It has been reported that certain ingredients added to cosmetics clog the skin pores and this can cause outbreaks of comedones which are the primary sign of acne leading to inflammatory acne. This research aims to establish objective evaluation criteria for non-comedogenic cosmetics suitable for acne prone skin. The research has been carried out to examine non-comedogenic test performed in foreign clinical institutions and to establish the evaluation method for detecting comedones outbreaks through repetitive closed back-patch test, Also, usability evaluation on face skin is performed additionally to the same subjects. The analysis of the comedones collected through repetitive closed back-patch test confirmed that the test products, moisturizer and sunscreen product, did not cause comedones. These results had no correlation with the analysis result of the comedones collected from face skin or visual evaluation of acne by Global Acne Grading System (GAGS) in face usability test. Additionally, Oil red O staining was performed on the collected comedones specimen for easy distinction of comedones from hair follicle in image analysis. The analysis result of stained specimen showed higher precision than that of non-stained specimen. This study established a new version of non-comedogenic test for cosmetics, whose objectivity and reliability were improved by inclusion of comedones staining step.

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.

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.

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.
