Polyglutamic Acid

Description

Polyglutamic Acid (PGA) is a powerful humectant and hydrating agent gaining popularity in advanced skincare formulations. This water-soluble polymer, derived from fermented soybeans, consists of long chains of glutamic acid molecules. PGA boasts a remarkable ability to retain moisture, reportedly holding up to 5,000 times its weight in water, surpassing the hydration capacity of hyaluronic acid.

In skincare applications, PGA forms a protective film on the skin's surface, reducing transepidermal water loss and enhancing overall hydration. This ingredient is particularly effective in addressing dehydrated, dull, and aging skin concerns. PGA's large molecular size allows it to work primarily on the skin's surface, complementing smaller molecular hydrators that penetrate deeper layers.

Studies indicate that PGA may stimulate the skin's natural moisturizing factors and promote hyaluronic acid production. Additionally, it exhibits antioxidant properties, potentially offering protection against environmental stressors. PGA is generally well-tolerated across various skin types and can be incorporated into serums, moisturizers, and masks. Its compatibility with other active ingredients makes it a versatile component in multi-functional skincare formulations, contributing to improved skin texture, plumpness, and overall appearance.
