Polyglutamic Acid is a naturally occurring biopolymer derived from fermented soybeans or other plant sources. It is a water-soluble, biodegradable, and biocompatible compound with excellent hydrating properties.

In cosmetic formulations, Polyglutamic Acid is highly valued for its superior moisture-retaining abilities. It has the capability to hold more than 500 times its weight in water, making it an outstanding humectant for the skin.

When applied topically, Polyglutamic Acid forms a protective film on the skin's surface, reducing water loss and promoting a soft, smooth, and plump complexion. It is well-tolerated by the skin and suitable for all skin types, including sensitive skin.


Hydrating Skincare: Polyglutamic Acid is commonly used in hydrating skincare products, including serums, moisturizers, and masks, to provide intense and long-lasting hydration, improve skin texture, and reduce dryness and flakiness.

Anti-Aging Formulations: The compound is included in anti-aging products to address fine lines and wrinkles, as well as to support overall skin health and resilience.

Primer and Makeup Base: Polyglutamic Acid can be found in makeup primers and bases to create a smooth canvas for makeup application and enhance makeup longevity.
