidermal water loss, skin hydration and erythema and in vitro effects of proliferationg cells were assessed by neutral red uptake assay. In the in vivo study, only the evaluation by TEWL showed correlation with the visual score. Our of six materials, 3-APPA had the most positive effect in both in vivo and in vitro studies and the correlation was r=0.8286 (p=0.042).
