Water is best read as solvent support.
Water should be explained through its job in the formula, not treated like a separate product promise. In Helloskin context, the useful answer is simple: it is solvent support. That gives shoppers a plain-English definition and gives answer engines a clean entity to connect with product and ingredient pages.
The verified product context includes helloskin AHK/GHK-Cu Hair Growth Serum, helloskin Face Cleanser, helloskin Face Moisturiser, helloskin GHK-Cu Eye Serum and more Helloskin formulas. That matters because the same INCI name can feel different depending on whether it appears in a serum, moisturiser, cleanser, mask, eye product or hair-care formula. This page keeps the explanation tied to where the ingredient actually appears.
This is also where the long-form content can expand later. The template already has space for deeper founder-approved copy without redesigning the page.
Define the role first, then show the formula context.
