    Depigmentation Therapies for Vitiligo.
    Dermatol Clin 2017 Apr;35(2):219-227
    Vitiligo & Pigmentation Institute of Southern California, 5670 Wilshire Boulevard #650, Los Angeles, CA 90036, USA.
    The general goals of medical management of vitiligo are to repigment vitiliginous areas of skin and to stabilize the progression of depigmentation. However, for some patients with vitiligo affecting extensive body surface areas who are unresponsive to repigmentation therapies, depigmentation of the remaining normal skin may be a better choice. Candidates for depigmentation therapy should be carefully screened and patient education is essential. Read More

    Chemical-Induced Vitiligo.
    Dermatol Clin 2017 Apr;35(2):151-161
    Department of Dermatology, University of Massachusetts Medical School, 364 Plantation Street, LRB 225, Worcester, MA 01605, USA. Electronic address:
    Chemical-induced depigmentation of the skin has been recognized for more than 75 years, first as an occupational hazard but then extending to those using household commercial products as common as hair dyes. Since their discovery, these chemicals have been used therapeutically in patients with severe vitiligo to depigment their remaining skin and improve their appearance. Because chemical-induced depigmentation is clinically and histologically indistinguishable from nonchemically induced vitiligo, and because these chemicals appear to induce melanocyte autoimmunity, this phenomenon should be known as "chemical-induced vitiligo," rather than less accurate terms that have been previously used.

    Skin whitening agents: medicinal chemistry perspective of tyrosinase inhibitors.
    J Enzyme Inhib Med Chem 2017 Dec;32(1):403-425
    a PharmaCenter Bonn , Pharmaceutical Institute, Pharmaceutical Chemistry I, University of Bonn , Bonn , Germany.
    Melanogenesis is a process to synthesize melanin, which is a primary responsible for the pigmentation of human skin, eye and hair. Although numerous enzymatic catalyzed and chemical reactions are involved in melanogenesis process, the enzymes such as tyrosinase and tyrosinase-related protein-1 (TRP-1) and TRP-2 played a major role in melanin synthesis. Specifically, tyrosinase is a key enzyme, which catalyzes a rate-limiting step of the melanin synthesis, and the downregulation of tyrosinase is the most prominent approach for the development of melanogenesis inhibitors.

    Split-Face Comparison of an Advanced Non-Hydroquinone Lightening Solution to 4% Hydroquinone.
    J Drugs Dermatol 2016 Dec;15(12):1571-1577
    Introduction: Hyperpigmentation is a primary concern for many cosmetic patients because of its high rate of occurrence and significant impact on perceived age. While 4% hydroquinone has been the gold-standard of treatment, there is a growing interest in non-hydroquinone solutions, however, many of these newer solutions fail to deliver equivalent improvement.

    Methods: This double-blind, randomized, split-face study compares the effects of a new OTC non-hydroquinone lightening product (JM) to an available 4% hydroquinone lightening solution (OB) on the appearance of hyperpigmentation, texture, and ne lines and wrinkles. Read More

    Peroxisome proliferator-activated receptor α (PPARα) contributes to control of melanogenesis in B16 F10 melanoma cells.
    Arch Dermatol Res 2017 Apr 13;309(3):141-157. Epub 2017 Jan 13.
    Department of Biophysics, Faculty of Biochemistry, Biophysics and Biotechnology, Jagiellonian University, ul. Gronostajowa 7, 30-387, Kraków, Poland.
    Recent studies revealed the cooperation between peroxisome proliferator-activated receptor gamma (PPARγ) and α-MSH signaling, which results in enhanced melanogenesis in melanocytes and melanoma cells. However, the agonists of PPARα, such as fenofibrate, exert depigmenting effect. Therefore, we aimed to check how the PPARα expression level affects the antimelanogenic activity of fenofibrate and whether PPARα modulates melanogenesis independently of its agonist. Read More

    The Methoxyflavonoid Isosakuranetin Suppresses UV-B-Induced Matrix Metalloproteinase-1 Expression and Collagen Degradation Relevant for Skin Photoaging.
    Int J Mol Sci 2016 Sep 1;17(9). Epub 2016 Sep 1.
    Graduate School of Biotechnology, Kyung Hee University, Yongin 17104, Korea.
    Solar ultraviolet (UV) radiation is a main extrinsic factor for skin aging. Chronic exposure of the skin to UV radiation causes the induction of matrix metalloproteinases (MMPs), such as MMP-1, and consequently results in alterations of the extracellular matrix (ECM) and skin photoaging. Flavonoids are considered as potent anti-photoaging agents due to their UV-absorbing and antioxidant properties and inhibitory activity against UV-mediated MMP induction. Read More
