Move over, hyaluronic acid: the newest powerhouse moisturizing ingredient flooding the skincare market is polyglutamic acid (PGA). it's going to technically be an acid, but it's nothing like exfoliating peels that use ingredients like salicylic or glycollic acid that we use to slough off dead skin. In fact, polyglutamic acid has been found to carry up to five ,000 times its own weight in water, fourfold that of mucopolysaccharide , meaning the buzzy new ingredient packs a serious hydrating punch.
Quickly becoming a breakout ingredient in skincare, PGA is extremely versatile: "It’s water soluble, it’s anionic, it’s biodegradable, it’s nontoxic, it’s edible," says Flora Kim, M.D., a board-certified dermatologist in Dallas. "All of those different qualities has made it successfully utilized in multiple different industries." Here's everything you would like to understand about the new skin thirst-quencher:
What exactly is polyglutamic acid?
Polyglutamic acid may be a natural polymer (often produced by fermentation of bacteria) that was originally utilized in wound healing. Unlike some moisture boosters that penetrate skin, polyglutamic acid may be a larger molecule that sits on top, which helps skin glow and increases luminosity (like a natural highlighter!). “It both hydrates skin and makes it look more plump,” says Dr. Kim.
What are the advantages of polyglutamic acid?
There's still tons to find out about the ingredient, but here are a number of the items that polyglutamic acid shines at:
Hydration. a bit like its cousin mucopolysaccharide , polyglutamic acid is additionally a moisturizing superstar. As a humectant, it retains moisture from water with “excellent water- binding properties and long-lasting moisture retention capacity,” Dr. Kim explains. “This can indirectly improve skin’s elasticity.”
Wound healing. Before polyglutamic acid ever made its way into your cold cream , it had been getting used within the medical realm, primarily for wounds and burns. Many skincare advancements actually start with wound care, since it uses many of an equivalent properties as skincare, says Dr. Kim: "When you’re healing wounds you've got to supply tons of hydration and moisture, [so it] only is sensible that it starts thereupon ."
Anti-aging. Since hydration helps improve the elasticity of skin, polyglutamic acid can help to scale back wrinkles. consider a raisin vs. a grape: they appear much different, but the sole difference is hydration. "A raisin is all shriveled up and it's got these wrinkles, but if you only add water and moisture thereto , it plumps up. That’s a method of thinking [about] what polyglutamic acid potentially can do." Dr. Kim says that there also are a couple of reports that polyglutamic acid has anti-radical activity which will aid in anti-aging, but these need further research.
Are there any side effects to polyglutamic acid?
Since polyglutamic acid may be a gentle and hydrating ingredient, it's pretty universal. "In general, anyone should be fine, but in fact there could always be an exceptions, so you only need to hear your skin," Dr. Kim explains. One thing to stay in mind: While some products will only have polyglutamic acid as a lively ingredient, some contain other actives which will be harsh on certain skin types, so always read the ingredient list.

How often should polyglutamic acid be used?
This depends on your skin, but the great thing is that you simply can't really overdo it on pure polyglutamic acid, so no got to worry about how often you employ it, such as you might with other acids like AHAs or BHAs.
If you're during a "dry environment and you’re skin’s dry, you almost certainly got to apply it quite frequently and perhaps a better quantity," Dr. Kim says. On the opposite hand, if you're during a humid environment and/or you've got oilier skin, you'll not got to apply it as often — but it's good for a hydration boost as required on all skin types and every one environments.
What results do you have to expect from using polyglutamic acid?
Because of its humectant properties, you'll expect your skin to seem and feel more moisturized and plump with reduced fine lines and wrinkles, says Dr. Kim. Since PGA sits on top of your skin rather than penetrating at heart , Dr. Kim says it is a good way to urge a coveted "glass skin" look — a K-beauty phenomenon where skin looks clear, dewy, smooth, and glass-like.
How am i able to fit polyglutamic acid into my skincare routine?
As long because the product you're using doesn't contain other active ingredients already (check the label!), polyglutamic acid are often added into any skincare routine, and there is no got to exercise caution when using it with products like vitamin C , retinol, or niacinimide.
What polyglutamic acid products are best?
Polyglutamic acid is usually found in serums, but it is also in everything from eye creams to sheet masks. For the simplest benefits, search for polyglutamic acid within the top half the ingredients lists of topical skincare products that are left on skin instead of rinsed off, like moisturizers and serums. This way, you'll make sure that you're getting the very best concentration of polyglutamic acid and therefore the most benefits.
