Raffinose Good Humectant Hydration Raffinose at a glance Trisaccharide composed of galactose, glucose, and fructose Found in plants and vegetables like cabbage, beans and broccoli Attracts and binds moisture to skin Hydrates and balances, giving skin a plump, healthy look Raffinose description Raffinose is a high molecular weight trisaccharide (a type of oligosaccharide or complex sugar) found in plants that’s utilized in cosmetics for its hydration benefits. It’s made up of galactose, glucose and fructose. Its large molecule size keeps it from penetrating past skin’s surface. Like many other saccharides, raffinose’s skin hydration benefits come from its humectant properties, drawing water to skin and then assisting skin in holding onto that moisture in a balanced fashion. Through this process, raffinose helps hydrate, resulting in plump, healthy-looking skin. Research suggests that raffinose, when applied topically, can help visibly improve skin that’s prone to psoriasis and eczema. However, further research is needed on raffinose’s abilities to earn a strong recommendation for these conditions. At the time of writing this entry, usage levels for raffinose in cosmetics have not been established. However, it is not known to pose a safety or irritation risk for skin.
