How does the dual hyaluronic acid system in this night cream work to improve skin hydration?

The formula relies on a dual hyaluronic acid system, which means it contains two distinct forms of sodium hyaluronate designed to work at different depths within the skin. One form has a higher molecular weight, allowing it to remain primarily on the skin's surface. This top layer acts as a moisture reservoir, actively attracting and holding water to prevent immediate evaporation. The second form features a lower molecular weight, which enables it to penetrate more evenly into the upper layers of the epidermis. This deeper distribution helps create a fuller, more uniformly hydrated appearance from within. Together, these two mechanisms address dryness from multiple angles: the surface form provides immediate relief from tightness and dryness, while the deeper form supports long-term suppleness. This combined approach can help make fine dehydration lines appear less noticeable by plumping the skin structure with retained moisture. For best results, this hydration strategy is most effective when applied to clean, slightly damp skin, allowing the hyaluronic acid to bind with available water molecules effectively before the oils in the cream seal everything in overnight.
