The forefoot reconstruction is a challenging field for plastic surgeons. Weight bearing tolerability and stability are important factor of choosing reconstruction methods, but cosmetic aspect has to be considered. 51 year old man visited our clinic with extensive degloving injury on right forefoot by roller. The soft tissue defect started from metatarsal area to the toe tip including nails. We harvested the anterolateral thigh flap and transferred it to the forefoot defect area with nerve coaptation. The flap was successful without skin necrosis or other complications. Secondary flap debulking surgery was performed after ten months from initial operation. Patient was satisfied with functional and cosmetic outcomes. The patient was able to wear shoes and walk with adequate sensory recovery. As there is few report about reconstruction of forefoot soft tissue defects, we report a unique case of the anterolateral thigh innervated free flap reconstruction in degloving injury.

In the aged skin especially in the face and eyelid, deep and slight wrinkles are one of the remarkable phenomena of aging and the cause of wrinkle is various. Among the cause of wrinkles an oxidative stress plays an important roles in wrinkle formation process. It caused the lipid peroxidation of cell membrane, the increase of the MMPs(MatrixMetalloProteinase) gene expression and cellular DNA damage. These ROS induced materials may cause the degradation of collagen matrix system in the dermis and cause the formation of skin wrinkle. So, it is very important for protecting skin wrinkle formation to regulate ROS activity. In this study, we developed one active ingredient having multi functional activities such as activation of collagen synthesis, inhibition of MMPs activity, lipid peroxidation and free radical scavenging activity and inhibition of free radical induced DNA damage in vitro. Pericarpium castaneae extracts showed collagen synthesis increase in Normal Human Fibroblast and the inhibition of elastase activity (IC$\_$50/ of Elastase: 43.9$\mu\textrm{g}$/㎖). It showed also anti-oxidative activity (IC$\_$50/ : 48$\mu\textrm{g}$/㎖) and free radical scavenging activity(IC$\_$50/: 7.6$\mu\textrm{g}$/㎖). Conclusively, Pericarpium castaneae extracts may be used as an ingredient for new anti-wrinkle cosmetics.

This study was carried out to investigate the melanin synthesis inhibitory effect of Aspergillus fumigatus fermented extract. In this study, we revealed the effects of A. fumigatus fermented extract on melanin contents, mushroom tyrosinase activity, and expression levels of mRNA and proteins of melanogenesis-related gene in B16F10 melanoma cells. A. fumigatus fermented extract inhibited both melanin contents and tyrosinase activity. In addition, the expression level of mRNA or proteins of melanogenesis was down-regulated in the A. fumigatus fermented extract treated B16F10 cells with dose-dependent manner. Moreover, when the clinical test was conducted, it was confirmed that the use of the fermented extract of A. fumigatus for 8 weeks improved skin brightness 1.586 times brighter and skin melanin 1.331 times better compared to the control product. Taken together, our results suggest that A. fumigatus fermented extract has melanogenesis inhibitory effect and whitening activity, thus it showed the possibility for using as a functional whitening cosmetic resource.

Human skin is continuously exposed to internal and external influences that may affect its condition and functioning. To maintain and improve skin condition, a wide variety of skin-care products is in the market. However, many of skin problems originate from internal causes, and the new insight into the relation between nutritional factors and skin is now receiving a great attention. Specific positive effects of nutrients or nutraceutical compounds on skin conditions may prove to be biologically relevant and may consequently allow for claims on products containing these compounds, resulting in the development of new functional food for optimal skin condition. In this review, these functions of nutrients and nutraceutical compounds in skin are summarized as providing a basis for the feasibility of the concept of functional foods for maintaining and improving skin condition.

This study was carried out to investigate the free amino acid and derivatives and phenolic acid and flavonoid compositions and contents of hot water and 95% ethanol extracts of Imperata cylindrica Beauvois var. koenigii root. The purpose of this study is to obtain basic data and to confirm their applicability as functional cosmetic and functional food ingredients on extracts. 15 kinds and 9 kinds of free amino acids were detected in both extracts, respectively. 5 kinds and 4 kinds of protein free-amino acid derivatives were detected in both extracts, respectively. Total phenol contents were 116.50 ± 0.06 and 140.10 ± 0.04 mg% in both extracts, respectively. The total flavonoid contents were 31.80 ± 0.03 and 43.90 ± 0.05 mg% in both extracts, respectively. 5 kinds and 6 kinds of phenolic acids were detected in both extracts, respectively. In the case of flavonoid analysis, no flavonoid compound was detected in the hot water extract while taxifolin was identified in the 95% ethanol extract. Based on the above results, the hot water and 95% ethanol extracts of I. cylindrica Beauvois var. koenigii root are rich in free amino acids, amino acid derivatives, phenolic acids and flavonoids which confirm their potential for applications in cosmeceuticals, nutricosmetics formulations and functional foods.

In this study, to explore the possibility of using discarded by-products of corn as a wrinkle-improving functional material, the active ingredient contained in each part including kernel, cob, husk, and silk of 10 varieties of chodang and waxy corn was identified and the content was analyzed to suggest the possibility of corn by-products as upcycling materials. As a result of evaluating the collagen synthesis efficacy of extracts by part, the cob in chodang and waxy corns showed significant activity at 100 ㎍/mL concentration of 176.5 and 140.0%, respectively. The LC-MS/MS qualitative analysis resulted in the identification of 18 components in the cob, of which N, N'-diferuloylputrescine (DFP) was selected as an active ingredient, and the quantitative analysis was conducted by variety and part. As a result, DFP was confirmed only in the cob and kernel, and it was most frequently detected in the cob of the Goldsugar of chodang corn (39.6 ㎍/g) and Daehakchal of waxy corn (38.4 ㎍/g). The cob is a by-product left over from grain removal, and is expected to create new added value as a material that promotes collagen synthesis. Through this study, we propose the possibility of using discarded cob as a wrinkle-improving functional material.

As fashion is a visual symbol that reflects age and culture, cosmetics and beauty are other products of fashion that move the time. A dominant designer of 20th century Chanel does not merely stand for a design innovation of fashion industry that created a vogue. With liberation from corsets that cruelly exaggerated and suppressed female body, meaning of style in modern fashion could be found not only in clothing but also in make-up and hair style. Simplest possible comfort was aimed for, and philosophical concepts of minimalism, modernism and dandyism were incorporated with clothing, cosmetics, perfume, make-up and hair style to establish aesthetical concept of total fashion. Chanel thought of cosmetics as an accessory with essential role and although her philosophy on cosmetics and beauty is not as well known as her clothing style, the authors believe that understanding such philosophy will become an important stepping stone for accurately understanding Chanel style. The purpose of this study is to firstly illuminate the idea that cosmetic beauty can be studied with artistic and philosophical background in addition to its functional side and to secondly investigate the reason why Chanel style is being loved by women with such durability over time and space and with what tempo fashion is connected with cosmetic beauty culture and develops. Third, by studying the ways in which characteristics of Chanel's fashion philosophy are expressed in cosmetics and beauty culture, this study aims to accurately understand Chanel's philosophy on cosmetics and beauty. The meaning of this study can be found by showing the evidence that globalization of Korean fashion beauty culture can be achieved only when cosmetics and beauty culture moves with an intimate connection to clothing culture.

In this study, a poly (amino acid)s derivative grafted with retinoic acids, which could form self-assemblies in an aqueous solution, was successfully synthesized. The synthesized amphiphilic poly (amino acid)s were controlled with 5, 10, 30 mol% substitution of retinoic acid. Then, the amphiphilic poly (amino acid)s were self-assembled by inter/intra molecular stacking of retinoic acids in an aqueous solution. Also, the increasing the degree of substitution (DS) of retinoic acids decreased the size of self-assembled nanoparticles and induced structural transition to bilayer structure from spherical structure. The retinol was stably encapsulated into a core of self-assembled nanoparticle with 10 mol% of DS. This strategy to prepare the self-assemblies of amphiphilic polyaspartamide will serve to improve the efficiency of targeted delivery for a functional cosmetic with various biological modalities.

Purpose: The authors applied Bilhaut-Cloquet procedure to Wassel type III and IV duplicated thumb, which was limited to patients with Wassel type I, II. This procedure was applied in order to improve the growth potential, range of joint motion, joint stability and cosmetic outcome. Methods: Sixteen patients received Bilhaut-Cloquet procedures to correct duplicated thumbs from May, 2005 to December, 2010. Seven patients were Wassel type III, nine patients were type IV. This procedure was applied not only to balanced type, but also unbalanced type or convergent type. Five patients were balanced type and eleven patients were unbalanced type. Convergent type of Wassel type IV was three. Sex ratio was the same, mean age at the operation was 20.1 months old (8~52 months old). Angular deformity, joint stability and range of joint motion and cosmetic outcome were considered together and estimated in Tada score. Also, postoperative subjective satisfaction score of the parents was evaluated by a 100-points scale. Results: Mean subjective satisfaction scored 75 points at 28 months after the operation. Radiologic study showed bony union of proximal phalangeal bone and stable joint in all patients. Range of motion was mean 20 degrees in interphalangeal joint and mean 73 degrees in metacarpophalangeal joint. Tada score showed 'good' in eleven patients (68.8%), 'fair' in three patients (18.7%) and 'poor' in two patients (12.5%). In seven patients those who were able to follow up for a long term showed no significant difference in length of proximal and distal phalangeal bones compared to the opposite thumb. Conclusion: Bilhaut-Cloquet procedure can be applied not only to balanced type of Wassel type III, IV duplicated thumb, but also to unbalanced type or convergent type that focused on functional reconstruction and cosmetic improvement.
