Abstract: The present invention relates to a cosmetic and/or dermatological composition comprising as an active ingredient at least one glycosylated flavonoid, characterized in that it further comprises, as an active ingredient, a compound capable of limiting or preventing the penetration into the keratinocytes of a polycyclic aromatic hydrocarbon such as benzo[a]pyrene, cyclopenta[c,d]pyrene, dibenzo[a,h]anthracene or dibenzo[a,l]pyrene and/or a compound characterized by its ability to absorb blue light.

Abstract: The present invention relates to a cosmetic or pharmaceutical composition comprising N-acetylglucosamine-6-phosphate or a salt thereof and, optionally, a compound of the vitamin A family, and also to a device containing same.

Abstract: The present invention relates to the use of a DOR ligand for stimulating pigmentation in a cosmetic composition and to the use of rubiscolin-6 or its derivatives in a cosmetic composition.

Abstract: A high-tolerance biocompatible and bioregulatory dermic and/or cosmetic galenic base contains, in the aqueous phase thereof, at least two polyols selected from osides, oses or reduction products of oses, wherein at least two of the polyols are selected from reduction products of oses that are mannitol and xylitol. A dermic and/or cosmetic galenic base includes a fatty phase including a substance selected from lipo-regulatory substances. Polyols selected from osides, oses or reduction products of oses in the aqueous phase of a dermic and/or cosmetic base improve the tolerance thereof and optimize the active effects thereof. A cosmetic and/or dermo-cosmetic composition includes a base according to the invention.

Abstract: The invention relates to a cosmetic composition comprising a bio-active system which combines (i) a stable form in aqueous solution of ATP (adenosine-tri-phosphate) with optionally an ATP precursor, e.g. Gp4G (diguanosine tetraphosphate), or Ap4A (diadenosine tetraphosphate), and (ii) at least one biomimetic peptide comprising at most six amino acids, mimicking a cutaneous polypeptide or a cutaneous protein, or a biomolecule which is agonist or antagonist in relation to the aforementioned polypeptide or protein. According to the invention, the composition takes the form of a water-in-oil or oil-in-water emulsion, the bio-active system being included in the aqueous phase.

Abstract: The invention concerns a method of binding a product to the membrane of a melanocyte by means of a ligand-receptor bond, which comprises using a product consisting of a basic structure coupled to at least one ligand consisting of an oside residue accessible to the membrane receptors, said oside residue being a fucose residue, notably an Alpha-L-fucose residue.

Abstract: The invention relates to products which are to be bound specifically to the membrane of a keratinocyte by means of a ligand-receptor bond.These products carry at least one ligand consisting of an oside residue selected from .alpha.-L-rhamnose, .alpha.-D-galactose and .alpha.-D-galactose-6-phosphate.By virtue of this specificity, it is possible to prepare cosmetic or pharmaceutical compositions having an improved efficacy in particular, for example for regeneration of the epidermis, for the treatment of psoriasis or for renewed hair growth.

Abstract: The present invention relates to a composition based on hydrated lipidic lamellar phases or on liposomes.In this composition, pregnenolone or a pregnenolone ester, such as, in particular, pregnenolone acetate, sulfate or palmitate, is at least partially incorporated in the said hydrated lipidic lamellar phases or the said liposomes.This composition can be applied in particular in the cosmetic or pharmaceutical sector, especially the dermatological sector, for the preparation of compositions with regenerating or revitalizing activity.

Abstract: A cosmetic or dermatological composition comprising an extract of kola seeds substantially free of methylxanthine. Other embodiments include a composition comprising liposomes or hydrated lipidic lamellar phases containing an extract of kola seeds having a methylxanthine content or containing an extract of kola seeds substantially free of methylxanthine. Methods for treating cellulitis deposits present on body parts by application of the compositions of the present invention are also disclosed.

Abstract: This invention relates to a composition comprising hydrous lipidic lamellar phases or liposomes containing, as an active agent a retinoid or a structural analogue of retinoid, such as a carotenoid or tretinoin. These compositions are more efficient against acne and less irritant for the skin and they are used as a pharmaceutical composition, notably dermatological or cosmetic.

Abstract: The invention concerns a method of homogenizing dispersions of hydrated lipidic lamellar phases and suspensions obtained thereby which can be applied particularly to the making of products intended for cosmetic, pharmaceutical and medical uses.The method consists in dispersing in a dispersion liquid a lipidic phase or a lipidic lamellar phase containing one or several amphiphilic lipids and then in homogenizing the said dispersion by feeding the same under a pressure comprised between 10,000 and 70,000 kPa into a passageway of small width defined between the walls of an orifice and the edges of an obturating element arranged in the section of the orifice adjustably, against the flow of the dispersion.

Abstract: The invention relates to a method for preparing a pulverulent mixture of amphiphilic lipidic constituents and possibly of hydrophobic constituents, as well as to a method for producing hydrated lipidic lamellar phases from the pulverulent mixture.The method comprises dissolving the amphiphilic lipidic constituents and the hydrophobic constituents in an appropriate solvent and then atomizing said solution in a flow of gaseous fluid to produce the pulverulent mixture. The mixture thus obtained is a homogeneous and very fine powder which can be very easily dispersed in a suitable aqueous dispersion medium to produce either slightly hydrated lipidic lamellar phases or highly hydrated lipidic lamellar phases such as liposomes useful in the pharmaceutical and cosmetic fields.
