Calcium PCA Description

Calcium PCA is a mineral electrolyte. More specifically, it is the calcium salt of PCA (pyrrolidone carboxylic acid), which is a key component of skin’s natural moisturizing factor, or NMF. The NMF plays a role in keeping skin’s barrier healthy and intact.

Calcium plays a critical role in skin, influencing how new cells are formed and how they move from the lower layer (dermis) to the surface (epidermis). Within skin’s layers, calcium serves to orchestrate many aspects of maintenance and repair.

Topically, calcium PCA helps replenish skin’s barrier and works as a humectant to draw and hold moisture in skin’s uppermost layers.

In 2019, calcium PCA was deemed safe by the Cosmetic Ingredient Review Expert Panel. Their report surveyed products containing between 0.01-0.2% calcium PCA.
