The invention also concerns a cosmetic method for caring for and/or making up a keratinous substance, which consists in applying, to the surface of said keratinous substance, at least one composition as defined above and more particularly a cosmetic method for: a) limiting the darkening of the skin and improving the colour and uniformity of the complexion, and b) treating aging of keratinous substances.
Abstract:
The present invention relates to a cosmetic and/or dermatologigal composition comprising in a physiologically acceptable medium at least one merocyanine derivative of formula (1) or (2) and/or its E,E-, E,Z- or Z,Z-geometrical isomer forms: comprising specific polar groups consisting of hydroxyl- and ether-functionalities. Another object of the present invention relates to a cosmetic process for controlling and/or improving the darkening of the skin under exposure to UV radiation and the homogeneity of the colour of the complexion which comprises the application onto the skin of a cosmetic composition as above defined. Another object of the present invention relates to a cosmetic process for protecting the keratinic materials and particularly the skin against photo-ageing which comprises the application onto the keratinic material of a cosmetic composition as above defined.

L'invention concerne également leurs applications à la protection de la peau et des cheveux contre les effets du rayonnement ultraviolet.
Abstract:
Skin or superficial body growth cosmetic composition containing a dispersion of solid particles in a binder, in which at least one part of said particles, especially the mineral filler and/or mineral pigments are introduced into said composition in the form of particles, the surface of which is coated with at least one cationic polymer. Said compositions are stable and are characterized, in particular, by a good stability and adhesion on the skin or integuments.
Abstract:
The invention relates to a skin-colouring method in which the following elements are applied to the skin, namely: a compound or group of compounds, A, which can be condensed in situ and which have at least one free reactive function FA following condensation; and a skin-colouring agent, C, including a reactive function Fc that can form a covalent bond upon reaction with function FA.
Abstract:
The present invention relates to a cosmetic composition containing: - at least composite particles having a mean size between 0.1 µm and 30 µm, comprising a matrix and an inorganic UV screening agent, the weight content of inorganic UV screening agent in a particle being between 1% and 70%, preferably between 2% and 65%, and better still between 3% and 60%, and - at least one dispersing surfactant having an HLB of greater than 6 at 25°C, in a single-phase or multi-phase medium comprising at least one anhydrous phase containing at least one polar oil.
