The invention relates to a cosmetic composition comprising a blue dye powder containing an anthocyan, a metal ion and tannic acid and a cosmetic additive. The invention also relates to a process for making up keratin materials by applying the cosmetic composition to the keratin materials.

Makeup composition comprising a blue pigment

The present invention concerns a cosmetic method for dyeing or making up keratin fibres, in particular eyelashes and/or eyebrows and preferably eyebrows, comprising the application, to the keratin fibres, of at least: a) A dyeing cosmetic composition A comprising, in a physiologically acceptable medium, one or more natural dye(s) chosen from the group consisting of neoflavonoids, gallic tannins and catechic tannins, and/or proanthocyanidins and the derivatives of same and the mixtures thereof, or preferably one or more plant extracts containing same, and advantageously an antioxidant, b) A revealing cosmetic composition B comprising, in a physiologically acceptable medium, at least one iron salt and/or one aluminium salt, in particular an iron gluconate or an iron sulphate, composition A being applied before or after composition B, and preferably before composition B.

Method for dyeing or making up eyebrows

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

The invention relates to a process for dyeing keratin fibers, in which said fibers are treated: &#x25aa; with a composition (A) comprising i) one or more indole or indoline compounds; ii) one or more metal salts; iii) hydrogen peroxide or one or more systems that generate hydrogen peroxide; and then &#x25aa; with a composition (B) comprising iv) one or more basifying agents. The invention also relates to a hair dyeing process for obtaining better colorations, which are more uniform, chromatic and remanent and which do not impair the cosmetic properties of keratin fibers.

Hair dyeing process using a composition comprising at least one indole or indoline compound, a metal salt, hydrogen peroxide and a basifying agent

The present invention relates to a composition for the coloring of keratin fibres, notably hair, that comprises a phenoxazinone dye of formula (I) as well as the use of this dye for hair coloring. The invention thus makes it possible to obtain coloration that respects the nature of the hair and offers strong shades, which are resistant and have low selectivity.
