Humectant
What it is
A powerful humectant made from fermented soybeans. It is a polymer of the amino acid glutamic acid and is known for its exceptional water-binding capacity.
How it works
Polyglutamic Acid forms a hydrophilic film on the skin's surface that draws in and holds a large amount of water, reportedly even more than hyaluronic acid. This action provides intense surface hydration and helps to reduce the appearance of fine lines.
Benefits
- Provides powerful surface hydration.
- Forms a smooth, moisturizing film on the skin.
- Enhances skin's elasticity.
- May help to inhibit the enzyme that breaks down natural hyaluronic acid in the skin.
