    Skin Therapy Lett 2016 Jan;21(1):1-7
    Spalding Drive Plastic Surgery and Cosmetic Dermatology, Beverly Hills, CA, USA.
    Dyschromia is a leading cause for cosmetic consultation, especially in those with diverse skin types (mixture of ethnicities) and with the rise of non-core and untrained physicians performing cosmetic procedures. Melasma and post-inflammatory hyperpigmentation (PIH) account for the majority of cases and are characterized by pigmented macules and patches distributed symmetrically in sun-exposed areas of the forehead, cheeks, and chin in melasma, and irregularly in areas of inflammation or an inciting traumatic event with PIH. Treatment is challenging and focused on a variety of mechanisms to stop, hinder, and/or prevent steps in the pigment production (melanocytic hyperactivity) process, breaking down deposited pigment for internal removal or external release, exfoliating cells to enhance turnover, and decreasing inflammation.

    What's new in acne? An analysis of systematic reviews and clinically significant trials published in 2010-11.
    Clin Exp Dermatol 2011 Dec;36(8):840-3; quiz 843-4
    Centre of Evidence Based Dermatology, University of Nottingham, Nottingham, UK.
    This review summarizes important clinical developments in acne treatment identified in five systematic reviews and two significant primary research studies, published between March 2010 and February 2011. Although evidence showing a direct link between development of bacterial resistance and oral antibiotic therapy for acne is not convincing, prescribers can still tailor their practice to minimize future risks by stopping treatment when appropriate, using benzoyl peroxide, and avoiding combining topical and systemic antimicrobials. A systematic review evaluating combination products containing benzoyl peroxide did not show convincing evidence that such products are superior to monotherapies. Read More

    Complementary antioxidant function of caffeine and green tea polyphenols in normal human skin fibroblasts.
    J Drugs Dermatol 2011 Jul;10(7):753-61
    SUNY Downstate Medical Center, Department of Dermatology, Brooklyn, NY 11203, USA.
    The study of free radicals is particularly relevant in the context of human skin carcinogenesis and photoaging because of these oxidants' ability to induce DNA mutations and produce lipid peroxidation byproducts, including 4-hydroxy-2-nonenal (HNE).
