Melibiose
What is Melibiose?
Melibiose is a naturally occurring disaccharide composed of one glucose molecule linked to one galactose molecule, derived from the partial hydrolysis of raffinose found in plants like legumes and beets. In cosmetics, it belongs to the category of humectants and skin conditioning agents, commonly incorporated into moisturizers, serums, and cleansers. Functionally, it works by attracting and retaining water molecules from the environment and deeper skin layers into the upper skin barrier, promoting a smoother, more supple texture. This mechanism supports the skin's natural moisture balance without relying on oils or emollients. As a simple sugar with low molecular weight, it penetrates superficially to enhance hydration efficiency in formulations designed for daily use.
