Naturally occurring Hyaluronic Acid molecule is too large and cannot penetrate the skin easily.
Sodium Hyaluronate is the salt form of Hyaluronic Acid. When in its salt form, the molecule has a much smaller molecular weight than it's hydrolyzed cousin and therefore; is able to penetrate deeper into the skin. Sodium Hyaluronate is also more stable and is less likely to oxidise. Sodium hyaluronate has incredible hydrating benefits that address a number of skin concerns caused by a lack of moisture in the skin.
Combats skin dryness: As a humectant, it pulls in water from the air and helps to retain moisture to keep your skin hydrated and flake-free.
Repairs a compromised moisture barrier: It's essential for restoring and maintaining a healthy barrier to prevent transepidermal water loss (TEWL), which can lead to inflammatory conditions.1
Improves signs of aging: Sodium hyaluronate works to replace lost moisture and hyaluronic acid naturally found in the skin that lessens with age.2 This added hydration, in turn, may smooth texture created by fine lines and wrinkles.
Improves breakout-prone skin: According to Shah, it could help your acne by rebalancing the skin if you are overly drying it with harsh exfoliants, cleansers, and treatments. It's also generally considered to be non-comedogenic, which means it won't clog pores.
Plumps: Sodium hyaluronate provides structure and volume and can create temporary but instantaneous plumpness in the skin.
Leaves a non-greasy glow: It has a lightweight feel and imparts a dewy finish without leaving a thick, greasy residue.
Helps eczema: Since the ingredient is so gentle, it's safe to use on sensitive skin and can be beneficial for severely dry skin types.
Restores skin post-procedure: Weinstein and Shah both recommend the use of sodium hyaluronate to hydrate after in-office procedures, such as lasers or micro-needling, which make the skin vulnerable.
So the hyaluronic acid is a major component in our body. Sodium hyaluronate is a derivative of hyaluronic acid. The difference between sodium hyaluronate and hyaluronic acid is that the sodium hyaluronate is the sodium salt of hyaluronic acid whereas the hyaluronic acid is glycosaminoglycan common in human connective tissues.
