A cosmetic activator system for activating a cosmetic is provided including: an activator having an energy source configured to emit an energy pulse and a controller; and an imprinter having an imprint pattern and at least one activation element configured to be in communication with the energy source, wherein the imprinter is configured to create an imprint on the cosmetic.

Photochromic formulations including a core material and a photochromic layer overlying the core material and forming a particle are provided. The photochromic layer may include a plurality of photochromic materials, including a first photo-responsive pigment characterized by reversible diffuse reflectance at a first central wavelength from 490 nm to 520 nm in response to irradiation by photons of a first characteristic wavelength, a second photo-responsive pigment characterized by reversible diffuse reflectance at a second central wavelength from 570 nm to 590 nm in response to irradiation by photons of a second characteristic wavelength, and a third photo-responsive pigment characterized by reversible diffuse reflectance at a third central wavelength from 450 nm to 495 nm and a fourth central wavelength from 625 nm to 740 nm in response to irradiation by photons of a third characteristic wavelength. The first, second, and third characteristic wavelengths may be different.

A process is provided for dyeing keratinous material. The process includes (1) providing an agent (a) that includes (a1) at least one amino-functionalized silicone polymer and (a2) at least one colorant compound. The process further includes (2) providing an agent (b) that includes (b1) water and (b2) at least one fat component. The method includes (3) preparing an application mixture by mixing agents (a) and (b) and (4) applying the application mixture to the keratinous material. Further, the method includes (5) exposing the application mixture to the keratinous material and (6) rinsing the application mixture with water.

An agent for dyeing keratinous material is provided. The agent includes (a1) at least one amino-functionalized silicone polymer and (a2) at least one color-imparting compound. Further, the agent includes (a3) at least one preservative and (a4) at least one fat component.

A process for dyeing keratinous material is provided. The process includes (1) applying a coloring agent (a) to the keratinous material. The coloring agent (a) includes (a1) at least one amino-functionalized silicone polymer and (a2) at least one colorant compound. The method further includes (2) allowing the coloring agent (a) to act on the keratinous material for a period of 15 seconds to 10 minutes, and (3) rinsing out the dye (a) under running water for a period of 15 seconds to 10 minutes. In the process, no further cosmetic agent other than the coloring agent (a) is used.

The present invention is a cosmetic or dermatological preparation comprising 0.01% by weight to 5% by weight of at least one red light-filtering dye and 0.0001% by weight to 10% by weight of at least one anti-inflammatory active ingredient. The preparation can be used for the prophylaxis and treatment of sun-irritated skin and to aid the body's own repair mechanisms.

A chromic composition adapted for application to a substrate comprising a reversible colour-change composition and a binder composition is provided. The colour change composition includes a leuco-dye and/or liquid crystal. The composition may be applied to keratinous material, polymers or other substrates to provide a colour change effect and other desirable properties such as natural feel and durability.

Agents and methods for coloring keratinous material, in particular human hair, are provided. In one example, the agent includes (a1) at least one amino-functionalized silicone polymer, (a2) at least one color-imparting compound, and (a3) at least one addition product of ethylene oxide to the esters of C.sub.12-C.sub.24 fatty acids and C.sub.1-C.sub.12 aliphatic alcohols.

A cosmetic ingredient for cosmetic products has a polymer structure which includes an emollient or film-forming cosmetic polymer which is transparent to light. An organic chromophore molecule is inserted and chemically linked into the polymer, which can be a fixed color molecule or a photochromic molecule capable of rapidly switching from one color to another. The colored or photochromic molecule is inserted and chemically linked by transesterification into a cosmetic oil provided with functionalities which are suitable for the chemical anchoring of the molecule and chemically linked to said oil. The cosmetic oil may be a silicone macrodiol functionalized with a photochromic derivative designed so as to ensure the transition between a colorless state and a colored state following irradiation with ultraviolet light.

Systems and methods for application of cosmetic designs are described. In an embodiment, the system includes a visible light mirror, comprising a first portion being at least partially transparent to visible light; a camera, optically coupled with the visible light mirror to receive visible light via the first portion; an illumination source, physically coupled with the visible light mirror and configured to emit a plurality of discrete wavelength channels; and a computer system, electronically coupled with the camera and the illumination source, and comprising one or more processors and a non-transitory computer readable storage medium storing instructions that, when executed by the one or more processors, cause the one or more processors to perform one or more methods of the present disclosure.
