The objective of this study was to evaluate the anti-melanogenic effects of crude polysaccharide fractions from Annona muricata L. (ALP) in 3-isobutyl-1-methylxanthine (IBMX) stimulating hormone-induced mouse B16F10 melanoma cells. The inhibitory effect of ALP on tyrosinase activity was approximately $33.88{\pm}0.79%$ at 5 mg/mL. Additionally, the B16F10 cellular tyrosinase and melanin synthesis inhibition activities by ALP were $54.21{\pm}4.76$ and $56.74{\pm}6.97%$ at $250{\mu}g/mL$, respectively. Similarly, whitening-related protein tyrosinase, tyrosinase-related protein 1 (TRP-1) and TRP-2, and microphthalmia-associated transcription factor (MITF) were reduced by ALP treatment. These results indicated that ALP could be used as a functional cosmetic ingredient after confirming its whitening activity related to melanin content.

In this study, Niacinamide (NI) was loaded into solid lipid nanoparticles (SLNs) and skin permeability was evaluated to improve skin permeability of NI, which was a skin whitening substance. NI was able to effectively load within SLN with a double-melting emulsification method, producing stable particles with average particle sizes of 263.30 to 436.93 nm and a zeta potential of -34.77 to -57.60 mV. Artificial skin tissue (SkinEthic^TM RHE) derived from skin keratinocytes derived from human epidermal tissue was used for the skin permeation study of NI. Skin transmittance and deposition experiments of NI confirmed that all SLN formulations improved skin transmittance and deposition rates of NI, approximately 5.4 ~ 7.6 and 9.5 ~ 20.8 improvement over SLN applications. Therefore, SLN manufactured in this study have shown sufficient results to improve the skin permeability of the functional whitening substance, NI.

The roots of reed (Phragmites australis) were used in traditional medicine to treat respiratory problems, including symptoms such as high fever and cough. In this study, we identified the active ingredient from 70% EtOH reed root extract, and evaluated the whitening, wrinkle improvement and moisturizing effects. The content of p-coumaric acid, the active ingredient of the roots of P. australis, was slightly lower in 70% EtOH extract than in 100% EtOH extract. However, 70% EtOH reed root extract showed similar or higher effect in reducing power, DPPH, hydrogen peroxide scavenging, and nitric oxide scavenging activity compared to 100% EtOH extract. Moreover, 70% EtOH reed root extract markedly inhibited melanogenesis in B16F10 cells treated with α-melanocyte-stimulating hormone. 70% EtOH reed root extract significantly inhibited the mRNA expression of matrix metalloproteinase-1 (MMP-1) and reduced elastase activity in HDF human dermal fibroblasts. In addition, 70% EtOH reed root extract ameliorated hyaluronic acid synthase-2 (HAS-2) expression induced by ultraviolet B (UVB) stimulation in HaCaT keratinocytes. The results of this study suggest that 70% EtOH reed root extract has potential as a functional cosmetic material related to whitening, wrinkle improvement, and moisturizing.

This study aimed at evaluating the potential of makgeolli, which is widely consumed as beverage, as a functional cosmetic ingredient, based on analyses on its antioxidant activity and tyrosinase activity inhibitory effect. The sample was extracted by concentrating the suspension obtained after adding MeOH (3 L) to the residue of a commercial makgeolli and then adding EtOAc (3 L) to the concentrate, which was subjected to fractionation. The upper layer of the fractions was used as the final sample. In MTT assay assessments, no cytotoxicity was observed at a concentration range of 10 to $1,000{\mu}g/mL$; the antioxidant activity of the extract showed a concentration-dependent tendency and it had a high activity with an $EC_{50}$ of 7.008 mg/mL. Also, in a tyrosinase activity inhibitory effect assessment, the extract showed an $IC_{50}$ value of 39.22 mg/mL. These results confirmed that this sample has potential as a functional cosmetic ingredient.

Eruca sativa (known as rocket plant) is a member of the Brassicaceae, which is considered an important chemo-preventive plant family. Although Eruca sativa has positive biological effects such as antioxidant and renal protective activities, the effect of the Eruca sativa extract as a therapeutic agent for skin whitening has not been reported. In this study, we investigated the applicability of the extract of Eruca sativa as a functional materials by examining the its physiological activities. The Eruca sativa extract showed low cytotoxicity against murine melanoma B16F10 cells. At concentrations (below 100 mg/L) that showed none or little cytotoxicity, the Eruca sativa extract showed high DPPH radical scavenging activity (ID50, 17.60 mg/L). In addition, the Eruca sativa extract inhibited tyrosinase activity ($ID_{50}$, 132.54 mg/L) and decreased melanin content ($ID_{50}$, 158.90 mg/L). Finally, the treatment with the Eruca sativa extract suppressed the protein expression of tyrosinase in a concentration-dependent manner. These findings suggested that the Eruca sativa extract inhibited melanin synthesis by not only suppressing intracellular tyrosinase expression but also directly inhibiting tyrosinase activity. Therefore, these results indicate that the Eruca sativa extract may be an effective material for functional cosmetics such as skin whitening materials.

Cooking drips which were obtained as by-product after seafood processing in the food industries, still contain lots of proteins, carbohydrates, and other functional materials. This study was conducted to investigate the effect of gamma irradiation on the biological activities of seafood cooking drips. When the cooking drips of Hizikia fusiformis, Enteroctopus dofleini and Thunnus thynnus were irradiated, the antioxidant activities, whitening effect, and angiotensin I converting enzyme inhibition activity of the ethanol extract from seafood cooking drips were all increased by gamma irradiation. This was because of the increased extraction efficiency of available compounds by irradiation. These results suggested that the seafood cooking drips, wasted as by-products, can be used as functional compounds with gamma irradiation treatment.

Ecklonia cava is popular in Korea as a marine functional materials. E. cava is generally collected and used on the coast of Jeju Island. However, the continuous use of collected natural E. cava may be limited because difficult to secure throughout the year and may be exposed to environmental pollution. Jeju magma seawater (MSW) was known to be significant advantages such as safety, cleanness, stability, and functional improvement. Attempts have been reported on application of MSW to the culturing of macro- and microalgae and showed improved results. Thus, the objective of the present study was to explore the anti-melanogenesis activity of brown seaweed E. cava (E. cava cultured with MSW [MSWE]) extract cultured in tanks with MSW of Jeju Island to evaluate the possibility of cosmeceutical industrial application. MSWE extract showed the higher polyphenolic and dieckol contents than natural E. cava (NE) extract. Anti-melanogenesis activity of MSWE extract and NE extract are tested and compared using tyrosinase and dihydroxyphenylalanine (DOPA) oxidation inhibition assay. MSWE extracts evidenced more effective tyrosinase and DOPA oxidation inhibition activity than that of the NE extracts and the commercial whitening agent, arbutin. MSWE extracts also markedly inhibited melanin synthesis and decreased the expression of melanogenesis-related protein in ${\alpha}$-melanocyte stimulating hormone-stimulated B16F10 melanoma cells without cytotoxicity. These results suggest that MSW cultivation process would be more effective in releasing bioactive compounds with whitening effect from seaweed such as E. cava at an industrial scale.

Marine resources have various biological activities and their constituents are more novel than those of land organisms. Several biologically active constituents have been found in marine organisms. Recently, many studies have reported that marine animals (MAs) can be used as functional ingredients in functional foods or nutraceutical due to their health benefits. However, no studies have extensively investigated the cosmeceutical activities of MAs extracts. Here, 70% ethanol extracts of 38 MAs were investigated for their activities of whitening and anti-aging properties for use as materials in novel cosmeceuticals. Anti-aging activities were determined by skin aging-related enzyme activities (anti-collagenase, anti-elastase, anti-hyaluronidase) and whitening activities (anti-tyrosinase, anti-3,4-dihydroxyl-L-phenylalanine [DOPA] oxidation) evaluated by colorimetric method. Among the 38 MAs, we found that Urechis unicinctus and Petrosia corticata extracts showed the strongest inhibitory effects against tyrosinase and DOPA oxidation, respectively. Our results additionally showed that Protankyra bidentata extract might provide a major source of anti-hyaluronidase and anti-elastase; meanwhile, anti-collagenase effects were similar in most MAs. Overall, these results suggest that extracts of marine animals have potential as a tyrosinase, collagenase, elastase, and hyaluronidase inhibitors. Taken together, MA resources could be considered as a novel cosmeceutical agent to be applied in cosmetic industry.

This study is peformed to investigate the effect of water extract from Vaccinium uliginosum L., on melanin production in B 16 melanoma cells, procollagen production and matrix metalloproteinase-1(MMP-1) inhibition in human fibroblast cells. One hundred grams of the Vaccinium uliginosum L. was extracted with 2000 mL of water($90^{\circ}C$, 16h, 2times). The water extracts were lyophilized and stored at $4^{\circ}C$ until used. Dry weight yields of extracts of Vaccinium uliginosum L. were $3\%$(w/w). Extracts from Vaccinium uliginosum L. showed scavenger activities on DPPH radical, superoxide anion radical, hydroxyl radical, hydrogen peroxide and singlet oxygen radical. And these substances inhibited release of cyiokines from human keratinocyte after UV B exposure. Therefore we confirmed that extracts from Vaccinium uliginosum L. had antioxidative effect. These substances inhibited purified tyrosinase activity and melanogenesis in B 16 melanoma cells treated/untreated IL-$1{\alpha}$. Moreover this extract stimulated procollagen production and inhibited MMP-1 production in human fibroblast cells treated/untreated IL-$1{\beta}$. Therefore we confirmed that extracts from Vaccinium uliginosum L. had whitening effect. And these substances decreased degree of wrinkle in hairless mouse skin that induced by UV B irradiation. Therefore we confirmed that extracts from Vaccinium uliginosum L. had anti-wrinkle effect. From the above results, it is possible that Vaccinium uliginosum L. may be developed to be an anti-melanogenesis agent and anti-wrinkle agent.
