화장품에 배합되는 원료 중에 피부 모공을 막아 여드름의 초기단계인 면포를 유발함으로써 염증성 여드름으로 악화시키는 사례가 보고되고 있다. 본 연구는 '여드름 피부에 사용이 적합한' 면포 비유발성 화장품의 객관적인 평가 기준을 마련하고자 하였다. 외국 임상기관에서 실시하고 있는 non-comedogenic test를 조사하고 등 상부 반복 폐쇄 첩포를 통해 면포 유발 평가방법을 확립하고자 연구를 수행하였다. 또한 안면부 사용성 시험을 동일 피험자에게 추가로 진행하였다. 등 상부 반복 폐쇄 첩포를 통해 면포를 채취하여 분석한 결과 시험시료로 사용한 보습제와 자외선 차단제가 면포를 유발하지 않음을 확인할 수 있었고, 동일한 시험제품을 안면부에 사용하여 얻은 면포 유발 결과와 Global acne grading system (GAGS)의 여드름 육안평가 결과는 상관관계가 없었다. 또한 사진 판독을 통해 분석하는 면포와 모낭의 구별을 용이하게 하기 위해 면포 채취 표본에 Oil red O staining을 실시하였다. 염색을 한 경우의 표본이 염색을 하지 않은 표본과 비교하여 결과 간 높은 일치도를 확인하였다. 본 연구에서는 Oil red O staining을 통해 객관성과 신뢰성을 증진시킨 새로운 버전의 화장품 면포 비유발성 평가법을 확립하였다.

Acne is a relatively common disorder, especially in the adolescent or 20-30th young people. The condition is characterized by comedones, papules and pustules. Acne has social and psychological influence on the acne patients. But there is no perfect treatment of acne. It is known that Herba Houttuyniae has anti-inflammatory action and anti-bacterial action. Therefore, we studied the effect of 5% Herba Houttuyniae extract solution on the acne. The study was designed to compare the efficacy of 5% Herba Houttuyniae solution on the acne. The study was carried out on two groups-a experimental and a control group- for 4 weeks. Efficacy was determined by investigating counts of non-inflammatory open and closed comedones, and inflammatory papules and pustules once a week. After a experiment self-assessment was checked. As the result of the study, we found that a significant difference was observed in the mean counts and self-assessment of the experimental group. So we concluded that Herba Houttuyniae has a clinical effect on the acne.

Tests of stability and toxicity, and clinical evaluation of anti-acne activity suggest that cryptotanshinone, a constituent of the roots of Salvia miltiorrhiza Bunge, is an effective active ingredient for acne vulgaris treatments. Acne vulgaris, called acne or pimples, is the most common disease of the pilosebaceous follicle unit of the skin. It affects nearly 80% of people between the ages of 11 and 30. Approximately 30% of teenagers have acne of sufficient severity to require medical treatment. Acne is a follicular disorder of the skin. It occurs in specialized pilosebaceous units on the face and body. Acne develops when these specialized follicles undergo pathologic alterations that result in the formation of non-inflammatory lesions (comedones) and inflammatory lesions (papules, pustules and nodules). An abnormality of keratinizing epithelium of these follicles, thought to be due to the action of sebum synthesized and secreted by the androgen-sensitive sebaceous glands, leads to inflammation induced by the follicular bacterium Propionibacterium acnes. Therapy involves treatments that modify these pathogenic factors and includes drugs with antikeratinizing, antibacterial and antiseborrheic actions. Acne vulgaris is a very frequent disease, seen primarily in adolescents, involving the sebaceous follicles. Acne vulgaris is characterized by a great variety of clinical inflammatory and non-inflammatory lesions: comedones, papules, pustules, nodules, cysts and scars. Acne vulgaris is a multi-factorial disease. Although its pathogenicity is unclear, extensive studies have shown that hyperseborrhea, superinfection by P. acnes and endocrinologic androgenic changes play a role in the development of acne vulgaris.

Objective : This study is to investigate the effect of Bojoongikki-tang on Acne patients Methods : We treated 3 acne patients diagnosed as the deficiency of Qi with Bojoongikki-tang(Buzhongyiqitang), comedon extraction by needle and stamp acupunctures. After treatments we compared the before and after photos, and estimated by Korean Acne Grading System(KAGS1-4). Results & Conclusions : After taking Bojoongikki-tang(Buzhongyiqi-tang) and extruding comedones by needle, the acne was improved. After stamp acupuncture, the acne scar was improved. This study shows that the acne can possibly be diagnosed as the deficiency of Qi. So further studies are needed continuously.

The intradermal injection of Propionibacterium acnes (ATCC 6919) into the ears of female Sprague-Dawley rats produced a chronic inflammation with the formation of acneiform lesions. Inflammation was characterized by more than four times of ear thickness and 2.8 times of ear weight at day 21. Histologically, massive infiltration of neutrophils, macrophage and lymphocytes, hyperplastic epidermis, comedones containing keratin mass and inflammatory materials were observed. Both ginseng saponin and extract from Korean red ginseng significantly redliced the ear thickness and their effects were similar to that of benzoyl peroxide. Ginseng samples and beneoyl peroxide modified lipid constituents of P. acnesinjected rat ear tissues. Even though no marked histological changes in inflammatory lesions were observed in ginseng-treated ear tissues, Korean red ginseng showed a possibility of reduce in the risk of acne development.

Objective : This study is to investigate the effect of Yukmijihwangtang Gamibang on Male Acne patients. Methods : We treated 3 male acne patients diagnosed as the deficiency of Yin with Yukmijihwangtang Gamibang and comedon extraction. After treatments We compared the before and after photos, and estimated by Korean Acne Grading System(KAGS). Results & Conclusions : After taking Yukmijihwangtang Gamibang, extruding comedones by needle and appling acupuncture, the acne was improved. This study shows that the acne can possibly be diagnosed as the deficiency of Yin. So further studies are needed continuously.

Acne, which intrucdes the pilosebaceous unit, is a chronic inflammatory disease. The symptom of comedones, papules, pustules, cysts, nodules and scar mainly raises on the face, upper back, shoulder and neck. The cause of acne is the secreting growth of sebum, abnormal follicular keratiniziation, the form of group of propionibacterium acnes, and the respones of inflammation etc. But the original mechanism of the cytobiologic level is exactly not known yet. We treated three patients suffered from acne with acupuncture, venesection, Chungsangbangpung-tang, wet dressing with Gamihwangryunhaedok-tang. After treatments we observed the improvement. Based on this study, it is considered that acupuncture, venesection, Chungsangbangpung-tang wet drssing with Gamihwangryunhaedok-tang can be applied to the management of acne.

Chungsangbangpungtang is one of the most frequently used medical treatments for the acne. A study on 25 patients with acne who took Chungsangbangpungtang shows that the oral medication of Chungsangbangpungtang is the best efficient remedy for a person who has acne less than one year without nodules.

Acne vulgaris is a common inflammatory skin disease of the pilose-baceous unit. It appears as lesions consisting of comedones, papules, pustules, and nodules of varying shapes and severity. In general, the first-line treatment for acne vulgaris includes topical and oral medication. Recently, various physical modalities have also been investigated. The use of laser therapy is steadily increasing because of its fewer side effects, short procedure time, and rapid results. In particular, laser therapy assisted with carbon suspension application is effective for acne vulgaris but may sometimes result in discomfort due to odor and dust formation during the procedure. Herein, we report that acne vulgaris and enlarged facial pores can be safely and effectively treated with laser therapy assisted with diamond particle suspension and gold microparticle application, which can address the discomfort caused by the carbon suspension application.

본 연구는 밀배아 추출물을 이용하여 여드름성 피부 개선용 원료를 개발하고자 포뮬라 (EJ-F101)를 제작하여 이를 이용하여 임상시험용 크림을 제조하였으며 임상실험 진행하였다. 분석 결과, 제품 사용 전·후 비교 시제품 사용 4주 후 시점에서 시험군과 대조군 모두 안면 부위의 병변 개방면포, 폐쇄면포 구진 피지 및 유분량 항목에 대해 유의한 개선 효과를 보였고, 대조군에 비해 시험군에서 좀 더 유의한 개선 효과를 보였다. 제품의 효능에 대한 설문 결과, 대부분 항목에서 제품 사용 4주 후 시점에서 대조 제품에 비해 시험제품에서 긍정적인 답변이 높게 나타났으며, '개방 면포' 항목을 제외하고 시험제품은 약 43~81%의 연구대상자가 긍정적으로 답변하였다. 또한, 제품의 사용성에 관한 모든 항목에 대해 제품 사용 4주 후 시점에서 시험군은 약 14~86%, 대조군은 약 38~90%의 연구 대상자가 긍정적으로 답변하였다. 피부 안전성 평가 결과, 본 모든 연구대상자에게서 피부 이상반응은 관찰되지 않았다. 위와 같은 결과를 근거로 밀배아 추출물을 이용한 크림은 여드름성 피부에 사용하기 적합(non comedogenicity) 한 것으로 사료된다.
