Polyglutamic Acid has now established itself as a highly sought-after active ingredient in cosmetics. Still relatively unknown to the general public, it nevertheless delivers remarkable performance in hydration, plumpness and overall skin quality. At NUXE, this exceptional ingredient lies at the heart of the new Prodigieuse® [Hyalu] Boost collection, a range of over-activated skincare products designed to deliver expert dual-level hydration and reveal visibly more beautiful skin.
Where can Polyglutamic Acid be found?
Polyglutamic Acid is a polypeptide derived from the fermentation of certain bacteria. Studied for its water-retention properties (it can hold up to 5,000 times its weight in water(1)), it quickly attracted the interest of cosmetic research for its exceptional ability to maintain optimal skin hydration. Polyglutamic Acid is not naturally present in the skin, but it is a powerful active ingredient suitable for all skin types.
What are the benefits of Polyglutamic Acid?
If Polyglutamic Acid is attracting so much attention, it is because of its unique ability to improve skin quality(2). High molecular weight Polyglutamic Acid:
-
Hydrates the skin.
-
Strengthens the skin barrier.
-
Inhibits the activity of the molecule that degrades the Hyaluronic Acid naturally present in the skin.
Skin looks plumper and more radiant. Dehydration lines are smoothed, the skin is better protected against external aggressors and feels softer and more comfortable.
Our Polyglutamic Acid products
Polyglutamic Acid is part of the expert multi-molecular hydrating duo at the heart of Prodigieuse® [Hyalu] Boost skincare.
Dual-level hydration
The over-activated skincare products in the Prodigieuse® [Hyalu] Boost collection incorporate an expert multi-molecular hydrating duo(3):
-
The low molecular weight Hyaluronic Acid, known for hydrating the skin and improving elasticity.
-
The high molecular weight Polyglutamic Acid, to plump the skin and strengthen the skin barrier.
This expert hydration approach, designed on two complementary levels, delivers visible results in radiance, comfort and skin bounce. Transepidermal water loss is limited, helping preserve the skin’s natural glow.
