Recently, several researchers have been developing cosmetics from natural ingredients for skin whitening and anti-aging products. The red sea cucumber (RSC), Apostichopus japonicas, is a species of sea cucumber in the family stichopodiae, which is widely distributed in China, Japan, and Korea. To use Red Sea Cucumber as a cosmetic ingredient, its inhibitory effects on melanogenesis and the anti-aging effects of RSC extracts were investigated. First, a tyrosinase activity assay was performed, which showed that RSC inhibited tyrosinase activity at a concentration of $200{\mu}g/ml$. An MTT assay was carried out to evaluate cell toxicity, and the results showed that RSC extract has no cytotoxicity in HaCaT cells. Furthermore, the mRNA expression levels of tyrosinase, tyrosinase related protein 1 (TRP-1), tyrosinase related protein 2 (TRP-2), microphthalmia-associated transcription factor (MITF), and matrix metalloproteinase (MMPs) genes treated with RSC extract in B16F10 and HaCaT cells decreased. Moreover, a wound-healing assay was performed to identify the cell regeneration effect of RSC extracts. Also, a skin turnover effect was confirmed by creating a three-dimensional cell culture with HaCaT and human fibroblasts. Altogether, the results suggested that Red Sea Cucumber may possess a high ability to induce whitening and anti-wrinkle effects as a cosmeceutical ingredient.

Fructose-1, 6-diphosphate (FOP), a glycolytic metabolite is reported to ameliorate inflammation and inhibit the nitric oxide production in murine macrophages stimulated with endotoxin. It is also reported that FOP has cytoprotective effects against hypoxia or ischemia/reperfusion injury in brain and heart. In this study, we examined whether FDP has protective effects on UV-induced oxidative damage in skin cell culture system and human skin in vivo. FDP had a protective role in UVB-induced LDH release and ROS accumulation in HaCaT although it did not show direct radical scavenging effect in the experiment using 1, 1-diphenyl-2-picrylhydrazyl (DPPH). FDP also preserved cellular GSH content after UV irradiation in HaCaT and normal human fibroblast culture system. Cellular oxidative stress induces multiple downstream signaling pathways that regulate expression of multiple gene including MMP-1 and collagen, we examined the effects of FDP on UV-induced alteration of these protein expression in fibroblast culture and human skin in vivo. The increased MMP-1 expression in fibroblast and human skin by UV irradiation was significantly decreased by FDP. FDP also prevented the UV-induced decrease of collagen expression in fibroblast and human skin. Moreover, the decreasing the intracellular levels of reducing equivalents in human fibroblast by glutathione (GSH) depletion lowered the UVA dose threshold for reduction of procollagen expression, indicating that the differences of glutathione contents define the susceptibility of fibroblasts towards UV-induced reduction of procollagen expression. FDP also preserved cellular GSH content after UV irradiation, indicating that FDP has protective effects on UV-induced reduction of procollagen expression, which are possibly through maintaining intracellular reducing equivalent. Based on these premises, we examined the effect of daily use of a moisturizer containing FDP on facial wrinkle in comparison with vehicle moisturizer lacking FDP. In the clinical study, FDP significantly decreased facial wrinkle compared with vehicle alone after 6 months of use. Our results suggest that FDP has anti-aging effects in skin by increasing cellular antioxidant system and preventing oxidative signal and inflammatory reaction. Therefore FDP may be useful anti-aging agent for cosmetic purpose.

This study attempted to investigate the possibility of the use of Morinda citrifolia (MC) as a cosmetic ingredient from its physiological activities such as antioxidant activity, cytotoxicity and anti-aging effect. MC is a tropical plant that has been used as traditional polynesian foods and medicines for over two thousand years. It has been reported that this shrub can improve antimicrobial, anti-cancer and anti-inflammatory effects and strengthen an immune system. The in vitro antioxidant activity of MC was performed to see the DPPH scavenging activity by measuring total polyphenol content and total flavonoid content. As a result, a lack of any cytotoxicity was confirmed in human dermal fibroblasts (HDF) cell. When MC extract at a concentration of over $50{\sim}100{\mu}g/mL$ was added, MMP-1 expression considerably diminished. In an in vivo test, in addition, cream containing MC extract was prepared and applied to a total of 22 women in their 30 ~ 50s in ages in the morning and in the evening for four weeks. Changes in keratin, melanin index, pore, skin color and wrinkles under the naked eyes were then comparatively measured. Keratin levels slightly increased in the control group but decreased in the experimental group. In addition, wrinkles diminished in the experimental group. This study found that MC extract controls many MMP-1 related mechanisms with great potential for use as a natural ingredient of anti-aging cosmetics.

In this study, we prepared fractions from Cynanchum paniculatum (C. paniculatum) with ethyl acetate and identified the structure and content of paeonol, an indicator substance. Fractions were obtained by sequential solvent fractions using n-hexane, methylene chloride, ethyl acetate, n-butanol, and distilled water, and showed the highest paeonol content in ethyl acetate (EtOAc). The structure of the ethyl acetate fraction (EA) was confirmed by nuclear magnetic resonance (NMR) and the content was determined by high performance liquid chromatography (HPLC) analysis. The antioxidant activity of EA was tested through its ability to scavenge 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS), and its ability to inhibit nitric oxide (NO) production in RAW 264.7 cells induced by lipopolysaccharide (LPS) was tested for its ability to inhibit NO production in a concentration-dependent manner. Furthermore, MMP-1 production induced by ultraviolet B (UVB) was decreased in a concentration-dependent manner by the EA, and the ability to produce procollagen type-I was increased in a concentration-dependent manner. In addition, as a result of conducting clinical trials using cosmetic formulations containing EA, the effect of improving wrinkles around the eyes was confirmed. Thus, it is expected that Cynanchum paniculatum can be used as a natural functional cosmetic material with antioxidant and anti-aging effects.

Objectives: Based on data from Chinese and Indian traditional herbal medicines, gum resin of Ferula assa-foetida (sometimes referred to asafetida or asafoetida) has several therapeutic applications. The authors of various studies have claimed that asafetida has cytotoxic, antiulcer, anti-neoplasm, anti-cancer, and anti-oxidative effects. In present study, the anti-aging effect of asafetida on senescent human dermal fibroblasts was evaluated. Methods: Senescence was induced in in vitro cultured human dermal fibroblasts (HDFs) through exposure to $H_2O_2$, and the incidence of senescence was recognized by using cytochemical staining for the activity of ${\beta}$-galactosidase. Then, treatment with oleo gum resin of asafetida was started to evaluate its rejuvenating effect. The survival rate of fibroblasts was evaluated by using methyl tetrazolium bromide (MTT) assays. Real-time quantitative reverse transcription-polymerase chain reaction (qRT-PCR) and western blot assays were performed to evaluate the expressions of apoptotic and anti-apoptotic markers. Results: Our experiments show that asafetida in concentrations ranging from $5{\times}10^{-8}$ to $10^{-7}g/mL$ has revitalizing effects on senescent fibroblasts and significantly reduces the ${\beta}$-galactosidase activity in these cells (P < 0.05). Likewise, treatment at these concentrations increases the proliferation rate of normal fibroblasts (P < 0.05). However, at concentrations higher than $5{\times}10^{-7}g/mL$, asafetida is toxic for cells and induces cell death. Conclusion: The results of this study indicate that asafetida at low concentrations has a rejuvenating effect on senescent fibroblasts whereas at higher concentrations, it has the opposite effect of facilitating cellular apoptosis and death.
