Products Description
Sodium hyaluronate, also known as hyaluronic acid, is a natural substance widely present in the human body, especially abundant in areas such as the skin and joints. It has various positive effects on the skin, mainly including strong moisturizing, deep hydration, and promoting cell regeneration.
Sodium hyaluronate is widely used in the field of beauty, and attention should be paid to possible allergic reactions or capillary dilation during use. Therefore, a skin test should be conducted before use to ensure that there are no adverse reactions before continuing to use.

Applications
Moisturizing Series Products
It is an essential raw material for moisturizing lotions, toners, and moisturizing creams. Its strong hydrophilicity can quickly replenish skin moisture, lock in water for a long time, improve skin dryness, roughness and tightness, and keep the skin soft, tender and hydrated for a long time. It is especially suitable for dry skin care products, effectively relieving dry and peeling problems.
Anti-Aging & Repair Series Products
It is widely used in anti-aging serums, eye creams, and repair masks. It can penetrate into the deep layer of the skin, stimulate the synthesis of collagen and elastin, enhance the skin's elasticity and toughness, reduce the appearance of fine lines, wrinkles and dry lines, and delay skin aging. At the same time, it can repair the damaged skin barrier caused by external stimuli (such as sun exposure, dry environment, and improper skin care), soothe sensitive skin, and improve skin tolerance.
Frequently Asked Questions
What is the difference between Sodium Hyaluronate and Hyaluronic Acid?
-
Sodium Hyaluronate is the salt form of Hyaluronic Acid. It has smaller molecular weight, better water solubility, higher stability and easier to be absorbed by skin, which is more suitable for cosmetic formulations.
Is this Sodium Hyaluronate suitable for sensitive skin?
-
Yes. Our cosmetic grade Sodium Hyaluronate is high purity, non-toxic, non-irritating, no preservatives and no allergens. It is safe for sensitive skin, dry skin and oily skin.
What molecular weight do you provide? How to choose?
-
We provide high, medium and low molecular weight Sodium Hyaluronate. High MW for surface moisturizing and film forming; Medium MW for moisturizing and elasticity; Low MW for deep penetration and repair. We can recommend according to your formula needs.
Can you provide free samples and COA?
-
Yes. We can provide 10-20g free samples for testing. COA, MSDS, specification sheet and other certification documents can be provided together with the goods or sent in advance.
