The skin condition varies by the parts of the face. This study intended to visualize the facial skin based on the characteristics including moisture, sebum, dryness, amount of dead skin cells, and roughness by sectionalizing the facial skin into 9 areas. A total of 98 female in their 20~35s were selected, and the characteristics of skin by area were selected and listed in the order, and the area they felt each characteristic most strongly was analyzed with a weight and the result was visualized. The result showed that the area where they felt dryness the most was around the lips and eyes, and the area where the largest amount of dead skin cells and rough skin existed was the chin. There was a significant increase in moisture content (p <.05), and 90.5% of satisfaction with dryness was satisfied. The result of this study will be used as a basic data for the development of a cosmetic mask pack or a functional cosmetic product for each part.

In this study, a formula (EJ-F101) was prepared to develop a raw material for acne-prone skin improvement using wheat germ extract, and a clinical trial cream was prepared and clinical trials were conducted. As a result of the analysis, when comparing before and after using the product, both the test group and the control group showed significant improvement effects in terms of open comedones, occluded comedones, papules, sebum and oil content in the facial region at 4 weeks after product use, compared to the control group in the test group which showed a more significant improvement effect. As a result of the survey on the efficacy of the product, most items showed higher positive answers in the test product compared to the control product four weeks after the use of the product, and about 43-81% of the study subjects answered positively in the test product, except for the "open surface" item. In addition, for all items related to the usability of the product, about 14-86% of the test group and 38-90% of the control group answered positively at the time point 4 weeks after using the product. As a result of skin safety evaluation, no adverse skin reactions were observed in all subjects of this study. Based on the above results, it is considered that the cream using wheat germ extract is suitable for use on acne-prone skin(non comedogenicity).

Wrinkle formation is mainly attributed to the environmental factors such as UV rays, air pollution, smoking and stress etc. Especially, UV rays induce premature skin aging which is characterized by deep wrinkle, leathery dryness etc. Recently, researches on the wrinkle formation and its prevention have been the main theme in cosmetics fields. We have studied the various plant extracts having anti-wrinkle effects and finally showed that Noni (Morinda citrifolia) extracts have the efficacy of promoting the type I collagen synthesis in normal human fibroblast, using PICP assay. We purified one active compound from Noni extracts and identified its structure. It was identified as 6,7-Dimethoxy-2H-1-Benzopyran-2-one; scopoletin by $^1H-NMR,\;^{13}C-NMR,$ IR, Mass analysis. Scopoletin increased collagen synthesis in a dose dependent manner (89.5% at $0.2{\mu}g/mL$). In order to verify the anti-aging effectiveness of the cream containing 3% noni extracsts, we performed the in vivo test with some female volunteers for 12 weeks. It reduced the signs of aging, especially face wrinkles. From these results, we conclude that the noni extracts could be used as an useful anti-wrinkle agent.

Scleroderma is a connective tissue disease of unknown etiology, but known as a kind of auto-immune disease. It is most common in women especially in $30{\sim}50$ years, and very rare in childhood. It can be classified into two main classes : localized scleroderma & systemic sclerosis. Localized type has better prognosis, and usually involves skin only, or in some cases, the muscle below, except inner organs. Systemic type involves skin, oral mucosa and major internal organs. Involving facial skin, we can see small and sharp nose, expressionless stare and narrow oral aperture. Usually they have Raynaud's phenomenon, and in progress, show mouth opening limitation and sclerosis of tongue and gingiva. It is called CREST syndrome showing calcinosis cutis, Raynaud's phenomenon, esophageal dysfunction, sclerodactyly, and telangioectasia. Treatment of scleroderma is systemic and localized steroid therapy, use of collagen-link inhibitor (D-penicillamine), immune depressor and etc. Mouth opening limitation can be improved by mouth stretching exercise. We report a 6 years old boy, diagnosed with localized scleroderma who had mouth opening limitation. We could get additional mouth opening, and have done successful restorative treatment of mandibular and maxillary 1st and 2nd deciduous molar under deep sedation with nitrous oxide and enflurane.

We herein describe a feline case of facial dermatitis whose histopathological features resembled to those of FHV-associated ulcerative dermatitis. A 3-year-old, intact male domestic short-haired cat was presented with 2-years history of pruritic dermatitis that initially appeared on periocular area and extended toward the entire face. The cat had ocular discharge and conjunctivitis from 2-month of age. Clinically, skin lesions were characterized as erythema, erosions and ulcers covered with crusts on the facial and perianal area. Histopathologically, the facial lesion was characterized as interface dermatitis with hydropic degeneration at the basal layer, and single cell necrosis of keratinocytes. In addition, the epidermal and dermal necrosis infiltrated with eosinophils, and intranuclear inclusion bodies in keratinocytes were also recognized. Moreover, feline herpesvirus-1 gene was detected by a PCR analysis using a swab obtained from the crusted lesions. Based upon these findings, the present case was considered as having FHV-associated ulcerative dermatitis. Therapy including oral acyclovir and topical recombinant feline interferon omega resulted in marked improvement of the skin and mucosal lesions.
