Surma, Auteur ; Christian Klose, Auteur Année de publication : 2017 Article en page(s) : p. 2-6 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Dermatologie Lipides Peau -- analyse Vieillissement cutané Index. décimale : 668.5 Parfums et cosmétiques Résumé : The lipid composition of human skin is essential for its fonction ; however the simultaneous quantification of a wide range of skin lipids, belonging to both stratum corneum and sebum, is not trivial. Recently we developed a new, "shotgun" mass spectrometry-based method characterized by a broad coverage of lipids, absolute quantitation, high reproducibility and high-throughput providing comprehensive insight into skin lipid composition. We applied this method in a large-scale study of natural lipid variability of human skin. in this study we analyzed samples from 104 individuals of both sexes of different ages. We discovered gradual changes in the skin lipidome correlated with age but no sex-specific differences. Our novel method enables detailed and broad insights into skin lipidomes, both in terms of lipidome coverage and sample number. Therefore, skin shotgun lipidomics has the potential to become useful in studies related to ski aging and anti-aging product claims support. Note de contenu : FIGURES : Inter-individual variation. (1A,1B) Amounts of lipids measured of (1A) males and (1E) females of different age (here the two most extreme pmol values are sot shows to improve clarity). Lines represent 0-order polynomial smoothing fonction with 8 neighbors averaged. (1C,1D) Profiles of lipid groups of (1C) males and (1D) females of different age. Lines represent 0-order polynomial smoothing function with 8 neighbours averaged. (1E) Principal component analysis of males and females of different age lipidomes with lipid sub-species as input. (1F) sex prediction accuracy (test error) of random Forest classification with all lipid data and data excluding sebum lipids. Points show individuel results of a 5 times repeated 10 times cross validation with horizontal lines representing their mean. The dashed line is the 0.65 Null Error Rate, the prediction error was based on always choosing the majority class.

Maslinic acid : The secret of longevity / Elena Grau in SOFW JOURNAL, Vol. 143, N° 9 (09/2017)  

[article]  inSOFW JOURNAL > Vol. 143, N° 9 (09/2017) . - p. 8-14 Titre : Maslinic acid : The secret of longevity Type de document : texte imprimé Auteurs : Elena Grau, Auteur Année de publication : 2017 Article en page(s) : p. 8-14 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Antiâge Biomolécules actives Dermo-cosmétologie Maslinique, Acide Peau -- Soins et hygiène Index. décimale : 668.5 Parfums et cosmétiques Résumé : The skin, as the protective barrier that separates and isolates the inner from the outer environment, suffers the consequences of the intrinsic factors of aging (oxidative stress, glycation, inflammation etc), as well as those produced by the so-called extrinsic factors (ionizing radiation, UV-B, pollution, tobacco, eating style etc) ail of which may alter its condition and function. As a consequence, skin may undergo changes leading to photoaging, inflammation, immune dysfunction, imbalance in epidermal homeostasis and other disorders. Recent studies on the field of epigenetics show that the skin undergoes a series of damages that end up accumulating with time and undermine the proper functioning of cells. Our genes lose the ability to meet the necessities and therefore they become ineffective in repairing the damage when and where is needed. It is well known that from the age of 40, the skin starts losing its density and firmness : production of collagen, elastic fibres and filler substances that lend volume to the skin are drastically reduced, proinfiammatory processes increase and cells do not work properly.

Stimulation of epidermal basal cells for a renewed skin / Alicia Giménez in SOFW JOURNAL, Vol. 143, N° 9 (09/2017)  

[article]  inSOFW JOURNAL > Vol. 143, N° 9 (09/2017) . - p. 16-18 Titre : Stimulation of epidermal basal cells for a renewed skin Type de document : texte imprimé Auteurs : Alicia Giménez, Auteur ; Olga Laporta, Auteur ; Elena Cañadas, Auteur ; Albert Soley, Auteur ; Raquel Delgado, Auteur Année de publication : 2017 Article en page(s) : p. 16-18 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Antiâge Biomolécules actives Dermo-cosmétologie Epiderme Peau -- Soins et hygiène Régénération (biologie) Index. décimale : 668.5 Parfums et cosmétiques Résumé : The epidermis is one of the most active tissues in terms of regeneration. Epidermal basal cells are mostly responsible for preserving the self-renewal properties of the skin, with age, these cells lose their efficiency, leading to a slowdown of the division process, a reduction of functional keratinocytes and the consequent emergence of aging signs on the skin. In order to help reactivate basal cells and to allow the self-renewing properties of the epidermis last longer, a cosmetic active ingredient was developed inspired by epigenetics. This ingredient can assist in the reactivation of basal cells for an accelerated turnover of the epidermis. When evaluated on the skin of volunteers a smoother, a more radiant and younger-looking appearance was observed.

Modern cosmetics need adequate solutions for an extended solar protection to fight against the harmful impact of the complete range of radiation (UV, VIS and IR) due to an over exposure. In this study, we focus on the additional performance of UV filter grade titanium dioxide in high energy visible light (HEVL) and IR-A light investigated by photometric measurements in vitro on different substrates. This paper provides information on types of titanium dioxides that are suitable to optimize your formulation and provide advanced light protection with excellent results in HEVL and IR-A ranges.

Safety, quality and impact of cosmetics / Klaus Henning in SOFW JOURNAL, Vol. 143, N° 9 (09/2017)

In online forums, blogs and social media knowledge is imparted for professional cosmetic applications. The user wants a credible reason for his product application. Social Media Marketing is also important for the Chinese market where 52.2% of the population are internet users. In China for cosmetics imports and product registrations legal regulations exist. The same applies for the export to Iran. The green aspects of the cosmetics market and the sustainability concept are an issue starting at the raw material sourcing up to energy and water-saving consumer products. The safety of cosmetics in the application concerned to reports on the SCCS Notes of Guidance, the safety assessment of cosmetic raw materials, the development of CMR substances of cosmetics legislation, reporting of unwanted side effects and an experience report on GMP. Production related impacts on the conservation arise by changes in pH-value or by incompatibility of components. By combination with biocide boosters the needed quantity of preservatives can be reduced without compromising the antimicrobial efficiency. For the marketing of cosmetic products proofs of effectiveness are required for the verifiability and the product advertising in accordance to the EU Cosmetic Directive and EU Claims Directive, respectively.
