Korean ginseng(Panax Ginseng C.A. Meyer) known as a oriental miracle drug is an important medicinal plant. Ginseng has been used for geriatric, tonic, stomachic, and aphrodisiac treatments for thousands years. Also, it is an antibiotic and has therapeutic properties against stress and cancer. Ginseng is widely distributed all over the world. Among them, Korean mountain ginseng has the most valuable effect on pharmaceuticals. The roots of mountain ginseng contained several kinds of ginsenosides that have many active functions for the human body. However, the study of mountain ginseng has a limit because the mountain ginseng is very expensive and rare. So, we artificially cultured mountain ginseng adventitious roots using the bioreactor culture system. We induced callus from original mountain ginseng, directly dug up in mountain and aged about one hundred ten years. Separated adventitious roots were precultured in 500ml conical flasks and then, transferred in 20L bioreactors. The adventitious roots of mountain ginseng were harvested after culturing for 40days, dried and then, extracted with several solvents. In this study, we investigated the whitening effect, anti-wrinkle effect and the safety of tissue cultured adventitious roots extract of mountain ginseng in order to identify the merit as a cosmetic ingredient. Particularly, extract of mountain ginseng adventitious roots showed whitening and anti-wrinkle effects. The inhibitory effect of this extract on the melanogenesis was examined using B-16 melanoma cell. When B-16 melanoma cells were cultured with adventitious root extract, there was a dramatically decrease in melanin contents of 8-16 melanoma cell. And we identified this extract inhibited Dopa auto-oxidation significantly. Also, when transformed mouse fibroblast L929 cells were treated with this extract, there was a significant increase in collagen synthesis. The results show significant inhibited melanization and wrinkle without inhibiting cell viability.

Objective : The purpose of this study was to evaluate the effect of korean herbal cosmetics for facial skin elasticity. Methods : We recruited patients and divided them to cosmetics group and control group randomly. We provided korean herbal cosmetics to cosmetics group and subjects in cosmetics group applied the provided cosmetics for 4 weeks. Control group waited and applied cosmetics that had previously used for 4 weeks. We assessed all subjects in 0 week, 2 weeks and 4 weeks. Primary assessment instrument was moire topography photo scale. Second assessment instrument was skin moisture, oiliness and elasticity which assessed with skintouch system v1.0, detox/regeneration questionnaire score and self-evaluating facial wrinkle/looseness score. Result : Moire topography photo scale improved in cosmetics group than control group significantly. Skin moisture and elasticity assessed with skintouch system improved in cosmetics group than control group significantly while skin oiliness assessed with skintouch system have not improved significantly. Detox/regeneration questionnaire score and self-evaluating facial wrinkle/looseness score improved in cosmetics group than control group significantly. Conclusion : Korean herbal cosmetics application might be effective method for facial skin elasticity.

From March 1, 2017 to May 31, 2017, subjects were allowed to apply a wrinkle-improving herbal cosmetic product containing the extract of Douchi for 8 weeks. The effectiveness of herbal cosmetics was evaluated through wrinkle improvement efficacy parameter analysis, subjective wrinkle improvement through questionnaires, and adverse reaction. The herbal cosmetic products containing the extract of Douchi showed a significant decrease in the wrinkle improvement efficacy parameter analysis result. The results of the subjective satisfaction analysis after use were also evaluated positively. We could confirm the possibility of wrinkle improvement effect of Douchi extract, and it will be possible to contribute to the expansion of korean medicine field through more studies in the future.

Vaccinium uliginosum L. (VU) is a flowering plant in the genus Vaccinium has berry fruit. This study was performed to investigate the effect of water extract of Vaccinium uliginosum L. and fractions on inhibition of melanogenesis and wrinkle formation. One hundred grams of the Vaccinium uliginosum L. was extracted with 2,000 mL of water ($90^{\circ}C$, 16h, 2 times). The water extracts were lyophilized and stored at $4^{\circ}C$ until used. Vaccinium uliginosum L. extracts showed scavenger activities on DPPH radical, superoxide anion radical, hydroxyl radical, hydrogen peroxide and singlet oxygen radical, dose dependently. And VU extract and fractions reduced melanin contents on B16F10 melanoma and inhibited the expression of melanogenesis-related proteins, tyrosinase, tyrosinase-related protein (TRP-1) and dapachrometa utomerase (Dct, TRP-2). Moreover VU extract and fractions stimulated procollagen production and inhibited MMP-1 production in human fibroblast. And it decreased degree of wrinkle formation in hairless mouse skin that induced by DVB irradiation for 9 weeks. From the above results, it is possible that Vaccinium uliginosum L. may be developed to be the health functional food and functional cosmetics that have anti-melanogenesis and anti-wrinkle effect.

This paper described the formulation of functional cosmetics and evaluation of anti-wrinkle efficacy in clinical test. Cosmetics were formulated with highly purified $\beta$-carotene obtained from the culture broth of recombinant E.coli cells. Edible oil for solubilizing $\beta$-carotene, vitamine E for long-term storage, detergent/stabilizer (2.0%) for the complete formation of oil/water emulsion, dimethicone (0.35%) for good skin care, and sorbitol for skin moisturizer were also added as ingredients. Physical or chemical degradation of formulated products stored at $0^{\circ}C$, $25^{\circ}C$, or $40^{\circ}C$ was not observed for 60-day testing period. In clinical test, 68% of applicants observed wrinkle decrease after 8-week treatment. This result indicates that newly formulated cosmetics have strong potential for improving wrinkle skin care.

Retinoids in anti-wrinkle cosmetics are widely used for the treatment of the photoaging skin these days, but very unstable in the presence of water. Multilamellar liquid crystal vesicles consisted of $poly(oxyethylene)_{15}oleyl$ ether $(POE_{15}OE)$ or $poly(oxyethylene)_{15}stearyl$ ether $(POE_{15}SE)$, cetostearyl alcohol (CSA) and cholesterol or oils were prepared to increase the stability of retinyl acetate or retinyl palmitate. $POE_{15}SE-CSA-Water$ systems were more unstable than $POE_{15}SE-CSA-Water$ systems due to the bended structure of oleyl groups. For the modification of vesicles, cholesterol was added. The enthalpy values were decreased reaching to zero and the water permeability of systems was decreased, but the stabilizaton of retinyl acetate was not greatly improved. The stability of retinyl acetate may depend on its location in the structure. Various oils were added for further stabilization and isopropyl myristate was most effective. In practice, retinyl palmitate showed better stability in the same vesicle than retinyl acetate, and the improved vesicles could be used for the anti-wrinkle cosmetics

Phytoestrogens derived from plants and foods, which are diphenolic compounds with structural similarities to natural and synthetic estrogens, have been shown to estrogenic and antiestrogenic actions. Particularly, recent study revealed that phenolic compounds in safflower seed, such as serotonin derivatives, lignans and flavonoids, could be acted as phytoestrogens. Safflower (Carthamus tinctorius L.) seed extract (SID C.SE), therefore, are receiving a renewed interest as potential therapeutic source against skin wrinkles induced by estrogen deficiency. This study was conducted to investigate the anti-wrinkle effect of SID C.SE on normal human fibroblasts through the expression of type I procollagen and UVA-induced MMP-1 in vitro. The SID C.SE increased the type I procollagen expression, comparable to trans-retinol and reduced UVA-induced MMP-1 expression in a dose-dependent manner. The clinical study indicated that cream group treated with $0.1\%$ SID C.SE significantly reduced a skin wrinkles, as compared with a control (non-treated cream group) (p<0.05). These results suggest that the safflower seed extract may be useful as potential source of anti-wrinkle cosmetics.
