Objectives: Although Acne vulgaris is a chronic skin disease, which its standard treatment causes therapeutic limitations and some common adverse effects, medicinal plants can be effective in treatment with low adverse effects as combination therapy. Myrtle (Myrtus Communis) has some beneficial properties, which has been administered topically and orally for some skin diseases in Persian medicine. This study aimed to compare the efficacy and safety of Myrtle formula and 1% clindamycin topical solution. Methods: This was a split-face clinical trial that was done on 55 patients with mild to moderate acne vulgaris for 16 weeks. The patients received topical Myrtle solution to the right side of the face (group 1) and clindamycin solution to the left side (group 2) twice daily for 12 weeks. All participants were examined for the acne severity index (ASI) and total acne lesions counting (TLC) at certain times during the study. Then, they stopped using them for four weeks. They also did not take the drug in the final four weeks of the study. Results: Forty-eight patients completed the study for 16 weeks; 40 (83.2%) patients were female and the rest of them were male. The mean age and standard deviation were 25.62 ± 7.62 years. After 12 weeks, the percentage changes of comedones, inflammatory lesions, ASI and TLC were significantly reduced in both groups (p < 0.001). The percentage change of inflammatory lesions and ASI decrease was significantly higher in the group 1 (p = 0.03). There was no significant difference in the incidence of side effects between the two groups. There was a more significant decrease in sebum percentage change in the group 1 (p = 0.003). Conclusion: Myrtle lotion was effective and safe for the treatment of mild to moderate acne vulgaris.

Acne, also known as Acne vulgaris, is a common disorder of human skin involving the sebaceous gland and Propionibacterium acnes (P. acnes). The purpose of this study was to demonstrate whether anti-acne herbal complex (AAHC), a functional extract from herbal complex can be used for acne treatment as a natural product. We first demonstrated anti-acne activity of AAHC in mouse acne model. Acne was induced by injecting P. acnes on the backside $2{\times}10^7$ CFUs in ICR mice and then the mice were treated with AAHC by dermal application once daily. ACFREE$^{(R)}$ (clindamicin phosphate) was used as a positive control. Treatment with AAHC decreased the P. acnes-induced skin swelling and inflammation. AAHC treatment significantly decreased serum DHT concentration in acne-induced mice. Especially, treatment of 20% AACH in mice was more effected than 40%. We next evaluated the antimicrobial property of AAHC against P. acnes, Staphylcococcus aureus (S.aureus), and Escherichia coli (E. coli). Incubation of P. acnes, S. aureus, and E. coli with AAHC showed minimal inhibitory concentration (MIC) values against the bacterial growth lower. Alamar blue method was also carried for the antibacterial activity. It was effectively MIC level at 6.25% of P. acnes. AAHC effectively inhibited the growth of S. aureus and E. coli at 0.097% on MIC level, respectively. Our results showed the potential of using AAHC as an alternative treatment for antibiotic therapy of acne and the application of AAHC as a herbal medicine for acne treatment.

Activation of the NLRP3 inflammasome is critical for host defense as well as the progression of inflammatory diseases through the production of the proinflammatory cytokine IL-1β, which is cleaved by active caspase-1. It has been reported that overactivation of the NLRP3 inflammasome contributes to the development and pathology of acne vulgaris. Therefore, inhibiting activation of the NLRP3 inflammasome may provide a new therapeutic strategy for acne vulgaris. In this study, we investigated whether auranofin, an anti-rheumatoid arthritis agent, inhibited NLRP3 inflammasome activation, thereby effectively treating acne vulgaris. Auranofin suppressed NLRP3 inflammasome activation induced by Propionibacterium acnes, reducing the production of IL-1β in primary mouse macrophages and human sebocytes. In a P. acnes-induced acne mouse model, injection of P. acnes into the ears of mice induced acne symptoms such as redness, swelling, and neutrophil infiltration. Topical application of auranofin (0.5 or 1%) to mouse ears significantly reduced the inflammatory symptoms of acne vulgaris induced by P. acnes injection. Topical application of auranofin led to the downregulation of the NLRP3 inflammasome activated by P. acnes in mouse ear skin. These results show that auranofin inhibits the NLRP3 inflammasome, the activation of which is associated with acne symptoms. The results further suggest that topical application of auranofin could be a new therapeutic strategy for treating acne vulgaris by targeting the NLRP3 inflammasome.

Objectives : The purpose of this study is to review clinical studies about the efficacy of fire needling for the treatment of acne vulgaris. Methods and Results : In this review, Oasis, NDSL, CNKI, PubMed, Cochrane, J STAGE and CINII were used as the main databases for searching for medical journals, using the keywords "acne and fire needling"," acne and fire needle"," acne and fire acupuncture", and" acne and red hot needle". The initial search range included only randomized controlled trials (RCTs), and papers not matching inclusion criteria were excluded. Initially a total of 108 studies were found, with ten being excluded during title and abstract screening. After scanning 98 papers, a total of 31 RCTs were selected and analyzed. In the 31 RCTs, patients with acne were randomized into groups for treatment and control. Specifically, the treatment group received fire needling, while the control group were concurrently given other treatments. The results of the completed studies have shown that the treatment group receiving fire needling demonstrated significant improvement compared to the control group. Conclusion : During our study, it was verified that the efficacy of fire needling for the treatment of acne vulgaris was both significant and meaningful. Therefore, fire needling can be a safe and effective alternative treatment for acne. However, to confirm this result, further investigation in a traditional clinic is required, accompanied by high quality studies including randomized, placebo-controlled double-blind trials.

Acne vulgaris is a very common condition affecting up of about 80% to 90% of adolescents. The patients with acne have been shown to be adversely impacted by the effect of acne on their quality of life. Four factors are believed to play a key role in the development of acne lesions: excess sebum production, disturbed keratinization within the follicle, colonization of the pilosebaceous duct by Propionibacterium acnes, and the release of inflammatory mediators into the skin. Consequently, the target for acne therapy is these well-known pathogenic factors responsible for this disease state. Topical retinoids correct abnormal keratinization, but it should be applied cautiously because of irritation. Benzoyl peroxide is an effective bactericidal agent against P. acnes. Main topical antibiotics are erythromycin and clindamycin. Fixed combination topical products with retinoids, benzoyl peroxide and antibiotics have been introduced. Use of systemic antibiotics, including tetracyclines and macrolides rapidly improves inflammatory acne lesions. Oral isotretinoin is effective against all of the main pathogenic features of acne but is contraindicated in pregnant women and has been associated with cheilitis and dry skin. Hormonal therapy has been found to improve acne in some selective patients and should be considered for appropriate candidates. This review will present the general aspects of the pharmacological treatments for acne.

The study was aimed at developing an alternative therapeutic agent against acne vulgaris, one of the most common skin diseases, to meet the continuing demand for new therapies. Acne vulgaris is often associated with the acne-causing bacteria such as Cutibacterium acnes. To investigate the safety of agents against acne vulgaris, we evaluated the potential antibacterial activities of edible seaweeds against C. acnes in Korea. Forty-one edible seaweeds, including the brown, green, and red varieties, were selected for the antibacterial test. In comparison with other seaweeds, 70% ethanolic extracts of brown seaweeds, such as Cladophora wrightiana var. minor, Eisenia bicyclis, Ecklonia cava, Ishige foliacea, Ishige okamurae, Sargassum filicinum, and Sargassum miyabei Yendo, exhibited potential antibacterial activity against C. acnes with minimum inhibitory concentrations ranging between 64 and 128 ㎍/mL. To investigate the active anti-acne agents and to enhance our understanding of the antibacterial activities against C. acnes, further solvent-fractionation experiments are warranted. The findings imply that brown seaweeds can be a potential source of natural agents against acne vulgaris.

Post-acne erythema (PAE) is one of the major problems during or after treatment of acne vulgaris with any modality. A variety of therapeutic options have been described with various clinical outcomes and side effects. We report here on treating a patient with PAE using 595-nm picosecond-domain neodymium:yttrium-aluminum-garnet (Nd:YAG) laser. After four sessions of treatment, the patient displayed nearly complete improvement and no remarkable adverse effects. To the best of the authors' knowledge, this is the first case of the effective treatment of PAE using a 595-nm picosecond-domain Nd:YAG laser. We recommend that using a 595-nm picosecond-domain Nd:YAG laser can be both an effective and safe treatment option for treating PAE.

Propionibacterium acnes infection in skin tissue often causes acne vulgaris, commonly characterized by inflammatory papules, pustules, and nodules. Chitosan and its derivatives possess strong anti-inflammatory effects. In this study, the anti-inflammatory activity of chitosan-phytochemical conjugates on P. acnes-infected human skin keratinocytes (HaCaT) was evaluated. We designed a model of P. acnes-induced inflammation in viable HaCaT cells. Nitric oxide (NO), an inflammatory marker, was successfully elevated by P. acnes infection in HaCaT cells in a dose-dependent manner. Furthermore, the levels of NO were reduced by treatment with chitosan-phytochemical conjugates (chitosan-caffeic acid, -ferulic acid and -sinapic acid) in a dose-dependent manner. Among these conjugates, chitosan-caffeic acid exhibited the strongest NO suppression in HaCaT cells infected with P. acnes. The results obtained in this study suggest that chitosan-phytochemical conjugates could be used as a potential therapeutic agent against acne vulgaris.
