In this study, cosmeceutical activities of the co-cultures of both lactic acid bacteria isolated from the hands of women, Lactobacillus rhamnosus (L. rhamnosus) and Lactobacillus paracasei (L. paracasei) were first reported: For whitening and anti-wrinkle activities, the co-culture showed the highest tyrosinase inhibition of 20.68%, compared L. paracasei and L. rhamnosus. The co-culture also showed the highest inhibition of melanin synthesis as 63.7%. In observing the anti-wrinkle activities of the co-culture, it generated only 3726.3 pg/mL of matrixmetalloproteinase-1 (MMP-1) production when 13613.5 pg/mL and 13012.0 pg/mL of MMP-1 production were estimated from L. rhamnosus and L. paracasei. Besides these, the extract from the co-culture yielded higher collagen production as 380.7 ng/mL, compared to 323.4 ng/mL and 304.1 ng/mL from L. paracasei and L. rhamnosus. These results indicate that the co-culture of both lactic acid could improve its cosmetic activities. This hypothesis was also confirmed that the co-culture of both bacteria showed strong antioxidant activities of DPPH free radical scavenging while the extract of L. rhamnosus and L. paracasei.

We evaluated the physiological effects of formulations added with black garlic extract on skin care. Black garlic was made by spontaneous fermentation for 40 days at $60{\sim}70^{\circ}C$ and 85~95% RH without any additives. When black garlic extract was added to formulation, the tyrosinase activity was decreased significantly (p<0.05, p<0.01, p<0.001). Base formulation inhibited slightly elastase activity (<5%), while black garlic formulation had about 8-fold higher elastase inhibitory activity (p<0.01). It was observed that formulations, with or without black garlic extract, decreased thiobarbituric acid reactive substances (TBARS) and hydrogen peroxide which were increased by UVB irradiation, although there were no significant differences of these contents between black garlic formulation and base formulation. In conclusion, black garlic formulation had high inhibitory activities for tyrosinase and elastase, suggesting that black garlic may have beneficial properties as a material for cosmeceuticals.

The solvent extracts of Prunus persica Flos were investigated for the activities of anti-oxidant and anti-inflammation to apply as a functional ingredient for cosmetic products. The electron donating ability of both ethanol (PPE) or acetone (PPA) extracts of P. persica Flos was above 90.0% at the concentration of 500ppm. The superoxide dismutase (SOD)-like activity of P. persica Flos extracts (PPE, PPA) were approximately 40.0% at 1,000 ppm. The xanthine oxidase inhibitory effect of P. persica Flos extracts (PPE, PPA) was approximately 30.0% at 1,000 ppm and equivalent to that of ascorbic acid. Hyaluronidase inhibition activity related to the anti-inflammation effect was 35.0% with the treatment of P. persica Flos extracts (PPW, PPE, PPA) at 1,000 ppm, respectively. In the experiment of anti-inflammation effect, P. persica Flos extracts (PPW, PPE, PPA) inhibited the generation of nitric oxide. In the antimicrobial activity test against the human skin-resident microflora such as Staphylococcus epidermidis and Propionibacterium acnes, a clear zone was identified from 4mg/disc in P. persica Flos (PPE) extract.

The extracts of Agrimonia pilosa L. were investigated for the inhibitory effect on the melanin synthesis in B16/F10 mouse melanoma cells as a functional ingredient for cosmetic products. Tyrosinase inhibition activities were 42% in A. pilosa L. 70% ethanol extract at $500{\mu}g/mL$. The protein and mRNA expression of tyrosinase, which are all skin-whitening related factors, showed that A. pilosa L. water and A. pilosa L. 70% ethanol extracts inhibited the protein bio-synthesis in B16F10 melanoma cell. Results indicate that the A. pilosa L. extracts tested in the present study have skin whitening activity and can be used as a functional ingredient for cosmetic compositions.

To evaluate whether active components produced by solid fermentation of Phellinus baumii and Ephedra sinica have potential in ameliorating allergic symptoms in mice, we tested anti-allergic activities in a dinitrofluorobenzene (DNFB)-induced allergic mouse model. DNFB-induced allergic symptoms werereduced to about 50% of control levels by active components produced by solid fermentation of Phellinus baumii and Ephedra sinica, as evaluated by measuring the width of epidermal swelling. H&E staining also revealed that these active components markedly reduced allergic symptoms in the epidermis of the ear. The results indicate that active components produced by solid fermentation of Phellinus baumii and Ephedra sinica have the potential to ameliorateallergic symptoms, and may be useful biomaterial(s) in the neutraceutical or cosmeceutical industry.

The objective of this study was to evaluate the potential use of ginseng leaf as a cosmetic material. In this research, we employed enzymatic treated ginseng leaf by using Ultraflo L to improve the recovery of ginsenosides from the ginseng leaf and studied the biological activities and skin safety of the enzymatic treated ginseng leaf for use as a cosmetic material. The total ginsenoside contents of the non-enzymatic treated ginseng leaf (NEGL) and Ultraflo L treated ginseng leaf (UTGL) were 271 and 406 mg/g, respectively. The level of metabolite ginsenosides (sum of Rg2, Rg3, Rg5, Rk1, compound K, Rh1, Rh2, and F2) was higher in UTGL (93.1 mg) compared to NEGL (62.4 mg) in one gram ginseng leaf extract. The increase in amounts of ginsenoside types in UTGL compared to NEGL was generally 140% to 157%. UTGL exhibited relatively higher 2,2-diphenyl-2-picrylhydrazyl hydrate ($IC_{50}$, 2.8 mg/mL) and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt ($IC_{50}$, 1.6 mg/mL) radical scavenging activities compared to NEGL (4.8 mg/mL and 2.2 mg/mL). The UTGL group showed normalized hydrogen peroxide, lipid peroxidation and visual wrinkling grade induced-UVB exposure. The UTGL did not induce any adverse reactions such as erythema and edema on intact skin sites; however, some guinea pigs treated with UTGL on abraded skin sites showed very slight erythema. The primary irritation index (PII) score of UTGL was 0.05 and it was classified as a practically non-irritating material (PII, 0 to 0.5). In skin sensitization tests with guinea pigs, UTGL had a positive rate of skin sensitization at 40%, and the mean evaluation score was 0.4.

Due to the unique sourness and sweet taste of Aronia, it is necessary to develop it for processing rather than raw. The antioxidant activity and cytotoxin about the aronia powder fermentation extract using lactobacillus are verified. In the case of total polyphenol content, the content of non-fermented extract was 32.15 ㎍/mg fermentation extract, 43.08 ㎍/mg after fermentation, and the flavonoid content was 0.47 ㎍/mg in non-fermented extract and 0.44 ㎍/mg in fermented extract, which was similar to that of non-fermented extract. In the DPPH radical inhibition assay, 77.5% of the non-fermented extract and 89.1% of the fermented extract showed better activity than the non-fermented extract. Nitric oxide (NO) measurement showed a concentration-dependent inhibitory effect. From the above results, it was confirmed that the fermentation of Aronia powder could be utilized based on some antioxidant activities and the possibility of using it as a vegetable extract and fermented cosmetic material in the future.

The objective of the present study was to evaluate the skin whitening effect of the extracts of 3 herbs, Ligularia fischeri, Solidago virga-aurea and Aruncus dioicus, which were collected from Ullung island. Tyrosinase inhibition activities were 33% in pre-fermented extracts and 45% in post-fermented ones. When tyrosinase activities in B16F10 murine melanoma cells were tested, activities in pre- and post-fermented extracts were 41 and 56.5%, respectively. Thus, the post-fermented extracts might have greater skin whitening effects. The protein expression of MITF, TRP-1, TRP-2, and tyrosinase, which are all skin-whitening related transcription factors, showed that both pre- and post-fermented herbs inhibited protein biosynthesis in B16F10 melanoma cells. Post-fermented herb extracts especially showed a greater decrease of protein expressions. The expression of MITF, a regulatory transcription factor, was also decreased by both extracts but was greater in the post-fermented ones. From the results, it can be concluded that the 3 herb extracts from Ullung island may inhibit melanin biosynthesis by the suppression of MITF activity in a signaling pathway. Results indicate that the post-fermented herbs tested in the present study had skin whitening activities and can be used as functional ingredients for food and cosmetic compositions.

The extracts from Salvia officinalis were studied for antioxidative activities and inhibitory activities against angiotensin converting enzyme(ACE) and xanthine oxidase (XOase). Total phenolic compounds were found as 22.28, 26.3, 24.63, and 28.22 mg/g in the water, 60% ethanol, 60% methanol and 60% acetone extracts, respectively. The antioxidant activities of Salvia officinalis extracts were measured as $64.4{\pm}1.5%$ at $200\;{\mu}g/ml$ on EDA, inhibition rate on ABTS of $96.9{\pm}0.2%$, antioxidant protection factor of $2.30{\pm}0.16$ PF and TBARS was $0.6{\pm}0.05$ (${\times}100\;{\mu}M$) in the control and $0.28{\pm}0.02$ (${\times}100\;{\mu}M$) in 60% ethanol extracts. Inhibitory activities was the ACE of 75.50% and XOase 100% in 60% ethanol extracts. The 60% ethanol extracts from Salvia officinalis exhibited antimicrobial activities against Helicobacter pylori such as 13 mm of clear zone and inhibition rate of 63.4% with $200\;{\mu}g/ml$ of phenolics content. Rosemarinic acid was the most abundant phenolic compounds as analyzed by HPLC. The results suggest that the 60% ethanol extracts from Salvia officinalis L. will be useful as natural antioxidants and functional foods.

This study investigated the antioxidant activities, whitening effects, and antimicrobial activities of fractions from Pleurospermum kamtschaticumin extract. Total polyphenolic contents of fractions from Pleurospermum kamtschaticumin extract were 116.44~382.73 mg/g GAE (gallic acid equivalent), with the highest value in the ethyl acetate fraction. Fractions of Pleurospermum kamtschaticumin showed the highest DPPH (1,1-diphenyl-2-picrylhydrazyl) radical scavenging activity ($IC_{50}$=0.04 mg/mL) and ABTS radical scavenging activity (98.86% at 0.5 mg/mL), which was similar to ascorbic acid. Further, reducing power and FRAP activity were significantly high in the ethyl acetate and n-butanol fractions. The ethyl acetate and n-butanol fractions showed significantly high SOD-like activities (1 mg/mL, 86.93%, and 78.23%, respectively) compared to other fractions. Tyrosinase inhibition activities of the n-butanol fraction and 80% ethanol extract were 43.52% and 41.64%, respectively. Antimicrobial activity against Escherichia coli was only observed in the chloroform fraction (16.7 mm in 0.5 mg/disc). These results suggest that fractions from Pleurospermum kamtschaticumin extract show comparatively high antioxidant activity and thus could be used as a food additive or cosmeceutical ingredient.
