Polyglutamic Acid FAQs
Common questions about this ingredient in skincare.
What is Polyglutamic Acid?
It is a fermentation-derived amino-acid polymer used as a humectant and film-forming moisturizer in skincare.
Is it an exfoliating acid?
No. Despite the word “acid,” Polyglutamic Acid is not used like glycolic or salicylic acid and does not exfoliate skin.
How is it different from hyaluronic acid?
Both are humectant polymers, but they have different chemical structures and sensory properties. They can be used together rather than treated as interchangeable.
When should I apply it?
Use a product containing it on clean skin according to directions, typically before heavier creams or oils. Applying moisturizer over it can help seal in hydration.
Can sensitive skin use it?
It is generally considered a gentle hydration ingredient, though reactions can occur to any finished formula. Patch-test if your skin is highly reactive.
Does it permanently fill wrinkles?
No. By improving surface hydration, it may temporarily soften the look of dehydration lines, but it does not permanently alter wrinkles.
