Use of an active principle originating from flax in a composition intended to reinforce the barrier function of the skin and to protect the skin and the appendages against external aggressions
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.
