Depends on Source
How we decideIt depends on the source. Hyaluronic acid can come from rooster combs or microbial fermentation, and the ingredient name does not distinguish the route.
Hyaluronic acid is a long sugar polymer that binds water. Sodium hyaluronate is its sodium salt, so both names can raise the same sourcing question.
These flags describe sourcing. They are not an allergen assessment, and a vegan label is not a free-from claim. If you have an allergy, read the allergen declaration on the pack.

Hyaluronan
Commercial hyaluronic acid can be extracted from animal tissues such as rooster combs or produced by microbial fermentation.
Facial serums, moisturizers, masks, eye products and dermal fillers.
Hyaluronic acid with a supplier statement confirming microbial fermentation and animal-free processing.
Ask whether the material is extracted from rooster combs or made by microbial fermentation. For fermented material, a strict check can also ask whether the growth medium and processing aids are animal-free. Sodium hyaluronate is a related salt and carries the same source question.
