A small, naturally-occurring peptide and one of the most-studied in skin science, researched for over four decades. We use it at a meaningful, stable concentration consistent with published cosmetic literature.

A humectant that holds many times its weight in water. We use a low-molecular-weight grade selected for skin comfort and absorption, not just surface plumping.

Plant-derived humectants. They draw moisture into the skin and help the formula feel smooth on application — no tightness, no residue.

A modern, plant-friendly thickener. Gives The Renewal its weightless, fluid texture without polymers that pill on the skin.

A solvent that helps actives stay evenly distributed in the formula. Improves the feel of application.

A widely-used, well-tolerated preservative system. Keeps the formula clean from first press to last without parabens, formaldehyde-releasers, or sensitizers.

A naturally-derived chelator. Stabilizes the copper peptide so it stays active throughout the life of the bottle.
