Skin Care Ingredients and Cosmetic Claims Substantiation
Could you recommend resources to learn more about cosmetic claim substantiation (in vitro and in vivo) for skin care ingredients? I work at an ingredients manufacturer and want to learn more about how I can best provide substantiation for skin care ingredients (actives & functional raw materials) via in vitro & in vivo methods. I welcome any recommendations for books, articles, experts, testing houses, courses, advice, etc.
Thanks so much for your help!
