Abstract:
The vesicles are prepared from a lipid phase containing a mixture of nonionic amphiphilic lipids consisting of a mixture of esters of at least one polyol chosen from the group composed of polyethylene glycol containing from 1 to 60 ethylene oxide units, sorbitan, sorbitan bearing 2 to 60 ethylene oxide units, glycerol bearing 2 to 30 ethylene oxide units, polyglycerols containing 2 to 15 glycerol units, sucroses, and glucoses bearing 2 to 30 ethylene oxide units and of at least one fatty acid containing a saturated or unsaturated, linear or branched C.sub.5 -C.sub.17 alkyl chain, the number of alkyl chains per polyol group being between 1 and 10, the mixture being stabilized with ionic amphiphilic lipid or lipids chosen from the group composed of those which impart a pH of between 5.5 and 7.5 to the dispersion.
Abstract:
Compositions comprising a first dispersion of lipid vesicles which are capable of penetrating into the deep layers of the skin and which contain at least one active agent chosen from moisturizing agents, anti-free-radical agents, keratolytic agents, protides, enzymes, anti-elastase agents and anti-collagenase agents, and fatty acid derivatives, for treating these deep layers, and a second dispersion of lipid vesicles which are capable of penetrating into the surface layers of the skin and which contain at least one active agent chosen from keratolytic agents, tensioning agents, moisturizing agents, surface-restructuring agents and anti-free-radical agents, for treating these surface layers, are effective for combating ageing, acting simultaneously on the surface layers and deep layers of the skin.
Abstract:
A composition comprising a first dispersion of lipid vesicles capable of entering the deep layers of the skin and containing at least one first active substance capable of treating these deep layers, and a second dispersion of lipid vesicles capable of entering the surface layers of the skin and containing at least one second active substance, different from the first active substance, capable of treating these surface layers is found effective for anti-age, anti-wrinkle, depigmenting, nutrient, slimming, hydrating, anti-ache, antimycotic, anti-dermic and anti-psoriatic treatment.
Abstract:
A composition comprising a first dispersion of lipid vesicles which are capable of penetrating into the deep layers of the skin and which contain at least one active agent selected from the group consisting of anti-pigmenting agents, depigmenting agents and tyrosinase inhibitors, for treating these deep layers, and a second dispersion of lipid vesicles which are capable of penetrating into the surface layers of the skin and which contain at least one active agent selected from the group consisting of keratolytic agents, moisturizing agents and protective agents, for treating these surface layers, is found effective for depigmenting skin.
Abstract:
The process consists in dissolving a corticosteroid in the lipid phase of nonionic amphiphilic lipid vesicles consisting of one or more lipid lamellae.Composition for carrying out the above process, in which the vesicles are dispersed in an aqueous phase D, have an average diameter of between 10 and 5,000 nm and contain as corticosteroids 17- and/or 21-mono- or -diesters of hydrocortisone, cortisone, prednisone, prednisolone or 6-methylprednisolone, the corticosteroids representing 0.5 to 2.5% by weight of the total lipids of the lamellae.
Abstract:
The present patent application relates to a composition for topical application in the form of an oil-in-water emulsion comprising an oily phase dispersed in an aqueous phase, characterized in that it comprises at least one noncrosslinked amphiphilic polymer, the globules of the said emulsion exhibiting a mean size ranging from 15 to 500 microns and the oily phase being present in an amount of less than 35% by weight, with respect to the total weight of the composition.
Abstract:
The present invention relates to the use, especially the cosmetic use, of at least one monosaccharide chosen from mannose, rhamnose and a mixture thereof, for reducing or preventing the signs of ageing of the skin or its integuments. The present invention also relates to a cosmetic composition and a device containing it.
