POLYGLUTAMIC ACID (PGA)

Polyglutamic acid is a biopolymer—that is, a e macromolecule naturally produced by living organisms (plants, algae, animals, etc.). In cosmetics, it is generally obtained from soybeans fermented with a “good bacterium” called Bacillus subtilis.

It was first discovered around the 1930s and extracted from marine jellyfish, in which it helps retain water and prevent dehydration accelerated by saltwater. It is also found in large quantities in nattō, a traditional Japanese food made from fermented soybeans.

Although polyglutamic acid is not naturally present in the human body, it is indeed of natural origin, and our skin can fully benefit from its moisturizing properties.

A true defense against dehydration, polyglutamic acid offers numerous benefits for the skin.

✔ Moisturizing: It keeps the skin intensely hydrated by preventing water from evaporating.

✔ Protective: It forms a layer on the skin’s surface, acting as a barrier against external aggressors.

✔ Plumping: It helps smooth out wrinkles and fine lines and strengthen the skin’s elasticity.

✔ Revitalizing: It helps limit the loss of hyaluronic acid while enhancing its action, and also boosts the production of certain anti-aging molecules naturally present in the body.

Polyglutamic acid is suitable for all skin types (oily, combination, acne-prone, normal, dry)—even the most sensitive and reactive skin—and for all skin tones, from the darkest to the lightest.

Its moisturizing properties make it particularly beneficial for dry, dehydrated, and dull skin.
