Zinc PCA is the zinc salt of pyrrolidone carboxylic acid (PCA), one of the documented constituents of skin's natural moisturising factor, supported by published research on the zinc-ion class in human skin1. Sodium Hyaluronate is a glycosaminoglycan naturally present in skin that helps it retain moisture2.

A twenty four hour rhythm
THE SKIN KEEPS TIME
Skin is not the same at midnight as it is at nine in the morning. Across a single day its temperature, its acidity and the moisture it loses to the air each move on a rhythm of their own. Morning and night are not two routines. They are one, kept in time.
