Cassia Angustifolia Seed Polysaccharide

Snapshot

Plant-derived polysaccharide from Cassia angustifolia seeds that mimics hyaluronic acid, helping hydrate, smooth, and protect skin.

 

What It Is

Cassia angustifolia seed polysaccharide is a natural galactomannan extracted from the seeds of the Senna plant (Cassia angustifolia). It is often marketed as a botanical alternative to hyaluronic acid for skin hydration and conditioning.

Where It Comes From

Native to India and Egypt, Cassia angustifolia (also called Senna) produces seeds rich in polysaccharides. These are processed into a water-binding polymer used in topical skincare formulations.

Key Nutrients & Compounds

Composed primarily of galactose and mannose units, the polysaccharide forms a film on the skin’s surface that binds water and provides immediate hydration. It also contains small amounts of flavonoids and glycosides naturally present in the seed.

Health Benefits

  • Hydration – Provides moisture retention similar to hyaluronic acid by binding water to the skin.
  • Skin Smoothing – Improves suppleness, reduces the appearance of fine lines, and enhances texture.
  • Protective Film – Creates a lightweight layer that shields skin from environmental stressors.
  • Soothing Effects – May calm irritation and support barrier repair.

Recommended Dosage

There is no oral dosage—this compound is for topical use in cosmetics and skin care. In formulations, concentrations typically range from 0.1–1% depending on the product type (serums, creams, gels).

How To Use It

Look for serums, moisturizers, or masks listing “Cassia Angustifolia Seed Polysaccharide” as an active. Apply to cleansed skin once or twice daily, ideally layered before an occlusive moisturizer to lock in hydration.

Who Should Use It

Anyone seeking enhanced hydration, especially those with dry, dehydrated, or sensitive skin. It is also suitable for individuals wanting a plant-based alternative to hyaluronic acid.

Possible Interactions or Cautions

Generally considered safe for topical use with low risk of irritation. Avoid if allergic to legumes (rare). Patch testing is recommended for very sensitive skin. Not intended for ingestion.

Final Thoughts

Cassia angustifolia seed polysaccharide is a gentle, plant-based hydrator that rivals hyaluronic acid for moisture retention and skin smoothing—an excellent botanical upgrade for modern skincare.
