"Eating cosmetic" market comes to prominence worldwide. Inner Beauty has established itself as the top trend nowadays and is leading the health functional food market. Another noticeable trend other than beauty-from-within is that products using "plant-based" natural botanical raw material are increasing. Based on these trends above, we have developed a plant extract named Agatri® for skin health using Agastache rugosa. By ingesting Agatri®, it is expected that the formation of skin wrinkles is suppressed, and skin elasticity is increased by suppressing the decrease in collagen content caused by ultraviolet rays. At the same time, it is possible to prevent skin aging by improving skin hydration and trans-epidermal water loss (TEWL). The studies show that it significantly increased production of hyaluronic acid and collagen, and decreased production of matrix metalloproteinases (MMPs). And Agatri® has been approved as an "Individually recognized functional ingredient for skin health by the Ministry of Food and Drug Safety, Korea in 2020. As a result, Agatri® is a good solution for those who are in need of skin protection from exposure to UV and aging.

The Spartina anglica is recognized as a highly invasive plant and active eradication methods are required. In this study, we aimed to determine the physiologic activities of Spartina anglica extracts as a cosmetic ingredient. Antioxidant properties were investigated by different chemical methods including radical quenching (DPPH and ABTS), reducing power(FRAP) assay and aerial part of S. anglica(SAA) extract presented the strongest antioxidant activities. The significant cytotoxicity was not observed up to a concentration of 0.5 mg/mL in RAW264.7 cells and NHDF cells. The anti-inflammatory activity of S. anglica belowground(SAB) extract had strong effects on cell-based systems, including LPS-induced NO and cytokines(TNF-a and IL-6) production in RAW264.7 cells. Collagen synthesis and skin hydration gene expression of S. anglica extract showed the highest anti-wrinkle and moisturizing effect in NHDF cells. Results presented in this study tend to show that the ethanol extracts of S. anglica could be exploited as useful-bio-resource for bioactive substances in functional cosmetics.

In this study, in an attempt to search for functional cosmetic ingredients from higher fungal, we have produced exopolysaccharides (GF-l, approximately carbohydrate 75％, protein 25％) and polysaccharide (GF-2) of mycelium extract, by submerged culture of Grifolafrondosa. For applications in anti-aging cosmetic field, we investigated the diverse biological activities. Antioxidant activity and inhibition of Matrixmetalloproteinases (MMPs) were investigated enzymatic assays by measuring the superoxide scavenging activity using xanthine-xanthine oxidase system and the proteolytic activity of MMPs using EnzChek Collagenase/Gelatinase kits, respectively. GF-l polysacchairde showed inhibition of superoxide radical by 90％ at a concentration of 0.2％ (w/v) and inhibition of collagenase by 45％ at 0.2％ (w/v). GF-2 polysaccharide of mycelium extract also exhibited good antioxidant activity. However, MMPs inhibition activity was relatively lower level compared to GF-l polysaccharides. The treatment of human dermal fibroblast (HDF) with GF-l and GF-2 polysaccharides increased the proliferation of fibroblast by approximately 23-25％ at a concentration of 0.5％ (w/v), also showed collagen synthesis increase in HDF by about 50％ at 0.5％ (w/v) compared to that of untreated control. We also report the moisturizing effects of polysaccharides in cosmetic products (O/W emulation) and its own ingredient, in vitro and in vivo. The GF-1 polysaccharide showed higher moisturizing ability than sodium hyaluronate, which is the most commonly used moisturizers ingredient. These results suggest the GF-l polysaccharide, protein-bound polysaccharide, may be used as an ingredient for new moisturizing and anti-aging cosmeceuticals.
