“Effect of Camellia japonica oil on human type I procollagen production and skin barrier function. In this study, we investigated the possibility that Camellia japonica oil (CJ oil) may be introduced as an anti-wrinkle agent…  based on these results, we suggest the possibility that CJ oil may be considered as possible wrinkle-reducing candidates for topical application.” http://www.ncbi.nlm.nih.gov/pubmed/17386986

“Inhibitory effects of natural plants of Jeju Island on elastase and MMP-1 expression. In order to search for new active cosmetic ingredients of natural origin, we screened about 60 plants collected from Jeju Island, which is located in the southernmost part of the Republic of Korea… four extracts, including… Camellia japonica (leaf), completely inhibited the expression of MMP-1 in human fibroblast cells. The results showed that four of the 60 plant extracts may hold potential for use as natural active ingredients for anti-aging cosmetics.” http://www.ncbi.nlm.nih.gov/pubmed/17342265

“Melanogenesis inhibitory and fibroblast proliferation accelerating effects of noroleanane- and oleanane-type triterpene oligoglycosides from the flower buds of Camellia japonica. Camellioside B (2), a major constituent of C. japonica grown in Japan, showed potent inhibition of melanogenesis… Interestingly, camellioside B (2) significantly accelerated fibroblast proliferation. This biological selectivity could make camellioside B useful for treating skin disorders…”  http://www.ncbi.nlm.nih.gov/pubmed/22834923

“Inhibitory effects of an ellagic acid glucoside, okicamelliaside, on antigen-mediated degranulation in rat basophilic leukemia RBL-2H3 cells and passive cutaneous anaphylaxis reaction in mice. Degranulation inhibitors in plants are widely used for prevention and treatment of immediate-type allergy. We previously isolated a new ellagic acid glucoside, okicamelliaside (OCS), from Camellia japonica leaves for use as a potent degranulation inhibitor… These results suggest the potential for OCS to alleviate symptoms of immediate-type allergy.” http://www.ncbi.nlm.nih.gov/pubmed/22330086
