What it is
Sodium PCA is a component of the skin's own natural moisturizing factor and is used cosmetically as a powerful humectant. It attracts water and helps keep the skin hydrated and supple, making it a common conditioning additive in moisturizers and sunscreens. It is water-soluble and works well alongside other humectants and emollients.
Safety & warnings
Sodium PCA is generally well tolerated with low irritation potential and is not a recognized fragrance allergen. As a skin-identical humectant it is widely considered suitable for most skin types, including sensitive skin.
Origin & sourcing
It is produced synthetically but is identical to a substance naturally present in skin as part of its natural moisturizing factor.
