Abstract: Substituted and unsubstituted flavone or isoflavone glycoside derivatives of the formula [A1-C(?O)O]m—[X—O-Z]—[O—C(?O)-A2]n, wherein [X—O-Z] represents a flavone or isoflavone glycoside structure, particularly a naringin residue, X is a flavone or isoflavone corresponding to formula (IIa) or formula (IIb): wherein the flavone or isoflavone residue is substituted one or more times and/or reduced one or more times; Z represents a mono-, di- or polysaccharide, which is acetally-bound at the benzopyran group to X and ester-substituted by —O—C(?O)-A2; [A1-C(?O)] is an acyl group on the flavone or isoflavone; A1 and A2 independently, represent a polyunsaturated C15-26 alkenyl group containing at least four isolated and/or at least two conjugated double bonds, or an arylaliphatic radical with 1-to-4 methylene groups between the ester group and the aromatic ring; [C(?O)A2] is an acyl group; n is an integer other than 0; m is an integer, including 0; and R1, R2 and R are hydroxyl groups or hydrogen atoms.

Abstract: The invention relates to a method for determining hair cycle markers in vitro, test kits and biochips which are used to determine hair cycle markers and to the use of proteins, mRNA molecules, proteins or fragments thereof as hair cycle markers. The invention also relates to a test method which is used to detect the effectiveness of cosmetic and pharmaceutical active ingredients which influence the hair cycle, in addition to a screening method which is used to identify cosmetic or pharmaceutical active ingredients which influence the hair cycle and to a method for the production of a cosmetic and pharmaceutical preparation which influences the hair cycle.

Abstract: The invention relates to a method for determining the homeostasis of hairy skin in vitro, to test kits and biochips for determining markers of hairy skin, in addition to the use of proteins, mRNA molecules or fragments thereof as markers of hairy skin. The invention also relates to a test method for detecting the effectiveness of cosmetic or pharmaceutical active substances for treating hairy skin in addition to a screening method for identifying cosmetic or pharmaceutical active substances for treating hairy skin and to a method for producing a cosmetic or pharmaceutical preparation for treating hairy skin.

Abstract: The invention relates to a skin/hair equivalent, more particularly a hair model with reconstructed papillae (pseudopapillae; PP) in a reconstructed dermis (pseudodermis; PD), to its production and to its use, more particularly for medical/pharmaceutical purposes and for application in the cosmetics industry.

Abstract: Novel topical cosmetic and pharmaceutical compositions containing apple core extracts, and novel uses of apple core extracts in topical cosmetic or pharmaceutical compositions.

Abstract: A method of using DNA repair enzymes in topical cosmetic or pharmaceutical compositions for the prevention of the ageing of human skin. In particular, the method prevents ageing effects caused by light. The method prevents the degradation of collagen within connective tissue, specifically within the dermis of the skin.

Abstract: The invention relates to flavone and isoflavone glycoside derivatives of general formula (I): [A1-C(═O)O]m—[X—O-Z]-[O—C(═O)-A2]n (I), wherein [X—O-Z] represents a flavone or isoflavone glycoside structure, wherein X represents a flavone or isoflavone parent substance of formula (IIa) or (IIb), said (iso)flavone parent substance being mono- or multisubstituted and/or mono- or multireduced (hydrogenated), wherein Z (sugar) represents a mono-, di- or polysaccharide which is acetally bonded to the radical X and is ester-substituted with A2 n-times, [A1-C(═O)] representing an acyl radical on the flavone or isoflavone parent substance, wherein A1 and A2, independently of each other, represent a polyunsaturated C15-C25-alkenyl radical with at least 4 isolated and/or at least 2 conjugated double bonds or an arylaliphatic radical with 1-4 methylene groups between the ester group and the aromatic ring, wherein [C(═O)A2&rs
