There are presented topical formulations and methods of applying these formulations in therapeutically effective amounts directly to areas of the human skin to remediate and to counter effects that are commonly regarded as aging. The formulations address the effects on the skin of UV light, High Energy Visible (HEV) light, blue light, and Urban Dust as well as remediating fine lines and age-related localized melanin concentrations (age spots), improving the uniformity of skin tone (reduction in skin redness) and enhancing the brightness of the skin to provide a more youthful appearance. Skin treated with the formulations also exhibit a reduction in the depth and prominence of wrinkles, a marked reduction in harmful reactive oxygen species in the treated skin, and a reduction in lipid peroxidation caused by Urban Dust.

It is to provide a cosmetic composition comprising a coacervate droplet which can form a metastable water-in-water type emulsion. A cosmetic composition of the present invention comprises a water phase as a matrix and an oil phase dispersed therein, and stabilized by a coacervate droplet of an anionic polyelectrolyte and a cationic polyelectrolyte, the coacervate droplet being one which can form a metastable water-in-water type emulsion.

Described is a cosmeceutical formulation for treating damaged skin comprising a first hyaluronic acid having a molecular weight of from about 25 kDa to about 100 kDa, a second hyaluronic acid having a molecular weight of from about 1 kDa to about 20 kDa, and a polyglutamate. The formulation is used in methods of improving skin, including treating or repairing damaged or wrinkled skin.

The invention provides an emollient composition comprising at least one hydrocarbon fluid in an amount of 50 to 100% by weight, preferably from 80 to 100% by weight, more preferably from 90 to 100% by weight and preferably equal to 100% by weight relative to the total weight of the composition, said fluid being obtainable by a process of catalytically hydrogenating a feed comprising more than 85% by weight of oligomerized olefins, at a temperature from 115 to 195 C. and at a pressure from 30 to 70 bars.

The invention further provides a cosmetic, dermatological or pharmaceutical composition comprising at least one emollient composition according to the invention, and uses thereof.

An oil-based cosmetic contains, as an oily base, an oil containing a phytosterol derivative, having a refractive index at 40 C. of 1.50 or more, and being liquid at 25 C. (A) and a liquid silicone oil that is incompatible with the oil (A) at 25 C. (B). In addition to the oily base material, a separation inhibitor to suppress separation of the oil of the component (A) and the silicone oil of the component (B) (C) is preferably contained, and a powder (D) and a solid oil and/or lipophilic gelling agent (E) may also be contained. A form of the of oil-based cosmetic can be appropriately selected according to an application, and can be a liquid, paste, solid, or the like.

A water-in-oil-in-water (W.sub.1/O/W.sub.2) emulsion comprising a lipid phase (O) and a water phase (W.sub.2), the lipid phase being distributed inside the water phase, wherein the lipid phase contains water droplets (W.sub.1), wherein the water content inside the lipid phase is between 10 wt % and 80 wt % relative to total weight of the lipid phase, wherein the water droplets are stabilized inside the lipid phase by an emulsifier composition, wherein the emulsifier composition comprises an Acetone-insoluble (AI) component containing a Phosphatidyl Choline (PC), a Phosphatidyl Inositol (PI), a Phosphatidyl Ethanolamine (PE) and a Phosphatidic Acid (PA), wherein PC is at most 15.5% relative to the total weight of the emulsifier composition and wherein the emulsifier composition has a phospholipid weight ratio R of at most 65%, the ratio R being defined according to Formula R(in %)=100?(PC+PI+PE+PA)/AI.

The invention relates to stabilised multiple emulsions comprising the compounds a), b) and c), methods for the stabilisation of multiple emulsions and the use of multiple emulsions as skin protection products, in particular for protection against aqueous noxa, where: a) at least one aliphatic unbranched diol with 2 to 4 carbon atoms in the hydrocarbon chain, b) at least one further branched or unbranched aliphatic diol with 4 to 12 carbon atoms in the hydrocarbon chain that is different from a), whereby the hydrocarbon chain may be interrupted by an oxygen atom, c) at least one single-value aliphatic alcohol with 12 to 30 carbon atoms in the hydrocarbon chain.

The present invention concerns a water-in-oil-in-water emulsion comprising an external continuous aqueous phase and a water-in-oil emulsion in the form of droplets (G1), each droplet (G1) comprising a continuous fatty phase and at least one droplet (G2) comprising an internal aqueous phase, said continuous fatty phase containing at least one gelling agent, said droplets (G1) comprising a shell formed of at least one anionic polymer (PA1) and at least one cationic polymer (PC).

Compositions including an aqueous phase emulsified within an external fatty phase comprising at least one silicone are provided. The compositions include iron oxide having a silane-treated surface, zinc-oxide having a silane-treated surface, a titanium dioxide-silica composite particulate, and hollow spheres of acrylic polymer.

The present invention relates to a multilayer emulsion cosmetic composition which does not contain a surfactant and which exhibits excellent stability.
