This patent document discloses a kit containing abase component and an activating component for cosmetics, therapeutic and aesthetic application purposes. The kit, comprised innovative technology, ingredients, and formulations that overcome the drawbacks of unviable, unpractical, unwearable and unmarketable products, enables a film-formed “young-looking skin” to cling onto the real skin for much longer period of time, and is truly wearable and viable to the consumers for achieving the benefits of dramatically reducing or diminishing eye bags, dark circles, enlarged pores, wrinkles, age spots, and so on with desired and rapid results. The film is comfortable, invisible, safe, non-invasive and easy to wear.

The present invention relates to a cosmetic-supporting structure, including a reticulated porous foam and a silicone coating layer, serving as an outer frame, on an outer surface of the foam, serving as an inner frame, a method of manufacturing the same, and a cosmetic product containing the same.

The invention provides a new method for preparing ultra-small polymeric-lipidic delivery nanoparticles (USDNs) that were synthesized by a nanoprecipitation method followed by a layer-by-layer nanodeposition. The USDNs particle size can be controlled between 5-25 nm and provides loading capacities of 22.12% to 72.08%. Moreover, the USDNs platform provides pH controlled drug release, within a terminal release ratio of 68% at pH 5.0 and almost no release to pH of 7.5. Furthermore, based on their small sizes (5-25 nm) and unique composition, the USDNs penetrates the skin strata efficiently, release the payload at the target site as topical or transdermal treatment of a variety of skin disorders. Additionally the USDNs system can be used to treat and diagnoses other crucial diseases (Cancer, Alzheimer, etc) can be combined with various micro-needles or needles free array technologies for special application.

The present invention relates to effect pigments which are based on flake-form substrates having a circular form factor of 1.2-2 and are coated with at least one high-refractive-index layer, and to the use thereof, inter alia in paints, coatings, printing inks, plastics and in cosmetic formulations.

The invention relates to an absorbent effect pigment including a nonmetallic substrate in platelet form and a coating applied thereto, wherein the coating includes at least one spacer layer. The invention further relates to a process for production of and to the use of the absorbent effect pigment.

The present invention provides a glitter pigment capable of simultaneously achieving electromagnetic wave transmission properties, a high reflectance in appearance, and a neutral color in appearance. The glitter pigment according to the present invention includes: a glass flake 1; and a titanium oxide layer 2 and a silver layer 3 formed in this order on the glass flake 1, wherein a product of the optical thickness of the glass flake 1 and the optical thickness of the titanium oxide layer 2 is 61000 or more and 66000 or less when the optical thickness is expressed in nm, and the silver layer 3 has a physical thickness of 35 nm or more and 55 nm or less.

The present invention relates in particular to a cosmetic composition for the care and/or make-up of keratinous materials, in particular the skin, comprising an aqueous phase and at least one combination with optical correction effect adapted to all skin complexions comprising at least one soft-focus effect filler, at least one composite pigment, and at least one reflective particle.

An inorganic, non-quarter wave, heterogeneous multilayer effect pigment includes a platy substrate comprising an absorbing optically active metal oxide layer thereon, having an optical thickness from about 20 nm to about 400 nm; a layer of low refractive index material on the absorbing optically active metal oxide layer and having an optical thickness from about 10 nm to about 500 nm; and an outermost optically active layer of a non-absorbing high refractive index material on the low refractive index material and having an optical thickness from about 50 nm to about 1000 nm. The multilayer effect pigment exhibits a blue reflectance ratio (BRR) of at least 3, according to the equation: BRR=(Blue Max)/(Green Min); where Blue Max is the maximum reflectance exhibited over wavelengths 380 nm to 450 nm; and Green Min is the minimum reflectance exhibited over wavelengths 450 nm to 600 nm.

The present invention relates to pigments based on multicoated flake-form substrates which are distinguished by the fact that at least 8 layers [layers (A)-(H)] are on the substrate, where an SiO.sub.2 layer (=layer A) is located directly on the surface of the substrate, and to the use thereof, inter alia, in paints, surface coatings, automobile paints, powder coatings, printing inks, security printing inks, plastics, ceramic materials, glasses, paper, in toners for electrophotographic printing processes, in seed, in greenhouse sheeting and tarpaulins, as absorbers in the laser marking of paper and plastics, and in cosmetic formulations, for the preparation of pigment pastes with water, organic and/or aqueous solvents, for the preparation of pigment compositions and dry preparations.
