The present invention concerns the use of a rice protein hydrolysate in order to pigment the skin and skin appendages. Thus, it is possible to intensify the normal pigmentation of the skin without sunlight. Preferred areas of applications are repigmentation of white patches of the skin, repigmentation of white patches of the skin as a consequence of pityriasis or due to the use of dermocorticoids; acceleration and intensification of the tanning process, stimulation of the constitutive photoprotection and improvement of the phototype, prevention of skin photocarcinogenesis. Advantageously, the rice protein hydrolysate comprises peptides of which at least 50 % have a molecular mass in the range of between 300 and 3,500 Da.
La présente invention concerne l'utilisation d'un hydrolysat de protéines de riz pour pigmenter la peau et les phanères. Il est ainsi possible d'intensifier la pigmentation normale de la peau sans soleil. Les applications préferées sont la repigmentation des tâches blanches cutanées, la repigmentation des tâches blanches cutanées consécutives à un pityriasis ou dues à l'utilisation de dermo-corticoïdes, l'accélération et l'intensification du bronzage, la stimulation de la photoprotection constitutive et le renforcement du phototype, la prévent ion de la photocancérogénèse cutanée. L'hydrolysat de protéines de riz comprend avantageusement des peptides dont au moins 50% ont une masse moléculaire comprise entre 300 et 3 500 Da.
