Langues : Anglais (eng) Catégories : Acné L'acné (nom féminin) est une dermatose (maladie de la peau) inflammatoire des follicules pilosébacés (glandes sécrétant le sébum, à la racine des poils) avec formation de comédons.
Cette maladie de la peau est représentée dans sa forme la plus fréquente par l'acné polymorphe juvénile qui touche les adolescents, mais qui ne résume pas toutes les acnés. Il existe aussi des acnés exogènes d'origine professionnelle, médicamenteuse, cosmétique...

Régénération (biologie)Index. décimale : 668.5 Parfums et cosmétiques Résumé : 2-O-glyceryl-3-O-octyl ascorbate (GO-VC) is a stable amphiphilic ascorbic acid (AsA) derivative in which AsA is bound with octanol, which has antibacterial activity, and glycerin, which has a moisturising effect. GO-VC has effects that have not been confirmed with conventional AsA derivatives, such as antibacterial / antiviral effects and epidermal barrier function-reinforcing effect, and many clinical results of acne, wrinkle and pigmentation improving effects by doctors have been obtained. In recent years, an epidermal regeneration-enhancing effect has also been found, which leads to improvement of skin problems such as dryness, acne, wrinkles and pigmentation. In other words, GO-VC has a wide variety of skin physiological effects. Therefore, GO-VC could add various skin physiological effects by blending it in cosmetics and other preparations, and can be said to be an epoch-making AsA derivative.

Vitamine CIndex. décimale : 668.5 Parfums et cosmétiques Résumé : In cosmetic products, ascorbic acid derivatives are widely used, because of the instability of ascorbic acid (AsA) (called vitamin C as its alias). As a new nonionic and amphiphilic ascorbic-acid derivative, 2-glyceryl-3-octyl ascorbate (GO-VC), which is synthesised by introducing an octyl and a glyceryl group into ascorbic acid structure, has been recently developed. Due to its unique chemical structure, in addition to the effects of AsA, GO-VC is expected to have a humectant effect derived from glycerin and an anti-bacterial property derived from octanol, and also is highly likely to have a fibroblast activation ability, and a melanogenesis-suppressing and skin pore and wrinkle improving effect. GO-VS's safety tests, which include a human skin-sensitivity test [repeat insult patch test (RIPT)], ocular irritation test [bovine corneal opacity and permeability (BCOP) assay], genetic toxicity (Ames test), and clinical human skin patch test, have been performed, confirming the safety of GO-VC.
