What it is
Fructose is a monosaccharide naturally present in fruits and honey. In formulas it acts as a humectant, helping draw water into the upper layers of the skin and contributing to a conditioned feel. It is often included as part of a sugar or natural moisturizing factor blend in sunscreens and other skincare products.
Safety & warnings
Fructose is a well-tolerated, water-soluble sugar and is not associated with irritation, sensitization, or comedogenicity in cosmetic use.
Origin & sourcing
Natural; a simple sugar found in fruits, honey, and many plants, typically sourced from plant material.
