Humectant hydration across molecular weights
The sodium salt of hyaluronic acid. This isn't a cosmetic distinction: sodium hyaluronate has a smaller, more stable molecular structure than raw hyaluronic acid, which is why it's the form actually used in formulations rather than HA itself.
Hyaluronic acid is a humectant that can hold up to 1,000x its weight in water. Molecular weight determines where it works:
High molecular weight
Sits on the surface, forms a hydrating film, reduces water loss.
Low molecular weight
Penetrates into the epidermis, hydrates at a deeper level.
Multi-weight formulations
Combine both, hydrating at the surface and slightly deeper simultaneously.
The right active means nothing if it can't reach the right layer. Explore the patented delivery platform behind the formulations, or browse the full ingredient library.
