Replenishes NMFHydrates
One of the skin's own Natural Moisturising Factors, replenished directly, hydration the skin already knows how to use.
What it is
Sodium PCA (the salt of pyrrolidone carboxylic acid) is one of the most abundant components of the skin's Natural Moisturising Factor, the built-in mix of water-binding compounds inside surface skin cells. Age, sun and over-cleansing deplete NMF; Sodium PCA restocks it.
How it works
Restocks NMF
Rather than imitating the skin's moisturising system, it replenishes it with a molecule the skin naturally uses, a strong humectant that lives exactly where hydration is needed.
Binds water efficiently
It is highly effective at attracting and holding water in the outer skin, keeping the surface supple.
The evidence
Sodium PCA is a well-established, skin-identical humectant, valued precisely because it replenishes a component the skin makes itself.
Worth knowing
Restocking the skin's own hydration system tends to feel more natural and comfortable than piling on foreign humectants.
