Antiâge Cosmétiques Dermo-pharmacie Formulation (Génie chimique) Ingrédients cosmétiques Peau -- Soins et hygiène Vitamine B9La vitamine B9, autre nom de l'acide folique (folate, folacine ou vitamine M, acide pteroyl-L-glutamique, pteroyl-L-glutamate et acide pteroylmonoglutamique), est une vitamine hydrosoluble.
L'acide folique est le précurseur métabolique d'une coenzyme, le tétrahydrofolate (FH4 ou THF4), impliquée notamment dans la synthèse des bases nucléiques, purines et pyrimidines, constituant les acides nucléiques (ADN et ARN) du matériel génétique. Le THF intervient également dans la synthèse d'acides aminés tels que la méthionine, l'histidine et la sérine. (Wikipedia)

Résumé : |
If skin aged counter-clockwise when people turned 35 years, not only would consumers select their cosmetic products differently but also the whole cosmetic industry would have to offer completely different product categories. Of course this is just an attractive idea. Ageing proceeds in one direction and the skin unfortunately often shows the most obvious signs of ageing. The major telltale signs are reduced elasticity, poorer structure and appearance of wrinkles. Reduced turnover of skin cells and exposure to environmental factors (such as UV light), speeding up the process of skin ageing, are essential causes. It is recognised that especially the more deeply penetrating UVA light triggers cutaneous photo-ageing by a pathway that starts in dermal fibroblasts with alterations of (mitochondrial) DNA.1 A strategy helping to slow down premature skin ageing would therefore involve stimulation of skin cells such as fibroblasts, while preventing DNA damage at the same time. Several substances are known to help slow down premature skin ageing by antioxidant activity, by stimulating collagen synthesis or by other specific mechanisms. None of the vitamins or anti-ageing ingredients used so far in cosmetic formulations could demonstrate modulation of the DNA repair mechanism. The B vitamins are a class of vitamins the cosmetic industry would not go without. The well-known vitamin B5 (panthenol), vitamin B3 (niacinamide) and vitamin B6 (pyridoxin HCl) have been used for years in personal care products because of their benefits for skin and hair. Only vitamin B9 (folic acid) remained the least tapped for cosmetic applications. |
