Abstract: The invention relates to a cosmetic composition for bleaching the skin, which includes a) at least one oily plant extract from the Glycyrrhiza genus and b) at least one ascorbic acid ester. The invention further relates to the cosmetic, nontherapeutic use of the cosmetic composition according to the invention to treat excessive pigmentation, pigmentation disorders, age spots, and/or post-inflammatory hyperpigmentation of the skin, and to a method for producing a cosmetic skin-bleaching composition in the form of an O/W or a W/O emulsion, wherein an oily extract from licorice roots is dissolved in the water phase by the addition of an ascorbic acid ester.

Abstract: The present disclosure concerns an in-vitro method for the identification and analysis of proteins with a stem cell function, in which initially, at least one three-dimensional sweat gland equivalent with from about 500 to about 500000 sweat gland cells as well as a diameter of from about 100 to about 6000 ?m is provided and subsequently, proteins with a stem cell function in this equivalent are identified and analyzed. Preferably, in a further step c) of the method, the influence of test substances on the proteins previously identified in step b) is investigated. Because the three-dimensional sweat gland equivalents used in step a) comprise differently differentiated cells and emulate the in-vivo situation well, the measured data obtained with the in-vitro method as contemplated herein can readily be applied to the in-vivo situation.

Abstract: The present disclosure relates to an in-vitro method for identifying and analyzing secretion proteins, in which a three-dimensional sweat gland equivalent having from about 500 to about 500,000 sweat gland cells and a diameter of from about 100 to about 6,000 ?m is firstly provided and then any secretion proteins present in this equivalent are infected and analyzed. In a further method step c) the influence of test substances on the proteins identified previously in step b) is examined. Since the three-dimensional sweat gland equivalents used in step a) comprise differently differentiated cells and portray the in-vivo situation well, the measurement data obtained with the in-vitro method as contemplated herein can be transferred well to the in-vivo situation.

Abstract: The present disclosure relates to an in-vitro method for identifying and analyzing ion channels and/or water channels and/or receptors of signal transduction, in which a three-dimensional sweat gland equivalent having from about 500 to about 500,000 sweat gland cells and a diameter of from about 100 to about 6,000 ?m is firstly provided and then any ion channels and/or water channels and/or receptors of signal transduction present in this equivalent are infected and analysed. In a further method step c) the influence of test substances on the proteins identified previously in step b) is examined.

Abstract: Specific oligopeptides, and a cosmetic agents that include such oligopeptides, are used for stimulating the natural pigmentation process in cutaneous appendages, in particular human hair and hair follicles.

Abstract: Surprisingly, it has now been found that, when a hair care agent including at least one casein hydrolysate is applied, the hair growth itself and thus also the structure, elasticity, strength, resistance, and shine of the keratin fiber are significantly improved. Furthermore, is has surprisingly been found that the compositions according to the invention are suitable for triggering the release of growth factors and for strengthening and thickening the hair by stimulating the proliferation of the hair keratinocytes. The stimulation of the keratinocytes of the outer root sheath, which are partly responsible for the formation of the hair shaft, occurs by means of the growth factors HGF and KGF. Effects such as the “overconditioning” of the hair are avoided by means of the biologically based hair thickening. The hair grows more intensely from the root on and with a larger diameter, so this effect is particularly long-lasting.

The invention further relates to the cosmetic, nontherapeutic use of the cosmetic composition according to the invention to treat excessive pigmentation, pigmentation disorders, age spots, and/or post-inflammatory hyperpigmentation of the skin, and to a method for producing a cosmetic skin-bleaching composition in the form of an O/W or a W/O emulsion, wherein an oily extract from licorice roots is dissolved in the water phase by the addition of an ascorbic acid ester.

Abstract: Cosmetic composition comprising at least one compound from advanced glycation end products (‘AGEs’) and/or precursors thereof as an agent for skin treatment, especially for protection and/or care of the skin. The present invention further provides a cosmetic composition comprising at least one compound from the group of the AGEs and/or precursors thereof, wherein the AGEs are prepared by reacting sugars with the amino acids lysine and/or arginine.

Abstract: The present invention is a hair treatment agent comprising a combination of dihydroquercetin and/or a dihydroquercetin derivative with at least one amino acid. A preferred hair treatment agent comprises a combination of dihydroquercetin (taxifolin) with a six-amino acid mixture consisting of taurine, proline, valine, arginine, lysine, and glycine. The inventive hair treatment agent positively influences the natural pigmentation process of skin and skin appendages, such as for example, stimulating melanogenesis and pigmentation of hair, preventing and reducing the graying of hair, and repigmenting gray hair.

Abstract: A method for positively influencing the natural pigmentation process of skin or appendages thereof includes topically contacting the skin or appendages thereof with a combination of carnitine and/or a derivative thereof with dihydroquercetin and/or a derivative thereof.

Abstract: A method for influencing the natural pigmentation process of skin or appendages thereof, includes the step of topically contacting the skin or appendages thereof with at least one nucleic acid containing at least 55% guanine nucleotide.
