The harder it is to pronounce, the more effective the ingredient is. This isn’t actually a statement, but for polyglutamic acid (as well as bakuchiol, tranexamic acid, and squalane) it’s true.
Although polyglutamic acid is somewhat new to the world of skin care, it answers a lot of questions we've been thinking about for years, like "How to hydrate skin without feeling dry after seconds" and "How best to create hydration Moisturize and maintain natural moisture.” appearance."
It's also included in our new Moisture Maker Hydrating Hyaluronic Acid Serum. With the help of dermatologist Dr. Factor, we've taken an in-depth look at polyglutamic acid (and the best ways to use it) below.
What is polyglutamic acid? “Polyglutamic acid is a water-soluble peptide (a long-chain amino acid, a building block of proteins like collagen and elastin),” says Dr. factor.
Specifically: "Polyglutamic acid was originally used in wound healing and is made from chains of amino acids [called] glutamate. Unlike some moisturizers that penetrate the skin, polyglutamic acid is a larger molecule that sits on top."
You can also add polyglutamic acid to the long list of humectants we often find in moisturizers and oils, such as: B. Hyaluronic acid, glycerin, bamboo extract (found in our hydrating toner), Lactic acid and snow fungus.
Like other humectants, polyglutamic acid absorbs moisture from the air, providing moisture both on the surface and underneath the skin.
Benefits of polyglutamic acid. Polyglutamic acid is best known for its moisturizing properties, specifically its ability to hold 4,000 times its weight in water (that's four times more than hyaluronic acid, the most famous moisturizing ingredient on the market today).
"The main benefit of polyglutamic acid and other humectants is to keep the skin moisturized by drawing moisture from the air into the upper layers of the skin," agrees Dr. Factors to. “A 2015 study found that polyglutamic acid increases the body’s production of the following natural moisturizing factors:
carboxylic acid, lactic acid, pyrrolidone, and urocanic acid. They are all naturally produced by the body and work by locking in moisture. Keep your skin hydrated.”
Because of these moisturizing properties, polyglutamic acid is an ideal ingredient to add to your daily routine if you want to strengthen or repair your skin's moisture barrier, which has its own benefits (softer texture, less irritation, and fewer breakouts— — to name just one) very few). a couple).
Since it's slowly absorbed into the skin, it also provides a radiant, dewy glow. Polyglutamic acid can "add brightness, like a natural highlighter," agrees Dr. Factor in.
That's why we include this peptide in Luminizing Glow Drops, to enhance skin's natural glow and gently blur pores.
Use polyglutamic acid if any of the following are on your list of skin goals: Skin is hydrated and soft. Reinforced moisture barrier. Hydrating, elastic texture. Fine lines and pores are less visible
How and when to use polyglutamic acid? According to Dr. Polyglutamic acid, it has similar properties to other moisturizers such as hyaluronic acid, which means it is best suited for dry and dehydrated skin, but can benefit all skin types.
It's gentle enough for even sensitive skin to use without fear of irritation or redness, and it's also safe to use during pregnancy.
As a peptide, it coordinates well with all other ingredients. Moisture Maker combines polyglutamic acid and hyaluronic acid, two moisturizers for anyone who wants plumper, more hydrated skin that attracts and retains moisture over time.
It's especially useful in combination with retinol, as its moisturizing properties can counteract the drying side effects of vitamin A derivatives. (Or you can use our gentle Retinol Serum and Retinol Body Lotion, which contain naturally non-drying encapsulated retinol.)
To get the most out of polyglutamic acid, use daily. Since it does not make skin more sensitive to sunlight, it can be used in the morning and/or evening.
