Is Polyglutamic Acid Moisturizer Better Than Hyaluronic Acid

Reading Is Polyglutamic Acid Moisturizer Better Than Hyaluronic Acid 5 minutes

Polyglutamic acid moisturizer is a new cosmetics ingredient in market now. It has very strong moisturizing. People often ask, is this much better than hyaluronic acid powder?

Polyglutamic acid is 4x greater moisture retaining benefits than HA. However, the effects of the two ingredients are not exactly the same.

Polyglutamic Acid and Hyaluronic Acid are two skin care ingredients that differ in chemical structure, mechanism of action, and application.

What Is Polyglutamic Acid

Polyglutamic acid is usually a polymer with the chemical formula ((C4H8NO3)x). It is a water-soluble polyamino acid produced by microbial fermentation.

In cosmetics, polyglutamic acid is used as a natural moisturizing factor. It can form a protective film to lock in skin moisture. , thus achieving effects such as moisturizing and whitening.

What Is Hyaluronic Acid

Hyaluronic acid is a natural polysaccharide commonly found in the connective tissue of the skin and eyeballs. It can absorb dozens of times its own weight in water to maintain skin elasticity and moisture. It is a widely used natural moisturizing factor.

What’s the Difference Between Polyglutamic Acid and Hyaluronic Acid

Chemical structure

Polyglutamic acid

It is a polypeptide compound composed of multiple aminoglutamic acid units. Its molecular structure has multiple carboxyl groups (COOH) and amine groups (NH2), so it is a polypeptide chain in chemical structure.

Hyaluronic acid is a glycosaminoglycan composed of N-acetylglucosamine and D-glucuronic acid linked by β-1,3 and β-1,4 glycosidic bonds. Its molecular structure has repeating galactose and glucuronic acid units.


Polyglutamic acid is mainly used as a moisturizer and skin barrier repair agent. It can absorb water molecules and enhance the skin barrier function, thereby increases the skin's moisture content and moisturizing degree.

Hyaluronic acid is also a moisturizer, but its mechanism of action is slightly different from polyglutamic acid. It attracts and holds large amounts of water molecules, forming a hydrogel-like network structure that increases the skin's moisture content and improves skin elasticity.


There are significant functional differences between Polyglutamic acid moisturizer (PGA) and hyaluronic acid (HA), although they both have moisturizing effects. Here are the main functional differences between them.


1, Moisturizing

PGA has stronger moisturizing ability than hyaluronic acid and can absorb and retain more moisture. Its moisturizing effect is said to be 4 times that of hyaluronic acid.

2, Skin Elasticity

PGA can enhance skin elasticity, help reduce fine lines and wrinkles, and improve skin firmness.

Antioxidant and anti-aging

It has antioxidant effects and can help slow down the aging process of the skin.

Inhibit melanin

PGA can inhibit the production of melanin and has the effect of whitening and brightening skin.

Repair skin barrier

PGA helps repair and strengthen the skin barrier, making the skin healthier and suitable for sensitive skin.

Hyaluronic Acid Functions

Intense moisturizing

HA is known for its excellent moisturizing ability, which can absorb and lock 1000 times its own weight in moisture, deeply moisturizing the skin.

Applications of different molecular weights

High molecular weight HA: Forms a moisturizing film on the skin surface to prevent moisture loss.

Low molecular weight HA: It can penetrate deeper into the skin and provide deep moisturizing effect.

Promotes skin healing

Hyaluronic acid in wound healing and tissue regeneration and is often used as a filler in the medical and cosmetic fields.

Comfortable use: Hyaluronic acid powder is light in texture, non-greasy, and suitable for all skin types, especially oily and combination skin.

Broad compatibility: HA can be used well with other skin care ingredients to enhance the overall skin care effect.


Moisturizing effect

Although both have moisturizing effects, Polyglutamic acid moisturizer has a relatively stronger moisturizing ability and helps maintain skin elasticity.

Anti-aging and whitening

PGA has a more obvious effect in anti-aging and whitening.

Skin repair: PGA helps repair the skin barrier and is suitable for sensitive skin; Hyaluronic Acid is effective in promoting skin healing and tissue regeneration.

Feeling of use

HA has a light texture and is suitable for all skin types, especially oily and combination skin, while PGA may be thicker.

How to Choose Polyglutamic Acid and Hyaluronic acid Powder

Which ingredient is better to choose depends mainly on your skin needs:

If you need stronger moisturizing effect and other additional functions (such as whitening, increasing elasticity, etc.), you can choose products containing polyglutamic acid moisturizer.

If you pay more attention to the lightweight feel and safety, and want sustained and stable moisturizing effect, hyaluronic acid may be more suitable for you.

Of course, the best option may be a product that combines both ingredients, which takes advantage of the best of both and provides a more comprehensive skin care effect.
