Acne vulgaris is a highly prevalent skin disorder characterized by hyperseborrhea, inflammation, and Propionibacterium acnes overgrowth. Only isotretinoin and hormonal therapy reduce sebum production. To identify a new drug candidate that modulates sebum, we examined the effects of EGCG, the major polyphenol in green tea, on human SEB-1 sebocytes and in patients with acne. In SEB-1 sebocytes, we found that EGCG reduced sebum by modulating the AMPK-SREBP-1 signaling pathway. EGCG also reduces inflammation by suppressing the NF-κB and AP-1 pathways. EGCG also induces cytotoxicity of SEB-1 sebocytes via apoptosis and decreases the viability of P. acnes, thus targeting almost all the pathogenic features of acne. Finally, and most importantly, EGCG significantly improved acne in an 8-week randomized, split-face, clinical trial, and was well tolerated. Our data provide a therapeutic rationale for the use of EGCG in acne.Journal of Investigative Dermatology advance online publication, 25 October 2012; doi:10.1038/jid.2012.292.

    ABSTRACT: Background Blue and red light have been reported to have beneficial effects on acne. However, there has been no double-blind, randomized study of acne treatment for combined blue and red light-emitting diode (LED) devices, and the associated molecular mechanisms have rarely been investigated. Objectives To evaluate the efficacy, safety and histological changes of combined blue and red LED phototherapy for acne vulgaris. Methods Thirty-five patients with mild-to-moderate acne were randomly assigned to either a home-use irradiation group using an LED device, or a control group using a sham device. The treatment group was instructed to serially irradiate their forehead and cheeks with 420-nm blue light and 660-nm red light for 2·5 min twice daily for 4 weeks. Results At the final visit at 12 weeks, both inflammatory and noninflammatory acne lesions had decreased significantly, by 77% and 54%, respectively, in the treatment group. No significant difference was observed in the control group. In the treatment group, sebum output reduction, attenuated inflammatory cell infiltrations and a decreased size of the sebaceous gland were found. The immunostaining intensities for interleukin (IL)-8, IL-1α, matrix metalloproteinase-9, toll-like receptor-2, nuclear factor-κB, insulin-like growth factor-1 receptor and sterol response element binding protein (SREBP)-1 were reduced concomitantly. Messenger RNA expression of SREBP-1c was also decreased. No severe adverse reactions were reported. Conclusions This LED phototherapy was safe and effective for treating not only inflammatory but also noninflammatory acne lesions, with good compliance. The experimental results correlated well with clinical results, partly elucidating the related molecular mechanisms.

    ABSTRACT: In recent years, significant progress has been made in the understanding of the pathophysiological mechanisms of acne and the role of Propionibacterium acnes. With this review, the authors aim to provide an update on the current understanding of the role of P. acnes in the development of acne lesions and analysing the potential implications for future treatments. A total of 188 articles published between January 1980 and March 2013 were searched using key words such as acne, P. acnes, microbiology, Corynebacterium acnes, acne vulgaris, pathogenesis, antibiotic, vaccination and a combination of those key words. From those articles, 77 were analysed in depth. Recent data confirm that P. acnes has a strong proinflammatory activity and targets molecules involved in the innate cutaneous immunity, keratinocytes and sebaceous glands of the pilosebaceous follicle and leads to the development of comedones. Furthermore, the profile of its different strains may differ between healthy subjects and acne patients. The better understanding of the role of P. acnes may allow for new perspectives in the treatment of acne. Novel therapies should target molecules implicated in the activation of innate immunity, including toll-like receptors, protease-activated receptors and topical antimicrobial peptides; the latter may be an alternative to topical antibiotics and thus a solution for limiting bacterial resistance induced by topical macrolides. Vaccines may also be promising. However, the most appropriate candidate remains to be selected.

    ABSTRACT: The skin of most mammals is characterised by the presence of sebaceous glands (SGs), whose predominant constituent cell population is sebocytes, that is, lipid-producing epithelial cells, which develop from the hair follicle. Besides holocrine sebum production (which contributes 90% of skin surface lipids), multiple additional SG functions have emerged. These range from antimicrobial peptide production and immunomodulation, via lipid and hormone synthesis/metabolism, to the provision of an epithelial progenitor cell reservoir. Therefore, in addition to its involvement in common skin diseases (e.g. acne vulgaris), the unfolding diversity of SG functions, both in skin health and disease, has raised interest in this integral component of the pilosebaceous unit. This practical guide provides an introduction to SG biology and to relevant SG histochemical and immunohistochemical techniques, with emphasis placed on in situ evaluation methods that can be easily employed. We propose a range of simple, established markers, which are particularly instructive when addressing specific SG research questions in the two most commonly investigated species in SG research, humans and mice. To facilitate the development of reproducible analysis techniques for the in situ evaluation of SGs, this methods review concludes by suggesting quantitative (immuno-)histomorphometric methods for standardised SG evaluation.
