Last week I wrote a topic piece about polyglutamic acid. Now I want to write a review of the product that has the peptide in it. When I wrote the piece I was just giving the product a first glance. Now I have really tried the product out and I wanted to show you what I think of it. So read on for my review of The Inkey List Polyglutamic Acid.
Everybody wants soft, glowing, dewy skin. The kind that we usually only dream about. Dewy, glowing skin is either usually hard to come by for those of us with dry skin because we lack moisture, or too easy for those of us with oily skin because we have too much sebum.
There is, however, a new molecule on the market that is changing things. Technically it is not a humectant, but a peptide and it is called polyglutamic acid (PGA). It actually holds 5,000 its own weight in water*! Four times that of hyaluronic acid! Polyglutamic acid is a naturally derived ingredient that is formed by the bacterial fermentation of soybeans, called Nattō in Japanese. Like many things that are good for the skin, bacterial fermentation could be great for the skin's microbiome. The ingredient is a natural polymer that was originally used in wound healing. PGA is water soluble, anionic, non-toxic, biodegradable and edible. This molecule is, however, very large and does sit on top of the skin, actually plumping it. Thus it increases luminosity and makes the skin glow. It kind of acts like a natural highlighter on the skin, making it great for skin that is dry, mature and dehydrated (*"These claims have been done in vitro evaluation, and while valuable, are laboratory studies where you are simply mixing the hydrogel into a beaker and unlikely it will behave on the skin in that capacity.", says cosmetic chemist Kelly Dobos "The formulation of a product matters. pH and presence of electrolytes can impact performance.").
Just like HA, polyglutamic acid is also a moisturizing wunderkid. It retains moisture from water and has excellent water-binding properties that allow it to have long-lasting moisture retention capacity. Originally it was used in the medical arena for wound healing and burns. Apparently many skincare advancements start with wound care, because you have to keep burns and wounds moist and hydrated. PGA has anti-aging properties. It improves the elasticity of the skin and can reduce wrinkles, by plumping the skin. PGA is a peptide, and its game changing quality it that it helps to inhibit hyaluronidase, an enzyme which breaks down the skin's naturally occurring hyaluronic acid that we have in our skin. This product can be used with HA, not just instead of hyaluronic acid. Because they both enhance the skin and give a beautiful luminosity, they work in tandem with each other, when one of them alone would only provide half the benefits.
The Inkey List has come out with their version of Polyglutamic Acid. It retails for $14.99 and comes in a 1 fl.oz/30mL bottle. The formula contains 3% high molecular weight PGA and is specifically designed to to enhance skin moisturization on the surface (meaning deep within the epidermis). This helps reduce the look of fine lines, as well as brighten the look of skin. The lightweight silky texture of the serum creates a perfect makeup canvas. 2% invisaskin helps maintains moisture levels in the skin. Use this serum in the AM and PM as the last step before your makeup or right before a moisturizer if you prefer. For long lasting make-up, mix a pea-sized amount in foundation for smooth application.
I wrote a piece about polyglutamic acid & I had purchased and decided to use it. OMG!!!! This stuff is amazing. It immediately plumps the skin and makes it feel so soft and dewy that your skin is like silk. No tightness, no dryness or anything else. This is just as good as my favorite glycerin serum. Yes, you heard me right. It is as good as the $75 Kiehl's Hydro-Plumping Re-Texturizing Serum Concentrate that contains 15% glycerin. It will plump up the epidermis so well that it works just as well as serums that cost three to four times as much and they do the same thing. So, you can essentially save yourself some good money by trying out the The Inkey List Polyglutamic Acid and use it instead. I guarantee it will give you the dewy, glowy look you have been searching for.
I would recommend this serum for any skin type. It is a lightweight clear serum that can be used for anyone, even those with acneic skin. The serum is especially good for those with dry, mature and dehydrated skin types though. This serum really does make a huge difference in how the skin feels. Do you want skin that is hydrated? Dewy and plump? Soft skin? Then this is the serum for you. And the price cannot be beat. The Inkey List has come out with a serum that provides the epidermis with serious hydration in a lightweight serum that works on any skin type with a price point that is seriously inexpensive. Use it twice a day for best results. Use it with your foundation for added moisture and a dewy glow to your skin.
