Polyglutamic acid (PGA) is obtained from soybeans that have undergone a fermentation process. It is a competitor to the well-known hyaluronic acid and has a powerful anti-aging effect on the skin - it fights wrinkles and hyperpigmentation, accelerates the process of skin regeneration, moisturizes and increases the elasticity of the epidermis. The complete instructions for the use of this care ingredient were compiled together with dermatologist, cosmetologist and plastic surgeon Madina Bayramukova.
Polyglutamine VS hyaluron
It is believed that polyglutamic acid attracts and binds five times more water molecules than hyaluronic acid, therefore it has a much more intense moisturizing effect. Moreover, PG, unlike other similar substances, is able to penetrate into the deep layers of the skin, even being in the composition of cosmetics. Polyglutamic acid works in two directions at once: it not only deeply moisturizes the skin, but also forms a film on its surface that prevents moisture loss. To achieve greater effectiveness, polyglutamic acid can be used in combination with hyaluronic acid.
The mechanism of action of PG is aimed at blocking hyaluronidase - the very enzyme that destroys our own hyaluronic acid in the dermis, thereby interfering with the synthesis of collagen and elastin.
Who is polyglutamic acid suitable for?
Polyglutamic acid is suitable for all skin types, especially dry and dehydrated skin. But it is important to remember that it can cause an allergic reaction when exposed to sensitive skin. Therefore, an allergy test should be done before using PG products.
How to use it?
Polyglutamic acid is a new addition to the cosmetic market and is worth looking for in serums and other skin moisturizers. PG is a powerful anti-age component that should not be applied on an ongoing basis, but in courses. The skin periodically needs a rest from strong acids, so you shouldn't deprive it of the opportunity to “work” on its own. Do not forget also that any miraculous serum works only in tandem with the usual care products - moisturizing or nourishing.
It is unacceptable to use serums instead of face creams. So you run the risk of getting the opposite effect: instead of deep moisturizing of the skin, you will encounter increased dryness and sensitivity of the epidermis.
Apply serums according to the correct algorithm: first, a complex skin cleansing, including a toning stage to restore PH-balance, then apply a serum and finally - a regular cream for general skin care (read also: "What is a serum and how to use it correctly") …
