Product Description

Gamma-poly-glutamic acid (γ-PGA) is a natural, multi-functional, biodegradable biopolymer produced from L-glutamic acid through a fermentation process with a Bacillus subtilis. PGA is a water-soluble homo-polyamide consisting of D- and L-glutamic acid monomers connected by amide linkages between α-amino and γ-carboxyl groups. It has high water absorbability and moisturizing effect with multiple functionalities including Long-lasting moisturizing effect and inhibition on Melanin Biosynthesis.

• Everyone can benefit from extra hydration and a smooth complexion. But if you're struggling with dry or dehydrated skin, this ingredient is even more essential within your routine. "Working as a humectant, a polyglutamic serum will seal in moisture leaving your skin plump and hydrated.

• While they're both effective hydrators, polyglutamic acid has better performance and additional benefits to moisturize that hyaluronic acid does not have.Depending on the source, polyglutamic acid holds 4,000-5,000 times its weight in water. Hyaluronic acid is usually cited as 1,000 times its weight in water.

• There's no need to worry about separating exfoliants or retinol products when using polyglutamic acid. "Polyglutamic acid can be paired with almost any ingredient. If you're someone who struggles with dry skin, patchy skin, polyglutamic acid and hyaluronic acid can save the day. When used together, both active ingredients deliver twice as much hydration, each working together to penetrate and lock in moisture. For further recommendations
