Purpose: The aim of this study was to systematically screen the literature for studies reporting cosmetic material in the oral and maxillofacial complex to shed light on the types of cosmetic materials, their radiographic appearance, and possible complications. Materials and Methods: Five electronic databases were reviewed for eligible studies. The general search terms were "cosmetic," "filler," "face," and "radiograph." Demographics, material types, clinical and radiographic presentation, and complications were recorded. Results: Thirty-one studies with 53 cases met the inclusion criteria. The mean age was 52.6±15.4 years with a 4 : 3 female-to-male ratio. The most common material was calcium hydroxyapatite (CaHa) (n=14, 26.4%), found incidentally. The materials were generally located within the upper cheek and zygoma (n=35, 66.0%), radiographically well-defined (n=44, 83%), and had no effects on the surrounding structures (n=27, 50.9%). The internal structure was radiopaque (calcification, hyperdensity) for gold wires, CaHa, bone implants, and secondary calcification or ossification. Outdated cosmetic materials or non-conservative techniques were infiltrative, had effects on the surrounding structures, and presented with clinical signs, symptoms, or complications. Conclusion: Conventional radiography, cone-beam computed tomography, and multi-detector computed tomography are useful to differentiate several cosmetic materials. Their magnetic resonance imaging appearance was highly variable. The infrequent inclusion of cosmetic materials in the differential diagnosis implies that medical and dental specialists may be unfamiliar with the radiographic appearance of these materials in the face.

The in Vitro chemosensitivity of fibroblast cell strains was determined using a semiautomated tetrazolium-based colorimetric assay(MTT assay) to 16 cosmetic materials. This assay is useful method to evaluate toxic effects of the chemicals. From assay results, we determined that the preservatives are more toxic than moisteurizers. The chemicals in the same group have a different toxicity. That is, in preservatives, Germall -115 is more toxic than Danisol -M, -p, and in surfactant sodium laurel sulfate than Myrj 52, and in moisteurizers, 1, 3-butylene glycol is more safe than the others. When the results from this assay for preservatives were compared with patch test results, good correlation was observed. Forthemore, this assay method can be used together with Patch test for the evaluation of the chemical toxicity, particularly in cosmetic field.

This work reported the trends of bioceramic materials for beauty-care applications with the several represent examples - tone-up, sun-care and anti-pollution cosmetics. The development of cosmetic techniques was discussed and reviewed with various ceramic hybrid materials. Moreover, we also reported the preparation and application of functional cosmetics with silicified liposome particles as a good make-up material for controlled release with natural compounds. The homogeneous loading and highly controlled-release formulation with porous and silicified ceramic liposome ceramic materials were discussed.

Animal testing was used traditionally in the cosmetics industry to confirm product safety, but has begun to be banned; alternative methods to replace animal experiments are either in development, or are being validated, worldwide. Research data related to test substances are critical for developing novel alternative tests. Moreover, safety information on cosmetic materials has neither been collected in a database nor shared among researchers. Therefore, it is imperative to build and share a database of safety information on toxicological mechanisms and pathways collected through in vivo, in vitro, and in silico methods. We developed the CAMSEC database (named after the research team; the Consortium of Alternative Methods for Safety Evaluation of Cosmetics) to fulfill this purpose. On the same website, our aim is to provide updates on current alternative research methods in Korea. The database will not be used directly to conduct safety evaluations, but researchers or regulatory individuals can use it to facilitate their work in formulating safety evaluations for cosmetic materials. We hope this database will help establish new alternative research methods to conduct efficient safety evaluations of cosmetic materials.

Packaging has been regarded as a environmental problem because of its relatively high portion of municipal solid wastes. Especially, cosmetic packaging has been focused because of characteristics of cosmetic packaging. Cosmetic products are highly sensitive products that pursue the beauty differently from other products. Cosmetic packaging materials are difficult to be recycled. Purpose of this study is to suggest the method to improve the environmental friendly packaging of cosmetic products. This study contains the major governmental policies on the cosmetic packaging in terms of environment issues in Korea, and suggested methods to develop the environmental friendly packaging of cosmetic products.

최근 생활수준의 향상과 더불어 자연친화적인 제품을 사용하고자 하는 웰빙소비성향이 두드러지며 천연소재를 이용한 각종 생활용품이나 화장품의 개발도 매우 활발하게 진행되고 있다. 특히 민간에서 오랫동안 약재로 사용해 오던 식물들의 생리활성들이 피부과학적으로 입증되면서 그 식물들로부터 유효성분을 농축하거나 분리하여 화장품 등에 이용하고 있다. 또한 기능성 화장품(functional cosmetics)의 출현으로 소비자들의 인식도 높아져 피부의 생리활성을 향상시켜주는 천연원료를 첨가하여 미백(whitening), 주름개선(wrinkle improvement) 등의 효과를 나타내는 제품들도 많이 개발되어 왔다. 본고에서는 그 동안 연구되어져 온 천연물을 기능별로 분류하여 간략히 설명하고 화장품 천연원료로 개발된 fructan, Areca extract, Portulaca extract, Licorice extract, Dandelion extract, Ulmus extract, SC-glucan, Arbutin, Sophora extract 등의 피부 생리환성 등을 소개하고자 한다.

MMA-5와 Malva는 각각 해조류와 일년 또는 다년생 풀에서 추출되었으며 이들은 과거부터 보습, 수렴, 단백질 합성 등의 효과를 가지는 것으로 구전되어왔다. 상처치유에 대한 이들의 효과를 조사하기 위해서 우리는 배양된 사람이 표피 세포를 이용하여 세포증식, 세포부착, 그리고 세포이동에 미치는 영향을 조사하였고 실험결과 MmA-5와 Malva추출물들은 상처치유에 유효한 효과를 나타낼 수 있음을 밝혀냈다.
