Polyglutamic Acid (PGA) is a water-soluble peptide derived from fermented soybeans, known for its exceptional hydration and skin-enhancing properties.

It is often compared to hyaluronic acid but can hold up to four times more moisture, making it a powerful addition to skincare products.

Its ability to lock in hydration and improve skin elasticity makes it ideal for anti-aging and moisturizing formulations.

Benefits of Polyglutamic Acid in Skincare:

Superior Hydration:
Retains up to 5,000 times its weight in water, delivering intense moisture to the skin.

Locks in Moisture:
Forms a protective film on the skin’s surface to prevent water loss, keeping the skin hydrated for longer.

Improves Skin Elasticity:
Promotes plump and supple skin by enhancing the skin's natural elasticity.

Enhances Skin Texture:
Smooths the appearance of fine lines and wrinkles, providing a youthful glow.

Boosts Active Ingredient Absorption:
Improves the penetration of other active ingredients in your skincare routine.

Non-Irritating:
Gentle and suitable for all skin types, including sensitive and acne-prone skin.

How to Use Polyglutamic Acid in DIY Skincare:
