For years, I've been using NaPCA under my moisturizer, on my face, neck and all around my eyes. I don't quite remember how I started with it but I'm under the impression that it helps skin absorb moisure, even from the air. It has a watery texture and sometimes comes mixed with aloe. On this forum I hear hyaluronic acid mentioned a lot and from what I've read, it sounds a lot like NaPCA. I'm wondering which is better and if I should use one or the other. I started with AD CE and feel like I could use it, especially around my eyes. Below are definitions that I found of both products.
Hyaluronic acid: A potent humectant that absorbs moisture from the air to help hydrate your skin. A viscous mucopolysaccharide used as a humectant.
NaPCA: The sodium salt of 2-Pyrrolidone-5-Carboxylic Acid, NaPCA is one of the best moisture binders available, as well as a humectant and an emollient.
For anyone interested, there are definitions of many ingredients used in skincare products on this website:

I don't know how accurate it is but found it interesting. Can anyone tell me the difference???   |

Nanapost,
Can you explain what NaPCA actually is. I have never heard of it. Do you like the moisture it gives your skin.
I spoke to JB today. I was acually going to get some Hyaluronic acid from their salon products. The nice girl on the phone was very nice and said that the prep is doing the same thing. They have a more concentrated Hyaluronic Acid I will be trying down the road.
Don't worry Lori I did not buy a thing!!! |

Winnie,
On the bottle it says its "the natural moisturizing factor found in human skin" It goes on to say old skin contains about half the NaPCA that is found in young skin. It also says that the ability of skin to hold moisture is directly related to the amount of NaPCA in the skin and that its a physiological correction of an age-related deficiency state. It says that it takes moisture from the air as well. I have found that if I use it by itself, my face feels a little sticky but when its under a moisturizer, its fine. I've used it forever as long as I can remember.
When I read somewhere on this board that hyaluronic acid has a watery texture, I wondered if the 2 were somehow related. Then when I found those two definitions that I posted above, I really thought they were similar. If so, NaPCA is really inexpensive, usually found in places like GNC or on the web. Maybe I should ask the folks at J&B. Whatcha think? |
