Hyaluronic acid has been popular as a cosmetic ingredient for years. For some time now, however, dermatologists have been leaning towards another acid that can work up to 10 times better. It will help not only moisturize, but also nourish and revitalize the skin.
Better than hyaluronic acid? Dermatologists are thrilled
Polyglutamic acid is a peptide, meaning it consists of a group of glutamic acid molecules. It is usually produced synthetically for cosmetic purposes, although it can also be produced in the natural fermentation process of soy. It is worth knowing that this acid increases the solubility of the substance in water.
What's more, as a by-product of the fermentation of Bactilis subtilis bacteria, it is completely harmless to the natural environment. When it comes to cosmetics, polyglutamic acid is referred to by many as the “new, better hyaluronic acid.” All because its moisturizing power is, according to some, even 10 times greater.
At first, however, polyglutamic acid was considered solely as a carrier of active substances into the skin, thanks to its ability to penetrate the epidermis. However, it did not take long to find out that it can quickly moisturize the skin on its own.
This is because it creates a “barrier” on its surface, which retains moisture inside the tissue. Thanks to this, the application of polyglutamic acid allows you to maintain the appropriate level of water in the skin even in unfavorable external conditions. This means that dry air, wind or even air conditioning will not be a threat to it.
How does polyglutamic acid work? Not only does it moisturize
Not long ago, when talking about hydration, hyaluronic acid came to mind. This is because one molecule of it can bind up to 250 molecules of water. However, polyglutamic acid beats it hands down. It turns out that it can retain up to 4,000 times more water than its own weight in the skin. It is estimated to be 4 to 10 times stronger than hyaluronic acid.
Polyglutamic acid works as a humectant, a substance that attracts and retains moisture in the skin. In short, this means that it not only prevents water loss, but also creates a protective layer, helps maintain an optimal level of moisture, prevents dryness and eliminates the feeling of tight skin.
It is also worth adding that it has a soothing effect. It helps reduce irritation and inflammation and supports wound healing. Thanks to it, the skin will be smooth, firm and moisturized. In addition, it also has the ability to fill fine lines and wrinkles. It acts as a tightening substance.
Polyglutamic acid can be found primarily in moisturizing cosmetics dedicated to all skin types. It is usually present in a concentration of 0.3 to 2.5 percent.
Interestingly, using polyglutamic acid does not mean that we have to give up hyaluronic acid. Dermatologists advise using both, starting with hyaluronic acid and ending with polyglutamic acid.
