Ce que c\u2019est<\/h2>\n

Le collag\u00e8ne est la principale prot\u00e9ine de la peau, des tendons, des cartilages et des os. Le collag\u00e8ne marin est extrait de la peau, des \u00e9cailles ou des ar\u00eates de poissons. L\u2019hydrolyse le d\u00e9coupe, \u00e0 l\u2019aide d\u2019enzymes, en petits fragments appel\u00e9s peptides, qui se dissolvent dans l\u2019eau et se dig\u00e8rent plus facilement que le collag\u00e8ne entier.<\/p>\n

Une m\u00e9ta-analyse de 19 essais<\/a>, men\u00e9s chez 1 125 personnes de 20 \u00e0 70 ans, en grande majorit\u00e9 des femmes, a trouv\u00e9 que le collag\u00e8ne hydrolys\u00e9, toutes origines confondues, am\u00e9liorait l\u2019hydratation et l\u2019\u00e9lasticit\u00e9 de la peau et r\u00e9duisait les rides par rapport au placebo.<\/p>\n

Chez 50 femmes de 45 \u00e0 60 ans, 10 g de collag\u00e8ne hydrolys\u00e9 de poisson par jour pendant 12 semaines ont fait baisser le score de rides de 35 % par rapport au d\u00e9part, et les rides du c\u00f4t\u00e9 droit du visage de 24 % de plus que sous placebo (Evans et al., 2021<\/a>).
