Polyglutamic Acid

Polyglutamic acid (PGA) is a rising star in the skincare world. This miracle ingredient, often compared to hyaluronic acid, offers exceptional hydrating properties, in addition to a range of other skin benefits. Let's discover together why this active ingredient is gaining popularity and how it can transform your skincare routine.

What is polyglutamic acid?

Polyglutamic acid is an amino acid polymer naturally derived from soy fermentation. Its unique feature lies in its impressive ability to trap water and form a protective film on the skin's surface. This film acts as a barrier that prevents moisture loss while providing an incomparably soft feel.

Intense hydration for all skin types

What makes polyglutamic acid so remarkable is that it is suitable for all skin types, whether dry, oily, sensitive, or combination. It acts as a super hydrator thanks to its ability to retain up to 5000 times its weight in water, even surpassing hyaluronic acid, which can retain up to 1000 times its weight. This makes it a valuable ally for skin lacking hydration.

A matter of molecular weights

The molecular size of polyglutamic acid plays a key role in its performance. Unlike hyaluronic acid, which exists in different molecular weights, PGA forms a protective film on the skin's surface. This film acts as a hydration reservoir that gradually releases water and enhances skin protection.

The benefits of polyglutamic acid for the skin

  1. Skin hydration: Thanks to its exceptional ability to trap water, PGA improves skin elasticity and softness.
  2. Stimulates production: It also helps to stimulate the natural production of NMF (Natural Moisturizing Factors) in the skin.
  3. Eye contour: Due to its hydrating properties, it is perfect for the eye contour, a delicate area often prone to dehydration and fine lines.
  4. Forms a protective film: By acting as a barrier, it reduces water evaporation and strengthens the skin's barrier function.

How to integrate polyglutamic acid into your routine?

Polyglutamic acid is often included in products such as hydrating serums and face creams. Here are some tips to maximize its effects:

  • Morning and evening: Apply a serum or cream containing PGA after cleansing your skin, ideally on slightly damp skin to seal in moisture.
  • Complementary with hyaluronic acid: Although it is more effective at retaining water, hyaluronic acid and PGA work very well together to provide multi-layer hydration.

An exceptional ingredient for radiant skin

In summary, polyglutamic acid is a revolutionary active ingredient capable of transforming skin hydration thanks to its unique hydrating properties. Whether it's to improve skin texture, hydrate the eye contour, or create a protective film, this acid is a must for anyone who wants radiant and healthy skin. Try it today in a hydrating serum, and your skin will thank you!
