What Is Glucose?
Glucose is the most abundant monosaccharide and the primary energy source for all living cells. In skincare, glucose functions as a humectant (water-binding), an osmolyte (protecting cells from dehydration), and a metabolic substrate for skin cell energy production. It is a natural component of the skin's Natural Moisturizing Factor (NMF) and contributes to stratum corneum hydration. Often used in post-procedure and wound-care formulations for cellular support.
