Key Benefits

Endogenous Hyaluronic Acid Support

Supports endogenous hyaluronic acid production to help improve skin hydration and moisture retention.

Barrier Repair & TEWL Support

Skin Smoothness & Resilience

Supports the skin's natural self-repair processes and promotes smoother, more resilient-looking skin.

Mechanism of Action

The peptide complex supports complementary cosmetic pathways associated with endogenous hydration, barrier repair and skin self-repair. By promoting hyaluronic acid synthesis and helping reinforce moisture retention, it supports a stronger skin barrier, reduced water loss and a smoother, better-hydrated appearance.
