1. A method for treating a skin or skin appendage condition in a subject, the method comprising a step of administering to the subject a composition comprising hydrolysed yeast proteins,
wherein the hydrolysed yeast proteins comprise at least 40% of yeast proteins with a molecular weight ranging from 1 to 5 kDa and are obtained by:
submitting Saccharomyces cerevisiae yeast cells to a thermal treatment carried out for 1 to 3 hours at between 70° C. and 90° C.,separating yeast hulls after thermal treatment of yeast, andsubmitting the yeast hulls to exogenous enzymatic hydrolysis with at least one peptidase for at least 18 hours at a temperature of between 45° C. and 65° C. to produce a reaction mixture comprising hydrolyzed yeast proteins, andseparating the hydrolyzed yeast proteins from the reaction mixture, wherein treating a skin or skin appendage condition is selected from the group consisting of: treating dry skin, reducing sebum secretion, treating skin aging, promoting skin firmness, treating dandruff, promoting hair brightness and softness, and any combination thereof. |
