L-Pyrrolidone Carboxylic Acid (PCA)

( 221 )

PCA (L-Pyrrolidone Carboxylic Acid) is a naturally occurring component of the Natural Moisturizing Factor (NMF). It accounts for 12% of the NMF and helps maintain optimal hydration within the stratum corneum. Without it, the stratum corneum loses elasticity, water, and defense.

PCA is not a trend – it’s a biological constant.

Common Questions

How is PCA different from traditional humectants?

PCA is biomimetic—it doesn’t just attract water, it integrates into the skin’s natural hydration system.

Is PCA suitable for sensitive skin formulations?

Yes, due to its endogenous nature, it shows excellent compatibility.

Can I use PCA in anhydrous systems?

Yes – its crystalline form disperses beautifully in oils and silicones, then activates upon contact with skin’s moisture.
