Abstract: A cosmetic or pharmaceutical, and in particular a dermatological one, including, in physiologically adapted medium, an active principle capable of activating cytochrome C. This active principle may be composed of polypeptides or of peptides, used alone or in association with at least one other active principle. This active principle may also be included in a cosmetic composition intended to stimulate the functions of the mitochondria and to increase the cellular energy level. The active principle be also be used in a cosmetic-treatment procedure intended to protect the skin and the appendages from external aggressions and to combat cutaneous aging.

Abstract: The present invention concerns the use, in a cosmetic composition, of an effective quantity of active principle originating from flax (genus Linum) to activate cytochrome c and to stimulate the functions of the mitochondria. The active principle originates from the hydrolysis of flax proteins and contains principally polypeptides or peptides. It can be used alone or in association with at least one other active principle. The invention further relates to a method of cosmetic treatment intended to protect the skin and the appendages from external aggressions and to combat against cutaneous ageing.

Abstract: The present invention concerns the use, in a cosmetic composition, of an effective quantity of active principle originating from flax (genus Linum) to reinforce the barrier function of the skin and to protect the skin and the appendages against external aggressions. The active principle originates from the hydrolysis of flax proteins and contains principally polypeptides or peptides. The invention likewise relates to the use, in a cosmetic composition, of a peptidic hydrolysate of flax as active principle capable of activating HMG-CoA reductase. The invention likewise relates to the use of a peptidic hydrolysate of flax as active principle capable of activating transglutaminase. The active principle can likewise be used to prepare pharmaceutical compositions intended to prevent or combat against the pathologies linked to alterations to the barrier function, such as certain hypersensitivies, irritations of the skin and reactive skins, or atopic dermatitis.

Abstract: A cosmetic or pharmaceutical composition, and particularly dermatological composition, comprising, in a physiologically adapted medium, as active principle, polypeptides or peptides, and methods of administering a composition capable of increasing cell energy and to protect the skin from oxidative damage. Also, a cosmetic treatment procedure aimed at protecting the skin and the skin appendages from external aggressions and to combat skin aging.

Abstract: The present invention has as an aim a cosmetic and/or dermatological and/or pharmaceutical composition comprising, as an active ingredient, at least a peptide of sequence X1-Y-Phe-Thr-X2-Ala-Thr-Z-Ile-X3-Leu-X4-Phe-Leu-X5 (SEQ ID NO: 1); wherein: X1, X2, X3, X4, X5=Arg, Lys, His; Y=Asp, Glu; Z=Asn, Gln, or one of its fragment containing from 4 to 7 amino acids, and the motif Phe-Leu. The invention also relates to a method for preventing or treating skin against the manifestations of cutaneous aging.

Abstract: The invention concerns the use, as active principle, in or for preparing a composition, of an efficient amount of at least one extract of cotton honeydew, the extract or the composition being designed for care of keratinous substrates. The invention also concerns a cosmetic and/or pharmaceutical composition containing said extract, and a method for cosmetic treatment of the skin using said cotton honeydew extract or the composition containing same.

Abstract: A cosmetic and/or dermatological and/or pharmaceutical composition includes, as the active ingredient, at least one peptide with sequence X1-Y-Phe-Thr-X2-Ala-Thr-Z-Ile-X3-Leu-X4-Phe-Leu-X5; wherein: X1, X2, X3, X4, X5=Arg, Lys, His; Y=Asp, Glu; Z=Asn, Gln. The invention also relates to the use of said composition in order to treat, inter alia, the signs of cutaneous ageing. Moreover, the invention relates to the cosmetic skin treatment method using the peptide.
