The invention relates to a process for the preparation of a cosmetic or dermatological active principle, comprising the culturing of at least one nonphotosynthetic and nonfruiting filamentous bacterium on a medium comprising at least one nonsulphurous mineral and/or thermal water. It also relates to a cosmetic or dermatological composition comprising at least one bacterium of the genusor one of its extracts.

Process for the preparation of active principles on thermal water and compositions comprising them

A skin microbiota modulation device that includes a cold plasma assembly configured to generate a cold plasma stimulus including a partially ionized gas mixture and to interrogate a biological surface with the cold plasma stimulus; and a microbiota seeding assembly including one or more target species of micobiota, the microbiota seeding assembly configured to deliver the one or more target species of micobiota to the biological surface.

Cold atmospheric plasma treatment with chemical or organic compounds to modify the keratinous substrate microbiota

This invention relates to the use ofto elicit a plant cell of an Iridaceae and the use of these elicited cells in treating sensitive skins.

Use of elicited iridaceae plant cells in the treatment of sensitive skin

The present invention relates to the cosmetic use of dedifferentiated plant cells of a plant of thesp. genus, or of an extract or a lyophilizate of said cells, as an active agent for caring for aged skin or aged hair. It also relates to rose dedifferentiated cells, in particular Lanc&#xf4;me rose dedifferentiated cells.

Cosmetic use of dedifferentiated plant cells

The present invention relates to the cosmetic use of a lysate of a bacterium or bacteria belonging to thesp. genus (in particular the species:) in a complete fermentation medium, as an active agent for preventing and/or treating dandruff conditions of the scalp, including dandruff conditions of the scalp associated with a prevalence of pathogenic microorganisms on the scalp and/or an imbalance of the scalp ecoflora.

Useful active agent for preventing and/or treating dandruff conditions of the scalp

Sensitive skin, mucous membranes and scalps are treated by administering to individuals in need of such treatment, thus effective amounts of at least one extract of a non-photosynthetic and non-fruiting filamentous bacterium cultured in a medium which includes at least one non-sulfurous mineral and/or thermal water, e.g., an extract derived from the bacterium, in particular the strain ATCC 15551, cultured in a medium enriched with water from La Roche Posay.

Bacterial extracts cultured in thermal waters for treating sensitive skin, mucous membranes and scalps

Compounds of the formula: and compositions containing one or more such compounds, the compositions preferably being suitable for topical application to the skin.

Lipid A-type compound and composition containing it

The invention provides a bioreactor (10) for the culture of animal, vegetable, microbial of algal cells of their co-cultures, of the type including a body (12) which delimits an internal volume (14) capable of holding a culture liquid (16) and a gas volume (17) above the culture liquid (16), and which includes means for introducing (18) and/or extracting (20) elements respectively into and/or out of the internal volume (14) of the body (12), and of the type which includes means (22) for driving the body (12) in an oscillating movement so as to obtain agitation of the culture liquid (16), characterised in that the body (12) is a rigid vessel.

Bioreactor forming a rigid vessel

The present invention relates to the use for dyeing keratin fibers, in particular human keratin fibers such as the hair, of a dye precursor bearing at least one phosphate substituent of formula &#x2014;O&#x2014;PO(OH), in the presence of at least one acid or alkaline phosphatase.

Phosphate dye precursors and use thereof for dyeing keratin fibers

Use of an extract of bacterium from the family Pseudomonadaceae in the production of cosmetic compositions in particular for combating ageing of the skin.

Use of bacterial extracts of the pseudomonadaceae family as cosmetic agents

The invention concerns the use in a cosmetic composition or for preparing a pharmaceutical composition of at least a plant extract of the genus Chrysanthemum for stimulating skin and/or hair pigmentation. The invention also concerns a composition containing at least one active principle and an extract of at least a plant of the genus Chrysanthemum.

Use of at least one extract of the genus chrysanthemum for assisting skin and/or hair pigmentation

Disagreeable/objectionable odors, notably body and sweat odors, are inhibited by treating the situs of same, for example the skin, hair and/or mucous membranes of a human subject, with hygienic/deodorant compositions comprising effective odor-/body odor-inhibiting amounts of at least one extract of undifferentiated plant cells.

Inhibiting disagreeable odors with extracts of undifferentiated plant cells

The subject of the present invention, in its most general aspect, is an extract of cells of at least one plant of the Iridaceae family, the said plant being obtained by in vitro culture. The subject of the invention is also compositions containing an extract of cells of at least one plant of the Iridaceae family, the use of the said extracts as antagonist of CGRP and/or of substance P and a process of cosmetic treatment involving one of the said compositions.

Iridaceae extract and compositions containing it

Human skin is artificially tanned, darkened and/or browned by topically applying thereto, for such period of time as required to elicit the desired response, an effective self-tanning/coloring amount of at least one plant of the genus Saxifraga, advantageously in association with a thus-effective amount of another skin colorant, e.g., dihydroxyacetone (&ldquo;DHA&rdquo;).

Saxifraga extracts for artificially tanning human skin

Cosmetic/pharmaceutical compositions, suitable for cosmetic applications and/or for treating a wide variety of mammalian disorders or disease states, comprise an effective active principle amount of a clarified and stabilized culture medium for at least one non-photosynthetic filamentous bacterium, advantageously belonging to the genera Beggiatoa, Vitreoscilla, Flexithrix or Leucothrix, formulated into a cosmetically/pharmaceutically acceptable vehicle, diluent or carrier therefor.
