In 2017, Cosmetics Europe performed a double-blinded ring test of 24 emulsion-type sunscreen products, across 3 in vivo test laboratories and 3 in vitro test laboratories, using a new candidate in vitro SPF test method. Based on the results of this work, an article was published showing how data derived from a new lead candidate method conform to new International Standards (ISO) acceptance criteria for alternative SPF test methods. Of the 24 sunscreen products tested, the majority of emulsions ...
OBJECTIVE: Tyrosinase is the rate-limiting enzyme in melanogenesis. Thiamidol is the most potent inhibitor of human tyrosinase out of 50,000 tested compounds. In clinical studies, it was shown to improve facial hyperpigmentation, post-inflammatory hyperpigmentation, and age spots significantly. To identify the optimal number of daily Thiamidol applications, we conducted a split-face study comparing the efficacy and tolerability of four-times with two-times daily application. Subsequently, we eva...

OBJECTIVE: The aim of this work was to investigate an alternative hair dyeing method with vegetable colorants as the tannins, as well as the impact of pre-treatment as the bleaching process. METHODS: Untreated, 1, 2 and 3 times bleached hair tresses which were dyed with tannins in combination with metal salts were characterized. The wash fastness and the color-strength of the vegetable dyed hair tresses were spectrophotometrically investigated. RESULTS: To determine the color strength KS and the...

OBJECTIVE: Yerba Santa (Eriodictyon angustifolium and Eriodictyon californicum) has been used for many years in traditional medicine. However, the effect of Yerba Santa on melanogenesis has not yet been investigated. We aimed to assess the biological effects of Yerba Santa on hair pigmentation. METHODS: Yerba Santa extracts were assessed for their cytological effects following X-ray irradiation treatment, and then tested directly for the prevention of human hair graying. Ultra-performance liquid...
OBJECTIVE: During the development of cosmetic formulations, in vitro and in vivo methods are essential tools used to reliably assess the skin irritation potential of a product or ingredient. Epicutaneous patch testing (single and/or multiple application protocols) has long been used as an initial in vivo method to screen for possible skin irritation properties of a substance or formulation. To confirm the mildness and dermatological and/or consumer acceptance of a product use tests are often sub...
OBJECTIVE: The circadian rhythm was set into focus by awarding the Nobel Price of Physiology/Medicine to Jeffrey Hall, Michael Rosbash and Michael Young in late 2017. Numerous publications elucidated the molecular mechanisms driving the circadian biorhythms of our body, peripheral organs and each single cell. However, there is minor knowledge on the circadian rhythm of the skin, which has its own peripheral circadian clock in contact with cosmetic formulations. The skin's epidermal clock is exce...
OBJECTIVE: Few histological studies have directly examined age-related changes within the lips, although noninvasive investigations of such changes are increasing. Therefore, this study aimed to provide histological and molecular data on age-dependent alterations in the vermilion. METHODS: Upper vermilion specimens from 15 female Caucasian cadavers (age range, 27-78 years) were investigated histologically or immunohistochemically. RESULTS: Histologically, age-dependent decreases in areas occupie...

OBJECTIVES: To evaluate improved protein extraction and two-dimensional electrophoresis (2DE) separation methods with Japanese reference human hair (JRH). To determine if fibre curvature is related to protein composition in curly and straight Japanese women's human hair (JHH) samples. To identify proteins from JRH 2DE maps and expression differences between curly and straight JHH. METHODS: Hair keratin and keratin-associated proteins (KAPs) were extracted intact with dithiothreitol or tris(2-car...
