Difference between hyaluronic acid and sodium hyaluronate in skin creams? Is a hyaluronic acid skin cream effective?

Hello, I am 24 years old, but I am noticing dehydration lines starting to form. I have been researching various skin care products, and Cerave seems to have many key ingredients, one being hyaluronic acid. However, when researching many other skin care products, sodium hyaluronate seems to more widely used (as opposed to hyaluronic acid), as it is has a smaller molecular size and can easily be absorbed in to the skin, as opposed to hyaluronic acid which many say cannot be absorbed topically.
