Hydrolyzed Sodium Hyaluronate
What is Hydrolyzed Sodium Hyaluronate?
Hydrolyzed Sodium Hyaluronate is the sodium salt form of hyaluronic acid that has undergone hydrolysis, breaking its long polysaccharide chains into shorter fragments. Hyaluronic acid is a naturally occurring glycosaminoglycan found in human connective tissues. In cosmetics, it is typically produced through bacterial fermentation for purity and vegan suitability. This ingredient functions primarily as a humectant and skin-conditioning agent in formulations like serums, moisturizers, and essences. Its low molecular weight—often below 50 kDa—enables superior penetration through the skin's outer layers compared to non-hydrolyzed versions. Once absorbed, it binds water molecules effectively, promoting moisture retention within skin cells and the extracellular matrix, which supports overall skin hydration dynamics. It is stable across a range of pH levels and compatible with most cosmetic actives.
Benefits
Enhances skin hydration by attracting water to the surface and deeper layers
Supports a smoother skin texture through moisture balance
Aids in maintaining skin's natural moisture barrier
Who It's For
A quick guide for who this ingredient may suit (and who should be cautious).
| Who May Benefit | Who Should Avoid |
|---|---|
| Individuals with dehydrated or dry skin | Those with known hypersensitivity to hyaluronic acid derivatives |
| Those seeking improved skin plumpness | Individuals prone to hyaluronidase-related reactions |
| People with normal to combination skin types wanting added hydration | People using products with potential for ingredient interactions |
Safety Notes
- Rated low hazard by safety assessments for cosmetic use
- Non-comedogenic, unlikely to clog pores
Frequently Asked Questions about Hydrolyzed Sodium Hyaluronate
What makes hydrolyzed sodium hyaluronate different from sodium hyaluronate?
Hydrolysis reduces molecular size, allowing deeper skin penetration while both act as humectants.
Is it suitable for sensitive skin?
It generally shows low irritation in safety evaluations, but patch test if concerned.
Where is it sourced from?
Commonly derived from bacterial fermentation processes for cosmetic-grade purity.
