A regime or regimen for artificially coloring the skin entails topically applying thereon at least a) dehydroascorbic acid and/or a monomeric derivative thereof of formula (I) below and/or an isomeric form thereof of formula (I') below and/or a polymeric derivative thereof: in which:

Dehydroascorbic acid or monomeric, polymeric or isomeric derivative thereof and an amine for artificially coloring the skin

Dehydroascorbic acid and polymeric/monomeric derivatives and isomers thereof are useful for artificially coloring the skin and more particularly as a skin self-tanning agent; the dehydroascorbic acid may be formed 'in situ' from ascorbic acid or a derivative or salt thereof via chemical oxidation and/or via enzymatic oxidation, and a two-component agent thereof includes

Application of dehydroascorbic acid or derivatives/isomers thereof for artificially coloring the skin

Expression of a messenger RNA which encodes a protein which is expressed by differentiated cells, notably the cells of the skin or appendages thereof, is inhibited by topically administering to said differentiated cells a thus effective amount of at least one double-stranded RNA oligonucleotide, formulated into a topically applicable, physiologically acceptable medium therefor; such regime or regimen is useful for treating a variety of afflictions or conditions, e.g., combating the signs of skin aging, stimulating hair growth or retarding loss thereof, inhibiting cellular proliferation and/or differentiation, etc.

Topical administration of at least one double-stranded RNA oligonucleotide (dsRNA)

A substrate is filled with a reagent that presents a stable free radical character, and that is capable of producing a visible reaction in the presence of at least one free radical scavenger analyte of the skin.

Method of evaluating the potential of the skin for scavenging free radicals

Processes for coloring a keratin material, comprising applying to the keratin material, in the presence of oxygen, at least one component (A) comprising, in a physiologically acceptable medium:&#x2014;at least one dye precursor chosen from compounds comprising at least one aromatic ring comprising at least two hydroxyl groups borne by two successive carbon atoms of the at least one aromatic ring, and at least one catalytic system comprising at least one first catalyst () chosen from Mn(II) and Zn(II) salts and oxides and/or at least one second catalyst () chosen from alkali metal hydrogen carbonates and alkaline-earth metal hydrogen carbonates followed by applying at least one component (B) comprising at least one acidic composition to fix the shade and followed by applying at least one component (C) comprising at least one alkaline composition to increase the intensity of the color or to modify the shade and optionally fixing the new color or shade obtained by applying a new application of at least one composition (B).

Composition for coloring a keratin material, comprising at least two components, and coloring processes

Disclosed methods and systems related to enabling an analysis using a three-dimensional facial image. One of the methods involves facilitating construction of a three-dimensional facial image using at least captured image of a subject's face. The method also involves facilitating a simulation of use of an aesthetic feature on the three-dimensional facial image and/or processing of the three-dimensional facial image to enable a beauty analysis.

Analysis using a three-dimensional facial image

A method of performing a beauty analysis is disclosed. The method comprises receiving information of at least one portion of a subject's external body condition, identifying in the information at least one condition, extracting from the information at least one feature of the at least one condition, and storing extracted information reflective of the at least one feature.

Feature extraction in beauty analysis

Described is a method of reducing transcutaneous passage of an orthodiphenol oxidation dye by adding a catalytic system of Mn(II) or Zn(II) salt or oxide and at least one alkaline or alkaline earth hydrogenocarbonate to the orthodiphenol oxidation dye composition.

Coloring composition for keratin fibres comprising a system limiting the transcutaneous passage of an oxidation dye

A method, device and system for determining skin type. The method includes a step of applying at least one drop of substance onto a zone of the skin or on a collector member previously in contact with the zone of the skin. The substance can modify at least one physicochemical property of the surface of the zone or of the collector member exposed to the substance. After the drop has disappeared or been removed, the extent of the surface is evaluated and the skin type is determined as a function of this evaluation.

Method, system and device for evaluating skin type

The composition comprises, in a physiologically acceptable medium, an efficient amount of at least one colouring agent precursor selected among the compounds comprising at least one aromatic cycle having at least two hydroxyl groups carried by two consecutive carbon atoms of the aromatic cycle, optionally an amino acid comprising at least one thiol group and an efficient amount of a catalytic system comprising a first component selected amongst salts and oxides of Mn(II) and/or Zn(II) and/or the mixtures thereof and a second component selected amongst alkaline hydrogenocarbonates, alkaline earth hydrogenocarbonates and the mixtures thereof, the proportions of the first component and the second component being such that: Application for colouring skin and/or keratin matters.

Dyeing composition, method for obtaining the same and use for coloring the skin and/or keratinous fibres

The present invention includes a method for predicting evolution of at least one condition of an external body portion of a subject. The method may include receiving first data, receiving second data, generating a forecasted or expected evolution of the at least one condition of the external body portion of the subject based on the first data and the second data, and transmitting to the subject the forecasted evolution. The first data may be representative of at least one condition of the external body portion of the subject in a first time frame. The second data may be representative of the at least one condition of the external body portion of the subject in a second time frame occurring after the first time frame. A beauty product may be applied to the external body portion between the first and second time frames.
