King of the forests, symbol of wisdom, power and immortality, the oak tree is solid and resistant to the test of time. Living up to 500 years, oak has to synthesize molecules of defence and protection for adapting to its environment. Thanks to its powerful antioxidant capacity, Phytessence™ French Oak reduces the harmful effects of oxidative stress involved in skin and scalp ageing. Hair follicles are the target of radical peroxide attacks which cause bleaching and loss of vitality of hair and the slowdown in its growth. The protective effect of the extract has been tested on hair follicle cells submitted to oxidative stress induced by lipid peroxide. Phytessence™ French Oak reduces by 78% the production of free radicals responsible for the premature ageing of hair follicle. Also tests have been carried out on skin to show that Phytessence™ French oak reduces free radical production after UVA exposure of the skin.
