I was very interested to read the recent Refinery 29 article on Polyglutamic Acid and see a number of products which are now being produced using this peptide. It is particularly interesting as Polyglutamic Acid has a high moisturisation capability that is far superior to hyaluronic acid and collagen.
The benefit of Polyglutamic Acid is that it keeps skin hydrated for much longer. It stabilises naturally occurring hyaluronic acid in the skin and improves NMF function (Natural Moisturising Factor) that is responsible for the barrier (protective coat) on your epidermis. A compromised skin barrier can be responsible for a multitude of skin conditions, including, dry/oily skin combinations, it can be a factor in certain types of acne, pigmentation, advanced sun damage and fine lines and wrinkles.
Polyglutamic Acid’s ability to protect the NMF is what makes this ingredient a skincare power house. Whilst we are super fans of hyaluronic acid, hold tight for products with polyglutamic Acid, as this trend is fast - going to be mainstream.
