If you haven’t heard of polyglutamic acid before, you aren’t behind the times. This ultra-hydrating skin plumper has been largely overlooked as its moisture-binding sister molecule, hyaluronic acid, has achieved cult status.
It’s time to give polyglutamic acid’s skin-flooding superpowers the recognition they deserve. Join us as we dive deep into the science behind polyglutamic acid’s powerful skincare benefits and explain how to use it in your routine.
What is Polyglutamic Acid?
Polyglutamic acid is a fermented ingredient formed when multiple molecules of glutamic acid are linked together via the fermentation process to form a natural, biodegradable polymer. Polyglutamic acid (PGA) is also a peptide that can easily penetrate the top layers of skin to support collagen production.
Polyglutamic acid attracts water from the surrounding environment and pulls it into your skin. As a polymer, it also forms a protective skin to keep it evaporating, locking moisture into your skin.
Why is PGA Used in Skincare?
As we age, our skin begins losing its natural hydrator, hyaluronic acid, as it’s broken down by an enzyme called hyaluronidase. Polyglutamic acid serums – such as our Copper Peptide Rapid Plumping Serum – inhibit the action of hyaluronidase, preserving hyaluronic acid in the skin while also flooding the skin with additional moisture
6 Skincare Benefits of Polyglutamic Acid:
Polyglutamic Acid vs. Hyaluronic Acid
Hyaluronic acid (HA) achieved its well-deserved cult status as a non-irritating hydrator for its ability to bind with water and pull it into the skin.
While PGA also binds with water, its larger molecular size enables it to hold five times more moisture than HA. Those bigger molecules also weigh more, allowing it to dramatically smooth the top layers of the skin.
PGA’s final party trick: it seals in the moisture it attracts, flooding the skin with hydration and holding it there for a lasting plumping effect.
All of these powerful anti-aging benefits aside, we like to think of polyglutamic acid and hyaluronic acid as friends, not competitors. These two ingredients work beautifully when combined to double down on skin-smoothing hydration.
About Our Polyglutamic Acid Serum
Our award-winning Copper Peptide Rapid Plumping Serum combines the ultra-hydrating power of PGA with hyaluronic acid and ectoin to flood skin with moisture and seal it in for continuous, lasting hydration. Meanwhile copper peptides support collagen and elastin for bouncy skin and boost production of hyaluronic acid for even more hydration in a unique symbiosis of ingredients for ultimate results.
In consumer trials, 97 percent of participants reported a visible firmness in smoothness and elasticity. Even better, 100 percent noticed visible improvement in fine lines and wrinkles after 4 weeks of use.
How to Use Polyglutamic Acid in Your Skincare Routine
Polyglutamic acid’s moisture-binding abilities make it an ideal ingredient for people with dry, dehydrated, or stressed-out skin. It also works harmoniously with skincare actives including retinol and vitamin C.
We recommend applying a polyglutamic acid serum such as our Copper Peptide Rapid Plumping Serum while skin is still damp from toning. This allows the PGA to bind with the water molecules sitting on top of your skin, pulling them into your epidermis and boosting PGA’s hydrating, plumping effect.
