Science
Mechanism of Action
Also known as Pro-Xylane, this ingredient functions primarily by stimulating the skin's intrinsic production of glycosaminoglycans (GAGs), such as hyaluronic acid, within the extracellular matrix. This action significantly boosts moisture retention, leading to improved skin hydration, plumpness, and refined texture. Concurrently, it promotes the synthesis of multiple collagen types (I, III, IV, and VII), which are essential for maintaining skin's structural integrity, firmness, and elasticity between the epidermis and dermis. Furthermore, it supports growth factor modulation, reinforces the extracellular matrix, and strengthens the skin's natural barrier function, contributing to enhanced skin repair.

The Formula
Formulation
Stability
This ingredient is water-soluble and maintains stability within a pH range of 3.5 to 7.0. For optimal long-term storage, it should be refrigerated, shielded from direct sunlight and heat, and kept in a tightly sealed container. While it can tolerate temperatures up to 80°C during the water-phase mixing, it is generally advised to keep temperatures below 40°C for overall stability.
Safety
Safety Profile
Specific safety evaluations by major regulatory bodies such as CIR, SCCS, or FDA are not currently documented. Although many sources suggest it is generally non-irritating and well-tolerated by various skin types, including sensitive skin, one report indicates a potential for irritation, particularly when co-formulated with other problematic ingredients, which could lead to inflammation or dryness.
