摘要:
The present invention is directed to a method of treating skin and scalp comprising applying on the scalp or skin a composition comprising a scalp care active selected from the group consisting of 2-Pyridinol-N-oxide, a pyrithione or a polyvalent metal salt of pyrithione, one or more iron chelator having an A log P value of greater than or equal to 0.4 and mixtures therein; exposing the scalp and skin to electromagnetic radiation having wavelength from about 350 nm to about 500 nm and power from about about 0.1 mWatts/cm2 to about 1000 mWatts/cm2 and for a time period from about 2 seconds to about 5 minutes; wherein the antimicrobial treatment results in reduction of fungal growth as measured by the Fungal Growth Sensitivity Test of at least 50% compared to the dark sample.
摘要:
A method for making a skin care composition by identifying connections between cosmetic agents and genes associated with one or more skin aging conditions. The method includes accessing a plurality of instances and at least one skin aging gene expression signature, comparing the at least one skin aging gene expression signature to the plurality of the instances, assigning a connectivity score to each instance based on the comparison and incorporating the cosmetic agent into a skin care composition when the connectivity score of the instance associated with the cosmetic agent has a negative correlation.
摘要:
The present invention is directed to a method for treating a hair disorder in a human or animal in need thereof, involving topically applying to the human or animal an effective amount of at least one 6-substituted 2-pyridinol N-oxide compound, a tautomer, or a cosmetically acceptable salt thereof wherein a hair count is increased by at least 0.5 hairs/cm2 and/or an increase the number of anagen hairs and maintain the number of telogen hairs when compared to a baseline and/or vehicle.
摘要:
Methods and systems for constructing a gene expression signature representative of a number of biological conditions, systems and methods for determining functional relationships between a skin-active agent and skin conditions of interest, and methods and systems for identifying skin-active agents with broad spectrum activity are provided.
摘要:
A system for identifying connections between a cosmetic agent and at least one gene associated with a skin aging condition. The system includes a computer readable medium having stored thereon a plurality of instances and a skin aging gene expression signature. Each instance comprises an ordered list of identifiers representing a plurality of differentially expressed genes generated as a result of contact between the cosmetic agent and a human fibroblast cell or a human keratinocyte cell. The computing device includes computer-readable instructions for accessing the plurality of instances and the skin aging gene expression signature stored on the computer readable medium, comparing each of the instances to the skin aging gene expression signature, and assigning a connectivity score to each of the instances based on the comparison.

摘要:
Provided are methods and systems for determining functional relationships between a cosmetic agent and a hair biology condition of interest. Also provided are methods and systems for identifying cosmetic agents that affect a hair biology condition, as well as the use of agents identified by such methods and systems for the preparation of cosmetic compositions, personal care products, or both.
