Dendrobium moniliforme (DM) is a valuable and versatile herbal medicine with the anecdotal claims of antioxidant and anti-inflammation. In the present study, we investigated the whitening and anti-wrinkling effects of DM under various conditions with B16F10 melanoma cells and human dermal fibroblasts. The DM extract inhibited melanin contents and tyrosinase activity in a dose-dependent manner, compared with untreated group. Treatment of the DM extract effectively suppressed the ${\alpha}$-MSH-stimulated melanin formation, tyrosinase activity and dendrite outgrowth. Moreover, the ${\alpha}$-MSH-induced mRNA expressions of tyrosinase-related protein-1 (TRP-1) and tyrosinase-related protein-2 (TRP-2) and protein expression of tyrosinase were significantly attenuated by DM treatment. We also investigated the DM increased the production of type I procollagen and inhibited TNF-${\alpha}$-induced mRNA expressions of MMP-1, -3 in the human dermal fibroblast. These results indicate that DM may be a great cosmeceutical ingredient for its whitening and anti-wrinkle effects.

SZ95 cell is an immortalized human sebaceous gland cell line that shows the morphologic, phenotypic and functional characteristics of normal human sebocytes. Sebocytes may play crucial parts in the pathophysiologic processes and disorders of the pilosebaceous unit. The secretory activity of the sebaceous gland is remarkably species-specific and acne is an exclusively human disease. Thus, this SZ95 cells offer possibilities for investigations on the physiology of the sebaceous gland and its role in sebum-associated skin disease such as acne. In this study, we investigated the effects of 13-cis-retinoic acid (13-cis-RA) and spironolactone, frequently used as therapeutic agents of acne, on the lipid synthesis and proliferation of human sebocytes. Cell proliferation was determined by MTT assay and cytoplasmic lipid droplets was shown by Oil-red a staining. Total lipid levels were biochemically estimated by the sulfo-phospho-vanilline reagent. 13-cis-RA and spironolactone significantly inhibited proliferation and lipid levels in a dose-dependent manner. Combined treatment with testosterone and 13-cis-RA or spironolactone resulted in a lower total lipid levels than that with androgen alone. These observations indicate that 13-cis-RA and spironolactone are potent inhibitors of both cell proliferation and lipid synthesis in human sebocytes. We will provide experimental evidence that this human sebocyte cell line serves as an adequate tool for evaluating the anti-lipogenic activity of various compounds potentially useful for the bioactive cosmeceutical ingredients on acne skin, and studying the intracellular biochemical markers depending on the types of compounds from various sources.

Retinyl palmitate (RP)-loaded pectinate micro- and nano-particles (PMP and PNP) were designed for stabilization of RP that is widely used as an anti-wrinkle agent in anti-aging cosmeceuticals. PMP/PNP were prepared with an ionotropic gelation method, and anti-oxidative activity of the particles was measured with a DPPH assay. The stability of RP in the particles along with pectin gel and ethanolic solution was then evaluated. In vitro release and skin permeation studies were performed using Franz diffusion cells. Distribution of RP in each skin tissue (stratum corneum, epidermis, and dermis) was also determined. PMP and PNP could be prepared with mean particle size diameters of $593{\sim}843{\mu}m$ (PMP) and 530 nm (i.e., $0.53{\mu}m$, PNP). Anti-oxidative activity of PNP was greater than PMP due largely to larger surface area available for PNP. The stability of RP in PMP and PNP was similar but much greater than RP in pectin bulk gels and ethanolic solution. PMP and PNP showed the abilities to constantly release RP and it could be permeated across the model artificial membrane and rat whole skin. RP was serially deposited throughout the skin layers. This study implies RP loaded PMP and PNP are expected to be advantageous for improved anti-wrinkle effects.

Dendrobium loddigesii (DL) is a valuable and versatile herbal medicine with the anecdotal claims of anti-oxidant and anti-inflammation. In the present study, we investigated the whitening effects of DL under various conditions with B16F10 melanoma cells. The DL extract inhibited melanin contents and tyrosinase activity in a dose-dependent manner, compared with untreated group. Treatment of the DL extract effectively suppressed the ${\alpha}$-MSH-stimulated melanin formation, tyrosinase activity and dendrite outgrowth. Moreover, the ${\alpha}$-MSH-induced mRNA expressions of tyrosinase-related protein-1 (TRP-1), tyrosinase-related protein-2 (TRP-2), microphthalmia-associated transcription factor (MITF) and protein expression of tyrosinase were significantly attenuated by DL treatment. These results indicate that DL may be a great cosmeceutical ingredient for its whitening effects.

In the present study, the alcoholic and enzymatic extracts of Ecklonia maxima were prepared and their antioxidant activities were evaluated via the free radical scavenging activities. The lyophilized seaweed powder was extracted by 70% ethanol and the resultant extract was obtained, named as the alcoholic extract of E. maxima stem (EMSE) obtained. The residue after EMSE preparation was continuously by Celluclast-assistant extraction and then the obtained enzymatic extract was identified as polysaccharides-rich extract of E. maxima stem (EMSP). The results indicated that the extraction yields of EMSE and EMSP were 2.18% and 5.43%, respectively. In addition, the free radical scavenging activities of EMSE and EMSP were determined using an electron spin resonance (ESR) spectrometer. EMSE containing 5.36% of polyphenol and 1.56% of polysaccharide scavenged DPPH and alkyl radicals at the $IC_{50}$ values of 0.48 and 0.63 mg/mL, respectively. EMSP containing 0.33% of polyphenol and 41.58% of polysaccharide showed at the $IC_{50}$ values of 0.33 and 0.55 mg/mL, respectively. These results demonstrate that EMSP containing a high amount of polysaccharides possesses a strong free radical scavenging activity which might be a potential ingredient in pharmacological and cosmeceutical industries.

Background: BIOGF1K, a compound-K-rich fraction, has been shown to display anti-inflammatory activity. Although Panax ginseng is widely used for the prevention of photoaging events induced by UVB irradiation, the effect of BIOGF1K on photoaging has not yet been examined. In this study, we investigated the effects of BIOGF1K on UVB-induced photoaging events. Methods: We analyzed the ability of BIOGF1K to prevent UVB-induced apoptosis, enhance matrix metalloproteinase (MMP) expression, upregulate anti-inflammatory activity, reduce sirtuin 1 expression, and melanin production using reverse transcription-polymerase chain reaction, melanin content assay, tyrosinase assay, and flow cytometry. We also evaluated the effects of BIOGF1K on the activator protein-1 signaling pathway, which plays an important role in photoaging, by immunoblot analysis and luciferase reporter gene assays. Results: Treatment of UVB-irradiated NIH3T3 fibroblasts with BIOGF1K prevented UVB-induced cell death, inhibited apoptosis, suppressed morphological changes, reduced melanin secretion, restored the levels of type I procollagen and sirtuin 1, and prevented mRNA upregulation of MMP-1, MMP-2, and cyclo-oxygenase-2; these effects all occurred in a dose-dependent manner. In addition, BIOGF1K markedly reduced activator-protein-1-mediated luciferase activity and decreased the activity of mitogen-activated protein kinases (extracellular response kinase, p38, and C-Jun N-terminal kinase). Conclusion: Our results strongly suggest that BIOGF1K has anti-photoaging activity and that BIOGF1K could be used in anti-aging cosmeceutical preparations.

본 연구는 향부추의 알뿌리, 잎, 꽃 등의 세 부위별 에탄올 추출물을 대상으로 항산화와 항염 효능을 평가하였다. DPPH와 ABTS 라디컬 소거능 결과, 알뿌리와 잎보다 꽃 추출물의 소거 활성이 높게 나타났으며 FRAP 분석결과 모든 추출물에서 추출물 농도 의존적으로 항산화 활성이 증가하였다. 총 폴리페놀 함량은 꽃 (11.29±0.37 mgGAE/g) > 잎 (6.61±0.14 mgGAE/g) > 알뿌리 (5.7±0.67 mgGAE/g) 추출물 순으로 높게 검출되었다. 쥐 대식세포 RAW264.7 세포와 사람 피부각질 세포주 HaCaT 세포에 대한 세 가지 추출물의 세포독성은 거의 나타나지 않았다. NO비색정량법, ELISA를 통하여 각 추출물의 항염 효능을 조사한 결과 LPS에 의한 NO 생성, TNF-α 분비가 꽃 에탄올 추출물에서 유의한 수준으로 감소하였다. 따라서 이러한 결과들은 천연식물 자원인 향부추의 에탄올 추출물이 화장품 원료로서 높은 가능성을 의미한다.
