Method for regulating the condition of mammalian skin comprising the steps of applying a first personal care composition to an area of skin where regulation is desired, wherein the first personal care composition comprises at least one skin care active selected from the group consisting of niacinamide, salicylic acid, peptides, N-acetyl glucosamine, panthenol, butylated hydroxytoluene, N-acyl amino acid compounds, hexamidine, green tea, ascorbyl glucoside, hexanediol, pentanediol, a skin lightening agent, a heat shock protein potentiator, and mixtures thereof, and delivering energy to the area of skin by contacting the skin with an energy delivery device for a treatment period of at least 2½ minutes, wherein the energy delivery device comprises a skin-contacting surface that is controllably heatable to a temperature of from 37° C. to 50° C.

The present invention relates to the use of certain resorcinol derivatives as skin lightening agents.

The present invention comprises a structured premix or “delivery vehicle” composition designed as a carrier to enhance the benefit (e.g., via enhanced deposition or other mechanism) of a separate hydrophobic benefit agent(s) (for example, perfumes, skin lightening agents, etc.), from personal product compositions (e.g., liquid and bar cleansers, creams, emulsions, hair composition, deodorant etc.). When the structured benefit agent composition is separately prepared and combined with the personal product composition (preferably while structured, premix composition is still in molten or liquid state), the personal product composition with structured benefit agent carrier provides enhanced deposition of the structured benefit agent and enhanced effect of the separate hydrophobic benefit agent(s) in or on the carrier or in the presence of structured benefit agent carrier.

Cosmetic compositions and methods, particularly for skin lightening, using N-acylbenzothiazolone compound and derivatives of general formula I as skin lightening agents alone or in combination with other skin benefit agents and together with a cosmetic vehicle:

Where R represents a hydrogen atom, C₁-C₄ acyl group, or C₁-C₄ alkyl group. Preferably, the compound is 3-propionylbenzothiazol-2-one, i.e. where R in the formula I is C₁ alkyl group.

A system for identifying connections between perturbagens and genes associated with a skin hyperpigmentation condition. The system includes a computer readable medium having a plurality of instances stored thereon, and a skin hyperpigmentation-relevant gene expression signature. Each instance includes an instance list of rank-ordered identifiers of differentially expressed genes, and the hyperpigmentation-relevant gene expression signature includes a gene expression signature list of identifiers representing differentially expressed genes associated with a hyperpigmentation condition or differentially expressed genes associated with a benchmark skin-lightening agent. The system also includes a programmable computer with computer-readable instructions that allow the computer to accessing the instances and a hyperpigmentation-relevant gene expression signature stored on the computer readable medium, comparing the hyperpigmentation-relevant gene expression signature to the plurality of the instances, and/or assigning a connectivity score to each of the plurality of instances.
