Science
Mechanism of Action
Melibiose works by leveraging its excellent water-binding efficiency, forming a protective layer on the skin that effectively minimizes transepidermal water loss and prevents dehydration, thereby promoting a smooth and healthy appearance. Beyond hydration, it directly influences keratinocyte biology, which is a key mechanism in diminishing skin pigmentation. Additionally, its role in firming skin is attributed to its ability to reduce cellular breakdown, particularly beneficial for dry skin.

No data in the research indicates that melibiose is prone to dusting or presents related red flags in formulations.
The Formula
Formulation
Stability
Melibiose can crystallize as a hydrate from aqueous or hydroalcoholic solutions. However, its amorphous form exhibits notable stability and slow molecular mobility within studied water content ranges, making it an advantageous lyoprotectant in formulations. Optimal stability in cosmetic products is achieved when the formulation's pH is precisely adjusted between 4.5 and 5.5, typically using citric acid solution.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has thoroughly assessed melibiose, alongside other mono- and disaccharides, concluding its safety for use in cosmetic applications. As a common dietary sugar with established oral safety, the primary focus of its safety evaluation for topical use addresses potential dermal toxicity, including irritation and sensitization. No maximum concentration limit was deemed necessary.
