Ingredient analysis and how the ad lines read

What is this product?
Where the brand overreaches is the wording, because low molecular weight, packed full and deep into skin is more than a single hyaluronate at a disclosed 2,700ppm, or 0.27 percent, with no molecular weight given, can carry.
What makes it different?
Disclosing a concrete 2,700ppm (0.27 percent) on its one hyaluronate is unusual transparency next to rivals that either stack several hyaluronates with no amounts at all or publish only a fraction of theirs. The base is water, three glycols and glycerin carrying beta-glucan, betaine, panthenol, sorbitol, acetyl glucosamine, glucuronic acid, allantoin and tocopherol, so the hydration is broad even where it is not deep. It also comes as a 238ml can refill alongside the 200ml and 500ml bottles, and that 238ml format is rare in this category.
