Sodium hyaluronate is a derivative of hyaluronic acid, a naturally occurring polysaccharide found in connective tissues such as cartilage. It is a popular cosmetic ingredient known for its ability to hydrate and plump the skin. Here are some details, positive and negative aspects, and ingredients or materials related to sodium hyaluronate in skin care:
Details:
- Sodium hyaluronate is a humectant, which means that it attracts moisture.
- It is more stable than hyaluronic acid and less prone to oxidation, which is why it often appears in skin care products.
- Sodium hyaluronate can help the skin look youthful and supple.
- It can easily and deeply penetrate the skin to help it retain moisture for increased firmness and suppleness, resulting in a revitalized appearance.
Positive aspects:
- Sodium hyaluronate is hydrophilic, meaning it easily mixes with water. When applied topically, it attracts moisture in skin cells. This reduces dryness and flaking by increasing skin hydration.
- It can help replace the skin’s natural hyaluronic acid content, which diminishes with age, exposure to UV radiation, and various other environmental factors that lead to gradual moisture loss.
- Sodium hyaluronate can increase the final product’s stability and reduce the probability of oxidization.
Negative aspects:
- Sodium hyaluronate is listed in the PETAs Caring Consumer guide as derived from animal sources.
- EWG VERIFIED products cannot contain this ingredient without adequate substantiation.
Ingredients or materials:
- Sodium hyaluronate is the sodium salt form of hyaluronic acid.
- It can be extracted from hyaluronic acid and used separately.
- Sodium hyaluronate is derived from HA, so it may be listed as “hyaluronic acid (as sodium hyaluronate)” on skin care labels.
Overall, sodium hyaluronate is a popular ingredient in skin care products due to its hydrating and plumping effects on the skin. It is a humectant that attracts moisture and can easily penetrate the skin to help it retain moisture for increased firmness and suppleness. However, it is important to note that some products containing sodium hyaluronate may be derived from animal sources, and EWG VERIFIED products cannot contain this ingredient without adequate substantiation.
