Abstract: An extract is from the plant Ravenala madagascariensis. The sap from the plant Ravenala madagascariensis or of an extract of that plant is used as a hydrating active agent in a cosmetic composition, to restore, maintain or reinforce the hydration state of the skin.

Abstract: The present inventor relates to an electrochemical device for measuring the redox state of the skin, comprising at least one working electrode, such as a microelectrode, a counter electrode, and a reference electrode, said electrodes all being fixed into a single support intended to allow each of said electrodes to be simultaneously brought into contact with the surface of the skin to be tested, the electrodes being connected, on the one hand, to a means for imposing a defined voltage between the working electrode and the reference electrode, such as a potentiostat, and, or the other hand, to a device for measuring the intensity of the current generated at the working electrode by the detection of redox species. The invention also related to a method of measuring the redox state of the skin.

Abstract: Cosmetic compositions with anti-free radical activity have been developed. Such compositions preferably contain an association of at least the following three substances with anti-free radical activity: an extract of emblica, idebenone and N-acetylcysteine.

Abstract: Cosmetic compositions with anti-free radical activity have been developed. Such compositions preferably contain an association of at least the following three substances with anti-free radical activity: idebenone; N-acetylcysteine, and alpha-tocotrienol or an ester thereof with a C2-C4 organic acid.

Abstract: The present invention relates to the use, in a cosmetic composition, of an extract of at least one part of an orchid of the species Vanda coerulea, as an agent for maintaining or restoring the hydration state of the skin, said composition also containing a cosmetically acceptable excipient. This skin hydrating effect is obtained in particular by stimulating the expression of aquaporin 3 and of the LEKTI protein. The invention also relates to a cosmetic skincare method for the purpose of improving the hydration state of said skin.
