It’s so hard to keep track of the newest skin care superstars. As soon as you make a splurge purchase for a “magic” new product, another one comes along that promises to knock that old-school stuff off your bathroom shelf. Polyglutamic Acid (PGA) may prove to be a true product.
First, if you’re jumping in on the “food as skin care” trend, it could be an interesting ingredient, since PGA is a peptide naturally derived from the bacillus bacteria in nattōAlso known as Japanese fermented soy beans. “It’s created when multiple glutamic acids link together,” dermatologist Seemal R. DesaiHuffPost was told by a professor and clinical assistant in dermatology at University of Texas Southwestern Medical Center. “It can be extracted from the soybeans or synthesized in a lab.”
It might also be a good option if your skin is preparing for winter. “It is indeed a very powerful hydrator,” dermatologist Pearl E. GrimesIt was. “Reportedly, it can absorb moisture up to 4,000 to 5,000 times its own weight, as compared to hyaluronic acid, which typically absorbs up to 1,000 times its own weight. The following have been some studies in recent years showing its efficacy in moisturizing and hydrating the skin, and there even are some studies suggesting its potential for speeding up the skin’s healing process.”
All things Wound Care to Super Moisturizer
This ingredient is used for skin treatment since many years. “It’s traditionally been used in wound healing, but recently its popularity has increased as a skin care ingredient,” dermatologist Heather Woolery-LloydHuffPost. Why? It’s simple. “If your skin is thirsty, PGA quenches the thirst,” Desai said. “It helps attract and maintain moisture and hydration in the skin.” And thanks to all that hard work, it may indirectly reduce the appearance of fine lines and wrinkles by replacing moisture in the cells,” he said.
Are You Ready for PGA?
If the term “acid” is worrisome, never fear. “The acid groups are not very strong, so the irritation potential is a lot lower than you’d expect from an ingredient with the word ‘acid’ in its name,” said Michelle WongDr. chemistry, founder of Lab Muffin Beauty Science
PGA can be tolerated by all skin types, including oily, dry, and combination skin. “It’s thought to be good on all skin types,” Desai said. He suggested, however, that you seek advice from your board-certified dermatologist before you try the product.
Experts recommend that you be cautious and take it slow. “While generally well tolerated, PGA could potentially be irritating or cause an allergic reaction in sensitive skin types,” Grimes said. “It’s important to try a product containing PGA in a small amount on the skin to test it out and wait 24 hours to see if there is any adverse reaction.”
Hyaluronic Acid can be teamed up with it
Thinking back to your overflowing product shelf, it’s good to know that this product plays well with others.
“It can actually be used alongside hyaluronic acid,” said Joshua ZeichnerA dermatologist, and an associate professor at Mount Sinai Hospital’s School of Dermatology in New York. “My suggestion would be to apply hyaluronic serum first, then layer the polyglutamic acid product on top of it.”
Next, there’s the issue of prepping your skin so it gets the most benefit from the ingredient. “As a powerful humectant, it needs water to effectively do its job,” Grimes said. “It should be properly layered on top of cleansed, damp skin, and if the product you’re using does not already have an occlusive ingredient in it, it should be sealed or locked in with an occlusive moisturizing product on top.” (Occlusive means a product designed to prevent water loss.)
How to Choose the Right PGA for You
Many experts believe that the verdict is still out on which products are the most efficient. “It’s still relatively new, so I don’t have any personal favorites yet,” Woolery-Lloyd said. However, experts who spoke with us recommended that you carefully read the label before purchasing. “Check to make sure the product has been scientifically tested and studied and has minimal preservatives,” Desai said. “Look at the ingredient profile and see if PGA is listed, and then look at the other ingredients and make sure those also work with your skin and your own skin care goals.”
