On the contrary of what many may think when they read the word "acid ", Polyglutamic Acid (PGA) is actually very gentle. A few years ago "Hyaluronic Acid (HA)" was all the rage, but what's this about PGA? Is it here to replace HA?
Here's what we know:
PGA is a polymer of the amino acid Glutamic Acid (GA), hense P-G-A. Repeat after me: " P = Polymer, G = Glutamic, A = Acid , okay bare with me.."
It is a water soluble peptide found in the bacteria of fermented soy beans! "That's right! That iconic, pungeant, sticky, stringy fermented bean you see Japanese folks traditionally eat as part of their breakfast! Talk about gut health!"
As mentioned above it's water-soluble, also edible, non-toxic and biodegradable
This baby retains 4-5 times MORE water than it's friend Hyaluronic Acid "cue gasp!" That's AMAZING!!! 4-5 times MORE!
PGA is a humectant that helps boost the skin's hydration, elasticity and helps seal the moisture thanks to it's outstanding ability to bind to water
Polyglutamic Acid actually helps slow down the aging process of the skin
With all this in mind, we can understand why Polyglutamic Acid is a very much loved product!
It's perfect to use as prevention against fine lines and wrinkles
Pairs beautifully with Hyaluronic Acid for those who have Dry/ Dehydrated skin
Can be used alone if you have more oily skin
Pairs really well with products that strengthen the skin barrier to help lock in the moisture.
PGA is very gentle and safe to use on all skin types, however if you are more sensitive prone I would suggest doing a test patch first!
Here's my ALL time favourite product with Polyglutamic Acid as a key ingredient:
